These terms set out the rules for using the Grzybiarz mobile app and website (the “App”). The service provider is [entity name / sole proprietorship], [address], tax ID [___], email: kontakt@grzybiarz.app. (To be completed before publication.) Using the App means accepting these terms.

Grzybiarz is an informational and assistive tool that supports searching for and identifying mushrooms. It provides probabilistic suggestions (calibrated confidence, a list of the most likely species, comparison with toxic species). The App does not constitute mycological advice, an expert opinion, or a guarantee of edibility, and must not be the sole basis for a decision to pick or consume a mushroom.

The final decision to pick, possess, and consume any mushroom rests solely with the user and is made at the user’s own responsibility, based on their own knowledge and experience. A result shown by the App is only one of the inputs and never replaces the user’s own assessment. In case of any doubt, the user should have the mushroom verified by an expert, a mushroom inspector or classifier (e.g., at a sanitary-epidemiological station), and should not consume a mushroom identified solely by the App. Some species are deadly even in small amounts, and symptoms of poisoning may be delayed.

The App is provided on an “as available” basis. To the extent permitted by law, the provider does not warrant that recognitions and detections are complete, error-free, or current, this follows from the probabilistic nature of machine-learning models.

The above provisions do not exclude or limit the provider’s liability to the extent that, under mandatory provisions of law, it cannot be excluded or limited, in particular liability toward a consumer for personal injury (Art. 385(3)(1) of the Polish Civil Code) and liability for damage caused intentionally (Art. 473 § 2 of the Polish Civil Code). Provisions less favourable to a consumer than mandatory law are, to that extent, ineffective, and those provisions of law apply instead.

The App, its software, educational content, species atlas, graphics, and trademarks are protected by law and remain the property of the provider or its licensors. Using the App does not transfer to the user any rights other than the right to use it in accordance with these terms.

The provider may change these terms for important reasons, such as a change in the App’s features or in the law. We will give advance notice of material changes. Continued use of the App after the changes take effect means accepting them.

Matters not covered by these terms are governed by Polish law; this does not deprive a consumer of the protection afforded by mandatory provisions. Contact: kontakt@grzybiarz.app.
