1. Acceptance of Terms
These Terms of Use (the “Terms”) govern your use of Chisel, the abs training app for iOS (the “App”), operated by Piotr Rudnicki (“we”, “us”). By downloading or using the App you agree to these Terms. If you do not agree, do not use the App.
2. The App
Chisel is a six-week, no-equipment abs program: short daily workouts, an exercise library with illustrated instructions, and progress tracking. The App works on your device. It has no user accounts and does not require sign-in.
3. Health and Safety
The App provides general fitness information and is not medical advice. Consult a doctor before starting any exercise program, especially if you are pregnant, have a medical condition, an injury, or are recovering from surgery.
Stop exercising immediately if you feel pain, dizziness, or shortness of breath that does not go away. You use the App and perform all exercises at your own risk.
4. Subscriptions and Payments
The App offers an auto-renewing subscription (“Chisel Annual”) that unlocks the full program. Payment is charged to your Apple ID account when you confirm the purchase. The subscription renews automatically each year unless you cancel at least 24 hours before the end of the current period. Any free trial, price and billing period are shown in the App before you buy.
You manage or cancel your subscription in your Apple ID account settings (Settings > [your name] > Subscriptions on iOS). Deleting the App does not cancel the subscription. Refunds are handled by Apple under its own terms; we cannot process refunds directly.
You can restore a previous purchase from within the App using the Restore Purchases option.
5. Your Data
Your workout history, progress and settings are stored on your device. If you delete the App or reset your device, this data may be lost. We do not provide cloud backup and do not guarantee that data will be preserved. See our Privacy Policy for details.
6. Intellectual Property
The App, including its code, design, text, exercise illustrations and logo, is owned by us or our licensors and is protected by law. We grant you a limited, personal, non-exclusive, non-transferable, revocable licence to use the App for your own non-commercial fitness purposes. You may not copy, modify, reverse engineer, resell or create derivative works of the App, except where the law allows.
7. Acceptable Use
You agree not to misuse the App, attempt to interfere with its operation, or use it for any unlawful purpose.
8. Disclaimer of Warranties
The App is provided “as is” and “as available”, without warranties of any kind, to the fullest extent permitted by law. We do not warrant that the App will be uninterrupted or error-free, or that it will achieve any particular fitness result.
9. Limitation of Liability
To the fullest extent permitted by law, we are not liable for any indirect, incidental, special or consequential damages, or for any loss of data, arising from your use of the App. Our total liability for any claim relating to the App is limited to the amount you paid for the App or subscription in the twelve months before the claim. Nothing in these Terms limits liability that cannot be limited under applicable law.
10. Termination
You may stop using the App at any time. We may suspend or end access to the App if these Terms are violated or if we discontinue the App. Sections that by nature should survive termination will survive.
11. Changes to These Terms
We may update these Terms from time to time. The date at the top of this page shows when they were last updated. Continued use of the App after changes take effect means you accept the updated Terms.
12. Governing Law
These Terms are governed by the laws of the country in which the developer is established, without regard to conflict-of-law rules. Mandatory consumer protections in your country of residence are not affected.
