European calendar services
Shared calendars that sync without leaving Europe
Replaces: Google Calendar
A calendar service keeps your appointments in one place and syncs them to your phone, laptop and desktop client. Most offer shared calendars so colleagues or family members can see availability and add events, plus invitations and reminders. Support for the iCalendar standard, usually over CalDAV, is what lets a calendar you keep in one app show up correctly in another.
Your calendar is a detailed record of who you meet and when, which makes the hosting question a real one. Options such as Proton Calendar, Tuta Calendar and fruux are run by European companies, so the data sits under GDPR rather than under US disclosure law. Anyone looking for a European calendar service should also check that events can be exported as .ics files.
Proton Calendar
Encrypted calendar from Switzerland
Proton Calendar is a calendar service from the Swiss company Proton with a strong focus on privacy. It uses zero-knowledge encryption, which means the company cannot read the contents of your calendar even though the entries are stored on its servers.
