Terms of Use

Effective date: November 8, 2026.

These Terms govern your use of TUFF 90, a US adult fitness-tracking service. By using the service, you agree to these Terms and acknowledge our Privacy Policy. If you do not agree, do not use the service. The legal operator's name and mailing address must be confirmed before public launch.

1. Eligibility

You must be at least 18 and legally able to agree to these Terms. You are responsible for deciding with your healthcare professional whether exercise or nutrition changes are appropriate for you. TUFF 90 is not an emergency service.

2. Your account

Provide accurate account information, protect your credentials and do not share an account or impersonate someone else. You are responsible for activity under your account except as applicable law provides otherwise. Report unauthorized use promptly. You can stop using the service, export your records or delete your account in Settings.

3. Crews, cheers and acceptable use

Use crews, invitations and preset cheers respectfully. Do not harass, threaten, discriminate, send unwanted repeated invitations, upload unlawful material, reveal another person's private information, impersonate others, bypass membership limits or security controls, scrape private records, or disrupt the service. Invite only people you have a legitimate reason to contact; do not use invitations for unsolicited bulk outreach. Sharing progress is optional and other members' privacy choices must be respected.

4. No medical advice

TUFF 90 provides general fitness information and is not medical advice. Consult a healthcare professional before starting any exercise program. Stop exercising and seek help if you feel pain, dizziness, or unusual shortness of breath.

Consult a doctor before starting exercise or changing nutrition, especially if you have a medical condition, take medication, are pregnant, have recently had surgery or have a history of an eating disorder. Stop if you feel pain or dizziness. Seek urgent medical help for concerning symptoms. Content, hydration estimates and daily targets do not diagnose, treat or prevent disease, replace individual professional advice, or guarantee results. Optional calorie targets are entered by you, not prescribed by TUFF 90. See the Health notice.

5. Exercise risks

Exercise and nutrition changes carry risks, including injury, illness and aggravation of existing conditions. Choose activities, equipment and intensity suited to your abilities and follow professional guidance. You voluntarily choose whether and how to participate and understand these risks. Progress goals are never a reason to ignore symptoms. Nothing in these Terms waives rights or liabilities that cannot legally be waived.

6. Your content and our materials

You retain ownership of entries you provide. You grant TUFF 90 a limited right to store, process and display those entries only as needed to operate the service consistent with the Privacy Policy. You must have permission to provide any information you submit. Our branding, software and provided workout content remain owned by us or our licensors. You may use the service and its sharing tools for personal, lawful purposes; no ownership of our materials transfers to you.

7. Availability and changes

Features may change, be interrupted or be discontinued. We do not guarantee uninterrupted access, error-free records or a particular fitness outcome. Keep an export of records important to you. Third-party sign-in, hosting and email services may have their own terms and outages. We may update these Terms and communicate material changes as required by law; if you do not agree to updated Terms, stop using the service.

8. Suspension and termination

We may restrict or terminate access for violations, security concerns or legal requirements, with notice where appropriate and required. You may delete your account at any time. Deletion removes active app data and membership but cannot recall emails or images already shared. Lawful retention obligations and terms intended to survive termination still apply. Contact us if you believe access was restricted in error.

9. Disclaimers and limitation of liability

To the extent permitted by law, the service is provided “as is” and “as available,” without warranties of merchantability, fitness for a particular purpose or noninfringement. To the extent permitted by law, TUFF 90 is not liable for indirect, incidental, special or consequential damages arising from use or inability to use the service. These limitations do not exclude liability for fraud, willful misconduct, gross negligence, personal injury where exclusion is unlawful, or any nonwaivable consumer rights. No monetary liability cap is set in this first draft.

10. Governing law and disputes

Governing law: [State and legal operator to be confirmed after legal review]. Courts and venue: [To be confirmed after legal review]. Applicable mandatory consumer protections remain in effect. This draft does not impose arbitration or a class-action waiver. Contact us first if you want to discuss a concern informally.

11. General terms and contact

If a provision is unenforceable, the remaining provisions apply to the extent permitted by law. Failure to enforce a provision does not waive it. These Terms do not limit rights granted by applicable law. Contact: hello@tuff90.com.
