Zero-Data Privacy Policy

1. Information We Do NOT Collect

Unlike many mobile applications that require camera access or accounts, Free Ring Sizer does not collect, log, sell, or transmit any personal measurement data:

• Ring Dimensions & Sizes: Ring diameters, circumferences, and calculated sizes remain exclusively within your local browser state.
• Biometric & Camera Data: We do not capture or record photos of your hands, fingers, or jewelry.
• Card & Financial Numbers: When you use a credit or debit card to calibrate screen scale, you are physically placing the plastic against your screen. No camera scanning, NFC reading, or card number input is ever requested or possible.
• Personal Identifiers: We do not require usernames, passwords, phone numbers, or mailing addresses to use any tool on this website.

2. Screen Calibration & Local Storage

When you adjust the screen calibration slider (or calibrate via credit card, coin, or ruler), the calibrated Device Pixel Ratio (DPR) is stored strictly in your browser's local session memory. You can clear this anytime by resetting the tool or closing your browser.

3. Cookies, Analytics & Log Files

To ensure the stability, uptime, and speed of Free Ring Sizer, we may use aggregate, privacy-friendly server logs or analytics (such as Cloudflare Web Analytics) that process:

• Anonymized IP addresses (masked or truncated)
• Browser type, operating system, and general device category (mobile vs desktop)
• Referring URLs and aggregated page view counts

We do not use invasive third-party cross-site advertising trackers or sell browsing data to data brokers.

4. Third-Party Links & Jewelry Retailers

Our guides, charts, or articles may contain links to external sites (such as jewelers, standard organizations, or educational resources). We have no control over and assume no responsibility for the content or privacy policies of third-party websites.

5. GDPR & CCPA/CPRA Rights

Because we do not store, process, or associate personally identifiable information with individual users, there is no personal data profile to inspect, correct, or delete. If you contact us via email, your correspondence is used solely to respond to your inquiry and is never repurposed for marketing.

6. Children's Privacy (COPPA Compliance)

Free Ring Sizer does not knowingly collect or solicit any personal information from children under the age of 13.

7. Policy Changes & Updates

We reserve the right to update this Privacy Policy from time to time to reflect changes in our tools or legal requirements. Any modifications will be posted on this page with an updated effective date.
