Criptext is an Open Source encrypted email service with a focus on security, privacy, and control over your email communications.
Criptext doesn't have access to your emails, and they do not store them on their servers, ensuring that you are in control of your emails. All your emails are locked with a unique key stored locally on your device, which means that only you and the intended recipient can read the emails you send.
The Criptext email service utilizes the Open Source Signal Protocol library, which protects your privacy and security throughout your entire Criptext experience.
Criptext is designed to be easy to use and to work as simple as any other email app â€” so much so, you'll forget how secure it is.
