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
★★★★★flavio falgiani· Nov 29, 2025
Is the best option for people that love privacy very good and easy to use
★★★★★Gencho Draganov· May 4, 2026
I've been a user of both the calendar and mail apps and love them both. Functional, clean (which is what I admire) and most importantly private. I haven't found something I want out of my calendar app missing as of writing this. One minor preference - I liked the previous widget 😅 Both the small drawing that showed up when you had no events and the fact that events for the upcoming days showed up only when you scrolled down. Would love if there were options to choose between the two 😁

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.

Widget finally arrived but is next to useless!! Only shows one-day agenda (no other options, needs at least to show up to xxx days in the future as per most other calendars...), doesn't auto update & when (slowdown) manual update initiated never shows all events for the day, most times showing none at all (yes, all calendar boxes are checked). Also needs transparent / amoled background option. App itself is great but the (very) long awaited for widget is a complete disappointment so far.
★★☆☆☆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.
