Last updated: August 19, 2026

Your privacy at a glance

Local-first storage: Your data lives on your device first.

Sync only when signed in: We only sync data if you explicitly create an account.

Email-only account: No names, phone numbers, or addresses required.

No advertising: Zero profiling, zero trackers, zero ads.

1. Information We Collect

DengarBain may collect limited information that is necessary to provide its features and services.

When you create an account or sign in, DengarBain uses your email address for authentication. No additional personal information is required for account registration.

2. Learning and Progress Data

DengarBain allows you to track your learning progress for the forty Hadith. You may mark each Hadith as hafal, sedang, or belum.

Learning-related information may include your progress status, timestamps related to listening activity, and playback information such as A-B Loop points.

This information is designed to support your learning experience and is stored locally on your device using browser storage technology.

3. Local Storage

DengarBain uses local browser storage, including IndexedDB, to store learning progress and related application data on your device.

This allows core learning features to remain available without requiring a constant internet connection.

4. Account and Authentication

DengarBain provides registration and login using an email address.

Your email address is used to authenticate your account and support account-related functionality.

5. How We Use Information

Information collected by DengarBain is used only to provide, maintain, improve, and secure the application's features.

Learning data is used to provide features such as progress tracking, listening history, and learning-related functionality.

6. Data Synchronization

DengarBain may provide synchronization functionality between local device data and its backend services.

Where synchronization is enabled, limited learning-related data may be processed to support continuity of your learning experience across supported functionality.

7. Data Security

We take reasonable measures to protect information handled by DengarBain and to reduce the risk of unauthorized access, alteration, or disclosure.

However, no internet-connected service or electronic storage system can be guaranteed to be completely secure.

8. Third-Party Services

DengarBain uses a limited number of third-party services to operate and deliver the application.

These services may include Google Fonts for typography and GitHub for hosting and distributing the project's open-source source code.

These services may process information according to their own privacy policies and terms.

9. Deleting Your Learning Data

You can delete your local learning progress from the Settings page through the Danger Zone.

Use the Hapus Semua Progres action to reset your locally stored learning progress.

10. Children and Accessibility

DengarBain is designed as an educational application with a strong focus on accessibility, including support for children and users who are blind or visually impaired.

We aim to minimize the collection of personal information and provide an accessible learning experience.

11. Changes to This Privacy Policy

This Privacy Policy may be updated when DengarBain's features, services, or data practices change.

Any updated version will be made available through the application.
