Delete your account
Deleting removes the account and everything our service holds about it: the email address, plan, sign-ins and connected devices.
Everything on your own Mac stays as it is. Masked documents and their restore keys live only there; they can still be restored.
A newsletter subscription under the same email address ends with the account. The link in each newsletter email ends it at any time.
To delete, sign in first. A second email then brings a deletion link that deletes the account for good.
