Are there any cloud storage services that won't log your contents and sell you interest based ads with a document editing function?

I'm trying to move everything off of OneDrive and gdrive and decrease my dependence on mega ad corporations

Whatever you suggest I would like for the cloud storage to have a basic document editor so I can at least store and edit TXT files in the browser and not have to download or reupload it every time I need to make a change.

i don't think I need to store them in DOCX or RTF

After I move everything off …

ads basic can cloud cloud storage corporations document editing editor everything function interest log mega onedrive privacy sell services storage
