How Matomo browser tracking actually works, in six steps:

1. Good overview of How Matomo works: https://www.restack.io/docs/matomo-knowledge-what-is-matomo
2. Another good overview: https://developer.matomo.org/guides/how-piwik-works 
3. You deploy the Matomo stack on your computer or you start a Matomo Cloud instance.
4. When someone visits your website on phone or desktop, your HTML page loads, and a file called matomo.js loads into your visitor's browser, creating a _paq JS object,which stores properties and  methods
5. The JS listeners in the visitor's browser send some (dozens?) of reqs to your matomo.php endpoint, via HTTP, in the Tracking API whenever your visitor does something, starting with a pageview, If you use Matomo Cloud, this traffic goes from the visitor's browser to your private Cloud server in Frankfort Germany. If Matomo On Premise, this traffic goes from the visitor's browser to your own server in your hosting provider. Crucial feature of Matomo: it goes nowhere else. The data is immediately available as Visitors >> Visits log, and a few other places.
6. At your Matomo host, core:archive runs, enriching the raw data into human readable tables and reports, called aggregated data (report data)
7. You open a dashboard and see data
8. You send that data elsewhere:
   an email
   an alert
   a software like Power BI, etc
