CryptPad is an #opensource collaborative editor (think: Google Docs/Drive) with a strong focus on #privacy. I have been using it for a while, and would like to recommend it to others as well!

You can try it here: https://cryptpad.fr/drive/

You can create and share text documents, sheets, presentations, code, kanban boards and more.

You can use it for free, but I recommend supporting them either by upgrading to a paid subscription, or by donating here: https://opencollective.com/cryptpad/
