Your data lives on your device
Every set is saved on your phone first, so Grain Gym works without a signal. An account is only for backup.
A backup is a snapshot of your full history at one moment. Go to Settings, then Backup & Restore. There are two kinds.
Restoring is a deliberate two-step action, and it replaces the local data the backup covers. Nothing runs on its own, so a backup is only as recent as the last one you made.
Settings has a Sync screen, but sync between devices isn't available yet, and the screen gives the reason. Until it is, your workouts stay on the phone where you logged them.
Use a backup. Use Grain Gym on more than one device has the steps.

Sync between devices isn't available yet. To move to a new phone, back up on the old one and restore on the new one.
Sign in with email, Google or Apple, sign out any time, and delete your account from Settings or from the website.
