HIITTracker — Terms and Conditions

Effective date: September 19, 2025

Last updated: September 19, 2025

These Terms and Conditions (the “Terms”) govern your use of the HIITTracker mobile applications for iOS and watchOS (the “App”). By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App.

1. Who We Are

HIITTracker is a fitness application that helps you plan and track high‑intensity interval training (HIIT) workouts, including optional Apple Watch heart‑rate integration via HealthKit and optional Spotify playback controls. We do not operate backend servers; the App primarily stores data on your device and/or in Apple’s Health app if you grant permission.

2. Eligibility

You must be at least 13 years old to use the App. If you are between 13 and 18 (or the age of majority in your jurisdiction), you may use the App only with the consent and supervision of a parent or legal guardian who agrees to be bound by these Terms.

3. Safety Warning and Medical Disclaimer

  • The App is provided for general fitness and informational purposes only. It is not a medical device, does not provide medical advice, diagnosis, or treatment, and has not been cleared or approved by any regulatory authority.
  • Always consult a physician before beginning any exercise program, especially high‑intensity training. Exercise entails inherent risks, which may include serious injury or death. You assume all risks associated with using the App.
  • Stop exercising immediately if you feel pain, faintness, dizziness, shortness of breath, chest pain, or other concerning symptoms, and seek medical attention.
  • The App is not intended for emergency use. In an emergency, call your local emergency number.
  • To the maximum extent permitted by law, we disclaim any responsibility for decisions you make based on information provided by the App.

4. HealthKit and Data Accuracy

  • With your permission, the App may read certain health data (e.g., heart rate, active energy, distance) and write workout data to Apple’s Health app via HealthKit. You control permissions in iOS/watchOS Settings and the Health app.
  • HealthKit data must never be used for advertising, marketing, or tracking. We do not use HealthKit data for such purposes.
  • Sensor data (including optical heart rate) may be inaccurate or delayed. Environmental factors, device fit, skin perfusion, motion, and other conditions can affect accuracy. The App’s calculations, estimates, charts, and alerts may be incomplete or inaccurate. Do not rely on the App as a substitute for professional judgment.

5. Third‑Party Services

  • The App may interact with third‑party services such as Spotify and Apple Watch/HealthKit. Your use of those services is subject to their terms and privacy policies. We do not control and are not responsible for third‑party services.
  • If you connect Spotify, your device communicates directly with Spotify’s services to control playback and fetch metadata/artwork. We do not receive your Spotify login credentials. Availability of playback features depends on Spotify’s service and your account.

6. License and Acceptable Use

  • We grant you a limited, revocable, non‑exclusive, non‑transferable license to install and use the App on Apple‑branded devices you own or control, solely for personal, non‑commercial fitness purposes and strictly in accordance with these Terms and Apple’s App Store Terms.
  • You must not: (a) copy, modify, reverse engineer, decompile, disassemble, or create derivative works of the App except to the extent permitted by law; (b) circumvent security or access‑control mechanisms; (c) use the App in a manner that infringes any law, regulation, or third‑party right; (d) use the App to provide medical advice; (e) misuse HealthKit data (including for advertising or tracking); (f) use the App while engaging in activities where distraction could cause injury (e.g., driving, cycling on roads, operating machinery).

7. User Content and Local Storage

  • The App may store workout records, intervals, and other data locally on your device and/or in Apple’s Health app under your control. You are responsible for maintaining backups of your data. Deleting the App may remove locally stored data.
  • We do not operate servers for syncing or backup. Data loss can occur (e.g., device failure, deletion). To the maximum extent permitted by law, we are not liable for data loss.

8. Changes, Updates, and Availability

  • We may update the App (including adding, changing, or removing features) and these Terms from time to time. If changes are material, we will take reasonable steps to notify you (e.g., in‑app notice). Your continued use after changes take effect constitutes acceptance.
  • The App may be unavailable, inaccurate, or interrupted due to maintenance, updates, device compatibility, third‑party service outages (e.g., Spotify), or other reasons. We are not responsible for such unavailability.

9. No Warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON‑INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE. WE DO NOT WARRANT THAT THE APP WILL BE ACCURATE, RELIABLE, ERROR‑FREE, SECURE, UNINTERRUPTED, OR THAT DEFECTS WILL BE CORRECTED, OR THAT THE APP WILL MEET YOUR REQUIREMENTS.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, ENHANCED, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, GOODWILL, DATA, FITNESS RESULTS, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE APP OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID (IF ANY) FOR THE APP IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) USD $50.

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF LIABILITY FOR CERTAIN DAMAGES; IN SUCH JURISDICTIONS, OUR LIABILITY WILL BE LIMITED TO THE MAXIMUM EXTENT PERMITTED BY LAW.

11. Indemnification

You agree to defend, indemnify, and hold harmless us and our officers, directors, employees, contractors, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys’ fees) arising out of or in any way connected with your: (a) access to or use of the App; (b) violation of these Terms or applicable law; (c) reliance on information provided by the App; (d) misuse of HealthKit or third‑party services.

12. Suspension and Termination

We may suspend or terminate your access to the App at any time if we reasonably believe you have violated these Terms, pose a risk, or as required by law. You may stop using the App at any time by uninstalling it. Upon termination, the license granted to you ends immediately.

13. In‑App Purchases and Fees (If Any)

If we introduce paid features or subscriptions in the future, you will be presented with pricing and terms at the point of purchase. Payments are processed by Apple, and Apple’s terms apply. To the extent permitted by Apple’s policies and applicable law, purchases are final and non‑refundable.

14. App Store Terms; Apple as Third‑Party Beneficiary

You acknowledge that these Terms are between you and us, not Apple. We, not Apple, are solely responsible for the App. Apple has no obligation to furnish maintenance or support. To the extent required by Apple’s policies, Apple and its subsidiaries are third‑party beneficiaries of these Terms and may enforce them against you.

15. Governing Law; Dispute Resolution

These Terms are governed by the laws of [Insert governing law and jurisdiction], without regard to conflicts‑of‑law principles. You agree to the exclusive jurisdiction and venue of the courts located in [Insert venue]. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

If you reside in the European Economic Area, the United Kingdom, or a jurisdiction that requires local consumer protections, you may have additional rights that cannot be waived under local law. These Terms are intended to be interpreted to preserve such non‑waivable rights.

16. Export and Sanctions

You represent that you are not located in a country subject to U.S. Government embargo or on any U.S. Government list of prohibited parties. You agree to comply with all applicable export control and sanctions laws.

17. Miscellaneous

  • Entire Agreement: These Terms and any policies referenced here (including our Privacy Policy) are the entire agreement between you and us regarding the App.
  • Severability: If any provision is found unenforceable, it will be modified to the minimum extent necessary to make it enforceable, and the remaining provisions will remain in effect.
  • No Waiver: Our failure to enforce a provision is not a waiver of our right to do so later.
  • Assignment: You may not assign or transfer these Terms; we may assign them as part of a merger, acquisition, asset sale, or by operation of law.
