Not really.
As a matter of fact, like I once used to when I was much younger, I realize I rely more and more on old tech (think pen and paper, printed books, physical medium) because they're reliable, I can fully own them, and I know they won't be spying on me and they will respect my privacy. Maybe it's just me getting old, or maybe I'm (finally) becoming cautious?
I use it and their free plan works fine but I've quickly upgraded to a paid tier. They claim zero knowledge E2EE, that's all I know. Free and paid plans offer the same level of privacy, as far as I know. But, if you plan on sharing files (I don't) make sure the free plan still offer that feature as I think I remember it was removed awhile ago (but I may be wrong).
I also think most our governments will sooner than later decide those kind of fully privacy-respecting cloud storage should not be accessed by mere users like ourselves (because 'think of the children' and the usual bullshit). So, I don't rely on it as my sole backup, I have another online backup solution (not cloud) and also keep a copy of all my files on a fully encrypted disk drive (two of them, as a matter of fact).
