FAQ
Common questions
No. FOS Terminal works completely offline with your own SSH keys. No sign-up, no email, no cloud — unless you opt in to cloud sync.
Open Settings → SSH Keys → Import. You can import from a file, paste PEM content, or generate a new key directly on device. Keys are stored in the Android Keystore — locked to your device hardware.
Yes — Mosh requires the
mosh-server package on the remote server (available in most Linux package managers: apt install mosh). The SSH fallback works without it.On your device only, encrypted with AES-256-GCM. We never upload, access, or store your session data. Free plan keeps logs for 7 days; Pro keeps them indefinitely.
Free includes 41 features — SSH, Mosh, SFTP, multi-tab, port forwarding, jump hosts, all key types, and 7-day session logs. Pro adds 13 more: unlimited encrypted logs, live server monitoring, SFTP inline editor, cloud sync, biometric lock, snippets library, custom theme builder, Asciinema recording, and more.
Yes — 7 days free, no credit card required. Just download the app and start the trial from Settings.
Yes. €29.99 once, Pro features forever. All future features included. No annual fee, no subscription.
Yes. ProxyJump (bastion host) is fully supported and free. Configure in host settings → Advanced → Jump host. Unlimited hop chains supported.
Yes. Go to Hosts → Import → SSH Config. FOS Terminal parses your
~/.ssh/config including Host aliases, IdentityFile, ProxyJump, and User fields. All matching hosts are imported in one step.Yes, and it's optimised for them. On tablets, the host list and terminal run side-by-side. The SFTP browser uses a split-pane layout. On foldables (Galaxy Fold, Pixel Fold), the app adapts to both folded and unfolded states.
Private keys are never synced or uploaded. Cloud sync (Pro, opt-in) syncs host configurations, themes, and snippets only. Keys always stay on your device, secured by Android Keystore hardware.
