Terms & Conditions

1. Acceptance of Terms

By accessing and using True Online Ruler (accessible via trueonlineruler.com), you accept and agree to be bound by the terms and provisions of this agreement. If you do not agree to these terms, please do not use this service.

2. Permitted Use

This website provides a free online ruler for personal and non-commercial measurement tasks. You may not:

• Attempt to decompile, reverse engineer, or extract the vector rendering calculations of this application.
• Automate screen scraping of our device profile database for commercial replication.
• Use the app inside iframe embeds without expressing attribution or prior written consent.

3. Disclaimer of Accuracy

While we strive to build an accurate online ruler tool, physical measuring accuracy is subject to hardware parameters:

We rely on device-pixel ratios (DPR) and client coordinate sizes reported by the browser. If a browser does not report device metrics correctly, or if you run custom OS-wide scale factors (zoom settings), the coordinates may shift. It is the user's responsibility to verify calibration accuracy against a known physical reference (such as a coin or credit card) before making critical measurements. We are not liable for errors resulting from incorrect calibration metrics.

4. Limitation of Liability

True Online Ruler is provided "as is" without warranty of any kind. Under no circumstances shall our team be liable for direct, indirect, incidental, or consequential damages resulting from the use or inability to use this screen-based measurement application.

5. Changes to Agreement

We reserve the right to modify these terms at any time. Your continued use of the website following any changes constitutes acceptance of the new terms.
