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!

Ratings and reviews

If having all events/appointments one color is OK then the free version can work. And, startup time after closing the app' is interestingly sluggish, but left running it's up quick. To get color variety for types of events the fee is roughly 36€ a year, because color options only come with multiple calendars, which are past the pay-wall. Nope, not bothered enough by free options yet. Cheers.

This is the most secure email and calendar software that I've been able to find. they have super fast support that got me out of a big jam. they're paid. tiers are well worth the money. and if you get bored, look up how much of your personal information. Google is mining from you. they basically could clone you if they wanted to. they take feedback on their stuff. and are serious about their mission. highly recommend.

No notification for calendar entries. Have them enabled in app, in android, exluded from battery optimization. Not sure what to do else. App currently useless. Paid for tuta yearly sub as well. EDIT: contacted tuta support. A patch was released a few days back which helped with the notification issue.
