Our verdict on Tuta Calendar

Tuta Calendar is an end-to-end encrypted calendar for individuals, families, and organizations that want private schedule management. It supports event creation, reminders, recurring events, calendar sharing, email invitations, public calendar subscriptions through an ICS URL, and ICS imports. The service is available on web, Windows, macOS, Linux, iOS, and Android, with a mobile calendar widget and integration with Tuta Mail. Its privacy focus makes it a strong fit for people who want encrypted scheduling across devices rather than a broad calendar ecosystem.

The free plan includes one calendar, 1 GB of storage, and an encrypted calendar. The paid plan at 3.6 EUR per user per month, billed monthly, adds 20 GB of storage, unlimited calendars, calendar sharing, and event invitations. The highest paid plan costs 9.6 EUR per user per month, billed monthly, and includes 500 GB of storage alongside unlimited calendars, sharing, and invitations. Calendar is bundled with Tuta Mail rather than sold as a standalone calendar subscription, so the pricing structure suits users already considering Tuta's broader services.

Sharing is more detailed than a simple shared-calendar toggle: permissions can be read-only, read/write, or sharing management. External calendars can be subscribed to through ICS URLs and updated automatically in the mobile apps, while imported calendars do not continuously synchronize with their original service. That one-way approach and the limited integration set—Tuta Mail and Tuta Contacts—may not suit buyers who need extensive two-way connections with other calendar platforms. Choose Tuta Calendar for encrypted scheduling, private event sharing, and broad platform coverage; choose an alternative if external synchronization and ecosystem breadth are priorities.
