terms of use

1. Acceptance and eligibility

By downloading, accessing, or using Hefty, you agree to these Terms. If you do not agree, do not use the app. You must be legally able to agree to these Terms; if you are not, a parent or guardian must review and accept them for you.

2. What Hefty provides

Hefty is a workout-planning and tracking tool. It may organize information you enter and generate suggestions, estimates, progressions, readiness guidance, or other training-related output. These outputs are general, automated suggestions only.

3. Not medical advice or professional coaching

Hefty is not a doctor, physiotherapist, dietitian, personal trainer, or other licensed professional. Nothing in the app is medical advice, diagnosis, treatment, rehabilitation guidance, or a substitute for individualized professional care.

Consult an appropriate doctor and qualified training professional before starting or changing an exercise program, especially if you have an injury, illness, disability, medical condition, are pregnant, take medication, or have any concern about whether exercise is safe for you.

4. Your responsibility and assumption of risk

Exercise can involve serious risks, including overexertion, equipment failure, bodily injury, illness, permanent disability, and death. You voluntarily assume the risks arising from your workouts and your use of Hefty.

You are responsible for choosing appropriate exercises, loads, repetitions, intensity, technique, equipment, supervision, environment, rest, and progression. Verify every suggestion against your own condition and the advice of qualified professionals. Stop exercising and seek appropriate help if you experience pain, dizziness, faintness, unusual shortness of breath, or other concerning symptoms.

5. No guarantee of accuracy, suitability, or results

Suggestions may be incomplete, inaccurate, unsuitable, too difficult, too easy, poorly timed, or otherwise constitute bad training for a particular person. Hefty does not guarantee that any recommendation is correct, safe, effective, current, or suitable for you, or that you will achieve any particular result.

6. Limitation of liability

To the fullest extent permitted by applicable law, Hefty and its owners, developers, affiliates, and service providers will not be liable for injuries, illness, death, property damage, bad training, overtraining, undertraining, unsuitable recommendations, loss of progress or data, or other losses arising from or related to your use of—or reliance on—the app, including misuse of the app or failure to obtain professional guidance.

The app is provided on an “as is” and “as available” basis without warranties of any kind, whether express, implied, or statutory, except where a warranty or liability cannot legally be excluded. Nothing in these Terms limits rights or remedies that cannot be waived under applicable law.

7. Purchases and subscriptions

Purchases are processed by Apple through the App Store. Prices, billing, renewals, cancellations, and refunds are governed by the terms shown at purchase and Apple’s applicable rules. Hefty may use RevenueCat to confirm purchase status and unlock paid features, but it does not receive your complete payment-card details.

8. Privacy

Our Privacy Policy explains how Hefty handles data and forms part of these Terms.

9. Acceptable use

Do not misuse Hefty, attempt unauthorized access, interfere with the app or its services, reverse engineer it except where the law permits, use it unlawfully, or infringe the rights of others.

10. Intellectual property

Hefty, including its design, software, branding, and original content, is owned by its developer or licensors and is protected by applicable intellectual-property laws. These Terms grant you a limited, personal, non-exclusive, non-transferable, revocable right to use the app for its intended purpose.

11. Availability, storage, and backups

We may change, suspend, or discontinue features. Workout data is intended to remain on your device or sync through your personal iCloud account when CloudKit sync is available. You are responsible for maintaining access to your device and Apple account and for any backups you consider necessary. We do not guarantee uninterrupted service or recovery of lost data.

12. Suspension and termination

You may stop using Hefty at any time. We may restrict or terminate access if reasonably necessary to protect the app, users, third parties, or comply with law. Sections that by their nature should survive termination—including responsibility, disclaimers, liability limitations, and intellectual-property terms—will survive.

13. Changes to Hefty or these Terms

We may update Hefty and these Terms as the product, practices, or law changes. We will revise the effective date and provide additional notice where required. Continuing to use Hefty after an update takes effect means you accept the updated Terms.

14. Applicable law and consumer rights

These Terms apply subject to mandatory laws and consumer protections in your place of residence. If any provision is unenforceable, the remaining provisions continue in effect. Nothing here deprives you of rights that applicable law does not allow you to waive.
