Data retention <br>We retain backups of deleted messages and documents for 45 days. This is for the purpose of restoring data in case of accidental deletion by users. After 45 days, data will be permanently deleted from all our systems.</li> <li>Account deletion <br>Should you close your account, all data will be permanently deleted 30 days after the legal expiration date (i.e. the Belgian law imposes 365 days after account closing). This means that your data will be PERMANENTLY deleted, as opposed to the practice of some major cloud companies which are unable to delete data.
