Privacy policy

Last updated: 24 September 2026.

Wiskundehulp is a static site. Calculators run in your browser. We do not store your sums on our own server.

Cookies and measurement

In this version we place no tracking cookies and no advertising network. There is no account. The light or dark theme choice is stored only locally in your browser (localStorage key wh-theme), not as a tracking cookie.

Videos (YouTube)

Some pages offer an explainer video. YouTube (youtube-nocookie.com) loads only after you click play. Before that click we do not load YouTube scripts or cookies. Once playback starts, YouTube/Google’s privacy terms apply.

Fonts

The site uses self-hosted fonts (Bricolage Grotesque, Inter and Caveat). They are not loaded from Google Fonts.

Hosting later

When the site goes live on wiskunde-hulp.com, the host may keep standard server logs (IP, time, requested page). Those logs are for operations and security, not to follow students. This policy will be updated if something material changes.

Contact

A privacy contact will appear on the contact page at launch.
