Description
Quantum-safe encrypted planner to schedule & manage your events & sync calendars privately.
Take your privacy to the next level with the secure Tuta Calendar app. This encrypted time-management tool is the most private way to organize your busy schedule – and it’s quick to navigate, comes with dark and light mode, plus, it’s perfectly integrated with the Tuta Mail app.
SECURE CALENDAR
• Quantum-safe encryption: End-to-end encrypted data exchange with all Tuta Calendar users and with users of other calendar apps (via optional password-protected event invites). • No ads, no tracking, and no data sharing: We protect your privacy. • Zero-knowledge architecture: Entire events, including event notifications, are encrypted and hidden from our servers. We do not know when your meetings are taking place, who they are with, or what they are about. • Based in Germany: All data is safeguarded by strict German data protection laws. • Fully GDPR-compliant
FULLY FEATURED
• Sync on all devices: Your Tuta planner syncs automatically on all devices and browsers. • Recurring events: Use daily, weekly, monthly, yearly or custom repetitions. • Multiple calendar views: Switch in one tap between agenda, daily, weekly, and monthly view. • Sync external calendars: Events will automatically sync if the owner adds or updates events or meetings on external calendars. Once subscribed, no action is needed. • Manage unlimited calendars (paid feature): You can toggle different calendars into view with a single press or leave all events visible for a complete overview. • Event reminders: Never miss a date. Tuta’s zero-knowledge reminders make sure you never miss an appointment. • Link calendar events to emails and contacts: Your Tuta Calendar is directly linked to your Tuta Mail account, so when creating events you can easily invite your contacts or send invites to others via email. • Offline support: Independent standalone app so you can check your schedule both online and offline!

Comments on Tuta: Secure Private Calendar for Android
★★★★★Johannes A· Nov 6, 2025
A clean and easy to use calendar app that syncs with my tuta account, the design style matches the mail app, and the home screen widget is really useful too! Thanks!
★★★★☆Maxim Ash· May 4, 2026
If you want to Google, but have qualms about Proton, Tuta is a great option. Having a separate Calendar app is useful, even though functionally it's not that different from the Mail app. If only the Duplicate function was working better, it would earn the full 5 stars from me. It's a great example where open-source succeeds - small apps done smartly, with only the required functionality. We don't need everything apps, TVM.

Is the best option for people that love privacy very good and easy to use
★★☆☆☆Ashley Redzko· Jun 18, 2025
I love Tuta mail, but this calendar widget leaves a lot to be desired. Some major pain points for me: - No option to subscribe to or manage outside calendars. - Unable to copy events to easily make a new one. - Reminders and notifications can sometimes fail to go off or go off on the wrong day or time if you update an event time. - No daily agenda view. - Clock widget for selecting time of events frequently breaks. I had to make the unfortunate choice to go back to Google calendar for now.
