Privacy Policy - Gjenfinne

Effective date: 2026-10-30

1) Who we are

Gjenfinne is provided by Saifullah Ahad ("we", "us", "our"). Our website/portfolio is: https://saifullah.ai.

Location: Dhaka, Bangladesh

2) What this policy covers

Gjenfinne is a file recovery utility for Android that finds surviving files on external memory cards and USB flash drives, inspects their condition, and saves copies to your phone. This policy explains what the app handles and what it does not.

3) Information we collect

Gjenfinne does not collect, store, transmit, sell, or share personal data. The app has no user accounts, no profiles, no analytics SDKs, no advertising SDKs, no crash-reporting trackers, and no third-party telemetry.

Gjenfinne processes data locally on your device only. All scanning, carving, and recovery of files from connected external storage happens completely on the local processor.

Gjenfinne does not request the INTERNET permission. The app has no network access and cannot transmit data from your device.

4) Permissions and device access

Gjenfinne requests only the minimum access needed for file recovery:

USB Device Access: When an external USB drive or card reader is connected, Android prompts for permission to allow Gjenfinne to read the drive. Gjenfinne accesses the drive strictly in read-only mode to find surviving files. It never writes to or modifies the connected drive.
Saving Files: Gjenfinne uses the Android Storage Access Framework (system folder picker) to save recovered files to a folder you explicitly select. Gjenfinne refuses to save files back to the source drive being recovered.

5) Local settings and App Lock

The app allows you to set an optional 4-digit PIN lock. The PIN is hashed locally on your device using SHA-256 and stored in app-private storage. Key material is cleared from memory when the app leaves the foreground. The PIN is never transmitted off your device.

6) Third-party sharing

Because Gjenfinne collects no data and has no internet capability, no data is ever shared with, sold to, or accessible by any third party.

7) Children's privacy

Gjenfinne is a general file utility that does not collect any personal information from any user, including children.
