Can I reactivate my account after deleting it?

If it's been less than 7 days since you scheduled the deletion, go to Your Data → Privacy & Settings → Delete Your Data, tap Cancel Deletion, and type KEEP MY ACCOUNT to confirm. Signing in by itself does not cancel the deletion.

After 7 days your account and data are permanently deleted and can't be restored. You can sign up again with the same email, but your previous points, profile, and history won't come back.
