A rsync server (alpha release)
About this app
This app makes the shared storage of the device available via the Rsync protocol. Shared storage is what you can see in the "File Manager" app that usually comes with the device. This includes the 'DCIM' camera image folder as well as 'Downloads'.
When the "start" button is pressed and the device has Wifi connectivity, the app will open a rsync server on a random port with a random tag ("module" in rsync parlance). It will display all necessary details on how to connect to that server while it is running, e.g.
rsync://192.168.123.123:66671/abcdef/
Using a standard rsync client the server can then be interrogated and files moved back and forth, i.e. to and from the phone. The benefit is that the transfers can be driven from the client desktop, the keyboard and mouse interface of which making the process much more convenient.
Note: This app has not been widely tested and should therefore be considered alpha quality.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.github.ktsr42.rsyncserver is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 0.9.10 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Rsync Server first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Rsync Server, and a listing is removed when the evidence for it stops holding up.

Permissions Required
What each permission lets Rsync Server do. A highlighted one is worth a second look — not necessarily wrong, just worth asking whether this app needs it.
Previous Versions
The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
