European alternatives to Google Calendar
German end-to-end encrypted calendar by Tutao GmbH, tightly integrated with Tuta Mail. All calendar data is encrypted on German servers using post-quantum TutaCrypt encryption. Standalone calendar app launched in 2024. Open source, no ads, no tracking.
Swiss end-to-end encrypted calendar by Proton AG. All event details (titles, descriptions, locations, attendees) are encrypted so even Proton cannot read them. ISO 27001 certified, independently audited annually by Securitum, own infrastructure in Switzerland and Germany.
