Damn, I should have copyrighted Kudos to Kieran. And banned anyone from calling me a large Scotch.
I hope Kieran doesn't mind this fan advert for a free service. ProtonMail.ch, now Proton.ME to save 'leckie, has a new range of fairly impressive features on Proton Drive.
Proton Drive offers you the privacy of offline storage and the convenience and reliability of cloud storage.
All files are protected with end-to-end encryption
File metadata is also end-to-end encrypted, including file names, extensions, create/modify dates, etc.
Digital signatures allow you to check the authenticity and integrity of files
And like all Proton services, Proton Drive is open source, independently audited, and Swiss-based.
It's like Toblerone for your computer, CERN for your concerns.
