1. Core Philosophy: 100% Offline & On-Device Privacy

At Synapse Technology and Research Centre, we believe that your personal files, documents, photos, audio, videos, and archives are your private property.

Summary Promise: File Manager: All in One is designed as a standalone, privacy-first mobile productivity tool. All file operations (browsing, searching, renaming, moving, copying, compressing, viewing, and encrypting) are performed entirely on your device. We do not operate remote servers that store, receive, read, or process your files.

2. Storage Permissions & Google Play Compliance

As an all-in-one file manager, the core and intended function of this application is full device storage management. To fulfill this purpose, the app requests standard Android storage permissions in full compliance with Google Play Developer Policies:

All Files Access (MANAGE_EXTERNAL_STORAGE) — Android 11+ (API 30+)

Declared strictly for the application's core purpose: allowing users to browse directories, copy, cut, move, rename, delete files, analyze storage usage, decompress archives (ZIP), and organize documents across internal storage and connected SD cards. This permission is used exclusively for on-device management at the explicit instruction of the user.

Media Permissions (READ_MEDIA_IMAGES, READ_MEDIA_VIDEO, READ_MEDIA_AUDIO)

Used on modern Android devices to categorize media into clean photo, video, and audio galleries, display thumbnails, and allow fast media playback without indexing non-media files unnecessarily.

Legacy Storage (READ_EXTERNAL_STORAGE / WRITE_EXTERNAL_STORAGE)

Provided for backwards compatibility on Android 10 (API 29) and earlier devices to enable standard file reading and saving.

Package Installer (REQUEST_INSTALL_PACKAGES)

Enables users to tap and install APK package files stored on their internal storage. The system always displays the standard Android confirmation dialog before installing any package.

3. Secure File Vault & Local Cryptography

File Manager: All in One includes an optional secure vault feature for locking private files behind a master PIN or password:

  • Local AES Encryption: Vault files are encrypted locally on the device using standard cryptographic algorithms.
  • Zero-Knowledge Architecture: Your PIN or password is stored solely on your local device (in secure shared preferences / keychain). We do not have access to your encryption keys and cannot decrypt your files remotely.
  • User Responsibility: Please keep a record of your vault password. Because we have no access to your device, lost passwords cannot be reset from a remote server.

4. Local Network & File Sharing

The app provides convenience features for sharing files:

  • System Share Sheet: When you tap "Share", files are handed off to Android's native share dialog. Files are only sent to the specific destination app you choose.
  • Direct Wi-Fi / Hotspot Transfer (Local LAN): If you use local Wi-Fi direct or QR transfer to send files between devices on the same local network, data travels directly peer-to-peer over your local network. No external cloud servers receive your transfer data.

5. Information We Do NOT Collect

We believe in total privacy by default. Specifically:

  • No Personal Accounts: You do not need to register, sign in, or provide your name, phone number, or email address.
  • No File Logging: We do not log file names, directory trees, document contents, photos, or file sizes to any analytics server.
  • No Location Tracking: The application does not collect or query GPS coordinates or network-derived geographic locations.
  • No Sale of Data: We never sell, lease, or monetize your data. We have zero business relationships with data brokers.

6. Third-Party Services & Crash Diagnostics

To maintain app stability and fix potential crashes across the diverse Android hardware ecosystem, the application may utilize standard Google Play services diagnostics (Firebase Crashlytics / Google Play Console):

  • Diagnostics reports are strictly non-personal and aggregated (e.g. Android OS version, device model, stack trace of an error).
  • No file contents, vault contents, or personal credentials are ever included in crash reports.

7. Children's Privacy

File Manager: All in One is a general-purpose productivity utility designed for all users. It does not contain age-inappropriate content and does not knowingly collect personal information from children under 13.
