No added advertising or audience analytics
This site adds no advertising or audience-measurement cookies, tracking pixels, external maps, embedded video or third-party chat. Photos and fonts are hosted with the website. An external service only loads if you follow its link.
Visual session preference
One functional preference may be stored in sessionStorage: ks_intro_seen. It prevents the short logo introduction from repeating during the same page session. It contains no name, email or form content, is not sent to the server and expires with the tab session.
Exercises and forms
Spreadsheet-demo values and pace selections stay in page memory. They disappear on reload. The form does not automatically save its contents in the browser; details are transmitted only when a submission is requested on the published site.
Hosting and changes
The provider may process technical logs for availability and security. Any new non-essential technology must be described and, where required, wait for prior consent with easy rejection and withdrawal. The tools currently added do not require an advertising-consent banner.
