General Terms and Conditions (Terms)

1. Scope

These General Terms and Conditions (Terms) apply to the use of the web application hammhamm.app (hereinafter "Application"), operated by Jonas Hamm, Eschenahornhof 1, 21149 Hamburg, Germany, e-mail: info@jonashamm.de (hereinafter "operator").
Deviating terms of the user are not recognized unless the operator expressly agrees to their validity in writing.

2. Subject matter of the contract

The Application enables registered users to save and manage recipes, calculate nutritional values, create weekly meal plans, and use other features offered.
The exact scope of features is set out in the respective description of services on hammhamm.app.

3. Registration and user account

  1. Use of the Application requires registration.

  2. The data provided during registration must be truthful and complete.

  3. The user is obligated to keep their login credentials secret and not to disclose them to third parties.

4. Services and availability

  1. The operator provides the Application with its respective current scope of features.

  2. There is no entitlement to any particular availability, although the operator strives for the most uninterrupted use possible.

  3. The operator may modify, expand or discontinue features, provided this is reasonable for the user.

5. Costs and payment terms

  1. Use of the Application may be free of charge or subject to a fee. Details on prices and billing periods can be found on the pricing page of hammhamm.app.

  2. Fee-based services are due in advance.

  3. All prices include the applicable statutory value-added tax.

6. User obligations

  1. The user may not use the Application for unlawful purposes.

  2. It is prohibited to post content that violates applicable law, public morals, or the rights of third parties (e.g. copyright, trademark or personality rights).

  3. In the event of violations, the operator is entitled to suspend or delete the user account.

7. User content

  1. Recipes, images, texts and other content are entered by the users themselves or imported from sources they specify ("user content"). The operator does not review user content in advance and does not adopt it as its own.

  2. Users are solely responsible for their content and ensure that they hold the necessary rights, in particular when marking recipes as public or sharing them with others.

  3. The user grants the operator the simple, geographically unlimited right to store and process their content within the Application (e.g. nutrition calculation, ingredient matching) and, where the user chooses so, to display it to other users or publicly. This right ends when the content or the account is deleted.

  4. The operator gives no warranty regarding the accuracy, completeness, currency or tolerability of other users' content. Unlawful or incorrect content can be reported via "Report recipe" or by e-mail to the operator; the operator may remove such content.

8. Nutrition, health and AI-generated content

  1. Nutrition values are calculated automatically from public databases (including USDA FoodData Central, Open Food Facts, the German Bundeslebensmittelschlüssel). They are computed estimates and may deviate from the actual values.

  2. The Application, including the calorie calculator, food diary and nutrition assistant, does not constitute and does not replace medical, dietary or nutritional therapy advice. In case of health questions, illnesses, pregnancy, allergies or eating disorders, consult a professional.

  3. Allergen and intolerance information is based on user input and automatic matching and may be incomplete. Users check ingredients on their own responsibility.

  4. Parts of the Application use artificial intelligence, for example to recognise ingredients, to create recipes from text input, for the assistant and to generate recipe images. AI-generated images are labelled as such. AI-generated content may contain errors and must be checked by the user before use.

9. Liability

  1. The operator is liable for damages only in cases of intent or gross negligence.

  2. For slight negligence, the operator is liable only for breach of material contractual obligations (cardinal obligations).

  3. Liability is limited to the foreseeable damage typical for this type of contract.

  4. Liability for data loss is only assumed if the user has carried out proper data backups.

  5. The operator is not liable for other users' content or for damages resulting from the use of nutrition values, dietary recommendations or AI-generated content, unless the operator acted with intent or gross negligence. Liability for injury to life, body or health and under the Product Liability Act remains unaffected.

10. Termination

  1. The user may delete their account at any time in the settings. This deletes their content and personal data; recipes that other users shared with them remain with those users.

  2. The operator may terminate the usage relationship with 14 days' notice.

  3. The right to extraordinary termination for good cause remains unaffected.

11. Data protection

The collection, processing and use of personal data is carried out exclusively in accordance with the Privacy Policy of hammhamm.app.

12. Changes to these Terms

The operator reserves the right to amend these Terms with effect for the future. Users will be informed of material changes at least 30 days before they take effect and asked to accept them at their next login. Users who object may delete their account; continued use requires acceptance.
