These terms apply to your use of anyonlineruler.com, provided under the name Any Online Ruler. By using the website, you agree to these terms. If you do not agree, do not use the service.
1. Purpose of the service
Any Online Ruler provides a browser-based ruler and information about everyday measurement. The tool is free to use and does not require an account. It is intended as a convenient reference, not as a certified measuring instrument or a substitute for professional advice.
2. Calibration and accuracy
You are responsible for calibrating the ruler and checking results against a reliable physical reference. Automatic detection and generic screen profiles are estimates. Device settings, browser zoom, screen changes, alignment and viewing angle can affect readings.
Do not rely solely on this tool for medical, engineering, manufacturing, safety-critical or other decisions that require verified precision. Place objects gently near the display and avoid anything that could scratch or damage it.
3. Acceptable use
You may use the website for lawful personal, educational and work-related measurements. Do not attempt to disrupt the service, bypass security controls, introduce malicious code, or use it in ways that infringe the rights of others. Ordinary access by search engines is not prohibited by this clause.
4. Content and third-party services
Website content and design may be protected by intellectual property rights. Access to the service does not transfer ownership of those materials. You remain free to use your own measurements. Third-party names and trademarks belong to their respective owners; references to devices or software do not imply endorsement or affiliation.
External links are provided for reference. We do not control the availability, content or practices of those services.
5. Availability and limitations
The service is provided on an “as available” basis. To the extent permitted by applicable law, we do not warrant uninterrupted access, compatibility with every device, or that measurements will meet a particular requirement.
To the extent permitted by applicable law, we are not responsible for losses resulting from inaccurate readings, interruption of the service or damage caused by placing objects against a screen. Nothing in these terms excludes liability or consumer rights that cannot lawfully be excluded or limited.
6. Privacy
The Privacy Policy explains browser-local calibration, saved preferences and other information handling. Review it before providing information through any contact channel.
7. Changes and contact
Features and these terms may change as the website develops. Revisions will be published on this page with an updated date. Questions about the service or these terms can be directed through the Contact Us page.
