Calculator inputs
Dimensions, weights and quantities you enter are processed in your browser. They are not sent to or stored on our servers. Your light or dark theme choice is saved in your browser's local storage.
Analytics
We use Google Analytics 4 to understand which pages and tools are used, for example that a calculator was used or a summary was copied. It sets cookies and collects data such as pages viewed, approximate location, device and browser. We do not send the values you type. See how Google uses information from sites that use its services.
Advertising
We may show ads served by Google AdSense. Google and its partners use cookies to serve ads based on your visits to this and other websites. You can opt out of personalised advertising in Google Ads Settings or at aboutads.info. Visitors in the EEA, UK and Switzerland are asked for consent through a Google-certified consent message before personalised ads or analytics cookies are used.
Affiliate links
Some links to shipping software are affiliate links. If you sign up after clicking one, the partner may tell us a referral happened so we can be paid. We do not receive your account details.
Your rights
Depending on where you live (for example under GDPR or US state privacy laws) you may have rights to access, delete or object to processing of personal data. Because we do not hold calculator data or accounts, most requests concern Google's cookies, which you can manage in your browser and in the settings above. For anything else, email hello@billedweight.com.
Changes
We will update this page if what we collect changes, and change the date above.
