Terms of Service

These Terms of Service ("Terms") are an agreement between you and Acrylic Code Inc., a corporation based in Alberta, Canada ("Acrylic Code", "we", "us"). They govern your use of the Ling Lang Teacher mobile application, its optional LingLang Pro subscription, and the relay service that supports them (together, "the app"). By installing or using the app you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the app.

Nothing in these Terms takes away rights you have under the Consumer Protection Act (Alberta) or any other consumer protection law that applies to you and cannot be waived. Where these Terms and such a law conflict, the law wins.

1. Who may use the app

You must be at least 13 years old to use the app. If you are under the age of majority where you live (18 in Alberta), a parent or guardian must agree to these Terms on your behalf and is responsible for your use. The app is not directed at children under 13.

2. What the app is

Ling Lang Teacher is a language-learning app built around an AI teacher. The teacher's conversations, explanations, corrections, translations, spoken audio and lesson plans are generated by artificial-intelligence services. They are produced automatically and are not reviewed by a human before you see them.

The app is a learning aid. It is not a substitute for a qualified human teacher, an accredited course, a certified translation or interpretation, or professional advice of any kind, and it does not certify your proficiency in any language. AI output can be wrong, incomplete, out of date or inappropriate despite our efforts. Use your judgment, and do not rely on the app where an error could cause harm, such as medical, legal, safety or financial situations.

3. Your licence to use the app

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the app on devices you own or control, for your own non-commercial language learning, in accordance with these Terms and the rules of the store you got it from (Google Play or the Apple App Store). Family Sharing, where the store offers it, is permitted within the store's rules.

You may not:

• copy, modify, translate, reverse engineer, decompile or create derivative works of the app, except where the law expressly allows it despite this restriction;
• sell, rent, lease, sublicense, redistribute or make the app available to others as a service;
• bypass or interfere with usage limits, subscription checks, app-integrity checks or any other security or metering feature;
• use automated tools or scripts to drive the app or its relay service, or use the relay service for anything other than the app;
• use the app to generate or spread content that is unlawful, defamatory, hateful, harassing, sexually explicit involving minors, or that infringes someone else's rights;
• use the app in a way that harms it, us, our service providers or other users, including attempting to extract our providers' credentials or overload our services.

We may suspend or block an installation that breaks these rules.

4. Your content and your data

You keep all rights in the text and speech you provide to the app. To operate the app, you give us and the service providers named in the Privacy Policy permission to process that content for the sole purpose of generating the teacher's responses, transcriptions and speech, applying usage limits, and improving the app as described in the Privacy Policy.

Your learning data (profile, conversations, vocabulary, progress) is stored only on your device. There is no account and no cloud copy. If you uninstall the app, wipe its data, or lose or replace your device, that data is gone and we cannot recover it. Use the in-app backup and export features to protect it. You are responsible for the backup files you create.

5. Free use and LingLang Pro

The app can be used for free with daily limits on teacher messages and a standard voice. LingLang Pro is an optional auto-renewing monthly subscription that raises the daily message limit and enables premium voice quality. What Pro includes may change over time; we will describe the current benefits in the app and in the store listing before you buy.

Billing. Subscriptions are sold and billed by the app store you bought them through, Google Play or the Apple App Store, under that store's terms. We never see your payment details. The price is shown in the store's purchase flow in your local currency before you confirm.

Renewal and cancellation. Your subscription renews automatically each month at the price shown at purchase unless you cancel through the store at least 24 hours before the end of the current period. Cancelling stops future renewals; you keep Pro until the end of the period you have paid for. You cancel in your Google Play or Apple Account subscription settings, which the app links to from Settings. Deleting the app does not cancel a subscription.

Price changes. If we change the subscription price, the store will tell you in advance and, where the store requires it, ask for your consent before the new price applies. If you do not agree, cancel before the change takes effect.

Refunds. Refunds are handled by the store under its policies, subject to any rights you have under applicable consumer protection law. Contact Google Play or Apple for a refund request.

Verification. To confirm a subscription, the app sends the store's purchase token or transaction to our relay service, which checks it with the store and keeps the record described in the Privacy Policy. If a purchase cannot be verified, is refunded, or is reported by the store as revoked, Pro features are withdrawn.

Restoring. Pro is tied to the store account that bought it. Use the app's restore option after reinstalling or changing devices. Restoring requires the store to confirm the purchase.

6. Availability, limits and changes

We work to keep the app available, but it depends on third-party AI, speech, analytics and store services and on your network. It may be unavailable, slow or degraded at times, and we may impose or change usage limits, including for free use, to keep the service sustainable. We may add, change or remove features. If we retire the app or a feature entirely, we will give reasonable notice where practical, and subscribers will not be charged for periods after the paid feature stops being available.

7. Third-party services and terms

The app relies on services from other companies, including Google (Gemini AI and Cloud Text-to-Speech), Inworld AI (voice synthesis), Amplitude (usage analytics), Cloudflare (our relay), Google Play and the Apple App Store. Your use of the app must also comply with those providers' applicable terms. We are not responsible for third-party services, and their handling of data is governed by their own policies as described in the Privacy Policy.

8. Intellectual property

The app, the relay service, the teacher's design and prompts, the lesson structures, the app's text, artwork, audio and code, and the names "Ling Lang", "LingLang Teacher", "LingLang Pro" and "Acrylic Code" are owned by Acrylic Code Inc. or its licensors and are protected by copyright, trademark and other laws of Canada and other countries. These Terms give you no ownership of any of it. Feedback you send us may be used by us without obligation to you.

9. Disclaimer of warranties

To the extent permitted by applicable law, the app is provided "as is" and "as available". We make no warranty, express or implied, that the app will be accurate, error-free, uninterrupted, secure, or fit for a particular purpose, or that AI-generated content will be correct. Some jurisdictions, including Alberta under certain consumer protection laws, do not allow the exclusion of certain warranties, so parts of this section may not apply to you.

10. Limitation of liability

To the extent permitted by applicable law:

• we are not liable for indirect, incidental, special, consequential or punitive damages, or for loss of data, loss of learning progress, loss of profits or loss of goodwill, arising out of or related to the app, however caused;
• our total liability to you for all claims arising out of or related to the app in any twelve-month period is limited to the greater of CAD 50 and the amount you paid us for the app in those twelve months.

These limits do not apply to liability that cannot be limited by law, including liability for death or personal injury caused by negligence, for fraud, or for rights under consumer protection legislation that cannot be excluded.

11. Indemnity

If you are using the app for a business rather than as a consumer, you agree to defend and indemnify Acrylic Code Inc. against claims, losses and costs (including reasonable legal fees) arising from your breach of these Terms or your misuse of the app.

12. Termination

You can stop using the app at any time by uninstalling it; cancel any subscription through the store first if you do not want it to renew. We may suspend or terminate your access if you materially breach these Terms, if required by law or by a store, or if we discontinue the app, and in the last case we will act as described in section 6. Sections 4, 8, 9, 10, 11, 13 and 14 survive termination.

13. Governing law and disputes

These Terms are governed by the laws of the Province of Alberta and the federal laws of Canada that apply there, without regard to conflict-of-law rules. If you have a problem, contact us first at the address below and we will try to resolve it with you within 30 days. Any dispute that cannot be resolved that way will be brought in the courts of Alberta, and you and we agree to their jurisdiction. If you are a consumer, nothing in this section prevents you from bringing a claim in the courts of the province or territory where you live, or from using a consumer dispute process available to you by law.

14. Additional terms for the Apple App Store

If you obtained the app from the Apple App Store, the following also applies, as Apple requires:

• Acknowledgement. These Terms are between you and Acrylic Code Inc. only, not Apple. Acrylic Code Inc., not Apple, is solely responsible for the app and its content.
• Scope of licence. Your licence is limited to a non-transferable licence to use the app on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the app may be accessed and used by other accounts associated with you through Family Sharing or volume purchasing.
• Maintenance and support. Acrylic Code Inc. is solely responsible for providing any maintenance and support for the app. Apple has no obligation to provide any maintenance or support.
• Warranty. Acrylic Code Inc. 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 for the app to you; to the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the app, and any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to a warranty are the responsibility of Acrylic Code Inc.
• Product claims. Acrylic Code Inc., not Apple, is responsible for addressing any claims by you or any third party relating to the app or your possession or use of it, including product liability claims, claims that the app fails to conform to a legal or regulatory requirement, and claims under consumer protection, privacy or similar legislation.
• Intellectual property. If a third party claims the app or your possession and use of it infringes that party's intellectual property rights, Acrylic Code Inc., not Apple, is solely responsible for the investigation, defence, settlement and discharge of the claim.
• Legal compliance. You represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
• Developer contact. Questions, complaints and claims about the app go to Acrylic Code Inc. at the contact details in section 16.
• Third-party terms. You must comply with applicable third-party terms of agreement when using the app.
• Third-party beneficiary. Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms Apple has the right, and is deemed to have accepted the right, to enforce them against you as a third-party beneficiary.

15. General

Changes to these Terms. We may update these Terms. For material changes we will give notice in the app or on our website and revise the effective date above before the changes take effect; continued use after that date means you accept them. If you do not accept a change, stop using the app and cancel any subscription.

Entire agreement and severability. These Terms and the Privacy Policy are the whole agreement between you and us about the app. If any part is found unenforceable, the rest remains in effect.

No waiver and assignment. Our not enforcing a term is not a waiver of it. You may not assign these Terms; we may assign them to a successor of our business with notice to you.

Language. These Terms are written in English. Where the law requires a version in another language, the English version governs to the extent permitted.
