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

When ads are eventually shown, ad-serving partners may set their own cookies. When that changes, we will update this page and disclose exactly which partners are involved.
