Privacy

Last updated 19 October 2026.

The short version

Sizeproof has no accounts, no sign-up forms and sets no cookies of its own. We count clicks on shop links without knowing who clicked. Shops you visit from here have their own privacy policies.

What we collect

• Clicks on shop links. When you click through to a shop we record the time, which bag, which shop, the page you were on and your country as our host reports it. We don't record your IP address or anything that tells one visitor from another. We use these counts to see which bags people are interested in.
• Visit counts. We count page views with Cloudflare Web Analytics, which sets no cookies and doesn't follow you to other sites.

What stays in your browser

• Your answers in the finder are kept in the page address, so you can share a result. They aren't sent to us.
• Your choice of inches or centimetres and of light or dark mode is saved in your browser's local storage, and never leaves it.

Who else is involved

• Our host, Cloudflare, handles every request to this site, which includes seeing your IP address, to deliver pages and protect the site from attacks. See Cloudflare's privacy policy.
• Nothing else loads from other companies while you browse. Fonts, photos and data are served from sizeproof.app itself.
• Shops and affiliate networks. Some shop links are affiliate links. When you click one, the shop or network (for example Amazon, Impact, CJ or Awin) may set its own cookies to credit us for a purchase. Their privacy policies apply from then on.

Your rights

Because we don't store anything that identifies you, there's nothing of yours for us to look up, correct or delete. If you have a question about this policy, email [email protected].

Changes

If we change what we collect, we'll update this page and the date at the top.
