Terms of Service

Last updated: July 2026

Please read these Terms of Service ("Terms") carefully before using onlineruler.co ("the Service"). By accessing or using the Service, you agree to be bound by these Terms.

01

Use of the Service

OnlineRuler is provided free of charge for personal and professional use. You may use the Service to measure objects using your screen as a ruler. No registration or payment is required.

You agree not to:

  • Use the Service for any unlawful purpose
  • Attempt to reverse-engineer, scrape, or copy the Service for redistribution without permission
  • Interfere with or disrupt the servers or networks that host the Service
02

Accuracy Disclaimer

OnlineRuler is designed to provide accurate measurements when properly calibrated. However, accuracy depends on:

  • Correct calibration by the user
  • The physical characteristics of your specific screen
  • Browser zoom level (measurements assume 100% zoom)
  • Screen scaling settings in your operating system
Do not rely on OnlineRuler for safety-critical measurements — such as medical, engineering, or construction applications where measurement errors could cause harm. For precision work, use calibrated physical instruments.
03

Intellectual Property

The design, code, text, and visual assets of OnlineRuler are owned by us and protected by copyright law. You may not reproduce or redistribute them without prior written permission. The measurement functionality of the Service — using a screen as a ruler — is not claimed as proprietary; only our specific implementation is protected.

04

Disclaimer of Warranties

The Service is provided "as is" and "as available" without warranties of any kind, either express or implied. We do not warrant that the Service will be uninterrupted, error-free, or completely accurate for all devices and screens.

05

Limitation of Liability

To the fullest extent permitted by law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of your use of, or inability to use, the Service — even if we have been advised of the possibility of such damages.

06

Third-Party Links

The Service may contain links to third-party websites. These links are provided for convenience only. We have no control over third-party content and accept no responsibility for it.

07

Changes to These Terms

We reserve the right to modify these Terms at any time. The "Last updated" date at the top of this page will reflect the most recent revision. Your continued use of the Service after changes are posted constitutes your acceptance of the revised Terms.
