What we couldn't confirm3
- Whether the GPL-3.0 license covers the whole project, including the iOS app and desktop client, was not confirmed from the README.
- The README does not say whether Tuta offers calendar features, so the Google Calendar entry is unsupported.
- No closed-app descriptions were provided, so the replacement claims rely only on the community lists.
