Hi!
This is a personal homepage with some online tools and technical information.
Privacy
Generally, none of the "tools" send data to the server, it's all JavaScript right in your browser.
Some pages require consent for a cookie and Google Ads, however (I'm trying to cover the hosting costs).
Other than that, only your anonymised IP address for each HTTP-request is stored on the server (to analyse site usage).
