Privacy Policy

Right to Privacy is a universal human right. Letter as an email service affirms it.

Albeit, most people never had any doubts about privacy as a right. Mr Edward Snowden’s revelation has made it clear as to why we should worry about privacy of our digital data in transit and at rest on the servers.

Email is still the most preferred mode of personal and professional communication. Like most protocols on Internet everything was designed to work without additional layer of security. Email by default was not meant to be a secure mode of communication. It was meant as postcards or mail that could be easily read or intercepted.

Letter is built with free and open server software solutions for protecting your email’s integrity, security and privacy. Our focus is not just on strongest transport security with robust cipher suites but also data encryption while it sits on our disks on physical servers in secure data centres in different parts of Europe.

Additional features like per mailbox data encryption with individual user keys, disposable unlimited alias email addresses are deployed to prevent unauthorised access to significant email data and promote privacy among our beloved users.

We stand for your right to privacy. Letter will never share your data with third parties, unless we are obligated to do so by law.

We use free and open-source software solutions exclusively to entertain/promote transparency and open audits. Our whole email stack (Mailcow) and webmail software (Roundcube and SOGo) are freely licensed server software solutions. We choose to use it not for price as it is secondary but for the benefit it offers to our community as a whole.

Lastly, Letter aims to have a lucid and human readable privacy policy.
