Love this app, using on Windows 11 and Android.
Does anybody knows who is behind that "company"? No registration number, no address, no data protection (RODO) information and responsible person. Nothing. That's practically not possible in Europe and especially in NL. Strange, very strange.
Best independent desktop calendar app I've found. Works pretty good, no problems using with CalDav/Fruux. The app has extensive theming support, but unfortunately no option to follow system theme.
Basic functionality works but with Google, it has lot of problems. Invitations show historical meetings and recurring meetings etc... Some calendar events esp. recurring are show many times. There is possibility to select calendars to show from my Google accounts, but it shows some events multiple times. If you allow to show events in Windows lock screen it shows also cancelled events with text Cancelled... and historical one.. It should show my very next meeting there but no hope. I'm looking for an alternative event that I have purchased this one. I do not recommend. Sorry.
