Terms of Service

Last updated: May 10, 2026

1. Acceptance of Terms

By downloading, installing, or using Matn, you agree to these terms. If you do not agree, please do not use the app.

We may update these terms from time to time. Continued use of Matn after changes are published constitutes acceptance of the revised terms.

2. Description of the Service

Matn is a free app for reading, listening to, and memorising the foundational texts (mutun) of the Islamic sciences. It is built as a community and educational project. There are no ads, no in-app purchases, and no profit margin.

Features include line-by-line audio playback, memorisation practice with on-device speech recognition, progress tracking, favourites, and optional cloud sync across devices.

3. User Accounts and Authentication

You may use Matn without creating an account. Core features (reading, listening, and local memorisation tracking) work entirely offline.

To enable cloud sync, you can sign in using email and password, Google Sign-In, or Sign in with Apple. Account authentication is handled by Firebase Authentication.

You are responsible for keeping your sign-in credentials secure. If you believe your account has been compromised, contact us at hello@matn.dev.

4. User Data and Privacy

We take your privacy seriously. Our full Privacy Policy explains what data Matn collects, how it is stored, and your rights.

In brief: your memorisation progress, favourites, and settings are stored on your device. If you sign in, selected data is synced to Firebase Firestore. Speech recognition runs on your device by default. If you opt in to “Help improve Matn” in Settings, pseudonymised recordings and session metadata may be uploaded to help develop speech recognition. You can opt out and delete contributed data at any time. Analytics and crash reporting use Firebase Analytics and Crashlytics.

5. Intellectual Property

The classical Arabic texts included in Matn are in the public domain. You are free to read, copy, and share these texts.

The app itself (including its code, design, audio recordings, and branding) is proprietary. You may not copy, modify, distribute, or create derivative works from the app or its non-text assets without written permission.

6. Acceptable Use

When using Matn, you agree not to:

  • Scrape, crawl, or systematically extract data from the app or its servers
  • Reverse-engineer, decompile, or disassemble the app
  • Interfere with or disrupt the app’s infrastructure or other users’ access
  • Use the app for any unlawful purpose
  • Impersonate another person or misrepresent your identity
  • Circumvent any access controls or security measures

7. Termination

You may stop using Matn at any time. You can delete your account from within the app, which removes all associated data from our servers.

We may suspend or terminate your access if you violate these terms or use the app in a way that could harm other users or the service. We will try to give reasonable notice where possible, but reserve the right to act immediately if necessary.

8. Disclaimer of Warranties

Matn is provided “as is” and “as available” without warranties of any kind, whether express or implied. We do not guarantee that the app will be uninterrupted, error-free, or free of harmful components.

The speech recognition feature provides approximate feedback to aid memorisation practice. It is not a substitute for learning from a qualified teacher.

9. Limitation of Liability

To the fullest extent permitted by law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of Matn.

Matn is a free app with no revenue. Our total liability for any claim related to the service shall not exceed the amount you have paid us, which is zero.

10. Changes to These Terms

We may revise these terms at any time by updating this page. The “last updated” date at the top will reflect the most recent revision. For significant changes, we will make reasonable efforts to notify users through the app.

11. Governing Law and Jurisdiction

These terms are governed by and construed in accordance with the laws of England and Wales. Any disputes arising from or in connection with these terms shall be subject to the exclusive jurisdiction of the courts of England and Wales.
