Looking to use a chat server - Questions

  1. I am looking for an application for my family & friends to use where they don’t need to be helping Google or others make money off their data. Would this fill that need?

  2. Install - I have a web server already, it’s located on-site and has a few domains registered for use with a few WordPress blogs running. Can I add Rocketchat to this server and continue using it as normal?

Many thinks for reading, and hope you all are having a happy, safe & healthy holidays.
