Email scanlystudio.support@proton.me and a person will answer. Please say which phone you are on and what you were doing when it went wrong. It usually saves a round trip.
Subscriptions are billed by Google Play, not by us, so they are cancelled in the Play Store rather than in the app: Google Play Store → your profile icon → Payments & subscriptions → Subscriptions → Christmas Countdown Widget → Cancel subscription. Cancelling stops the next renewal; you keep access until the period you have already paid for runs out.
If you bought the lifetime option, there is nothing to cancel: it is a one-time purchase and it does not renew.
Tap Restore on the plan screen. That asks Google Play for purchases made with the Google account currently signed in to the Play Store, so if you bought it with a different Google account, switch to that one first. If Restore still finds nothing, email us with the receipt Google sent you and we will sort it out.
Payments are processed by Google Play. Request a refund through Google Play (Google Play refund help) using the Google account you bought with. Tell us what went wrong anyway: it is how the app gets better.
Everything you set up lives only on the phone you set it up on. There is no account or cloud copy on our side, so the app cannot move it for you.
Your entries are stored on your phone and nowhere else, so deleting the app deletes them. See the privacy policy for the full picture.
