Your work stays on your device

Playground pages, notes, settings and finished tours are saved in this browser's own storage. They are not sent to a NETZ server, and clearing this site's data in your browser removes them.

Handwriting is recognised on your device. The recognition models are downloaded once and kept by the browser so they also work offline.

Analytics

NETZ uses Google Analytics and Vercel Analytics and Speed Insights to see which pages are used and how fast they load: for example pages visited, device and browser type, and approximate location derived from your IP address. Google Analytics uses cookies for this.

Ads

The landing page shows one ad from Google AdSense. Google may use cookies to show and measure ads, including ads based on your visits to this and other sites. You can read how Google uses this data at policies.google.com/technologies/ads and turn off personalised ads at adssettings.google.com.
