Terms of Use
These terms govern your use of Hardround: Train Like Athletes ("Hardround"), an athletic training app for iPhone and Android, operated by Seungjun Lee (Huzlee), an individual developer in the Republic of Korea. By creating an account or subscribing you agree to them.
1. What Hardround is
Hardround builds a training program from the answers you give, runs your sessions with a timer, teaches movements through built-in lessons and links you save, logs what you trained and, where it is switched on, reviews still pictures of your form with an AI coach.
Hardround is not medical advice and not a substitute for a coach, a doctor or a physiotherapist. The coach's review is an AI's judgement from a handful of still pictures, not a measurement.
2. Train safely
Athletic training — sprints, jumps, lifting and conditioning — is physically demanding and carries a risk of injury. Before you start, check with a doctor if you have a heart condition, high blood pressure, a recent injury or surgery, are pregnant, or are unsure whether hard exercise is right for you. Train within your limits, warm up, use a clear space and suitable equipment, and stop at once if you feel sharp, joint, neck or head pain, chest pain, dizziness or shortness of breath. Choose loads you can control, and learn a lift from its lesson before adding weight. You are responsible for how and where you train.
You must be at least 14 years old to use Hardround.
3. Your account
You sign in with Apple, Google or an email address so your training record is yours and survives a new phone. Keep your sign-in secure. You can delete your account and everything stored with it at any time in the app (Home → ⚙ → Settings → Account and backup → Delete account) or by writing to us — see the account deletion page.
4. Subscriptions
- Hardround is paid-only. Onboarding is free; using the app after it requires an active subscription, monthly or annual.
- Subscriptions are sold and billed by the Apple App Store or Google Play, which show the price in your currency before you confirm. Where a free trial is offered it is shown on the purchase screen; you are charged when it ends unless you cancel before.
- Subscriptions renew automatically at the same price unless cancelled — on the App Store at least 24 hours before the period ends. Manage or cancel in your App Store or Google Play account settings. Deleting your Hardround account does not cancel a subscription.
- Refunds are handled by Apple or Google under their own policies.
- On iOS, your purchase is also governed by Apple's Standard Licensed Application End User License Agreement. If these terms conflict with it for an App Store purchase, Apple's agreement governs.
5. Your content
Your training record, notes and labels are yours. You give us the permission we need to store and show them to you, and nothing more. Links you save to Instagram, TikTok or YouTube posts stay the property of their owners; Hardround keeps the link, never a copy of the video. Do not use Hardround to store content you have no right to.
6. Acceptable use
Do not reverse-engineer, resell or disrupt the service, try to reach another person's data, or use the coach to produce content that is unlawful or harmful.
7. Availability and changes
We work to keep Hardround running but cannot promise it will always be available or error-free. Features may change. If we change these terms in a material way we will tell you in the app before the change takes effect.
8. Liability
To the extent the law allows, Hardround is provided "as is", and we are not liable for injury or loss arising from training you choose to do, or for indirect or consequential loss. Nothing in these terms limits liability that cannot be limited by law, or your statutory rights as a consumer.
9. Law and contact
These terms are governed by the laws of the Republic of Korea. Disputes go to the courts of the operator's domicile where the law allows; this does not limit any right you have as a consumer to bring a claim where you live. Questions: Seungjun Lee, seungjun@huzlee.com.
