## Description

FilesToNAS is an SMB backup app for Android. It backs up folders from your phone directly to your own NAS or SMB share — a Synology, QNAP, a home server, or any SMB2/3 share on your network. There is no cloud service in between, no account to create, and no data passing through anyone else&#39;s servers.<br><br>■ HOW IT WORKS<br><br>- Pick the folders you want backed up, point the app at your SMB share, and sync. Files go straight from your phone to your NAS over SMB2/3.<br>- Uploads are written to a temporary file first, then renamed atomically once complete. An interrupted transfer never leaves a half-written file at the destination.<br>- Backups are additive. New and changed files are uploaded; files already on your NAS are never deleted automatically.<br>- Sync state is tracked locally on your device, so the app knows what has already been transferred without relying on your NAS clock.<br><br>■ FREE<br><br>- One backup profile<br>- Manual sync<br><br>■ PRO — one-time purchase, no subscription<br><br>- Multiple backup profiles<br>- Automatic periodic sync over Wi-Fi<br>- NAS presets for Synology and QNAP<br><br>■ PRIVACY<br><br>- No ads. No advertising ID. No analytics. No third-party trackers.<br>- Your SMB credentials are stored locally on your device and used only to connect to the server you specify.<br>- Note: the SMB connection protects integrity through message signing, but file contents are not encrypted in transit. Use FilesToNAS on a network you trust.<br><br>Full privacy statement: https://filestonas.com/privacy/
