Data usage

When you use observability.date, various items of data are recorded by the server. These logs are retained for one week and then deleted. By inspecting the server logs, I can see the details of the observability charts that have been generated - the object name and coordinates, the location of the observer, the date and time. I use these data to improve the website - for example, I add new observatory locations when user-defined locations or geolocated positions suggest that they might be useful. Most data does not show up in the server logs as charts are generated by client-side javascript after the initial page load, but I occasionally track this too for site improvement purposes. No data is transferred to any third party at any time.
