Privacy Policy

1. Zero Data Collection

At Zero-Slip Ring Sizer, your privacy is our absolute priority. Our web application is designed to function entirely "client-side." This means that all screen calibration, math, and ring size calculations happen directly within your web browser. We do not collect, transmit, or store any personal data.

2. Camera and Device Permissions

Our tool uses standard ISO/IEC 7810 credit card dimensions and manual screen diagonal inputs to calibrate your screen. We will never request access to your device's camera, microphone, or physical location.

3. Cookies and Tracking

The core Ring Sizer application does not use functional or tracking cookies. We may use basic, anonymized analytics (such as Google Analytics or server logs) strictly to understand aggregate website traffic (e.g., how many people visit the site daily). This data cannot be tied back to you individually.

4. Third-Party Links

Our website may contain links to external sites (such as Amazon for physical sizing tools). If you click a third-party link, you will be directed to that site. We strongly advise you to review the Privacy Policy of every site you visit, as we have no control over their practices.

5. Contact Us

If you have any questions or suggestions about our Privacy Policy, please feel free to contact us.
