Backup Companion

Backup Companion works with Android Backup for macOS to export device data that the ADB shell cannot query on its own. It is designed for the owner of the device and keeps the export in the app's private cache until the authorized Mac controller retrieves it.

The app can export, when you grant the relevant access:
- contacts, calendars, SMS/MMS, and call records;
- media indexes, shared-storage indexes, app inventory, and usage statistics;
- notification history, Bluetooth information, selected settings, and device metadata;
- portable VCF and ICS data where Android provides it.

Every access is optional and Android's Settings screens remain the source of truth. The app does not bypass Android's application sandbox, retrieve another app's private files, unlock Android Keystore material, or provide root access. Shizuku support is optional and requires a separate user-installed Shizuku service.

There is no account, advertising, analytics, cloud synchronization, or developer-operated backup server. Exports may contain highly sensitive data; review the permissions, protect the resulting backup, and delete temporary copies when finished.

Backup Companion is an independent companion for Android Backup for macOS and is not affiliated with Google or Shizuku.
