Privacy policy

Written and maintained by The QuantityBench Team · Last reviewed

This site is static: there is no account system, no database, and no server that processes what you type into a calculator. The numbers you enter are calculated entirely in your browser and are never sent anywhere.

What is collected

This site itself does not set cookies beyond what Google Analytics and Google AdSense use (see below), and does not use any other tracking pixels. As with any website, the hosting provider (Cloudflare) processes standard connection information (such as IP address and request logs) as part of serving pages and preventing abuse — this is infrastructure-level logging, not something this site configures or accesses directly.

Analytics

This site uses Google Analytics (gtag.js) to understand aggregate traffic — which pages get visited, roughly how many people, and general navigation patterns. Google Analytics sets cookies (typically named _ga and _ga_*) to distinguish visitors between sessions. This site doesn't use the data to identify you personally, and doesn't combine it with any other information you might enter into a calculator, since calculator inputs are never sent anywhere in the first place.

You can opt out of Google Analytics tracking across all sites that use it with the Google Analytics Opt-out Browser Add-on, or by using a browser/extension that blocks third-party analytics scripts. If you're in the EEA, UK, or Switzerland, the consent prompt described below also governs analytics storage, not just advertising — declining it limits what Analytics collects too.

Advertising

This site uses Google AdSense to show ads. AdSense and its partners may use cookies and similar technologies (such as device identifiers) to serve ads, measure their performance, and personalize them based on your visits to this and other sites. This is Google's processing, not something this site itself collects or has access to.

If you're in the EEA, UK, or Switzerland, you'll see a consent prompt on your first visit letting you accept or reject personalized advertising — your choice is stored by Google's consent tooling, not by this site. Anyone can also review or manage ad personalization directly at myadcenter.google.com, and see how Google uses data from sites that use its services at policies.google.com/technologies/partner-sites .

Third-party links

Pages on this site may link to external resources (such as material suppliers or reference material). Those sites have their own privacy practices, which this policy does not cover.

Changes to this policy

If what this site collects changes — for example, when an analytics tool or ad network is added — this page will be updated to reflect that before the change goes live.
