Welcome to Online Ruler (onlinelineyka.com). We are committed to protecting your privacy and being fully transparent about how data is handled.
Online Ruler operates entirely on the client side in your web browser. We do not require accounts, logins, or personal details to use any measurement features.
2. Information We Do NOT Collect
When using our screen ruler, calibration tools, or articles, we do NOT collect:

- Payment or card details: Credit card calibration is purely optical on your screen; no card numbers or photos are ever captured or transmitted.
- Biometric, audio, or video stream data.
- Precise GPS location coordinates.
3. Browser Local Storage (localStorage)
We use your browser’s localStorage solely to save your local calibration settings (PPI, chosen unit, selected theme):
- Calibration state (PPI value and method).
- Unit preference (cm, mm, or inches).
- Color theme (dark or light mode).
4. Anonymous Usage Analytics
We may use privacy-compliant web analytics (Google Analytics) to measure aggregated, anonymized page views, device types, and browser versions to help improve performance.
IP addresses are anonymized and never combined with personal data.
