• Payment is charged to your Apple ID account at confirmation of purchase

Cancellation

• You can cancel your subscription at any time through your iPhone Settings → Apple ID → Subscriptions

We may update subscription prices from time to time. You will be notified in advance of any price changes, and any increase will apply only after the current billing period ends.

4. User Responsibilities

When using LensFit, you agree to:

• Use the app only for personal, non-commercial fitness tracking purposes
• Not attempt to reverse engineer, decompile, or extract the source code of the app
• Not use the AI Scan features to analyze photos of other people without their consent
• Not use the app in any manner that could damage, disable, or impair the service
• Not attempt to gain unauthorized access to any systems connected to the app
• Not redistribute, resell, or sublicense any content generated by the app

5. Health and Fitness Disclaimer

Specifically:

• Body fat estimates are approximations based on visual AI analysis and may differ significantly from clinical measurements (DEXA scan, hydrostatic weighing, etc.)
• Physique scores and assessments are AI-generated opinions and should not be used as diagnostic tools
• Exercise recommendations (form corrections, improvement plans, sets/reps) are general guidance and may not be appropriate for your specific physical condition, injuries, or limitations
• Machine identification and usage instructions are AI-generated and may contain errors — always verify equipment setup before use
• Muscle battery levels are estimated calculations and do not reflect actual physiological recovery

You are solely responsible for your own health and safety. Always consult a qualified healthcare professional or certified personal trainer before starting a new exercise program, changing your training routine, or if you have any health concerns, injuries, or medical conditions.

We are not liable for any injuries, health issues, or damages that may result from following the app's recommendations or using the app's features.

6. AI-Powered Features

LensFit uses artificial intelligence (Google Gemini API) to power its Scan features. You acknowledge and agree that:

• AI analysis results are generated automatically and may contain errors or inaccuracies
• Machine identification may not always be correct — always verify the machine before use
• Form analysis is based on a single photo and cannot capture the full complexity of a movement
• Body composition estimates are visual approximations, not clinical measurements
• AI features require an active internet connection and may be temporarily unavailable
• Photos sent for analysis are processed by Google's Gemini API (see our Privacy Policy for details)
• We do not guarantee the availability, accuracy, or reliability of AI-generated content

7. Intellectual Property

All content within LensFit, including but not limited to the app design, user interface, icons, graphics, text, exercise database, Battery Engine system, and AI prompt engineering, is the property of Anthony Granier and is protected by applicable copyright and intellectual property laws.

You may not:

• Copy, reproduce, or distribute any part of the app
• Use the LensFit name, logo, or branding without written permission
• Create derivative works based on the app's design or functionality
• Screenshot or record AI-generated content for commercial purposes

Your Content

You retain ownership of all data you create within the app (workout logs, photos, profile information). Since all data is stored locally on your device, you maintain full control over your content at all times.

8. Service Availability

We strive to keep LensFit available and functional at all times. However:

• AI Scan features depend on third-party services (Google Gemini API) and may experience downtime or interruptions beyond our control
• We may release updates that modify, add, or remove features
• We may temporarily suspend the service for maintenance or improvements
• Core workout tracking features work offline and are not dependent on external services

We are not liable for any loss of data, interruption of service, or inability to access features due to circumstances beyond our reasonable control.

9. Limitation of Liability

To the maximum extent permitted by applicable law:

• LensFit is provided "as is" and "as available" without warranties of any kind, whether express or implied
• We do not warrant that the app will be error-free, uninterrupted, or free from harmful components
• We are not responsible for any physical injury, health issue, or damage resulting from the use of the app or reliance on its content
• Our total liability to you for any claims arising from or related to the use of the app shall not exceed the amount you paid for the app or subscription in the 12 months preceding the claim
• We are not liable for any indirect, incidental, special, consequential, or punitive damages

10. Termination

You may stop using LensFit at any time by deleting the app from your device. This will permanently delete all locally stored data.

We reserve the right to terminate or restrict your access to premium features if you violate these Terms, misuse the AI features, or engage in fraudulent activity. In such cases, no refund will be provided for the remaining subscription period.

11. Modifications to These Terms

We may update these Terms from time to time. The "Last updated" date at the top of this page will be revised accordingly. Continued use of the app after changes constitutes your acceptance of the revised Terms.

For significant changes that affect your rights, we will make reasonable efforts to notify you through the app or via the email associated with your account (if applicable).

12. Governing Law

These Terms are governed by and construed in accordance with the laws of France, without regard to its conflict of law provisions. Any disputes arising from these Terms or the use of the app shall be subject to the exclusive jurisdiction of the courts of France.

If you are a consumer in the European Union, you also benefit from mandatory consumer protection provisions of the laws of your country of residence. Nothing in these Terms affects your rights as a consumer under applicable EU law.

13. Apple App Store Terms

These Terms are between you and Anthony Granier (not Apple). The following additional terms apply:

• Apple has no obligation to provide maintenance or support for LensFit
• Apple is not responsible for addressing any claims related to the app (product liability, legal compliance, or intellectual property)
• In the event of any failure of the app to conform to an applicable warranty, you may notify Apple for a refund of the purchase price (if applicable). Apple has no further warranty obligation
• Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you

If any provision of these Terms is found to be unenforceable or invalid, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will remain in full force and effect.
