Share to NAS

Share to NAS is private file sharing without the public cloud.

Share a file in Android, choose Share to NAS, and your phone sends it over encrypted FTPS directly to your own FRITZ!Box NAS. The app then creates a share link you can copy, send, or show as a QR code.

Your FRITZ!Box becomes your personal cloud-free file drop: no developer servers, no ads, no trackers, and no third-party cloud storage.

Why Share to NAS?
• Cloud-free: files are stored on your own FRITZ!NAS, not with an app provider
• Private: credentials stay encrypted on your Android device
• Direct: encrypted FTPS upload to your FRITZ!Box
• Practical: Android Share menu, copy links, send links, or show QR codes
• Multiple files: upload separately or bundle them into one ZIP
• Mobile-ready: MyFRITZ! address and external HTTPS/FTPS ports can be detected at home
• Controlled: share links with configurable validity and access limit
• Secure: HTTPS, FTPS, Android Keystore, optional biometric/device-unlock protection
• FRITZ!Box-friendly: SHA-256 certificate pinning for self-signed certificates
• Tidy: expired or used app-created shares can be removed automatically

Private instead of public cloud
Share to NAS does not operate a backend server. Selected files and FRITZ!Box credentials are not sent to the developer. The app talks only to the FRITZ!Box you configure. It is not a central cloud or P2P network; it is a direct private route from your Android device to your own NAS.

Requirements
You need a FRITZ!Box with NAS access enabled, a FRITZ!Box user with read/write NAS permission, HTTPS, and the FTP/FTPS NAS service. For access away from home, MyFRITZ! and secure Internet FTPS access must be configured on the FRITZ!Box.
