Privacy and browser controls

What stays in your browser

Search and fictional lab calculations run in your browser. The calculations do not contact a remote service. This tab saves at most 20 positions to help you return to a page, open section or selected link. Entries older than two hours are ignored. Closing the tab normally clears them; browser session restoration may keep them.

Links you share

Page addresses, saved return links and browser history can contain search terms, filters or lab settings. Sharing a link shares those choices. The part after a question mark also reaches our host when you open the page. Avoid personal or confidential details. Clear the fields or restart a lab to reset its choices.

Visitor statistics

Analytics is disabled. No analytics scripts, tracking pixels or visitor statistics are sent.

You can exclude this browser from any future pageview statistics. This choice applies only to this browser and website, until you remove it or clear the site’s data. Clearing saved return positions does not remove it. If the choice cannot be saved, statistics stay off.

Analytics is disabled for this site. JavaScript can show your saved choice.

Hosting and external links

This site is hosted by Vercel. Vercel processes ordinary delivery and security information, including IP addresses and requested URLs. It may retain this information for operational, security, contractual and legal purposes under its privacy notice; retention depends on those purposes. This site does not add its own server-side visitor logs or analytics. Hosting privacy notice ↗.

Browser exclusion does not stop hosting requests. Source links lead to other websites with their own privacy policies. Our images, fonts and scripts do not load from external providers.

Advertising

Advertising is disabled. No advertising scripts or ad requests are loaded, and no space is reserved for ads. Future ads would require site approval, updated privacy information and tested consent controls before loading. There is currently no live advertising consent service.
