Easiest in the app: Settings → Account → „Delete account". That deletes straight away and does not need this page.
If you no longer have the app, or want to do it here, you need a deletion code. The app shows it under Settings → Account. It is valid for 30 minutes.
What is on your device — recipes, lists, settings — is yours and is not touched from here. The app clears that itself under Settings → Reset.
The database is backed up regularly; the last 14 copies are kept. Your details may therefore sit in an older backup for a while, until it is overwritten in turn. Nothing is analysed from the backups — they exist only for recovery. Details in the Privacy policy.
If the app is already gone and you could not fetch a code, write to us; the contact address is in the Play Store listing and in the Privacy policy. We then delete by hand, once it is clear which account is meant.
