Delete your account
In the app: account sheet → Delete account…. That erases your recipes, your shopping list, your stored pictures and the account itself. It cannot be undone and support cannot reverse it.
By mail: hello@getstaple.app, from the address on the account.
Deleting a single recipe removes it everywhere, and it is immediate. Cloud Logging entries expire on their own schedule (30 days) and are not deleted on request, because they are keyed to an account id that no longer resolves to anybody.
