Criteria
- Yes

Partial
No trackers or telemetry Weight 3 of 3
Are the website and apps free of third-party trackers, with any analytics anonymous and any telemetry off by default?

Securitum audited the web app, browser extensions and mobile apps. The full report is public but older than three years.
-
Partial

-
Partial
No stored mail Weight 3 of 3

-
No
Open protocols Weight 2 of 3
