Calendar alternatives are worth considering when the incumbent gets expensive, restrictive, or invasive.

Tuta Calendar is encrypted end-to-end and ties into Tuta Mail. The free tier supports a single calendar; paid plans add sharing and external CalDAV invites.

Why consider the swap

If you currently rely on Google Calendar and want more control over data, lower long-term costs, or a freemium licensing model, Tutanota Calendar covers most of the same ground.

What you trade off

Most freemium alternatives require more setup than their commercial counterparts and may lag on polish, mobile apps, or ecosystem integrations. Check the project’s documentation for current feature parity with Google Calendar before committing.
