+Fly.io can't process account or data deletion requests sent by email, including requests made under GDPR Article 17 or similar privacy laws. An email doesn't let us verify that the sender owns the account, so the self-service steps above are the only way to delete an account and the personal data attached to it. If you've lost access to your account, [reset your password](https://fly.io/app/password_resets/new) using the email address on the account.
