Question I just thought of as I opened up a document. Where do you write and store your writing?

I used to use Google Drive/Docs up until a few months ago. I liked the ability to be able to access my work on any device, because a lot of my time is spent lying down, so I tend to write on my phone quite a bit. I started getting really wary of their AI usage though, so I've since switched to Ellipsus. It's a free site that has a firm standing against AI, and you don't have to pay anything to use it. There's no limit on storage either! (Good for me, because there are a lot of documents.) I could use Microsoft Word but it doesn't have the same organization/feel for me as sites like Google Docs or Ellipsus. I'm a guy who needs folders. Lots and lots of folders.

Of course, I have all my important writing saved to my computer's hard drive. I don't want to lose anything, after all!

So, yeah, I'm just curious now. What do you use to write?
