Terms and Conditions

1. Agreement and Acceptance

By accessing or using Scale Online Ruler (https://scaleonlineruler.com), you agree to be bound by these Terms. If you disagree with any part of the terms, you may not access or use the application.

2. Permitted Use and License

We grant you a personal, non-exclusive, non-transferable, revocable license to access and use Scale Online Ruler for:

• Personal Use: Measuring household objects, craft materials, stationery, hardware, and small goods.
• Educational Use: Classroom instruction, physics demonstrations, geometric exercises, and school projects.
• Professional & Commercial Reference: Screen design layout checks, graphic dimension validation, UI inspection, and 3D printing sizing.

3. Calibration & Accuracy Advisory

Scale Online Ruler is engineered with mathematical precision algorithms. However, physical accuracy depends strictly upon correct screen calibration performed by the user:

• User Calibration Responsibility: Users must calibrate their screen using standard physical references (such as an ISO credit/bank card or explicit diagonal screen size) to achieve 1:1 true-to-scale accuracy.
• Display Zooming Notice: Browser zoom (e.g., zooming to 125% or 80%) alters on-screen dimensions. Users should keep their browser zoom level at 100% (default) or recalibrate when zoom is modified.
• Not for Critical Sizing: Scale Online Ruler is a digital estimation utility and should not be used as the sole measuring instrument for mission-critical architectural engineering, aerospace manufacturing, surgery, or legal surveying where certified calibrated micrometers are required.
