Can I do the opposite of this app? (can I post data collected by my app to my own webpage automatically?)

Greetings. I am pasting below several blocks from @SteveJG 's National Weather Service app which finds the user's location and sends it to the NWS website in order to obtain the local weather service.

Can someone direct me to information about achieving this, or a paid app that will allow me to send the same data (Latitude and Longitude) to a page on my own website and notify me again when the app closes. Time, location and frequency of use are all that I am seeking and the time stamp is inherent in the connection. Thank you so much for any help or directions, and for your patience with me if this information is everywhere but I simply cannot find it.
