Count me among those that use neither. I run a TrueNAS server at home and plan to install another off-site for redundancy.

Of course, I’ve been planning that off-site server for a couple years now. I’ve got to get on that before something happens.

I use Google Drive but it’s nothing important. Used it for school papers years ago. Now I use it to keep track of workouts and car maintenance.

Take a look at ProtonMail's offerings, they have a storage app. along with in-browser editing/collaboration tools, and their privacy policies are unmatched.
