* What caught my attention is that Criptext claims that it does not store your email on its server. According to FAQ page However, there are some exceptions.
For example, if you are logged in to the device but not turned on or connected to the Internet, emails will be stored on the Criptext server until your device can receive emails (powered on and connected to the Internet).

You can also use Criptext to send secure emails to non-Criptext email addresses. In this case, the message will be encrypted using the signal protocol, and the key will be encrypted using AES, and the recipient will receive a link that displays the encrypted message in the web browser. After opening, you will have 10 days to read the email before it expires.
As for the desktop application, it includes two-factor authentication, search using advanced filters, WYSIWYG editor for compose windows, all / unread view switching, tags, and automatic signature functions. It lacks the ability to use third-party email clients or multiple account support.
