4. Health and safety disclaimer

Checkfit provides strength training programs for general fitness purposes. It is not medical advice. We are not licensed physicians, physical therapists, or registered dietitians.

6. Intellectual property

The Service, including all content, code, design, exercise illustrations, copy, and trademarks (including "Checkfit"), is owned by us or our licensors and is protected by intellectual property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for personal, non-commercial purposes, subject to these Terms.

8. Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate your account if you violate these Terms or if your use of the Service poses a risk to us or to other users. On termination, your right to use the Service ends; sections of these Terms that by their nature should survive will survive (including intellectual property, disclaimers, limitations of liability, and dispute resolution).

9. Disclaimers

The Service is provided "as is" and "as available," without warranties of any kind, express or implied, including 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 it will produce specific fitness, weight, or body composition results.

10. Limitation of liability

To the maximum extent permitted by law, in no event will we be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill, arising out of or in connection with your use of the Service. Our total liability for any claim arising out of or relating to these Terms or the Service will not exceed the greater of (a) the amount you paid us in the twelve months preceding the claim, or (b) one hundred US dollars ($100).

11. Indemnification

You agree to indemnify and hold harmless Checkfit / Moodzer, its affiliates, officers, and employees, from any claims, damages, or expenses (including reasonable attorneys' fees) arising out of your use of the Service, your violation of these Terms, or your violation of any third-party right.

12. Governing law and disputes

These Terms are governed by the laws of the State of California, without regard to its conflict-of-laws principles. Any dispute arising out of or relating to these Terms or the Service will be resolved through binding individual arbitration administered by JAMS, in Los Angeles County, California, except that either party may bring a claim in small claims court. You waive any right to a jury trial and to participate in a class action.

13. Changes to the Terms

We may update these Terms from time to time. Material changes will be communicated via email or in-app notice. Continued use of the Service after a change constitutes acceptance of the updated Terms.
