Proton Drive, Secure cloud storage and file sharing
proton.meProton Drive is now GA, from the same company as Proton Mail. End to end encrypted file storage. Disclaimer: part of the team that built it.
Will it eventually be possible to serve a static web site from it ? Fastmail offers this on its limited file storage service and honestly it is the only thing keeping me with them instead of fully moving on to Proton -- I don't need or want a full hosting solution.
It's not on the road map, which is quite busy right now, but I'll bring it up. We don't have document editing at all yet.
