Can I recover my buddies on another device or from a backup?

On iPhone and iPad, your Buddies encryption key is kept in iCloud Keychain, so your buddies follow you to your other devices signed in to the same Apple Account with iCloud Keychain on (Passwords, in iCloud settings), and come back after you reinstall WitnessWork. With sync on, Buddies starts by itself on your other devices once they sync: your buddies, your answers to invitations, the notifications you've read or cleared, and the nicknames and colors you chose show on each one, and each device gets Buddies notifications (choose which in Buddies Settings on that device). Without sync, open Buddies on the other device and pull down to refresh. Each device then shares the plans it has, so turn on sync to keep what your buddies see the same. Your buddies see one name for you from all your devices: the one you last changed in Profile on a device using Buddies. Buddies Settings shows it under How buddies see you. On Android, Google Play services keeps the key: it comes back when you reinstall WitnessWork on the same phone while Google backup is on (Settings → Google → Backup), and with a screen lock set it's also saved, end-to-end encrypted, in your Google backup, so it can return when you set up a new phone from that backup. Without a screen lock, the key stays on that phone. Android devices don't share one key the way iCloud Keychain does, so each Android device, and an iPhone and an Android phone, have their own Buddies connections. Regular WitnessWork backup files do not contain the encryption key. If the key is unavailable, or you used Delete My Buddies Data, reconnect with new invites. A device whose key went missing can still delete the Buddies data it kept, or sign in to another account; buddies of the old key keep that connection until they remove it. Keep your personal records backed up separately.
