StackUp works without an account. If you signed in with Google to sync your training log between devices, you can delete that account and everything stored for it at any time.
Your account, the copy of your training log on our server and all your sign-in sessions are deleted right away. This cannot be undone. The log on the device you are using stays on that device and keeps working without an account; if you want a copy elsewhere, create a backup or an export in Settings → Data first.
If you no longer have StackUp installed, send an e-mail to feedback.stackup@undisputed-dev.com from the e-mail address of the Google account you signed in with, with the subject "Delete my StackUp account". We delete the account and its data within 30 days and confirm by reply.
