Terms of Use

Last updated: August 29, 2026

These Terms of Use (the "Terms") form a binding agreement between you and Diego Rios Rojas ("we", "us") governing your use of the LingoTools mobile application (the "App"). Please read them carefully.

1. Acceptance

By downloading, installing, or using the App, you agree to be bound by these Terms and by our Privacy Policy. If you do not agree, do not use the App.

2. License to use the App

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control, for your own non-commercial language-learning use. This license is granted to you, the end user, and is subject to the Apple App Store's applicable licensed-application terms.

3. Subscriptions (auto-renewable)

The App offers an optional Premium subscription with auto-renewable terms, purchased through the Apple App Store. The following disclosures apply:

• Subscriptions are billed to your Apple ID account at confirmation of purchase.
• The subscription automatically renews for the same period at the same price unless you cancel it at least 24 hours before the end of the current period.
• Your account is charged for renewal within the 24 hours prior to the end of the current period, at the then-current price shown in the App.
• You can manage or cancel your subscription in your App Store account settings after purchase (Settings → your Apple ID → Subscriptions).
• The price, billing period (for example, monthly or annual), and any free-trial terms are displayed in the App at the point of purchase before you confirm.
• Any unused portion of a free trial, where offered, is forfeited when you purchase a subscription.

4. Acceptable use

You agree not to:

• use the App for any unlawful purpose or in violation of any applicable law;
• reverse-engineer, decompile, or attempt to extract source code, except where permitted by law;
• circumvent, disable, or interfere with usage limits, security, App Check, or other protective measures;
• abuse the AI, transcription, or shared-cache features (for example, automated bulk requests or attempts to inject harmful instructions);
• upload or submit content you do not have the right to use, or content that is illegal, infringing, or harmful.

5. User-provided content

You may import decks, audio, and other content, and you may enter text and audio (including microphone input for conversation practice). You are responsible for the content you provide and represent that you have the necessary rights to use it. You retain ownership of your content; you grant us a limited license to process it solely to provide the App's features (for example, generating transcripts or AI responses) as described in the Privacy Policy.

6. Intellectual property

The App, including its software, design, text, and branding, is owned by Diego Rios Rojas or its licensors and is protected by intellectual property laws. Except for the license granted above, no rights are transferred to you.

7. Third-party services and content

The App relies on and interoperates with third-party services (including Apple, Google/Firebase, RevenueCat, OpenRouter, and Groq) and may play or process third-party audio content such as podcasts and audiobooks. We do not control and are not responsible for third-party services or content, and your use of them may be subject to their own terms. AI-generated output may be inaccurate; you should not rely on it as professional advice.

8. Disclaimer of warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT TRANSCRIPTIONS OR AI OUTPUT WILL BE ACCURATE.

9. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOSS OF DATA, PROFITS, OR GOODWILL, ARISING FROM OR RELATED TO YOUR USE OF THE APP. OUR TOTAL LIABILITY FOR ANY CLAIM WILL NOT EXCEED THE AMOUNT YOU PAID US FOR THE APP IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

10. Termination

You may stop using the App at any time and may delete your account and data from within the App (Settings → Account → Delete account) or by removing the App. We may suspend or terminate your access if you violate these Terms or misuse the service. Provisions that by their nature should survive termination (including intellectual property, disclaimers, and limitation of liability) will survive.

11. Governing law

These Terms are governed by the laws of the Republic of Chile, without regard to its conflict-of-laws rules, except where mandatory consumer-protection laws of your place of residence apply.

12. Changes to these Terms

We may update these Terms from time to time. When we do, we will revise the "Last updated" date above. Continued use of the App after changes take effect constitutes acceptance of the updated Terms.
