Privacy Policy.
Your privacy is extremely important to us. RingSizeCalc.com is structured as a client-side utility. We do not gather, store, or transmit your device configuration or sizing measurements.
1. Data We Do Not Collect
When you use our online sizer tool (including Method 1 auto-detect, Method 2 screen diagonal overrides, or Method 3 reference coin alignment), all calculations are performed locally in your browser memory:
- We do not record screen width, height, or screen resolution.
- We do not collect user agent details for marketing purposes.
- We do not store the sizes of rings you match or select on our scale slider.
2. Use of LocalStorage
We use browser localStorage solely to save your theme preferences (dark mode or light mode). This configuration stays local to your browser profile and is not shared with any server.
3. Cookies and Analytics
We do not configure third-party advertising cookies or trackers. We may utilize anonymous server-side logs to monitor infrastructure health, which contain no personally identifying measurements or diagnostic parameters.
4. Third-Party Links
Our website may link to other sites or jewelry vendors. We are not responsible for the privacy practices of external web addresses. We advise reading their privacy policies when leaving our domain.
5. Contact Information
If you have questions regarding this privacy policy or our client-side calculations, feel free to contact us through our dedicated Contact Page.
