1. Privacy Commitment
We prioritize your privacy. All ruler measurements and calibrations are executed entirely within your browser. No personal data is collected.
2. Local Storage
We use browser localStorage solely to remember your unit preference (cm, mm, in), theme (light/dark), and calibrated screen PPI value.
3. Analytics & Cookies
We do not use invasive tracking cookies. Any technical telemetry is purely aggregated and anonymous to maintain server availability.
