“These days, all Google and Apple and Big Tech talk about is privacy, so the best way to give our definition is to give the contrast. The way Google defines privacy is, “Nobody can exploit your data, except for us.” Our definition is cleaner, more simple, and more authentic: Nobody can exploit your data—period. We literally want to build things that give us access to as little data as possible. The use of end-to-end encryption and zero-access encryption allows that. Because fundamentally, we believe the best way to protect user data is to not have it in the first place.

I’ve used the Protonmail app for Android and the Protonmail website. There is a free tier with 1 GB of storage. For €120/year, you can get a VPN, file storage and an encrypted calendar. While you can get it slightly less expensively if you buy it in pieces from elsewhere, this is a very reasonable solution. Recommended.
