Fundamental, Google was financed at its beginnings with CIA money., they want their ROI, getting data from Google customers. So other calendar syncronisations are a must. I used Google for my company i changed our policy, we use now www.pvy.swiss and privately I use proton.me many of the main IT providers from the USA are nothing but data robbers and stealers offering free services to indiscriminately scan private and business data. So I don´t use any longer software from Microsoft and Google, their are alternatives and they often are even better and cheaper.

Apple Calendar sync, export, anything, please.

A big +1 here, avoid Google and embrace modernity.

I echo Igor Couto's comment. This feature would be fantastic and a great selling point for future customers, users and collaborators.

People are becoming increasingly aware of privacy issues, and how companies like Facebook and Google are using their private data to turn their users into products they can sell. A growing number of companies are leaving Google's "free" services in favour of more privacy-conscious offerings - including Proton (https://proton.me), Fastmail (https://www.fastmail.com), and Apple's iCloud. Upbase could help the trend by supporting services other than Google, too...

or to display tasks as a calendar you could subscribe to? I'd like to be able to see them at least, I'm not sure if this would be different/easier to Achieve?
