Terms of Service
Last updated: June 24, 2026
These Terms of Service (“Terms”) govern your use of the Jabster boxing / fitness app and jabsterboxing.com (the “Service”), operated by Gravitas AI LLC (“Jabster”, “we”, “us”). By using the Service you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.
1. Health and fitness disclaimer (read this first)
Jabster provides general fitness and boxing-workout content for informational and entertainment purposes only. It is not medical advice and is not a substitute for professional medical guidance, diagnosis, or treatment.
- Consult a physician before beginning any exercise program, especially if you are pregnant, have an injury, or have any heart, blood-pressure, or other medical condition.
- Exercise carries inherent risks, including injury. You participate voluntarily and at your own risk. Stop and seek medical attention if you experience pain, dizziness, or discomfort.
- Use proper equipment, technique, and space. Jabster is not a medical device and does not diagnose, treat, or monitor any health condition.
- To the maximum extent permitted by law, Gravitas AI LLC is not liable for any injury or loss arising from your use of the workouts or content.
2. Eligibility
You must be at least 17 years old (or the age of majority in your jurisdiction) to use Jabster. The Service is not directed to children.
3. Your account
You are responsible for your account credentials and for activity under your account. Provide accurate information and keep it current. You may delete your account at any time (see section 10 and the Privacy Policy).
4. Subscriptions, billing and auto-renewal
Jabster offers auto-renewing subscriptions (e.g. monthly and yearly) and a one-time lifetime option that unlock premium features.
- Purchases are processed by Apple (App Store) or Google (Google Play) under their terms; we do not receive your payment card details.
- Subscriptions auto-renew at the then-current price unless cancelled at least 24 hours before the end of the current period.
- Manage or cancel your subscription in your Apple ID or Google Play account settings; deleting the app does not cancel a subscription.
- Prices, billing period, and renewal terms are shown at the point of purchase. Refunds are handled per Apple’s / Google’s policies.
5. License
We grant you a personal, non-exclusive, non-transferable, revocable license to use the Service for your own non-commercial fitness use, subject to these Terms.
6. Acceptable use
You agree not to: break the law; harass, abuse, threaten, or impersonate others; upload content that is unlawful, hateful, sexually explicit, violent, or infringing; choose a username that is offensive or impersonates someone; cheat or manipulate leaderboards, challenges, or points; reverse-engineer, scrape, or disrupt the Service; or circumvent payment or entitlement controls.
7. User-generated content
You retain ownership of content you submit (e.g. challenge photos / video, username). You grant us a worldwide, royalty-free license to host, store, display, and use that content to operate the Service (including showing your username / standing on public leaderboards). You are responsible for your content and confirm you have the rights to share it. We have zero tolerance for objectionable content and abusive behavior: we may remove content and suspend or terminate accounts. You can report or block other users and content in the app, and we act on reports (within 24 hours where appropriate).
8. Intellectual property
The Service, including workout content, video, audio cues, branding, the Jabster name, and the gorilla logo, is owned by Gravitas AI LLC or its licensors and is protected by IP laws. You may not copy, redistribute, or create derivative works except as allowed by these Terms.
9. Third-party services
The Service relies on third parties (Apple, Google, Supabase, Cloudflare, RevenueCat, PostHog). Your use may be subject to their terms; we are not responsible for third-party services.
10. Termination and account deletion
You may stop using the Service and delete your account at any time (in-app or via jabsterboxing.com/delete-account). We may suspend or terminate access for violations of these Terms or to protect the Service or other users.
11. Disclaimers
The Service is provided “as is” and “as available” without warranties of any kind, to the maximum extent permitted by law. We do not warrant that the Service will be uninterrupted, error-free, or that content is accurate or fit for a particular purpose.
12. Limitation of liability
To the maximum extent permitted by law, Gravitas AI LLC and its founders, officers, and agents will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or for personal injury arising from your use of the Service. Our total liability for any claim is limited to the greater of the amount you paid us in the 12 months before the claim or USD $50.
13. Indemnification
You agree to indemnify and hold harmless Gravitas AI LLC from claims arising out of your content, your use of the Service, or your breach of these Terms.
14. Governing law and disputes
These Terms are governed by the laws of the State of Florida, USA, without regard to conflict-of-laws rules. Disputes will be resolved in the courts located there, unless your local consumer law provides otherwise.
15. Changes
We may update these Terms; material changes will be posted here with a new “Last updated” date. Continued use after changes means you accept them.
