Privacy Policy

1. Overview

Ruler Size (“we”, “our”, “the site”) is a free, browser-based measurement tool available at rulersize.com. We are committed to protecting your privacy. This policy explains what information is handled when you use the site.

Short version: We do not collect, store, or share any personal data. There are no accounts, no analytics scripts, and no advertising trackers on this site.

2. Information we do not collect

We do not collect:

• Names, email addresses, or any contact information
• IP addresses or geolocation data
• Device identifiers or fingerprints sent to our servers
• Usage statistics, click events, or page-view analytics
• Payment or financial information (the site is entirely free)

3. Local storage

To remember your calibration settings between visits, the site writes a small number of keys to your browser's localStorage. These keys may include:

• ror-ppi — your calibrated pixels-per-inch value
• ror-theme — your preferred colour theme (light or dark)
• ror-lang — your selected interface language

This data never leaves your browser. It is not transmitted to any server and is not accessible to us. You can clear it at any time by clearing your browser's site data for rulersize.com.

4. Third-party services

We load web fonts from Google Fonts. When your browser fetches these fonts, Google may log the request in accordance with Google's Privacy Policy. No other third-party scripts, SDKs, or analytics services are loaded.

The site is hosted on a CDN. Standard access logs (IP, timestamp, URL, user-agent) may be retained by the hosting provider for security and abuse prevention purposes, subject to their own privacy policy. We do not access or process these logs for marketing purposes.

5. Cookies

We do not use cookies. Preferences are stored in localStorage as described in Section 3.

6. Children

Our site does not knowingly collect personal information from children under 13. Because we collect no personal information from anyone, no special handling is required. If you believe a child has submitted personal data through our site, please contact us and we will investigate promptly.

7. Changes to this policy

We may update this policy to reflect changes to the site. The “Last updated” date at the top of this page will reflect the most recent revision. Continued use of the site after changes constitutes acceptance of the updated policy.

8. Contact

Privacy-related questions or requests can be sent via our contact page. We aim to respond within 5 business days.
