Real Online Ruler ("we", "our", "the site") is a free browser-based measurement tool available at realruleronline.com. This policy explains what data we handle and how.

Data we do not collect

We do not collect, store, or transmit any personally identifiable information. There are no user accounts, no registration forms, and no login system. We do not run analytics that track individual users, and we do not sell or share data with third parties.

Data stored in your browser

The site stores a small amount of data in your browser's localStorage to remember your preferences between visits:

ruler-ppi — your calibrated pixels-per-inch value.
ruler-theme — your light or dark mode preference.
ruler-lang — your selected interface language.

This data never leaves your device. It is not sent to any server. You can clear it at any time by clearing your browser's site data for this domain.

Cookies

We do not set any cookies. The preferences listed above use localStorage, not cookies.

Third-party services

The site loads fonts from Google Fonts. Google may log the request as part of their standard CDN operation. See Google's privacy policy for details. No other third-party scripts, trackers, or ad networks are loaded.

Children's privacy

The site does not knowingly collect information from children under 13. Because we collect no personal data at all, the site is safe for general use.

Changes to this policy

If we make material changes to this policy we will update the "last updated" date at the top of this page. Continued use of the site after changes constitutes acceptance of the updated policy.
