Said about Proton Calendar as an alternative

Deivedux ProtonCalendar may not be as feature-rich as Google Calendar, but their main focus is protecting user data with end-to-end encryption. The free plan is enough for basic calendar functionality, but paid subscriptions give extra benefits for supporting their business model, as that's their only source of income.
