Privacy Policy
Last updated: August 2026
ShoeSizeIt ("we," "us," "the site") provides a free shoe size calculator at shoesizeit.com. This policy explains what information the site collects, how it's used, and the choices you have. We've tried to write it in plain language rather than dense legal boilerplate.
1. Information stored in your browser
The calculator, your measurement history, saved profiles (e.g. names you give to track sizes for different family members), your rounding and unit preferences, and your light/dark theme choice are all stored using your browser's local storage — a standard web technology that keeps small pieces of data on your own device. This data:
- Never leaves your device or gets sent to our servers — we don't operate a database of user measurements.
- Is only accessible to this site, in this browser, on this device.
- Can be cleared at any time using the "Clear" button in the history panel, or by clearing your browser's site data.
- Is not a "cookie" in the traditional tracking sense, though it serves a related purpose (remembering your preferences between visits).
2. Information we do not collect
We do not require an account, do not ask for your name, email address, or any contact information to use the calculator, and do not knowingly collect personal information from children. Any "profile name" you enter to organize family members' sizes is stored only in your own browser's local storage as described above — it is never transmitted to us.
3. Third-party services
A few features on this site rely on third-party services that operate under their own privacy policies:
- QR code generation. If you choose to generate a QR code for a shared result, the shareable link (which encodes your foot length, category, and selected brand — not your name or any personal identifier) is sent to a third-party QR code generation service to render the image. This only happens if you actively choose to share and generate a QR code.
- Advertising. This site may display advertisements served by Google AdSense or similar ad networks. These networks may use cookies or similar technologies to serve ads based on your visits to this and other websites. You can learn more about how Google uses data at policies.google.com/technologies/partner-sites, and you can opt out of personalized advertising through Google Ads Settings or the Digital Advertising Alliance opt-out page.
- Analytics. We may use privacy-conscious analytics to understand aggregate traffic patterns (for example, which pages are visited and how often), without identifying individual visitors personally.
4. Cookies
This site itself does not set tracking cookies to identify you across visits. If advertising is enabled, our ad partners may set their own cookies as described above; where required by law (for example, under the EU/UK GDPR or ePrivacy rules), a consent mechanism will be presented before any non-essential cookies are set.
5. Your choices
- Clear your saved history and profiles at any time from the history panel or your browser settings.
- Use your browser's private/incognito mode to use the calculator without saving anything locally.
- Opt out of personalized advertising using the links in Section 3.
- Disable cookies entirely in your browser settings, understanding that some site features (like remembering your history) will then not work between visits.
6. Children's privacy
ShoeSizeIt is a general-audience reference tool, including a feature to help parents track children's shoe sizes over time. The site does not knowingly collect personal information from children, and any profile names used for tracking are stored only locally in the parent's or guardian's own browser.
7. Changes to this policy
We may update this policy from time to time as the site's features change. The "Last updated" date at the top of this page reflects the most recent revision.
