What is a way I can privately store files in cloud and sync between devices?

I right now use Google Drive to save and sync my Obsidian vault. I can make edits to my vault on my phone, desktop, or laptop and the changes will be backed up and sync to my other devices. I am worried about Google having access to those files containing that personal information, so are there any alternatives that are capable of the same thing?
