Privacy policy

Last updated 21 October 2026

CupGrams is a free reference website. We do not require accounts and we do not ask you to submit personal information. Calculators on this site run entirely in your browser; the numbers you type are not sent to us.

Hosting and logs

The site is served by Cloudflare Pages. Like any web host, Cloudflare processes technical data such as IP addresses and request logs to deliver and protect the site. See Cloudflare's privacy policy for details.

Advertising and cookies

We plan to show display advertising to keep the site free. At the moment no advertising or analytics scripts are loaded. When advertising is added (for example Google AdSense), third-party vendors including Google may use cookies to serve ads based on your prior visits to this and other websites. You will be able to opt out of personalised advertising at Google Ads Settings, and visitors in the EEA/UK will be asked for consent through a certified consent tool before any non-essential cookies are set. This page will be updated before any such script goes live.
