2. What this policy covers

This Privacy Policy explains how Sirr: The Pass (the "App") handles your information. Because the App is fully offline with no network access, this policy is intentionally brief.

3. Information we collect

We collect nothing.

The App operates entirely on your device with no internet connection. It does not send any data to us or to any third party. Specifically:

No personal information is collected.
No usage analytics or behavior tracking of any kind.
No crash reports or diagnostic data are sent anywhere.
No advertising identifiers or device fingerprints are read.
No account registration or sign-in is required or possible.

4. Local storage (on-device only)

Passwords you choose to save are stored locally in your device's private app data storage using Android's DataStore (a secure, sandboxed storage mechanism). This data:

Is accessible only by the Sirr app on your device.
Is never transmitted, backed up to any server, or shared with any party.
Is permanently deleted when you uninstall the App.

5. Permissions

Sirr requires no system permissions. The App does not request access to your camera, microphone, location, contacts, phone, files, storage, Bluetooth, or any other system resource. It operates entirely within its own application sandbox.

6. Third-party services and SDKs

The App contains no third-party SDKs of any kind. There are no:

Analytics frameworks (e.g., Firebase Analytics, Mixpanel)
Crash reporting tools (e.g., Firebase Crashlytics, Sentry)
Advertising networks (e.g., AdMob, Meta Audience Network)
Authentication providers (e.g., Google Sign-In, Firebase Auth)
Cloud storage or sync services

7. Internet access

The App does not declare the INTERNET permission in its manifest and has no capability to make network requests. All functionality is 100% offline.

8. Data sharing and disclosure

We do not share, sell, rent, or disclose any data — because we do not collect any. There is no data to share.

9. Data retention and deletion

All data (your saved passwords and settings) exists only on your device. To delete it, simply uninstall the App. Android will remove all associated data automatically. There is no server-side data to request deletion of.

10. Children's privacy

The App is a utility tool designed for general audiences aged 13 and above. We do not knowingly collect personal information from anyone, including children. Because no data is collected, there is no risk of children's data being stored or transmitted.

11. Security

Because the App is fully offline and collects no data, the primary security boundary is your device itself. Your saved passwords are protected by Android's standard app sandboxing. We recommend using your device's screen lock to prevent unauthorized access.

12. Changes to this policy

If we update this Privacy Policy, we will post the updated version at https://privacy.saifullah.ai/sirr and update the effective date above. Significant changes will also be noted in the app's release notes on Google Play.
