Terms of Use (End User License Agreement) for Fitness
Last updated: Oct 2026
Effective Date: Oct 2026
These Terms of Use ("Terms" or "EULA") are a legal agreement between you and QLines ("we," "us," or "our") for the Fitness: Workout & Macro Log mobile application ("App", shown as Qlines Fitness on your home screen) on iOS. By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App.
1. Description of the App
Fitness is a privacy-first training and nutrition companion. It builds a weekly training plan around your goal, schedule and equipment, lets you log every set, shows your streaks, adherence, volume trends and personal records, includes an exercise library (with your own custom exercises), calculates daily nutrition targets (calories, protein, carbohydrates, fat, water and creatine), offers a short supplement guide, and sends the training-day reminders you enable. All data is stored locally on your device. The App does not provide medical advice.
2. License Grant
We grant you a limited, non-exclusive, non-transferable, revocable license to use the App for personal, non-commercial use, subject to these Terms and the Apple Media Services Terms and Conditions. You may not copy, modify, distribute, reverse engineer, or create derivative works of the App.
3. Subscriptions and In-App Purchases
3.1 Subscription Plans
Fitness offers auto-renewable subscriptions (“Fitness Premium”) to unlock premium features:
- Monthly subscription – Billed per month (US price $5.99). Prices vary by country; the App shows the price in your currency before you confirm a purchase.
- Yearly subscription – Billed once per year (US price $34.99). Prices vary by country.
- Free trial – A 1-week free trial is offered to new subscribers whose Apple Account is eligible. After the trial, your subscription will automatically renew and you will be charged unless you cancel at least 24 hours before the trial ends. If notifications are allowed, the App reminds you 2 days before the trial ends.
The App shows the price, the billing period and any free trial before you confirm a purchase.
3.2 Premium Features
A Premium subscription unlocks the following features, which may include further features over time:
- Unlimited training plans (without Premium: 1 plan)
- Unlimited custom exercises (without Premium: 3)
- Full nutrition coaching
- Advanced progress insights
- Priority reminders
Everything else in the App, including logging your workouts, the exercise library, your streaks and your existing data, is available without a subscription.
3.3 When a Subscription Ends
Your plans, sessions and other data stay on your device. If your subscription ends, you can still view them; the Premium features are locked again, and the limits in section 3.2 apply to new plans and custom exercises.
3.4 Auto-Renewal
Subscriptions automatically renew at the end of each period (monthly or yearly) unless you turn off auto-renewal at least 24 hours before the end of the current period. Payment is charged to your Apple Account at confirmation of purchase, or when the free trial ends, and for renewal within 24 hours prior to the end of the current period.
3.5 Cancellation and Refunds
You can cancel or manage your subscription in your device Settings → Apple Account → Subscriptions. Cancellation takes effect at the end of the current billing period; if you cancel during a free trial, you are not charged. Refunds are handled by Apple in accordance with Apple's refund policy; we cannot issue refunds directly.
3.6 Restoring Purchases
On a new device, or after reinstalling the App, sign in with the same Apple Account and tap Restore Purchases in the App (on the paywall or in Settings).
3.7 Payment
All payments are processed by Apple. You agree to Apple's payment terms. We do not store or have access to your payment details. Purchases are verified on your device with StoreKit 2.
4. Privacy
Your use of the App is also governed by our Privacy Policy for Fitness, which describes what data the App stores (locally on your device), how it is used, and your rights. By using the App, you consent to the Privacy Policy.
5. Health and Fitness Disclaimer
Fitness is a planning and tracking tool. It is not a medical device and does not provide medical advice.
The training plans, exercise instructions, nutrition targets and supplement information in the App are general information for educational purposes. They are not a substitute for advice from a doctor, physiotherapist, dietitian or qualified trainer, and they are not tailored to any medical condition.
Speak to a qualified professional before starting a new exercise or nutrition programme, especially if you have a health condition, are pregnant, take medication, or have an injury. Stop exercising and seek medical help if you feel pain, dizziness or discomfort. You exercise at your own risk.
6. Plans, Nutrition Targets and Supplement Guide
6.1 How They Are Produced
- Training plans are generated on your device from the goal, experience level, training days and equipment you choose
- Nutrition targets (calories, protein, carbohydrates, fat, water, creatine) are estimates calculated from the profile you enter
- The supplement guide summarises general information with an evidence rating (Strong, Good or Limited); it is not a recommendation for you personally
6.2 Accuracy
- We make reasonable efforts to keep the information accurate, but we do not guarantee completeness or accuracy
- Estimates are only as good as the information you enter and may not suit every individual
- Your progress statistics are derived from your own logs; they are summaries, not medical assessments
7. Acceptable Use
You agree to use the App only for lawful, personal purposes. You may not:
- Use the App's content or data for commercial purposes without our written consent
- Attempt to reverse engineer, decompile, or extract source code from the App
- Circumvent any access or payment controls
- Use the App in any way that could damage, disable, or impair its functionality
We may suspend or terminate your access if we believe you have violated these Terms.
8. Intellectual Property
The App, including its design, code, exercise library, guides and content, is owned by us or our licensors and is protected by copyright and other intellectual property laws. You do not acquire any ownership rights by using the App.
Data you enter into the App (profile, custom exercises, workout logs, body-weight entries) remains yours. We do not claim ownership of your content.
9. Disclaimers
The App is provided "as is" and "as available." We do not warrant that the App will be uninterrupted, error-free, or free of harmful components. Specifically:
- Training plans are generated algorithmically and may not be suitable for every individual
- Nutrition and supplement information is general and may not account for your circumstances
- Reminders depend on your device's notification settings and may not be delivered
10. Limitation of Liability
To the maximum extent permitted by applicable law, we (and our affiliates, officers, and employees) shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data or profits, arising from your use of the App, reliance on its training or nutrition guidance, any injury, or any subscription. Our total liability shall not exceed the amount you paid us in the twelve (12) months preceding the claim.
Some jurisdictions do not allow these limitations; in such cases, our liability is limited to the fullest extent permitted by law.
11. Termination
We may terminate or suspend your access to the App at any time for breach of these Terms. You may stop using the App at any time. Upon termination, your license to use the App ends. Since all data is stored locally on your device, you retain access to your data until you delete the App. Provisions that by their nature should survive (including sections on liability, intellectual property, the health and fitness disclaimer, and governing law) will survive termination.
12. Changes to These Terms
We may update these Terms from time to time. We will post the updated Terms at this URL and update the "Effective Date." For material changes, we may provide notice in the App or by other reasonable means. Your continued use of the App after changes constitutes acceptance of the updated Terms. If you do not agree, you must stop using the App.
13. Governing Law and Disputes
These Terms are governed by the laws of Germany. Any disputes shall be resolved in the courts of Germany. If you are a consumer in the EU, you may also have rights under the laws of your country of residence.
