XQ Private Ephemeral Email Encryption

XQ Message

Private email encryption with message revoke and disappearing messages.

Have private conversations that "disappear" in Outlook.

XQ works across existing email platforms, lets you set the email lifespan and 'unsend' or revoke emails.


'Unsend' emails by revoking access to encrypted emails by the recipients. Just click the REVOKE button and your email is no longer readable.


XQ emails "disappear".

By default, messages automatically expire after 3 days and then can't be decrypted. This way you won't have to worry about that credit card number you sent Joe's repair being in his email forever.


It's important that we make sending an XQ encrypted email simple and easy. XQ will let you encrypt and send a secure message in as little as 1 click! It doesn't get easier than that.


XQ offers 3 levels of security to match your needs: Instant, Personal and Lockdown! XQ uses an architecture using quantum random numbers that is more secure than existing email encryption solutions because super computers and quantum computers have a much harder time hacking it.


XQ won't read your emails and messages because we never have your data - neither will anybody else. The encrypted content stays within your existing service (like Gmail) and we provide the logic to encrypt and decrypt the messages.

Make your public conversations private. XQ is the easiest way to secure your email.

XQ is truly cross-platform. Easily send and receive one-click secure encrypted emails from Outlook to any other email app. XQ uses quantum safe encryption to edge secure your emails and give you a superior level of end-to-end data security.

XQ provides one-click secure encrypted emails for google mail. XQ is easy to use, works across existing email platforms and doesn’t allow your messages to be read by anyone except who you want.
