Description
Libre Contacts Backup is a FLOSS native Android app for private, local-first contact backups. No account, no cloud, no tracking — your contacts never leave your device unless you choose to move the backup file yourself.
Features:
* Lossless backup preserving the full Contact → RawContact → Data hierarchy, including contact groups
* Scheduled daily local backups at a time you choose, with no internet connection required
* Single-file LCB archives containing canonical JSON, VCF, CSV, and normalized exports
* Optional AES-256-GCM password-protected encryption (Android Keystore backed)
* Restore consolidates each source contact correctly, without merging different people who share a name
* Manual CSV, VCF, and Excel-compatible exports
* User-controlled retention for automatic backup archives
What’s new (2.3.1)
Fixed:
- F-Droid build now completes successfully by matching the Java toolchain version (21) available on the F-Droid build server, while keeping GitHub release builds on the same version to preserve reproducible builds
