Transparency Report & Warrant Canary for the secure email service Tutanota

2016-01-01 / Updated: 2020-09-09
This is Tutanota's transparency report and warrant canary information. While in Germany a gag order is legally not possible, we want to give you peace of mind by publishing a warrant canary.

The Tutanota Transparency Report is updated every six months. We only release individual mailboxes if we receive a valid German court order. All email content (subject, body, attachments) is end-to-end encrypted, and we cannot decrypt any of this data.

  • received requests for inventory data in 93 cases.

Warrant Canary

Tutanota has never received any National Security Letters or FISA court orders, and we have not been subject to any gag order by a FISA court. We have never placed any backdoors in our hardware or software and have not received any requests to do so.

We publish our web client, desktop clients and iOS & Android apps as open source so that everyone can verify that Tutanota does what we promise: Protect your encrypted emails to the maximum.



PS: The Transparency Report is updated every six months. The warrant canary is always up to date. If there was any request stated above, we would immediately take down the canary. However, such a request is not possible according to German law.
