Settings → Backup → Export my data. The file is handed directly to
you and does not pass through our server.
Settings → Account → Delete account. Your account and everything on
our server are deleted within 3 days, and you can cancel during that
window.
Open the paywall and tap Restore purchases. If that does not help,
write to us with the email address you used in the App Store.
Subscriptions are billed by Apple, so cancellation happens in your App
Store account settings, not in the app. Your subscription stays active
until the end of the period you already paid for.
