This is a simple app to show on a map (with leaflet and mapbox) the visits to this webpage.
In order not to use any tracking services (like Google Analytics) I'm parsing the logs of the web server (which contain information as the visitor's IP, the pages they visit and when they visited). In order to obtain the location of the users I am using ipinfo to generate a database with location information.
When showing the information of the database in this map nothing is uploaded anywhere, everything is browser-side javascript.
