Legal
Terms & Conditions
By using Free Online Protractor you agree to these terms. They are written in plain language because obscurity helps no one.
Last updated Updated September 2026
Acceptance
By accessing or using freeprotractoronline.com (the “Site”) and the online protractor tool (the “Service”), you agree to these Terms & Conditions. If you do not agree, do not use the Service.
The Service
Free Online Protractor lets you measure angles and related geometry on images and PDFs in your browser. The Service is provided free of charge. There is no account registration.
Your content
Images and measurements stay on your device. You retain all rights in your files. We never receive them and claim no rights in your content. See ourPrivacy Policy for details.
Acceptable use
You agree not to:
- Use the Service in any way that violates applicable law
- Attempt to disrupt, overload, or reverse-engineer the Site for malicious purposes
- Represent the Service as a certified or calibrated measuring instrument
- Remove or obscure legal notices on the Site
Otherwise, you may use the tool for personal, educational, and commercial purposes at no cost and without attribution.
Measurement results
Readings are geometric measurements of an image, not certified measurements of a physical object. Their accuracy depends on your point placement, the image, and camera perspective — seeaccuracy and limits and thedisclaimer. You are responsible for deciding whether a reading is fit for your purpose, and for verifying anything consequential with a calibrated instrument.
The Service is not a medical device and must not be used for diagnosis or treatment decisions.
Disclaimer of warranties
The Service is provided “as is” and “as available” without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that measurements will meet your requirements.
Limitation of liability
To the fullest extent permitted by applicable law, Free Online Protractor and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill, arising from your use of the Service or reliance on its output.
This includes, without limitation, loss arising from work performed, materials cut, structural decisions, or any other action taken on the basis of a measurement taken here. Our total liability for any claim relating to the Service shall not exceed the amount you paid us (which is zero).
Intellectual property
The Site's design, code, and branding are protected by applicable intellectual property laws. You may not copy substantial portions of the Site for redistribution as a competing product without permission. Using the tool as intended is always permitted.
Availability and changes
We do not guarantee uptime. The Service may change, be updated, or be withdrawn at any time. Because it runs entirely in your browser, exporting a JSON workspace keeps a copy of your work independent of this Site.
We may update these Terms from time to time. Material changes will be reflected on this page with an updated date. Continued use after changes constitutes acceptance of the revised Terms.
Governing law
These Terms are governed by the laws applicable to the operator of the Site, without regard to conflict-of-law principles. If any provision is found unenforceable, the remaining provisions remain in effect.
