It has a terrible interface and the description lied about it being a material design. It also lacks export and sync.

does not conform to UNIX principles (let the application be one, but it will work well and cooperate with other functions and applications in the system); The interface is hideous. Nothing is anywhere, it's hard to figure out; It is not practical. Notion Calendar or Apple Calendar for example have a lot of common handy features that Etar doesn't have;

Proton Calendar vs Google Calendar Comments

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.

Looks very nice and clean, works well, has loads of features and is mostly free. My one complaint (and the reason I will be using calendar.online instead) is that there is no horizontal version for android tablets. I don't want to use my android tablet vertically.
