Overview

Ruler Real Online is a browser-based measurement tool that runs entirely on your device. We do not collect, store, or transmit any personal data.

Data Collection

We collect nothing. Ruler Real Online has no analytics, no tracking, no cookies, and no server-side processing. All functionality runs locally in your browser.

Local Storage

Your calibration settings (screen PPI, preferred unit, dark mode preference) are stored locally on your device using the browser’s localStorage API. This data never leaves your device and is only used to remember your preferences between visits.

You can clear this data at any time by clearing your browser’s site data for rulerrealonline.com.
