You can delete your LegendPass account and its data at any time, from inside the app or by email. Here is exactly what happens when you do.
Email support@gammapass.com from the address on the account with the subject “Account deletion request”. We verify ownership of the email address and then delete the account within 30 days, and confirm by email when it is done.
You do not have to close the account to remove data from it. Deleting something in the app deletes it from our servers as well.
