Privacy Policy
GenChemCalc collects as little data as possible. The calculators run entirely in your browser.
Calculations
All calculations happen locally in your browser. The numbers you type into a calculator are not sent to our servers. If you use the Save feature, your saved calculations are stored only in your own browser's local storage on your device, and you can delete them at any time.
Analytics
We use Google Analytics 4 to understand which pages are used, in aggregate. This sets cookies and collects standard usage data such as pages viewed, approximate location and device type. We do not use this data to identify you personally.
Email newsletter
If you subscribe to receive the free reference card, your email address is stored by our email provider (Brevo) solely to send the download and occasional updates. You can unsubscribe at any time using the link in any email.
Affiliate links
Product links route through our /go/ redirects to Amazon. When you follow one, Amazon may set its own cookies under its own privacy policy. See our affiliate disclosure for details.
Your choices
You can block cookies in your browser, use the calculators without subscribing, and clear local storage to remove saved calculations. For questions about your data, contact [email protected].
