In short
Your Bro is an Android app for tasks, habits and notes, designed with a focus on privacy. The app is oriented toward storing data locally on the device and protects it with encryption. It does not use third-party analytics or trackers.
Important to understand: no app can guarantee absolute protection. The mechanisms below noticeably improve the security of personal data, but they don't replace the basic security of the device itself and the strength of your passwords.
Where data is stored
Tasks, habits, notes and attachments are stored locally on your device. A cloud account is not required by default for the app to work.
- The database is encrypted with SQLCipher.
- Media (attachments, voice and video notes) is encrypted with AES-256-GCM.
- Keys and secrets are stored via Android Keystore and EncryptedSharedPreferences.
- System Android backup is excluded for the app.
Access protection
App access can be protected with a PIN and biometrics. The FLAG_SECURE flag limits screenshots and previews of the app in the system's recent apps list.
Backup to Google Drive
Backup is a separate feature that is enabled only if you activate it yourself. Without your consent, a backup is not sent to the cloud.
- The backup is encrypted with a separate password (backup password) on the device — before upload.
- Google Drive is used as external storage for the encrypted backup file (the appDataFolder service folder).
- A backup password is needed to restore. Without it, the backup cannot be decrypted.
- The Google account by itself is not the decryption key.
Full restoration of all data and media on any device is not guaranteed. Some media uses device-bound keys, so moving it to another device may be risky. Keep the backup password safe — without it, restoration is impossible.
Speech recognition
Speech recognition works offline-first via Vosk and runs on the device. The language model is downloaded separately — that download requires the internet.
Analytics and trackers
The app has no third-party analytics or advertising trackers. The app was not built to collect and sell personal data.
Platform dependency
Some features depend on the Android system and Google services (for example, backup via Google Drive and biometrics). Those components are subject to the terms and policies of the respective providers, which Your Bro does not control.
