    Proton Mail

    Proton AG

    Proton Mail is incorporated in Switzerland and all our servers are located in Switzerland. This means all user data is protected by strict Swiss privacy laws. All emails are secured automatically with end-to-end encryption. This means even we cannot decrypt and read your emails. As a result, your encrypted emails cannot be shared with third parties. No personal information is required to create your secure email account. By default, we do not keep any IP logs which can be linked to your anonymous email account. Your privacy comes first. We believe email privacy should be available to all. That's why our code is open source and basic Proton Mail accounts are always free.
