Logging on my own (PC / Web server)

I’m very new to the QS-community, and I’m very curious about it.
But there is one thing I don’t like: I don’t want to put my data on the Server of some other than my own.

So is there a Webserver or Web tool I can install on my own server/PC. That helps me collecting/importing my data and analyze it giving me visualizations etc.?

What are your data sources, and what’s your level of tech expertise?
