The short version

  • IndexFit and Indy give fitness information, not medical advice. Train within your limits.
  • Indy is AI and can be wrong. Check its plans and calorie estimates before you rely on them.
  • Pro renews until you cancel it in your Apple account settings. Apple handles payments and refunds.
  • Play fair in leagues and competitions, and be decent to people in chats.

These Terms of Service ("Terms") cover your use of the IndexFit app for iPhone and Apple Watch and its related services (the "Service"). By downloading or using IndexFit, you agree to these Terms. If you don't agree, please don't use the Service.

1. Eligibility and accounts

You must be at least 13 years old (or the minimum age of digital consent where you live) to use IndexFit. You're responsible for what happens under your account and for keeping your Apple sign-in secure. Please give accurate information and keep it up to date.

2. License

Subject to these Terms, we give you a personal, limited, non-exclusive, non-transferable, revocable license to download and use IndexFit on Apple devices you own or control, for your own non-commercial use, in line with the App Store Terms of Service and the Usage Rules in Apple's Media Services Terms and Conditions.

3. Subscriptions and purchases

Free and Pro

Logging workouts is free for your first 3 months. Leagues, your history and Apple Health sync stay free after that, within the limits shown in the app. IndexFit Pro is a paid subscription, billed monthly or yearly, that adds Indy and removes those limits. Students with a verified school email can get Pro at a lower price, and we may ask you to verify again.

Free trials

Some plans, such as the yearly plan, come with a free trial for eligible new subscribers. The app shows the trial length and the price before you start. Unless you cancel at least 24 hours before the trial ends, it turns into a paid subscription and you're charged at the end of the trial.

Billing and renewal

  • Payment is charged to your Apple Account when you confirm the purchase, or when a free trial ends.
  • Subscriptions renew automatically unless you turn off auto-renew at least 24 hours before the end of the current period.
  • Your account is charged for renewal within 24 hours before the end of the current period, at the current price.
  • You can manage or cancel your subscription in your Apple Account settings. If you cancel, Pro stays on until the end of the period you've paid for.

AI allowance and extended use

Pro includes a monthly allowance of AI use that covers normal coaching. If you reach it, some AI features pause until your allowance resets, or you can buy extended use: a one-time in-app purchase that adds more AI use to your account. Extended use is used up as you use AI features, does not renew, and can't be exchanged for cash or moved to another account.

Refunds

Apple processes all purchases under its own terms, and refunds are handled by Apple under its policies. We generally can't issue refunds ourselves. You can ask Apple for a refund at reportaproblem.apple.com.

4. Health and nutrition

IndexFit provides fitness tracking, scoring, coaching and information. It is not a medical device and does not give medical advice, diagnosis or treatment. Talk to a qualified healthcare professional before starting a new exercise or diet plan, especially if you are pregnant, have an injury or a medical condition, or have a history of disordered eating. Stop and get medical help if you feel pain, dizziness or discomfort.

Calorie, protein and weight targets, and calorie counts from photos or descriptions, are estimates. You use the Service, including plans and estimates made by Indy, at your own risk, and you are responsible for your training and eating decisions.

5. Indy and other AI features

  • Indy and IndexFit's other AI features are powered by AI models from other companies. Their answers, plans, check-ins and estimates can be inaccurate or incomplete, and they are not professional, medical or nutrition advice.
  • Indy can suggest changes to your plan, and its morning and evening check-ins can change upcoming workouts and runs for you. Each of those changes comes with an Undo. Review your plan and use your own judgment.
  • AI features send your data to AI providers only after you allow it, as described in our Privacy Policy. If you turn sharing off, some features stop working.
  • Don't send Indy anything you don't have the right to share, such as other people's private information or photos of them without their permission.
  • AI features can change, be limited or be unavailable at times.

We are not responsible for outcomes that come from relying on AI-generated content.

6. Leagues and competitions

Leagues are a way to play your friends using your training. Scores come from the data you log and sync, and we may correct, recalculate or remove scores and results when data is wrong, falsified or affected by a bug.

Competitions are free contests sponsored and run by IndexFit, with prizes we set. Each competition has its own official rules in the app, covering eligibility, dates, scoring and prizes, and those rules apply along with these Terms. No purchase is needed to enter or win, and Pro does not improve your chances. Apple is not a sponsor of, and is not involved in, any competition. We may disqualify entries that break the rules or these Terms.

7. Acceptable use

You agree not to:

  • Fake, manipulate or game workout data, scores, standings or competition results.
  • Harass, threaten, abuse or impersonate anyone in chats, groups, leagues or competitions.
  • Post content that is unlawful, infringing, hateful or sexually explicit.
  • Try to access, scrape, reverse engineer, overload or disrupt the Service, or get around its limits, including AI allowances.
  • Use the Service to break any law or anyone else's rights.

You can block or report other users from their profile or a message, and we review reports. We may remove content and suspend or end accounts that break these Terms.

8. Your content

You keep ownership of what you create or submit, such as messages, profile details, photos and imported routines. You give IndexFit a worldwide, non-exclusive, royalty-free license to host, store, copy, process and display that content only to run and provide the Service, including sending it to the providers that power AI features when you allow it. You're responsible for having the rights to what you submit, including workouts you import from other platforms.

9. Other services

IndexFit works with services run by others, such as Apple Health and Strava. Your use of those services is covered by their own terms and privacy policies, and we're not responsible for them. If you connect Strava, you choose which workouts are posted, and you can disconnect it anytime in Settings.

10. Intellectual property

The Service, including its software, design, logos and the IndexFit and Indy names, is owned by IndexFit and protected by intellectual property laws. Apart from the license above, no rights are given to you. You may not copy, modify, distribute or make derivative works from the Service without our permission.

11. Termination

You can stop using IndexFit and delete your account anytime in Settings. We may suspend or end your access if you break these Terms or if we need to in order to protect the Service or other people. Deleting your account does not cancel an App Store subscription, so cancel it in your Apple Account settings too. Parts of these Terms that should survive termination, such as intellectual property, disclaimers and limitation of liability, will survive.

12. Disclaimers

The Service is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We don't promise that the Service will be uninterrupted or error-free, or that scores, estimates and data will be perfectly accurate.

13. Limitation of liability

To the fullest extent allowed by law, IndexFit and its affiliates are not liable for any indirect, incidental, special, consequential or punitive damages, or any loss of data, profits or goodwill, arising from your use of the Service. Our total liability for any claim will not exceed the amount you paid us, if any, in the 12 months before the event that led to the claim.

14. Apple terms

These apply because IndexFit is distributed through the App Store:

  • These Terms are between you and IndexFit only, not Apple. Apple is not responsible for the app or its content.
  • Apple has no obligation to provide maintenance or support for the app.
  • If the app fails to meet any applicable warranty, you may tell Apple, and Apple will refund the purchase price (if any). To the fullest extent allowed by law, Apple has no other warranty obligation for the app.
  • Apple is not responsible for any claims about the app, including product liability claims, claims that the app fails to meet legal or regulatory requirements, and consumer protection claims.
  • Apple is not responsible for investigating, defending, settling or discharging any third-party claim that the app infringes intellectual property rights.
  • You confirm that you are not in a country subject to a U.S. Government embargo and are not on any U.S. Government list of restricted parties.
  • Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

15. Changes

We may update these Terms from time to time. When we make important changes, we'll update the date at the top and, where appropriate, tell you in the app. If you keep using the Service after the changes take effect, the updated Terms apply.
