Terms of Use

Effective: August 28, 2026  ·  Last updated: August 28, 2026

Plain-language summary. Use Lengio for your own language learning. Don't copy, scrape, or reverse-engineer the App. Purchases are processed by Apple or Google, and refunds go through whichever store you bought from. The AI tutor is a machine and gets things wrong — don't rely on it for anything that matters. The App is provided as is. Disputes start with a 60-day conversation, and for US users then go to individual arbitration rather than court. You can stop using Lengio and uninstall it at any time.

These Terms include an arbitration agreement, a class-action waiver, and a one-year limit on bringing claims. Please read Sections 29, 30 and 24 carefully.

1. Agreement to These Terms#

These Terms of Use ("Terms") form a legally binding agreement between you and Lengio ("Lengio", "we", "us", or "our") governing your access to and use of the Lengio mobile application for iOS and Android (the "App"), the lengio.app website (the "Site"), and any related services we provide (together, the "Services").

By downloading, installing, accessing, or using the Services, you confirm that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated here by reference. If you do not agree, you must not use the Services.

These Terms also apply to anyone who accesses the Services on your behalf.

2. Who You Are Contracting With#

The Services are operated by Nexios Media LLC, a limited liability company organised under the laws of the State of Illinois, United States, trading as "Lengio" (nexios-media.com). References to "Lengio", "we", "us", and "our" in these Terms mean that company.

Nexios Media LLC maintains a registered agent in Illinois as required by state law, through whom formal service of process may be made. For every other purpose — including notices under this document, privacy requests, and support — please use support@lengio.app, which we monitor and which is the fastest way to reach a person.

Your agreement is with that company alone. It is not with Apple Inc., Google LLC, or any other platform, store, or service provider through which you obtain or use the App, except to the limited extent set out in Apple App Store Terms and Google Play Terms.

3. Eligibility & Age Requirements#

You must be at least 13 years old, or the minimum age of digital consent in your jurisdiction (16 in some EU member states), to use the Services. If you are under 18 (or the age of majority where you live), you confirm that a parent or legal guardian has reviewed these Terms and agrees to them on your behalf, and that they accept responsibility for your use of the Services and for any charges you incur.

By using the Services you also represent that you are not located in, or a national or resident of, a jurisdiction subject to comprehensive sanctions by your home country, and that you are not on any restricted-parties list (see Export Controls).

4. Description of the Services#

Lengio is a vocabulary-learning application that pairs words in your target language with images, native-speaker audio, and example sentences, and includes an optional AI speech-partner feature that lets you practise spoken conversations with an AI tutor. Core vocabulary review functions locally on your device once language packs are downloaded; the AI speech partner, language-pack downloads, conversation videos, in-app purchases, in-app image search, and app-store updates require an internet connection.

The Services are a self-directed study aid. They are not a school, a course of instruction, a tutoring service, a certification body, or a translation service, and no teacher–student, tutor–student, or professional relationship of any kind is created by your use of them.

Features, content, and availability of the Services may change over time, and may differ between iOS and Android because of platform capabilities and store policies. We make no commitment that any particular feature will remain available indefinitely or be available identically on every platform or in every country.

5. Your License to Use the App#

Subject to your compliance with these Terms, Lengio grants you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to download and use the App on a mobile device that you own or control, for your own personal, non-commercial language-learning purposes.

Where you obtained the App from the Apple App Store, that licence is further limited to use on an Apple-branded product as described in Apple App Store Terms. Where you obtained the App from Google Play, your use is also subject to the Google Play Terms of Service as described in Google Play Terms.

This licence is for use of the App in object-code form only. We retain all rights, title, and interest in and to the App not expressly granted to you under these Terms.

You may not, and you may not permit any third party to:

  • Copy, reproduce, modify, adapt, translate, or create derivative works of the App or its content.
  • Distribute, lease, lend, sell, sublicense, rent, or otherwise transfer the App or rights to it.
  • Reverse-engineer, decompile, disassemble, or attempt to derive the source code, except to the extent that applicable law expressly permits (and not before notifying us).
  • Remove, obscure, or alter any proprietary notices, branding, or marks.
  • Circumvent, disable, or interfere with any licensing check, entitlement check, paywall, usage limit, or technical protection measure, or use a modified, repackaged, or unofficially distributed build of the App.
  • Use the App to develop a competing product or service, or to benchmark performance for publication without our written consent.
  • Extract, scrape, or accumulate the vocabulary data, audio recordings, imagery, lesson content, or AI outputs of the App to build or improve any dataset, model, or product.
  • Share, resell, or make available to others any paid entitlement, or use a single purchase to provide access to people outside the sharing arrangements permitted by the store you purchased from.
  • Use the App in connection with any unlawful, infringing, or harmful activity.

This licence terminates automatically if you breach any of these Terms (see Termination).

6. Account-Free Use & Local Data#

Lengio does not require you to create an account. Your vocabulary progress, bookmarks, statistics, personal photos, and preferences are stored locally on your device.

We do not hold a copy of your study data, and we cannot recover it. If it is lost — for example after uninstalling the App, factory-resetting or losing your device, switching between iOS and Android, clearing app storage, or restoring a device without a backup — it is gone permanently. This is a direct consequence of the account-free, on-device design, and you accept it as a condition of using the Services.

Keeping a backup is your responsibility. On iOS this normally means iCloud Backup; on Android it normally means Google's Android Backup Service. Both are operated by Apple and Google respectively under their own terms, not by us, and we make no representation that either will capture your Lengio data, retain it, or restore it successfully. Progress does not transfer between iOS and Android. See the Privacy Policy for details of what is stored where.

7. User Content & Personal Photos#

"User Content" means any content you provide to or through the Services, including photos you attach to vocabulary entries, text you type or speak into the AI Speech Partner, and the content of any support correspondence.

Ownership. You retain all ownership rights in your User Content. Personal photos you attach inside the App stay on your device.

Limited license to us. Only where you transmit User Content to us — for example by emailing screenshots to support, or by sending a message to the AI Speech Partner, which is relayed through a server we operate — you grant us a worldwide, non-exclusive, royalty-free, sublicensable, revocable licence to host, store, transmit, reproduce, and use that content solely as necessary to respond to your request, deliver the Services, comply with law, or enforce these Terms. Photos you attach inside the App but do not send to us are not covered by this licence because we never receive them.

Your warranties. You represent and warrant that you own or have all rights necessary to share any User Content you submit to us, that it does not infringe any third-party right, violate any law, or contain unlawful material, and that you have obtained any consent required from any person depicted in a photograph you attach or send to us.

Removal. You may withdraw User Content from our possession at any time by requesting deletion from support@lengio.app. We may also remove or refuse to process content that we believe violates these Terms or applicable law.

8. Acceptable Use & Prohibited Conduct#

You agree to use the Services only for lawful purposes and in compliance with these Terms. You will not, and will not attempt to:

  • Access or use the Services in violation of any applicable law, regulation, or third-party right.
  • Use the Services to send malware, harmful code, or any data that may interfere with the Services or another user's device.
  • Scrape, harvest, or extract content from the App or Site by automated means.
  • Probe, scan, or test the vulnerability of the Services without our prior written permission.
  • Attempt to circumvent any security feature, technical protection, rate limit, usage quota, or paywall of the Services.
  • Use the Services to harass, threaten, defame, or harm any person.
  • Impersonate any person or entity, or misrepresent your affiliation with Lengio.
  • Resell, sublicense, or commercially exploit the Services without our written consent.
  • Use the Services in any way that could damage, disable, overburden, or impair them, including automated or scripted interaction with the AI Speech Partner or with our servers.

We may investigate suspected violations and take any action we consider appropriate, including rate-limiting, suspending or terminating your access (see Termination) and cooperating with law-enforcement authorities.

9. AI Speech Partner — Nature & Limitations#

The AI Speech Partner (also called the AI Chat Coach) generates its replies using a third-party large language model. It is software, not a person, and it is not supervised, reviewed, or approved by a human before you see it.

Output may be wrong. AI-generated text and pronunciation feedback may be inaccurate, incomplete, out of date, grammatically incorrect, regionally inappropriate, culturally insensitive, nonsensical, or offensive. It may confidently state things that are false. It may produce translations that are wrong in ways a beginner cannot detect. We do not review, verify, endorse, or take responsibility for any output, and no output is a statement by Lengio.

Do not rely on it for anything that matters. You must not rely on AI output as a substitute for professional advice or for a qualified human translator or interpreter. Without limitation, do not rely on it for legal, medical, financial, tax, immigration, visa, safety, emergency, employment, academic, or travel-critical purposes, or for any communication where an error could cause loss, harm, offence, or legal consequence. Verify anything important with a qualified human.

Do not enter sensitive information. Do not speak or type personal, confidential, financial, health, or otherwise sensitive information about yourself or any other person into the AI Speech Partner. Content you submit is transmitted to our AI provider to generate a reply, as described in the Privacy Policy.

Your obligations. You will not use the AI Speech Partner to generate, solicit, or distribute unlawful, infringing, sexually explicit, hateful, harassing, or deceptive content; to attempt to bypass, jailbreak, or manipulate its safety controls or system instructions; to extract its prompts or underlying model; to generate content for use in training or evaluating any other machine-learning model; or to conduct automated or high-volume querying. Doing so is a material breach of these Terms.

Availability. The feature depends on a third-party provider and on your internet connection. It may be unavailable, rate-limited, changed, or discontinued at any time, and the underlying model may be replaced. Usage limits apply, and differ between the free tier and Lengio Plus. No specific model, capability, response quality, response time, or number of messages is guaranteed.

No liability for output. To the maximum extent permitted by law, Lengio has no liability arising out of or relating to AI-generated output, your reliance on it, or any action you take or refrain from taking because of it. This is a material part of the bargain and is reflected in the pricing of the Services.

10. Educational Content & No Guaranteed Outcomes#

Vocabulary entries, translations, example sentences, audio recordings, conversation videos, grammar explanations, and cultural notes are provided for general educational purposes. Language is regional, contextual, and constantly changing: a word that is neutral in one country may be inappropriate in another, a register that is polite in one setting may be rude in another, and any translation involves judgement. Content may contain errors, omissions, regional bias, or outdated usage.

You are responsible for how you use what you learn. We are not responsible for any misunderstanding, offence, embarrassment, contractual consequence, or other loss arising from your use of a word, phrase, or translation obtained from the Services.

No guaranteed outcome. Language learning depends on your time, effort, aptitude, prior knowledge, and consistency. We do not promise, and nothing in the Services or our marketing should be read as promising, that you will reach any particular level of proficiency, achieve fluency, pass any examination, or learn within any particular period. Streaks, levels, progress indicators, word counts, and similar figures are motivational features, not measurements of proficiency.

Not a qualification. Lengio is not an accredited educational institution. Nothing in the App constitutes a certificate, diploma, CEFR assessment, or evidence of proficiency for any employer, university, immigration authority, or other body, and must not be presented as such.

The App lets you replace the picture on a vocabulary card with a photo from your own library, or with an image found through an in-app web image search operated by a third party (currently Google Image Search).

Search results are generated by that third party. We do not select, host, screen, moderate, filter, or endorse them, and we cannot guarantee that results will be accurate, appropriate, safe for work, or free of material that some users find objectionable. Images returned by a search may be protected by copyright or other rights held by others.

You are solely responsible for any image you choose to save to a card, and for ensuring you have the right to use it. You must not save images that are unlawful, that depict minors inappropriately, or that infringe another person's intellectual-property or privacy rights. Saved images are stored on your device only. Your use of the search feature is subject to the third party's own terms and privacy policy.

Where the App displays photography, illustration, audio, or video licensed from third parties, that content remains the property of its owners and is licensed to you only as part of your permitted use of the App.

12. Safe & Attentive Use#

Lengio is designed for short study sessions, but it still asks for your attention, your eyes, your ears, and sometimes your voice.

Do not use the Services while driving, cycling, operating machinery, crossing a road, or doing anything else that requires your attention. Obey all applicable laws about device use while driving. Do not use the App in a way that puts you or anyone else at risk.

Audio content is played at a volume you control. Prolonged listening at high volume can damage your hearing; set a safe level and take breaks. If you experience discomfort, eye strain, headaches, or any other symptom while using the App, stop and consult a qualified professional. If you have a medical condition that may be affected by screen use, seek medical advice before using the Services.

13. Beta & Experimental Features#

We may make features available that are labelled beta, preview, experimental, or similar, or that are offered to a subset of users for evaluation. Those features are provided for testing, may be unstable or incomplete, may change or be withdrawn without notice, and may result in loss of data associated with them. They are provided "as is" with no warranty of any kind, and any service level, availability expectation, or support commitment that would otherwise apply does not apply to them.

14. Intellectual Property#

All rights, title, and interest in and to the Services — including the software, design, user interface, vocabulary data, illustrations, photography, audio recordings, video, the "Lengio" name and logo, and all related trademarks — are and will remain the exclusive property of Lengio and its licensors. The Services are protected by copyright, trademark, and other intellectual-property laws of the United States, the European Union, the United Kingdom, and other jurisdictions.

Nothing in these Terms transfers any intellectual-property rights to you, except the limited licence in Section 5. Any unauthorised use of our marks, logos, or content is strictly prohibited. Apple, App Store, iPhone, iPad and iOS are trademarks of Apple Inc.; Google, Google Play and Android are trademarks of Google LLC. Use of those marks on the Services is nominative and does not imply endorsement.

15. Feedback#

If you send us suggestions, ideas, feature requests, or other feedback ("Feedback"), you grant us a perpetual, worldwide, royalty-free, sublicensable, irrevocable licence to use the Feedback for any purpose without any obligation or compensation to you. We are free to use Feedback even if it is similar to ideas we develop independently. You waive any moral rights in Feedback to the extent permitted by law.

16. In-App Purchases & Subscriptions#

The App may offer optional paid content, features, or subscriptions ("In-App Purchases"), marketed as Lengio Plus. All In-App Purchases are sold, delivered, billed, and managed by the store you downloaded the App from — Apple through the App Store, or Google through Google Play. We never see or handle your payment card details.

Your purchase is therefore subject to that store's terms — Apple's Media Services Terms, or the Google Play Terms of Service — and to any subscription terms shown at the point of sale, in addition to these Terms.

Automatic renewal — please read. If you buy a subscription rather than a one-time lifetime purchase:

  • Payment is charged to your Apple ID or Google Account at confirmation of purchase.
  • Your subscription renews automatically at the then-current price for the same period, and will keep renewing and charging you, until you cancel.
  • To avoid being charged, cancel at least 24 hours before the end of the current period.
  • To cancel on iOS: Settings → your name → Subscriptions → Lengio → Cancel Subscription.
    To cancel on Android: Google Play → profile icon → Payments & subscriptions → Subscriptions → Lengio → Cancel subscription. You can also cancel at play.google.com/store/account/subscriptions.
  • Cancellation takes effect at the end of the current paid period. You keep access until then, and no partial refund is issued for unused time except where the law requires one.
  • Any free trial converts to a paid subscription automatically when it ends unless you cancel before it expires. The trial length and the price that follows are shown on the purchase screen before you confirm.
  • Uninstalling the App does not cancel a subscription. You must cancel through the store.

Prices and price changes. Prices are shown in your local currency on the purchase screen before you confirm, and may vary by country and over time. We may change the price of paid content or subscriptions. A price change to an active subscription takes effect at the start of the next billing period and will be notified to you as required by the relevant store's policies and applicable law; where the law or the store requires your consent to the new price, your subscription will not renew at the new price without it. Existing one-off purchases are not retroactively re-billed.

Lifetime purchases. Where a purchase is described as "lifetime", this means for as long as we continue to offer the App and the relevant feature, and does not create any obligation to operate the Services indefinitely. If we discontinue the Services entirely, Section 23 applies.

Taxes. Prices may include applicable VAT, sales tax, or other levies. Apple or Google collects and remits these where applicable.

Entitlement checks. The App verifies paid entitlements with the relevant store. If a purchase is refunded, charged back, cancelled, or cannot be verified, we may withdraw the corresponding access.

17. Refunds & Cancellations#

Refunds are administered by the store that sold you the purchase. We have no ability to issue, reverse, or expedite a charge on either platform, and asking us will not be faster than going to the store directly.

  • Apple App Store — visit reportaproblem.apple.com, sign in with your Apple ID, find the Lengio purchase, and choose Request a Refund. Apple decides the outcome under its own policy.
  • Google Play — visit play.google.com/store/account/orderhistory or use Google Play → profile icon → Payments & subscriptions → Budget & order history, and request a refund. Google generally offers self-service refunds within a short window after purchase; after that, refunds are at Google's discretion under Google Play's refund policy.

EU, UK, and Swiss consumers, and consumers elsewhere with equivalent statutory rights, may have additional withdrawal or cancellation rights — see EU/UK/Swiss Consumer Rights. Nothing in this section limits those rights.

18. App Updates & Service Changes#

We may, from time to time, release updates to the App or modify, suspend, or discontinue any feature of the Services. We may do so to add or remove functionality, fix bugs, respond to a change in a third-party service, comply with law or store policy, or for any other reason. Updates are distributed through the App Store or Google Play and may require a current operating-system version or a recent device.

Older versions of the App may stop working when a server-side interface changes. We will use reasonable efforts to maintain meaningful access to material content you have paid for, but we cannot guarantee perpetual availability of any specific feature, language pack, video, or model.

19. Third-Party Links & Services#

The Services may link to or embed third-party websites, applications, or resources, including the Apple App Store, Google Play, store refund pages, and the in-app image search. Those resources are independent of Lengio. We do not control them, do not endorse their content, and are not responsible for their availability, accuracy, security, or privacy practices. Your access to and use of any third-party resource is at your own risk and subject to the terms and policies of that resource.

20. Apple App Store Terms#

The following terms apply if you obtained the App through Apple's App Store:

  • Acknowledgement. These Terms are concluded between you and Lengio, not Apple. Apple is not responsible for the App or its content.
  • Scope of licence. The licence granted to you is limited to a non-transferable licence to use the App on an Apple-branded product that runs Apple's operating system and that you own or control, and as permitted by the Usage Rules in the Apple Media Services Terms (including, e.g., the Family Sharing rules).
  • Maintenance and support. Lengio is solely responsible for providing any maintenance and support for the App, as required by these Terms or applicable law. Apple has no obligation to furnish any maintenance or support for the App.
  • Warranty. Lengio is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the App fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price (if any) for the App. To the maximum extent permitted by law, Apple will have no other warranty obligation whatsoever with respect to the App.
  • Product claims. Lengio, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your use of it, including product liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims arising under consumer-protection or similar law.
  • Intellectual-property claims. In the event of any third-party claim that the App or your possession and use of it infringes that third party's intellectual-property rights, Lengio (not Apple) will be solely responsible for the investigation, defence, settlement, and discharge of such claim.
  • Legal compliance. You represent that you are not located in a country that is subject to a US Government embargo, or that has been designated as a "terrorist-supporting" country, and that you are not on any US Government list of prohibited or restricted parties.
  • Third-party beneficiary. Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

21. Google Play Terms#

The following terms apply if you obtained the App through Google Play:

  • Acknowledgement. These Terms are concluded between you and Lengio, not Google. Google is not a party to these Terms and is not responsible for the App, its content, or any In-App Purchase.
  • Google Play terms. Your download and use of the App is additionally governed by the Google Play Terms of Service. Where these Terms conflict with the Google Play Terms of Service in relation to your use of Google Play, the Google Play Terms of Service control as to that conflict.
  • Maintenance and support. Lengio, not Google, is solely responsible for maintenance and support of the App, and for addressing any claim relating to the App, including product liability, consumer-protection, and intellectual-property claims.
  • Billing and refunds. In-App Purchases are billed by Google through Google Play Billing and are refundable only in accordance with Google Play's refund policy, as described in Refunds & Cancellations.
  • Device compatibility. Google does not warrant that the App is compatible with your device. Availability may be restricted by device, Android version, or country.

22. Disclaimer of Warranties#

To the maximum extent permitted by applicable law, the Services are provided "as is" and "as available," with all faults, and Lengio, its affiliates, and its licensors expressly disclaim all warranties of any kind, whether express, implied, statutory, or otherwise, including any implied warranty of merchantability, fitness for a particular purpose, title, accuracy, quiet enjoyment, and non-infringement.

Without limiting the foregoing, we do not warrant that: (a) the Services will meet your requirements; (b) the Services will be uninterrupted, timely, secure, or error-free; (c) any content, translation, audio, or AI output is complete, accurate, or current; (d) any defect will be corrected; or (e) the Services will be free of loss or corruption of data.

You acknowledge that language learning depends on factors beyond our control and that we do not guarantee any particular learning outcome (see Section 10). Some jurisdictions do not allow the disclaimer of certain implied warranties; the disclaimers above apply only to the extent permitted by law, and nothing here affects the statutory rights of consumers under Section 31.

23. Limitation of Liability#

To the maximum extent permitted by law:

  • In no event will Lengio, its affiliates, officers, members, employees, agents, suppliers, or licensors be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including loss of profits, loss of data, loss of study progress, loss of goodwill, cost of substitute services, or business interruption, however caused and on any theory of liability (whether contract, tort, strict liability, or otherwise), even if advised of the possibility of such damages.
  • Our aggregate liability arising out of or relating to these Terms or the Services, regardless of the form of action, will not exceed the greater of (i) the total amount you actually paid to Apple or to Google for the App and in-App content in the 12 months immediately preceding the event giving rise to the claim, or (ii) USD 50.

These limits apply in aggregate across all claims, and not per claim. They apply even if any limited remedy fails of its essential purpose, and they survive termination of these Terms.

Some jurisdictions do not allow the exclusion or limitation of liability for certain damages — including liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for gross negligence or wilful misconduct. Those exclusions do not apply to you to the extent prohibited, and the remaining limitations continue to apply.

24. Time Limit for Bringing Claims#

To the maximum extent permitted by law, any claim or cause of action arising out of or relating to the Services or these Terms must be filed within one (1) year after the claim arose. A claim filed after that period is permanently barred.

This section does not apply where the applicable law does not permit a contractual shortening of the limitation period, and it does not apply to consumers resident in the European Economic Area, United Kingdom, or Switzerland (see Section 31), whose statutory limitation periods apply instead.

25. Indemnification#

To the extent permitted by applicable law, you agree to defend, indemnify, and hold harmless Lengio, its affiliates, and their officers, directors, members, employees, contractors, and agents from and against any and all claims, liabilities, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or in any way connected with: (a) your access to or use of the Services; (b) your violation of these Terms; (c) your violation of any third-party right, including any intellectual-property or privacy right; (d) any User Content you submit to us; or (e) your use of, or reliance on, any output of the AI Speech Partner.

We reserve the right, at our own expense, to assume the exclusive defence and control of any matter for which you are required to indemnify us, in which case you agree to cooperate with our defence. This section does not apply to consumers to the extent prohibited by the mandatory consumer law of their country of residence.

26. Suspension & Termination#

You may stop using the Services at any time by uninstalling the App. Uninstalling does not cancel a subscription — see Section 16.

We may suspend or terminate your access to all or part of the Services at any time, with or without notice, if we reasonably believe that: (a) you have breached these Terms; (b) doing so is required by law or any competent authority; (c) it is necessary to protect the Services, other users, or a third party from harm, fraud, or abuse; or (d) providing the Services to you is no longer commercially viable. Where the termination is not for breach and you hold an unexpired paid entitlement, we will use reasonable efforts to give advance notice and, where the law requires it, a pro-rata refund through the relevant store.

Termination will not affect any right, remedy, obligation, or liability that has accrued before termination. Sections that by their nature should survive termination will survive (see Section 40).

27. Governing Law & Jurisdiction#

These Terms and any non-contractual obligations arising out of or in connection with them are governed by the laws of the State of Illinois, United States, without regard to its conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Subject to the arbitration and dispute-resolution provisions below, the state and federal courts located in Cook County, Illinois will have exclusive jurisdiction to settle any dispute arising out of or in connection with these Terms, and you consent to personal jurisdiction and venue there.

This section does not deprive you of the protection of any mandatory consumer-protection law of your country of residence, and does not prevent a consumer from bringing proceedings in their local courts where the law gives them that right.

28. Informal Dispute Resolution#

Before initiating any formal dispute, you and Lengio agree to first try in good faith to resolve the dispute by informal negotiation for at least 60 days. To begin, send a written description of the dispute, your name and contact details, the Services at issue, and the relief you seek to support@lengio.app with the subject line "Dispute Notice". If we have a dispute with you we will send our notice to the email address on file with our support team. The 60-day period runs from receipt of the notice.

This process is a condition precedent to commencing arbitration or litigation. The limitation period in Section 24 is tolled while it runs. A notice must be personal to you; a notice submitted on behalf of multiple claimants does not satisfy this section.

29. Binding Arbitration (US Users)#

This section applies only if you reside in the United States. It does not apply to consumers resident in the EEA, United Kingdom, or Switzerland, or anywhere else where a pre-dispute consumer arbitration agreement is unenforceable.

You and Lengio agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Services that has not been resolved through informal resolution under Section 28 will be resolved by final and binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules then in effect. The arbitration will be conducted in English by a single arbitrator, and may be conducted by phone, video conference, written submissions, or in person at a location reasonably convenient to you.

The Federal Arbitration Act governs the interpretation and enforcement of this section. The arbitrator has exclusive authority to resolve any dispute about the formation, applicability, interpretation, or enforceability of this section, except that a court of competent jurisdiction has authority to decide enforceability of the class-action waiver.

Carve-outs. Either party may (a) bring an individual claim in small-claims court if it qualifies, and (b) seek injunctive or other equitable relief in a court of competent jurisdiction to prevent actual or threatened infringement or misappropriation of intellectual property. Seeking such relief does not waive this arbitration agreement.

Small claims and fees. For claims under USD 10,000, you may choose to have the arbitration conducted by telephone or solely on written submissions. Arbitration fees are allocated under the AAA Consumer Arbitration Rules. The arbitrator may grant any remedy available in court, but only on an individual basis and only in favour of the individual party seeking relief. Judgement on the award may be entered in any court of competent jurisdiction. The arbitration and its outcome are confidential except as needed to enforce the award or as required by law.

Coordinated filings. If 25 or more claimants submit demands for arbitration raising substantially similar claims and represented by the same or coordinated counsel, the demands will be administered in staged batches of no more than 50, with a single arbitrator appointed per batch and one set of filing fees per batch. The limitation period in Section 24 is tolled for claims awaiting a later batch. If a court finds this paragraph unenforceable, it is severed and the remainder of this section stands.

30-day opt-out. You may opt out of this arbitration agreement within 30 days of first accepting these Terms by sending written notice to support@lengio.app with the subject line "Arbitration Opt-Out", including your name and an explicit statement that you wish to opt out. Opting out will not affect any other part of these Terms and will not disadvantage you in any way.

If any amendment to this section would materially affect a claim of which you have already given notice, that claim is governed by the version in force when the notice was given.

30. Class-Action & Jury-Trial Waiver#

To the maximum extent permitted by law, you and Lengio each agree that any dispute will be brought only in an individual capacity, and not as a plaintiff or class member in any purported class, collective, consolidated, private-attorney-general, or representative proceeding. The arbitrator may not consolidate the claims of more than one person and may not preside over any form of representative or class proceeding.

You and Lengio also waive any right to a jury trial on any claim, to the extent permitted by law. If a court decides that any part of this section is unenforceable as to a particular claim or request for relief, that claim or request will be severed and heard in court while all other claims proceed in arbitration.

31. EU/UK/Swiss Consumer Rights#

If you are a consumer resident in the European Economic Area, United Kingdom, or Switzerland, nothing in these Terms — including the disclaimers, liability cap, limitation period, governing-law clause, class waiver, or arbitration provisions — affects your mandatory statutory rights, including any rights you have to: (a) bring proceedings in the courts of your country of residence; (b) the non-derogable law of your country of residence applying; (c) statutory guarantees about the conformity of digital content and digital services; or (d) any cooling-off or withdrawal right.

Right of withdrawal. Where you have a statutory right to withdraw from a purchase of digital content within 14 days, that right may be lost once supply of the digital content begins with your express prior consent and your acknowledgement that you thereby lose the right. The relevant store obtains that consent at the point of sale and administers the refund.

Online dispute resolution. We are not obliged to, and do not commit to, participate in dispute-resolution proceedings before a consumer arbitration board. You may nonetheless contact your national consumer authority or an alternative dispute-resolution body available to you.

32. DMCA & Copyright Complaints#

We respect the intellectual-property rights of others. If you believe that material made available through the Services infringes your copyright, please send a notice under the Digital Millennium Copyright Act to support@lengio.app with the subject line "DMCA Notice". Include: (a) your physical or electronic signature; (b) identification of the copyrighted work claimed to be infringed; (c) identification of the allegedly infringing material with sufficient detail to locate it; (d) your contact information; (e) a statement that you have a good-faith belief that the disputed use is not authorised; and (f) a statement, under penalty of perjury, that the information in the notice is accurate and that you are the copyright owner or authorised to act on the owner's behalf.

We will respond to valid notices in accordance with applicable law and may remove or disable access to the material. You may submit a counter-notice if you believe material was removed in error. Submitting a false notice may subject you to liability, and we may decline to act on repeat bad-faith notices.

33. Export Controls & Sanctions#

The Services may be subject to US, EU, UK, and other export-control and economic-sanctions laws. You agree not to export, re-export, or transfer the App or any related technology to any prohibited destination, person, or end use without obtaining required government authorisations. You represent that you are not located in, under the control of, or a national or resident of any country subject to comprehensive sanctions, and that you are not listed on any government list of prohibited or restricted parties.

34. Government Users#

If you access the Services on behalf of a US Government entity, the Services are "commercial computer software" and "commercial computer software documentation" as those terms are used in FAR 12.212 and DFARS 227.7202, and are licensed to the Government as commercial items, with only those rights granted to all other end users under these Terms.

35. Changes to These Terms#

We may revise these Terms from time to time. The "Last updated" date at the top of this page indicates when the latest version took effect. If we make material changes, we will provide reasonable advance notice — for example through the App, on this page, or by email to a known support contact — before the change becomes effective.

Your continued use of the Services after a revision becomes effective constitutes acceptance of the revised Terms. If you do not agree, you must stop using the Services and may cancel any subscription through your store. Changes will not apply retroactively to a dispute of which we have notice on the effective date.

36. Severability, Waiver & Assignment#

Severability. If any provision of these Terms is held invalid, illegal, or unenforceable, the remaining provisions will continue in full force and effect, and the invalid provision will be modified to the minimum extent necessary to make it enforceable while best preserving the parties' intent.

No waiver. Our failure to enforce any provision is not a waiver of our right to do so later.

Assignment. You may not assign or transfer these Terms or your rights or obligations without our prior written consent. We may assign these Terms (in whole or in part) to an affiliate or to a successor in connection with a merger, acquisition, reorganisation, or sale of assets, on notice to you. Any prohibited assignment is void.

Independent parties. Nothing in these Terms creates a partnership, joint venture, agency, franchise, or employment relationship between you and Lengio.

Headings and interpretation. Headings are for convenience only. "Including" means "including without limitation". No rule of construction against the drafter applies.

37. No Third-Party Beneficiaries#

Except for Apple Inc. and its subsidiaries as expressly provided in Section 20, and for the indemnified persons named in Section 25, these Terms confer no right or benefit on any third party and no third party may enforce any of their provisions.

38. Notices & Communications#

You consent to receive electronic communications from us and you agree that all agreements, notices, disclosures, and other communications we provide electronically satisfy any legal requirement that they be in writing. We may provide notices through the App, by posting on the Site, or to an email address you have provided to us. You may send notices to us at support@lengio.app. Formal service of process is made on our Illinois registered agent as described in Section 2.

39. Force Majeure#

We will not be liable for any failure or delay in performance caused by circumstances beyond our reasonable control, including acts of God, war, terrorism, riots, embargoes, acts of civil or military authority, fire, floods, earthquakes, accidents, network or cloud-provider failures, failure or withdrawal of a third-party service on which the Services depend, strikes, pandemics, or governmental action.

40. Survival & Entire Agreement#

Sections that by their nature should survive termination — including those relating to ownership, User Content licences, AI limitations, disclaimers, indemnities, liability limits, the limitation period, dispute resolution, arbitration, governing law, and these miscellaneous provisions — will survive.

These Terms, together with the Privacy Policy and any policies or terms expressly incorporated by reference, constitute the entire agreement between you and Lengio with respect to the Services and supersede all prior or contemporaneous agreements, communications, and proposals. To the extent that any portion of these Terms conflicts with Apple's App Store terms or the Google Play Terms of Service with respect to your use of the App obtained from that store, the store's terms control as to that conflict.
