Is there a good dark net version of google docs available? So docs can be stored and managed online in a secure way while not being tied to you

I need to store some documents online and the documents need to be able to be referenced by different members of my crew. the different members also need to be able to add to the documents so everyone can manage it together. Basically I need a darknet version of google docs that is secure and also can't be tied to me so it needs to be anonymized with tor. Is anything like this available?

use your own NAS with .onion routing. I think its the best way to have your drive "out of weird data centers"

I didnt hear somebody created onion domain i.e website with such possibilities, but you can create it for yourself.

To create a document collaboration platform accessible only through Tor, you'll need to set up a Tor hidden service and then deploy a collaborative document application behind it. This involves running a Tor client, configuring a hidden service, and choosing a suitable document collaboration software. application should be also configured to use specified port for the hidden service. so, you can google which collaborating service work with tor and is it free or you must pay for this or that number of collaborators.

Is there a good guide available for doing that?

Thanks for the suggestion. Do you know if there's a good guide available somewhere on how to do this?
