Do not send payment card details or Google / Apple passwords. For a charge you do not recognize, use Google Play or App Store support as well.
Super is billed by the store, not inside a GubbiGo profile. Cancel auto-renewal here:
After you cancel, Super stays on until the end of the period you already paid for. Free lessons keep working after that.
Sign in to the same Google or Apple account you used to subscribe, install GubbiGo, and use Restore purchases in the app (when you are online). There is no GubbiGo login.
Progress is stored on that device. Clearing app storage, uninstalling, or switching phones without backing up the device can remove it. That does not cancel Super; restore Super as above, then continue from free or unlocked lessons on the new install.
Uninstalling GubbiGo deletes local progress. To ask us to delete RevenueCat customer data we can control, email developer@xlang.in and say it is a deletion request. See the Privacy Policy for what we hold and what stays with Google, Apple, Expo, or Cloudflare.
