There is no difference to Google when it comes to privacy. But I hope that was sarcasm, which seems so.

As you are lazy, creating an account for cryptpad (for example at the instance adminforge.de) you can pretty much use it exactly like Google Docs. Just that it is private :) And adminforge.de is quite big so it should not just „loose“ your files like Google. Of course keeping it local is better as there is the very very small probability that your chosen instance goes offline/closes.

For online collaboration use cryptpad. It is end-to-end encrypted and there are multiple instances where your files will be stored encrypted on their servers. You do not have to create an account and can share just using a link. For local editing I would say LibreOffice is the best.
