I don't believe Switzerland is a Nordic country, but +1 for Proton here. A lot of their newer products like Drive need a good amount of work, but Mail and VPN are working great for me.

To be fair, the Proton Foundation is a non-profit and is the majority shareholder of Proton.

That's fair. It has worked very well for me. Pass has been good too. I would probably use Calendar if they put more work into it, but it's still missing quite a few features. Like others have mentioned, Wallet is a bit of a head-scratcher, but if it could compete with Apple/Google Wallet, I would try it out for sure.

Do you ever use the VPN?
