Terms of Service (EULA).

1. Publisher

The publisher of the Grynd AI application is:

Tomasz Guziak
ul. Sandomierska 13/120, 26-611 Radom, Poland
Tax ID (NIP): 9482630105
Email: support@gryndapp.com

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. To use the Application you need a mobile device running a supported version of iOS or Android and an internet connection — current requirements are stated on the Application's listing in the App Store and Google Play.

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 and activity tracking features with no time restrictions. Selected elements of the free plan are subject to quantitative limits (e.g. the number of routines and custom exercises) indicated within the Application.
• Paid plans: AI Analyst — automated, periodic analyses of your activity, on-demand AI tools (including the AI-assisted nutrition diary and visual analysis), and the Application without quantitative limits; this plan does not include the assistant chat. AI Coach — everything in the AI Analyst plan, plus chat with the AI assistant, limited to 30 messages per day.
• Technical restrictions on AI features: features based on artificial intelligence may have technical restrictions associated with them — for example, the number of requests you may submit or the number of responses you may receive within a certain period of time. These restrictions reset automatically.

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 (according to the plan you selected), unless cancelled before that period ends. In the App Store, cancellation must take place 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 from your device does not cancel your subscription.
• A free trial period (if offered) ends upon purchase of a subscription or after the specified time has elapsed.

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 this contract within 14 days of concluding it, without giving any reason (Article 27 of the Polish Consumer Rights Act of 30 May 2014, implementing EU Directive 2011/83/EU). It is enough to tell us at support@gryndapp.com.

If, at your request, we began providing the service before that period expired, upon withdrawal you pay only for the period up to your withdrawal — an amount calculated in proportion to the part of the billing period you have used (Article 35 of the Polish Consumer Rights Act). We refund the remainder of the fee.

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. This does not limit the right of withdrawal described above — if the store operator declines a refund, write to us at support@gryndapp.com and we will settle the withdrawal directly.

6. Complaints

Complaints regarding subscriptions and the operation of the Application should be submitted:

• via the "Report a Bug / Support" screen in the Application's Settings, 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 optional AI features that support you in training, nutrition, and activity analysis. They operate in two modes: an in-chat assistant (answers your questions and, at your instruction, performs tasks such as logging meals, goals, and workouts) and automated, periodic overviews of a selected area of your activity (e.g., sleep, nutrition, workouts). 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.
• Includes, among other things: a training-and-nutrition assistant, an AI-assisted nutrition diary (meal-photo analysis, nutritional-value estimation), visual analysis of uploaded photos or videos, and periodic summaries of your data. The scope, frequency, and subject matter of AI features may change and evolve over time.
• Relevant data (message content, selected training, nutrition, and health data, and uploaded media) is transmitted to external artificial intelligence model providers based in the United States — only after consent is granted and without using the data to train models; content is not retained longer than necessary (some providers apply a zero-retention principle, while others retain content for a short period solely to detect abuse).
• We do not store uploaded photos or videos — we process them in real time only.
• Details of AI data processing are described in our Privacy Policy.

8. Medical Disclaimer

Grynd is not a medical device, and its AI features do not provide medical advice — this is support, and it does not replace advice from a doctor. Content generated by AI and indicators coming from devices (e.g. sleep, heart rate, HRV) are for general reference only, may be inaccurate or incorrect, and are not intended for diagnosis or for assessing your state of health. Consult a physician before starting or changing a training plan or diet, especially if you have any medical conditions or health limitations.

9. User Content

You retain ownership rights to the data you enter (workouts, activities, body measurements, nutrition, 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

We are liable for damage caused by non-performance or improper performance of this contract on the terms set out in Polish law, within the limits of the normal consequences of our act or omission. We do not exclude or limit our liability to the extent that doing so would be unlawful — this applies in particular to personal injury, to damage caused intentionally, and to liability arising from mandatory consumer protection law. We are not, however, liable for the effects of circumstances beyond our control, in particular the operation of your device, operating system, app store, or internet provider, nor for use of the Application contrary to these Terms or to the warning in section 8.

12. Termination

If you breach these Terms, we may restrict or block your access to the Application. Before we do so, we will warn you and give you the reason — unless immediate action is necessary for the safety of users or to comply with a legal obligation, in which case we will give the reason promptly after blocking. You may appeal our decision by writing to support@gryndapp.com — if the appeal is justified, we will restore your access. Blocking for breach of these Terms does not entitle you to a refund of the fee for the current billing period. Blocking your account does not cancel an active subscription — you cancel it yourself 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, you nevertheless keep the protection of the mandatory provisions of the law of your country of habitual residence, and you may bring your case before the court of your place of residence. You may also use out-of-court dispute resolution — in Poland such procedures are run by, among others, the regional inspectorates of the Trade Inspection (Inspekcja Handlowa) and the permanent consumer arbitration courts, and a list of accredited bodies across the European Union is available at consumer-redress.ec.europa.eu. Using this route is voluntary.
