What we collect

Chemkit does not require an account and does not run backend calculations on your inputs — every calculator runs entirely in your browser, and nothing you type into a calculator is transmitted anywhere.

We use standard privacy-respecting web analytics (Google Analytics 4) to see aggregate traffic patterns: which tools are used, from which countries, on which devices. Analytics is loaded via a deferred script that runs only after the page is interactive and does not block rendering. You can block it with any standard content blocker.

What we do not collect

• We do not collect personal information.
• We do not sell or share any data.
• We do not fingerprint your browser.
• We do not read your clipboard.

Cookies

Analytics may set a small number of cookies to distinguish sessions. No advertising or tracking cookies are set by us.

Third parties

No advertising partners are currently active on Chemkit. When ads are enabled, this page will list every partner and the categories of data they receive.
