1. Acceptance

By downloading or using FitSync, you agree to these Terms of Service. If you do not agree, please do not use the app. These terms are governed by Danish law, and any disputes shall be subject to the jurisdiction of the Danish courts.

2. The service

FitSync is a fitness tracking application developed and operated by Min Virksomhed v.Mathias Sørsdal (CVR 44426293), Kastet 86, 7700 Thisted, Denmark.

FitSync is offered in two tiers:

• FitSync Core (Free) — workout logging, food diary, body measurements, progress photos, and analytics. Available free of charge with no time limit.
• FitSync Pro (Paid subscription) — everything in Core, plus unlimited access to MyCoach, the AI coaching assistant, and any additional Pro features released during the subscription period. Priced at $3/month — billed via Apple App Store or Google Play.

3. Account

You must create an account to use FitSync. You are responsible for maintaining the confidentiality of your login credentials and for all activity under your account. You must be at least 16 years old to create an account.

4. Subscription billing and renewal

FitSync Pro subscriptions are billed through Apple App Store (iOS) or Google Play (Android). Subscriptions automatically renew at the end of each billing period unless you cancel at least 24 hours before the renewal date. You can manage or cancel your subscription in your device's App Store or Google Play account settings. We do not process or store payment card data directly.

5. Price changes

We reserve the right to change subscription pricing. You will be notified of any price change with at least 30 days' notice via in-app notification or email. Continued use of the subscription after the effective date constitutes acceptance of the new price.

6. Acceptable use

You may not:

• Reverse engineer, decompile, or disassemble any part of the app.
• Use the app for any unlawful purpose or in violation of these terms.
• Attempt to gain unauthorised access to any part of the service or its infrastructure.
• Resell or sublicense access to FitSync or MyCoach to third parties.

7. Availability and changes

We aim to keep FitSync available at all times but do not guarantee uninterrupted service. We may update, modify, or discontinue features at any time. For paid subscribers, significant reductions in Pro functionality will be communicated with reasonable advance notice.

8. Limitation of liability

To the fullest extent permitted by Danish law, we are not liable for indirect, incidental, or consequential damages arising from use of the service. Our total liability to you shall not exceed the total amount you paid us in the 12 months preceding the claim. Nothing in these terms limits liability for death or personal injury caused by negligence, or for fraudulent misrepresentation.

9. Health disclaimer

FitSync and MyCoach provide general fitness and nutrition information for informational purposes only. They are not a substitute for professional medical advice, diagnosis, or treatment. Always consult a qualified health professional before starting a new exercise or nutrition programme, especially if you have a pre-existing medical condition.

10. Termination

You may delete your account at any time from within the app. We reserve the right to suspend or terminate accounts that violate these terms, with notice where reasonably practicable. On termination, your data will be deleted in accordance with our Privacy Policy.

As a consumer resident in the European Union or Denmark, you have the right to withdraw from a purchase of FitSync Pro within 14 calendar days of the date your subscription begins, without giving any reason, in accordance with the Danish Consumer Contracts Act (Forbrugeraftaleloven) and EU Directive 2011/83/EU.

Waiver of withdrawal right for digital services

If you have not yet used the service

If you subscribed to FitSync Pro but have not activated or used any Pro features, you may request a refund within 14 days by contacting us at mattyofttraining@gmail.com with the subject line "Withdrawal — FitSync Pro".

Please include:

• Your full name and the email address registered to your FitSync account.
• Your purchase date and platform (App Store or Google Play).
• A clear statement that you wish to withdraw from the purchase contract.

Refunds for App Store purchases are processed by Apple. Refunds for Google Play purchases are processed by Google. We will refund any amount received directly within 14 days of receiving your valid withdrawal notice.

This right does not apply to

• FitSync Core — no payment is taken, so the withdrawal right is not applicable.
• Subscriptions where digital service delivery has already commenced with your prior explicit consent, as described above.

What MyCoach is

MyCoach is an AI-powered coaching assistant available to FitSync Pro subscribers. It is designed to help you with workout programming, nutrition guidance, and progress analysis by drawing on your personal fitness logs stored in FitSync.

MyCoach is powered by a large language model (LLM) provided by a third-party AI service provider. It is not a human coach, medical professional, or licensed dietitian.

How MyCoach uses your data

When you send a message to MyCoach, the following data is included in the request sent to the AI provider:

• Your message and recent conversation history with MyCoach.
• Relevant fitness data from your FitSync account — such as recent workouts, logged food entries, body weight measurements, and goals — to provide personalised, context-aware responses.

This data is transmitted securely (TLS encryption) to the AI provider for the sole purpose of generating your response. We have configured our agreement with the AI provider to opt out of using your data for AI model training. Your fitness data is not retained by the AI provider beyond the duration needed to generate a response.

Limitations and important caveats

• MyCoach can and does make mistakes. Treat its output as a starting point, not a definitive prescription.
• MyCoach does not have real-time access to medical databases or current scientific literature.
• Do not share sensitive personal information (e.g. medical diagnoses, prescription medication details) with MyCoach beyond what is relevant to fitness tracking.

Automated decision-making

MyCoach does not make any automated decisions that produce legal or similarly significant effects on you within the meaning of GDPR Art. 22. All outputs are informational suggestions which you remain entirely free to act on or disregard.

Feedback and corrections

If MyCoach provides advice you believe is incorrect or potentially harmful, please email us at mattyofttraining@gmail.com. We review all feedback to improve the system's safety guidance and accuracy.
