Privacy policy

Last updated 12 November 2026

The short version

We do not require an account, we do not ask for your email to show a rate, and the only data we collect is ordinary web analytics plus whatever our advertising partner collects.

What we collect

  • Server logs. Our host records IP address, user agent, requested URL and timestamp for security and abuse prevention. Retained for a short period.
  • Aggregate analytics. Page views and referrers, without cross-site profiling and without advertising identifiers.
  • Calculator inputs. Customs values and weights you type are processed in your browser. They are not transmitted to us and are not stored.

Advertising

This site is supported by advertising. When ads are enabled, Google and its partners may use cookies or similar technologies to serve ads based on your prior visits to this and other websites.

  • Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.
  • You may opt out of personalised advertising by visiting Google Ads Settings, or opt out of third-party vendors' use of cookies for personalised advertising at aboutads.info.
  • For visitors in the EEA, UK and Switzerland, consent is requested before non-essential cookies are set, and can be withdrawn at any time via the consent control on the page.

Your rights

Depending on where you live, you may have the right to access, correct, delete or port the personal data held about you, and to object to processing. Since we hold almost nothing identifiable, most requests resolve to a confirmation of that fact. Write to [email protected].

We do not sell personal information, and we do not knowingly collect data from anyone under 16.

Third parties

The site is hosted on Vercel and may use Google AdSense. Both act as independent processors or controllers for the limited data described above. Outbound links to hts.usitc.gov and other sites are governed by their own policies.

Changes

Material changes to this policy will be reflected in the date at the top of the page.
