Privacy policy
Effective October 11, 2026.
This policy explains what information ShelfCalc and its partners collect when you visit, and the choices you have.
Numbers you enter
All calculations happen in your browser. The numbers and item names you type into a calculator are not sent to us or stored anywhere.
Information collected automatically
Like most websites, our hosting provider keeps standard server logs, which can include your IP address, browser type, the page you requested and the time of the request. These logs are used to keep the site running and secure.
Advertising and cookies
This site uses Google AdSense to show ads. Google and other third-party vendors use cookies to serve ads based on your previous visits to this website and other websites. Google's advertising cookies let it and its partners show you ads based on your visits here and elsewhere on the internet.
You can opt out of personalized advertising from Google in Google's Ads Settings. You can opt out of some other vendors' use of cookies for personalized advertising at aboutads.info.

Visitors in some regions, including the European Economic Area and the UK, will be asked for consent before personalized ads are shown.
You can also block or delete cookies in your browser settings. The calculators work without them.
