Privacy Policy

1. Information We Do Not Collect

Because Free Virtual Ruler is designed as an open, utility-first web application, we have engineered our software to function entirely without collecting personally identifiable information (PII). We do not require:

• Account registration, passwords, or profile credentials
• Credit card, bank account, or payment processing details
• Access to your camera, microphone, contacts, or file system
• Precise GPS or geographic location coordinates

2. How We Use Browser Local Storage

To provide a smooth user experience, FreeVirtualRuler.com utilizes your web browser's native localStorage feature. This allows your device to remember your settings between visits without sending anything to our servers:

• Calibration Setting: Stores your calibrated Pixels Per Inch (fvr_ppi) so you don't need to recalibrate on every visit.
• Measurement Unit: Remembers whether you prefer Inches, Centimeters, Millimeters, or Pixels (fvr_unit).
• Theme Mode: Stores whether you selected light or dark mode (fvr_theme).

This data remains 100% on your device and is never transmitted, synced, or shared externally. You can clear this data at any time by clearing your browser's site cookies and storage.

3. Technical Server Logging & Analytics

Like virtually all websites delivered via modern content delivery networks (CDNs), our servers automatically record basic technical access logs when you request web assets. These logs may include:

• Browser type and version (User-Agent)
• Referring web page and requested URLs
• Time and date of access
• Anonymized IP addresses used strictly for DDoS mitigation and routing efficiency

These operational logs are maintained strictly for network stability, uptime monitoring, and security protection. They are never tied to individual user identities.

4. Cookies and Third-Party Advertising

Free Virtual Ruler does not utilize third-party behavioral advertising cookies, affiliate tracking beacons, or cross-site tracking pixels. If external links are provided to standards organizations or resources, their respective privacy policies apply once you navigate away from our domain.

5. GDPR & CCPA Rights

Under regulations including the European Union General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA), individuals have rights regarding their personal data. Because we do not harvest, store, or sell any personal data, your privacy is preserved by architectural design. If you have questions regarding your data rights, you may contact our privacy desk.

6. Children's Privacy

Our service is a general-audience educational and practical utility suitable for users of all ages, including students. We do not knowingly collect personal information from children under 13 (or under 16 in certain jurisdictions) in compliance with the Children's Online Privacy Protection Act (COPPA).
