History

  • Syncthing began as a cross‑platform replacement for proprietary sync tools; the Android wrapper exposes core features with mobile‑friendly options.

Why use it

  • Keep data local to your devices; versioning; selective folder sync; no central server.

Safe use

  • Use unique device IDs; approve devices explicitly; set untrusted folder permissions carefully; avoid syncing sensitive folders over metered networks unless via VPN.

Limits

  • Requires both peers online at the same time or via relays; battery optimization may pause background sync.
