Privacy Policy

Last updated: June 2026.

What We Collect

AtticWorth has no accounts, no sign-ups and no comment forms. We do not collect names, emails or payment information. The tools on this site (serial lookups, estimators, dating tools) run entirely in your browser — what you type into them is never transmitted to us or stored.

Analytics

We use Umami, a privacy-respecting analytics tool, to count visits and see which pages are useful. It does not use cookies, does not fingerprint you, and stores no personally identifiable information. IP addresses are not retained.

Affiliate Links

Some outbound links to marketplaces (such as eBay) may be or become affiliate links, meaning we may earn a commission if you make a purchase — at no extra cost to you. These links are marked sponsored in our HTML, and affiliate status never influences our value estimates: the numbers come from the data pipeline, not the business model.

Third-Party Sites

Links to eBay, auction houses, Wikimedia Commons and other external sites are governed by those sites' own privacy policies.
