This is a small hobbyist site, with no commercial nature whatsoever. As such there is only the minimal data collection necessary for monitoring the web server and diagnosing any issues with it.
This site stores logs of web activity in a format very close to Common Log Format, using Apache's "combined CustomLog' format specifically.
As an example, here's the elided log excerpt from when I just access this page during writing it:
A.B.C.D - - [09/Oct/2019:14:24:07 +0100] "GET /docs/privacy-policy.html HTTP/1.1" 200 4715 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:69.0) Gecko/20100101 Firefox/69.0"
These logs are kept for a variable amount of time, with the current rotation setup being based on how big they grow and a fixed number of generations. If they don't exceed the maximum size then they are rotated weekly for 52 generations so as to yield a year's worth of logs. As I type in October 2019 I still have logs from October 2018.
There are also separate error logs kept, to help in diagnosing any issues. Again these currently go back to October 2018.
The web logs could be processed to give an overview of site traffic, but this is not done at the current time.
No external analytics are used.
Some tools on this site might utilise Cookies and/or Local Storage for the purpose of storing user settings. This usage is purely functional and necessary for the individual tools with no cross-tracking performed. None of this data will ever be passed to anyone else unless explicitly noted on the pages in question, and after requesting permission to do so from the user.
