2. License
Subject to compliance with these Terms, we grant you a personal, non-exclusive, non-transferable, and revocable license to download, install, and use the Application on a mobile device that you own.
3. User Eligibility
The Application is intended for users of all ages interested in physical activity. To create an account, you must be at least 13 years old. If you are under 16 and reside in the European Economic Area, parental or legal guardian consent is required to use the Application (GDPR Art. 8).
4. Subscriptions and Payments
The Application offers both free and paid features available through subscriptions:
- Free plan: Basic workout tracking features with no time restrictions.
- Paid plans: Extended features including AI assistant, advanced statistics, and additional personalization options.
Subscriptions are billed through the Apple App Store or Google Play Store, depending on your platform. The following terms apply:
- Subscriptions renew automatically at the end of each billing period (monthly or annual), unless cancelled at least 24 hours before the end of the current period.
- The renewal fee is charged to the account associated with your Apple ID or Google account within 24 hours before the end of the current period.
- To cancel a subscription, use the account settings in the App Store (iPhone) or Google Play Store (Android). Deleting the application is not sufficient to cancel a subscription.
- Free trial period (if offered) ends upon subscription purchase or after the specified time. Any unused portion of the trial is forfeited upon purchase.
Current subscription prices are displayed on the purchase page within the application before confirming the transaction.
5. Right of Withdrawal
As a consumer, you have the right to withdraw from a digital service contract within 14 days without giving any reason (Article 27 of the Polish Consumer Rights Act of 30 May 2014, implementing EU Directive 2011/83/EU).
The Grynd subscription is a digital content service delivered immediately upon purchase. By activating the subscription, you expressly request immediate commencement of the service before the 14-day withdrawal period expires and acknowledge that you lose the right of withdrawal upon full performance of the service (Article 38(13) of the Polish Consumer Rights Act).
Refunds for subscription purchases are handled in the first instance by the store operator where the purchase was made (Apple App Store or Google Play), in accordance with their refund policies. If the store operator declines a refund, you may contact us at support@gryndapp.com.
6. Complaints
Complaints regarding subscriptions and the operation of the Application should be submitted:
- via the "Help / Contact" screen in the Application, or
- by e-mail to: support@gryndapp.com.
We process complaints within 14 days of receipt. Failure to respond within this period is deemed acceptance of the complaint. The response will be sent to the email address associated with your account or the address provided in the complaint.
7. Artificial Intelligence (AI) Features
The Application includes an optional AI assistant "Grynd" that generates personalized training guidance. Use of AI features:
- Requires explicit consent before first use (AI consent screen in the Application).
- Consent may be withdrawn at any time in the Application Settings.
- Chat messages are transmitted to external AI service providers for the purpose of generating responses and automated content moderation.
- Details of AI data processing are described in our Privacy Policy.
8. Medical Disclaimer
The Application and its associated AI features do not provide medical advice. Content generated by the AI assistant is educational and informational only. It does not constitute professional medical advice, diagnosis, or treatment. You agree that you use the Application at your own risk. Consult a physician before starting or changing a training plan, especially if you have any medical conditions or health limitations.
9. User Content
You retain ownership rights to the data you enter (workouts, body measurements, chat messages). By using the application, you grant us a limited license to process and securely store this data to the extent necessary to provide the service. You agree not to submit content that is illegal, harmful, offensive, or that violates the rights of third parties.
10. Content Moderation
To ensure user safety, messages sent to the AI assistant are subject to automated moderation. Content that violates safety policies may be blocked. Each AI response can be reported using the "Report" button in the chat interface — reports are reviewed by our support team.
11. Limitation of Liability
To the fullest extent permitted by law, we shall not be liable for any direct, indirect, or incidental damages (including injuries, health complications, or data loss) arising from the use of the Application or content generated by the AI assistant. This limitation does not exclude liability that cannot be excluded under mandatory consumer protection law.
12. Termination
We reserve the right to block access to the Application at any time, with immediate effect, if you violate the provisions of these Terms. In case of account suspension, active subscriptions are not automatically cancelled — you must cancel them directly in your store settings (App Store / Google Play).
13. Changes to These Terms
We reserve the right to update these Terms. We will notify you of material changes (e.g., expansion of data processing scope, new processing purposes, subscription price changes) via in-app notification or the email address associated with your account, with reasonable advance notice. Editorial, clarifying, or organizational changes take effect upon publication of the updated version on this page with a new update date. Continued use of the Application after changes are published constitutes acceptance of those changes.
14. Governing Law and Dispute Resolution
These Terms are governed by the laws of the Republic of Poland. If you are a consumer in another European Union country, you additionally benefit from the mandatory consumer protection laws of your country of residence. Any disputes arising from the use of the Application shall be resolved by the court with jurisdiction over the Publisher's registered office, subject to consumers' rights to bring claims before the courts of their place of residence.
