One account for all of Gravl
You sign in with Apple, Google, or an email and password — and it's the same Gravl account across Gravl Macros and Gravl Workouts. Signing up with email includes a quick verification step (a code sent to your inbox) before the app opens up.
Signing out
Profile → Logout signs out this device only; other devices stay signed in. Normally your local data is cleared from the phone on the way out — that's a privacy feature, not a loss: everything lives in your account and returns on your next sign-in, once the device syncs.
The one exception is deliberate: if anything you logged is still waiting to upload, the app keeps the local copy instead of wiping it, so nothing can be lost between the last write and the last sync.
So you don't have to wait for a sync before signing out — that case is handled for you.
Forgot your password?
On the sign-in screen, tap Forgot password and enter your email — you'll get a reset link, choose a new password, and sign in with it. This same flow is also how you change a password you still remember: there's no separate change-password screen in the app, so request a reset email and set the new one.
If you signed up with Apple or Google, there's no Gravl password at all — access is managed by that provider.
