Move your hosts, keys, saved commands, and settings to a new phone, encrypted on your device with a passphrase only you hold, then stored in your own Google Drive. The passphrase is the only key, and it never leaves your phone.
Your hosts, SSH keys, saved commands, and settings, encrypted on the phone with your passphrase before anything leaves it. Google only ever stores data it can't read, in TermHub's own private folder in your Drive, hidden from your other files and every other app.
Open Settings › Backup & restore, sign in with Google, and set a passphrase. Turn on auto-backup and every change is encrypted and synced quietly in the background.

Install TermHub, open Backup & restore, sign into the same Google account, and enter your passphrase. Choose Merge to add the backup's hosts to what's on the device, or Replace to make the device match the backup exactly.
TermHub is live on Google Play. Install it and connect to your first host in a couple of minutes.
