Doing so will permanently revoke your key and PIN code. This action cannot be undone unless you have backed your private key and data to a third party storage system, such as Dropbox. If you have, you must also delete your key there to ensure there are no copies available which can decrypt your data. This does not remove your downloaded data from your device. You must also uninstall Tenta Browser to remove your files downloaded to your Tenta Vault.
