Legal question about the use of cookies

we are using the Pydio Server Community Edition 8.2.0 in our own network and offer access to it from internet to external users.

To fulfill our legal obligations in the EU, i would like to know more details about Pydio’s Cooky policy in the server edition. Are they technical cookies? Is any user data from our server disclosed to you ( or Abstrium)?

As far as i can see, only one cooky (AjaXplorer) is set everytime i load the log-in page. What is it used for?

Thanks in advance.

Best regards,
