That means your data isn't accessible to anyone else - not even us. Only you have the key to access your messages and files on our secure servers. All the messages and attachments you receive in your Proton Mail mailbox are also stored with zero-access encryption, including messages from other email providers. When you send an email to other Proton Mail users or when you receive a message from another Proton Mail user, the message body and the attachments are fully and automatically encrypted at every step. The only way to transform the message into its original format is to use a unique encryption key. Using complex algorithms, a message is transformed into an illegible string of characters. Our data centers are located at highly secure sites that require biometric access.Įncryption is a process of converting messages or information in such a way that only authorized parties can read it.
