4. Intellectual property

4.1 Ownership

The Site — including its original text, design, code, graphics, and selection and arrangement of content — is protected by copyright, trademark, and other intellectual-property laws. Other than the license in section 3.1, no rights are transferred to you.

4.2 Brand

"InchRuler.com" and the ruler logo are used to identify this Site. You may not use them in a way that suggests sponsorship, endorsement, or affiliation without written permission.

5. Accuracy and limitations of the tool

5.1 Factors that affect accuracy

The on-screen ruler's accuracy depends on, among other things:

• Your screen's physical pixel density.
• Operating-system display scaling.
• Browser zoom level.
• The care with which you performed calibration.
• Manufacturing tolerances of the screen itself.

5.2 No warranty of accuracy

The ruler is intended for general-purpose estimation. We do not warrant that measurements are accurate to any specific tolerance. Do not rely on the Site for engineering, medical, legal, safety-critical, or regulated measurement. See also the disclaimer.

5.3 Use at your own risk

You assume all responsibility for how you use measurements obtained from the Site. Where certified accuracy is needed, use a physical instrument that has been calibrated for the purpose.

6. Disclaimer of warranties

THE SITE IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, RELIABILITY, UNINTERRUPTED OPERATION, OR FREEDOM FROM VIRUSES OR HARMFUL CODE.

7. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL INCHRULER.COM OR ITS OPERATORS, CONTRIBUTORS, OR SERVICE PROVIDERS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO:

• Loss of profits, revenue, or data.
• Loss of use or business interruption.
• Cost of substitute services.
• Damages resulting from reliance on measurements obtained through the Site.
• Any other commercial or personal damages or losses.

This limitation applies regardless of the legal theory of liability and even if we have been advised of the possibility of such damages.

8. Indemnification

You agree to defend, indemnify, and hold harmless InchRuler.com and its operators from any claims, damages, losses, costs, or expenses (including reasonable legal fees) arising out of or connected to:

We may suspend or terminate your access to the Site at any time, without prior notice, for any reason, including breach of these Terms or suspected unlawful activity. Provisions of these Terms that by their nature are intended to survive termination (such as the sections on intellectual property, disclaimers, limitation of liability, indemnification, and governing law) will survive.

12. Governing law

These Terms are governed by the laws of [Jurisdiction], without regard to conflict-of-law rules. Any dispute arising out of or relating to these Terms will be subject to the exclusive jurisdiction of the competent courts of [Jurisdiction], unless applicable consumer-protection law grants you a different venue.

These Terms, together with our Privacy Policy, Cookie Policy, and Disclaimer, make up the entire agreement between you and us regarding the Site and supersede any prior agreements on the subject.

16. Waiver and assignment

Our failure to enforce a provision of these Terms is not a waiver of that provision. You may not assign your rights under these Terms without our written consent; we may assign ours in connection with a reorganization or transfer of the Site.
