Privacy, in plain language

Your calculations stay in your browser

The calculators run on your device. We do not send your entered values to an application database, require accounts, or add advertising and analytics scripts to the website.

If you choose Share result, the generated link contains your input values in its address. Anyone you give that link to can see those values. Opening a shared link also sends that address to the hosting service as part of the web request. Avoid sharing sensitive information through calculator links.

Hosting and technical requests

ChemistryCalc is hosted with Cloudflare Pages. Like other web hosts, Cloudflare processes technical information needed to deliver and protect the website, such as request addresses and network information. Its processing is covered by Cloudflare’s privacy policy.

We do not set advertising cookies. Browser features such as copied results and your browsing history remain under your device and browser settings.

Links to other websites

Sources and further-reading links lead to other websites with their own privacy practices. We do not control their content or data handling. This notice describes the ChemistryCalc website as launched on October 28, 2026.
