Please read these Terms and Conditions ("Terms") carefully before using RealDigitalRuler ("the Service"). By accessing or using the Service, you agree to be bound by these Terms.
1. Use of the Service
RealDigitalRuler is provided free of charge for personal and professional use. You may use the Service to measure physical objects using your screen. No registration, login, or payment is required.
You agree not to:
- Use the Service for any unlawful purpose.
- Attempt to reverse-engineer, scrape, copy, or redistribute the source code or visual elements without prior written permission.
- Interfere with or disrupt the operation of the Service or the servers hosting it.
2. Accuracy Disclaimer
RealDigitalRuler is designed to provide highly accurate measurements when calibrated correctly. However, exact physical accuracy depends on various factors outside our control, including:
- Calibration Accuracy — Correct alignment using a physical standard like a credit card, screen specs, or direct PPI input.
- Screen Specifications — The physical aspect ratio, hardware resolution, and pixel shape of your display.
- Browser Settings — The zoom level (measurements assume 100% zoom with no custom layout scaling).
- Operating System Scaling — Native screen scaling options or font magnification settings.
Do not rely on RealDigitalRuler for safety-critical measurements — such as medical, engineering, aerospace, construction, or other professional applications where measurement errors could result in injury, financial damage, or structural failure. For precision and safety-critical work, always use certified physical measuring instruments.

The layout design, CSS style rules, logo, texts, article content, and visual assets of RealDigitalRuler are owned by us and protected under international copyright and intellectual property laws. You may not copy, modify, republish, or redistribute these assets without prior written consent.

5. Limitation of Liability
To the maximum extent permitted by applicable law, in no event shall we be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or use, incurred by you or any third party, whether in an action in contract or tort, arising from your access to, or use of, the Service.
