Welcome to Real Protractor Online. These Terms govern your use of the website and its tools (the online protractor, angle maker and ruler, quizzes, lessons, worksheet generator, leaderboard, and teacher dashboard). By using the site, you agree to these Terms. If you do not agree, please do not use the site.
1. The service
Real Protractor Online is a free educational website. All tools run in your web browser and are provided at no cost, with no account required. Progress such as XP and streaks is stored only in your own browser and is not a service we manage on your behalf.
2. Educational purpose
The site is intended to support learning and everyday measuring tasks. While the virtual protractor is rendered precisely, measurements depend on your screen, input device, and how carefully the tool is aligned. Do not rely on measurements from this site for engineering, construction, manufacturing, medical, or safety-critical purposes.
3. Acceptable use
- Do not attempt to disrupt, overload, or gain unauthorized access to the site or its hosting.
- Do not use automated means to scrape, mirror, or resell the site’s content or tools.
- Do not misrepresent the site as your own product or remove attribution from printed worksheets when redistributing them in bulk.
- Teachers and schools may print and share generated worksheets freely for educational use.
4. Your content
Images you upload for measuring are processed in your browser and never sent to us, so they remain yours. You are responsible for having the right to use any image you choose to measure. Content you print from the worksheet generator may be used for personal and classroom purposes.
5. Intellectual property
The site’s name, design, lessons, quiz questions, and code are the property of Real Protractor Online and are protected by copyright. You may not copy substantial parts of the site for publication elsewhere without permission.
6. No warranty
The site is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose, accuracy, or uninterrupted availability. We may change, suspend, or discontinue any part of the service at any time.
7. Limitation of liability
To the maximum extent permitted by law, Real Protractor Online and its operator shall not be liable for any indirect, incidental, or consequential damages arising from your use of — or inability to use — the site, including lost progress stored in your browser or a bad grade caused by a misread angle.
8. Third-party services
The site may link to third-party websites or, in the future, display third-party advertising. Those services are governed by their own terms and policies, and we are not responsible for their content or practices.
9. Changes to these Terms
We may update these Terms from time to time. Changes take effect when posted on this page with a new “Last updated” date. Continuing to use the site after changes are posted means you accept the revised Terms.
10. Governing law & contact
These Terms are governed by the applicable laws of the operator’s place of business, without regard to conflict-of-law rules. Questions about these Terms can be sent tosupport@realprotractoronline.com or through the Contact page.
