Best European Alternatives to Google Calendar (2026)
Google Calendar knows your appointments, who you meet with, and where you go — data that is connected to your ad profile and analysed across Google's entire ecosystem. This makes it a particularly sensitive piece of your digital life to hand to a US advertising company. European calendar apps give you the same scheduling features while keeping your schedule entirely private.
Replace Google Calendar with a private, EU-based productivity suite. Compare Collabora Online, CryptPad, Infomaniak kSuite and more. All GDPR-compliant, operated under EU privacy law.
