Deleting your data Your collection, decks, match history, settings, and API keys are stored only on your device. You can erase all of it at any time from Settings → Privacy & Data → Delete All App Data, or by uninstalling the app. Neither deletes your account: the user ID, any email address you linked, any AI output reports you sent, and any AI usage recorded against it are held by Firebase. To delete your account and everything recorded against it, use Settings → Account → Delete Account in the app. If you no longer have the app installed, email cardadvantage@boundlessnotions.com from the address you linked and we will delete it for you. To request deletion of crash diagnostics associated with your app installation, email the same address with your device model and the approximate dates.
