The key to your privacy
Protect your online life with end-to-end encryption
Proton Mail protects the contents of all your messages with zero-access encryption, meaning no one can read them except you and your recipients. Messages you send to other Proton Mail accounts are always end-to-end encrypted, as are emails sent to non-Proton Mail accounts when you use Password-protected Emails.
With Proton Drive, everyone can use open-source and encrypted cloud storage. Proton Drive encrypts your files on your device before they are sent to the cloud so that no one can access them, not even Proton. Proton Drive also supports end-to-end encrypted file sharing, providing a secure, shareable link for your files.
Proton Calendar keeps your schedule secure by automatically protecting all your events and contacts with end-to-end encryption. When you invite someone to an event, their information is encrypted so no one can know their identity. Shared calendar invites are cryptographically verified so that your attendees can be sure it was you who invited them.
Proton Mail automatically encrypts and decrypts all your email attachments just as it encrypts and decrypts your messages. You can securely view your end-to-end encrypted email attachments in the Proton Mail app without downloading anything to your device. You can also send encrypted attachments to non-Proton Mail accounts by using the Password-protected Emails feature.
Using Proton’s end-to-end encrypted apps doesn’t just protect your privacy, it also protects the privacy of those you interact with. Proton Contacts automatically encrypts your contacts’ personal information, such as their phone number and address, as well as anything you write in your contacts’ notes field. Proton also verifies the integrity of your contacts’ data with digital signatures.

What others say about us
My favorite email service
I love my ProtonMail
You get what you pay for. In the case of big tech, if you pay nothing, you get used. I quit using Gmail and switched to @ProtonMail
Thanks Proton for keeping us all safe in the complicated internet universe.
