Google Docs is handy for editing your copy. However, Google Drive 1) uses your data to build their AI, and 2) is subject to lockdown based on their censorship.
Once again, if you don't want to shell out for Scrivener, I recommend Calmly Writer. It's a stripped-down markup editor, a little more sophisticated than Notepad. Save your work in a variety of file types. Free or $11. Do not rely on the cloud. #AmWriting
