What Smart Protractor provides

Your responsibilities
You must have the rights to use any image you upload or paste, and you agree not to misuse the service for unlawful purposes.
Accuracy & limitations
The tool can display angles to 0.01°, but real-world accuracy depends on image quality, alignment, and perspective distortion. Use the tool for informational purposes and avoid relying on it for safety-critical, medical, or compliance-related decisions.
Privacy and data handling
Smart Protractor processes images locally in your browser and does not provide accounts or cloud storage. See the Privacy Policy for details.
