Privacy Policy

Last updated: September 26, 2026

1. Introduction

Welcome to ShoeSizeConversion.com ("we," "our," "us," or "the Service"). We operate an online shoe size conversion tool that lets you convert shoe sizes between international sizing systems — including US/CA, UK/IN, EU (EUR), Japan/MX (JP), and China (CN) — for adults (men and women), kids, and infants.

This Privacy Policy explains what information we collect (and what we don't), how we use it, and your rights as a visitor. We've written this policy to be transparent and easy to understand — because we believe privacy shouldn't require a law degree.

The short version: Every shoe size conversion you perform happens entirely inside your web browser. Your shoe sizes, foot measurements, and conversion results never leave your device. We don't track what you convert, we don't build profiles, and we don't sell data to anyone.

2. How Our Shoe Size Converter Works

Understanding how our tool processes data is the foundation of this policy. Here's exactly what happens when you use the Shoe Size Conversion tool:

  • 100% client-side processing — When you select a sizing system (e.g., US Men's size 10), choose a target system (e.g., EU), and view the conversion result, all calculations are performed by JavaScript running locally in your browser. No data is transmitted to our servers.
  • No server round-trips — The conversion tables and algorithms are loaded once when the page opens. After that, every conversion is instant and offline-capable.
  • No storage — We do not use localStorage, sessionStorage, IndexedDB, or any other browser storage mechanism to save your shoe sizes, foot length measurements, or conversion history.
  • No conversion logging — We do not log which sizes you look up, how often you convert, or which sizing systems you prefer.
  • Tab close = data gone — When you close the browser tab, any shoe size you entered into the converter is immediately and permanently erased from memory.

This design means that even we have no way to know what shoe sizes you've converted. Your sizing information stays entirely on your device.

3. Information We Do NOT Collect

To be explicitly clear, we do not collect, store, or process any of the following:

  • Your shoe sizes in any system (US, UK, EU, JP, CN, or any other)
  • Your foot length or width measurements (in cm or inches)
  • Your conversion history or conversion preferences
  • Your gender or age category selections (men's, women's, kids', infants')
  • User accounts, usernames, passwords, or login credentials (we don't have accounts)
  • Payment information (our service is completely free)
  • Precise geolocation data

We also do not use cookies for tracking, advertising, or profiling purposes.

4. Information We May Collect

While our core conversion tool collects zero personal data, certain parts of the website may involve minimal data handling:

4.1 Contact Form Submissions

If you reach out to us via the Contact page, we collect only the information you voluntarily submit:

  • Your name
  • Your email address
  • Your message content

Contact form submissions are processed through Web3Forms, a third-party form handling service. The data is transmitted directly from your browser to Web3Forms over an encrypted HTTPS connection and then forwarded to us via email. We use this information solely to respond to your inquiry. We do not add you to mailing lists, and we do not share your contact details with third parties.

4.2 Server Logs

Like virtually all websites, our hosting provider may automatically record basic technical information in server access logs:

  • IP address (which may be truncated or anonymized by the host)
  • Browser type and version (user agent string)
  • Pages requested and timestamps
  • Referring URL (the page that linked you to us)

These logs are used exclusively for security monitoring, abuse prevention, and diagnosing technical issues. They are not used to identify or profile individual visitors and are automatically deleted after a reasonable retention period (typically 30–90 days, depending on the hosting provider).

4.3 Language Preferences

Our website supports multiple languages through an internationalization (i18n) system. When you select a language, translation files are loaded from our server. We do not track or store your language preference beyond the current browser session.

5. Cookies & Local Storage

ShoeSizeConversion.com does not set any first-party cookies for tracking, advertising, or analytics purposes. We do not use localStorage or sessionStorage to persist any user data.

Third-party services embedded on our site (see Section 6) may set their own cookies according to their respective policies. For example, Google Fonts may use cookies as described in Google's Privacy Policy.

6. Third-Party Services

Our website relies on a small number of external services to function. Each is listed below with an explanation of what data it may access:

6.1 Google Fonts

We use Google Fonts to load the "Inter" typeface for consistent typography across devices. When the page loads, your browser connects to Google's font servers (fonts.googleapis.com and fonts.gstatic.com) to download the font files. Google may log this request, including your IP address. For details, see Google's Privacy Policy.

6.2 Web3Forms

Our contact form uses Web3Forms to process and deliver submissions. When you submit the contact form, your name, email, and message are sent directly to Web3Forms' API over HTTPS. For details, see Web3Forms' Privacy Policy.

6.3 External Links

Our blog posts, size charts, and informational pages may contain links to external websites (e.g., shoe brand sizing guides, footwear retailers). Clicking these links takes you to a third-party site governed by its own privacy policy. We are not responsible for the privacy practices of external websites.

7. How We Use Information

The limited information we may receive is used only for the following purposes:

  • Responding to inquiries — If you contact us, we use your name and email to reply to your message.
  • Maintaining website security — Server logs help us detect and prevent malicious activity such as DDoS attacks or unauthorized access attempts.
  • Improving the service — Aggregated, non-identifying traffic data (e.g., which pages are most visited) may be used to improve the shoe size converter, size charts, and educational content.

We do not use any collected information for advertising, marketing emails, user profiling, or sale to third parties.

8. Data Retention

  • Conversion data: Not retained — it exists only in your browser's memory during your session.
  • Contact form submissions: Retained only as long as necessary to respond to your inquiry, then deleted. You may request immediate deletion at any time.
  • Server logs: Automatically purged after 30–90 days by our hosting provider.

9. Children's Privacy

ShoeSizeConversion.com is a general-audience tool designed to help people of all ages find the right shoe size — including kids' and infants' sizing charts. However, the tool itself does not collect any personal information from any user, regardless of age.

We do not knowingly collect personal information from children under 13 (or under 16 in the European Economic Area). If you are a parent or guardian and believe your child has submitted personal information through our contact form, please contact us and we will promptly delete it.

10. Data Security

We implement appropriate technical and organizational measures to protect any information we handle:

  • Our website is served over HTTPS (TLS encryption), ensuring all data transmitted between your browser and our servers is encrypted in transit.
  • Contact form submissions are transmitted via encrypted API calls to Web3Forms.
  • Our core shoe size conversion tool operates entirely client-side, meaning there is no server-side database of user data that could be breached.

While no method of internet transmission is 100% secure, our privacy-by-design approach minimizes risk by simply not collecting data in the first place.

11. Your Rights

Depending on where you live, you may have specific legal rights regarding your personal information:

For EU/EEA Residents (GDPR)

  • Right to access any personal data we hold about you
  • Right to rectification of inaccurate data
  • Right to erasure ("right to be forgotten")
  • Right to restrict or object to processing
  • Right to data portability
  • Right to lodge a complaint with your local data protection authority

For California Residents (CCPA/CPRA)

  • Right to know what personal information is collected and how it is used
  • Right to delete personal information
  • Right to opt out of the sale or sharing of personal information
  • Right to non-discrimination for exercising your privacy rights

Disclosure: We do not sell, share, or use personal information for cross-context behavioral advertising. Therefore, there is no need to opt out of such practices.

For All Users

Since our shoe size converter collects zero personal data, most users will never need to exercise these rights. However, if you've contacted us via the contact form and wish to have your inquiry and associated data deleted, please reach out to us and we will comply promptly.

12. International Data Transfers

Our website may be hosted on servers located outside your country of residence. If you access ShoeSizeConversion.com from the EU/EEA, UK, or other jurisdictions with data transfer restrictions, please be aware that the limited data described in this policy (server logs, contact form submissions) may be processed in jurisdictions that may not offer the same level of data protection as your home country. By using our Service, you consent to such transfers.

13. Do Not Track Signals

Some browsers send a "Do Not Track" (DNT) signal with each HTTP request. Since we do not track individual users, profile visitors, or serve targeted advertisements, our website effectively honors DNT by default — regardless of whether the signal is sent.

14. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. When we do:

  • The revised policy will be posted on this page with an updated "Last updated" date.
  • For material changes, we may add a notice on our homepage.
  • Your continued use of ShoeSizeConversion.com after any changes constitutes your acceptance of the updated policy.

We encourage you to review this page periodically to stay informed about how we protect your privacy.
