google drive, getting away

So here is the issue, I use Google Drive because I am a writer who does a lot of writing. And I thought the cloud was a reliable way to store my writing, however now Google is looking through it's to train their ai. And I'm worried about that, especially since I have written a lot of questionable content, porn and the like. What if Google Now arbitrarily decides that I'm not using Google Drive properly and bans me from the Google, that's not good. What should I do and what alternatives can I use? Will these Alternatives still be around in like 10 years?
