YOUR CREDENTIALS STAY ON YOUR DEVICE

Access keys and secrets are stored in the Android Keystore through encrypted
system storage, never on any server of ours. S3Hub talks directly to the
provider you configure. There is no S3Hub account, no telemetry and no ads.

Device backups are disabled for the app's data, so a restore on another phone
cannot carry your connection details with it.

OPEN SOURCE
