1. Acceptance of these Terms
These Terms and Conditions ("Terms") govern the use of Protelino (the "App"), a nutrition and metabolic-diet tracking application. By downloading, accessing, or using the App, the user agrees to be bound by these Terms.
2. Description of the Service
Protelino is a self-management tool that helps individuals with metabolic conditions such as PKU, MSUD, Tyrosinemia Type 1, Homocystinuria, and Isovaleric Acidemia track dietary nutrient intake, log meals, monitor blood lab results, and manage related information. The App calculates estimated nutrient values based on food databases, user input, and, for certain features, AI-assisted image analysis. The App is a tracking and organizational tool only. Certain features, such as the catalog of region-specific medical food products, may vary or be unavailable depending on the user's selected region or country. Subject to compliance with these Terms, the Developer grants each user a limited, non-exclusive, non-transferable, non-sublicensable license to download, install, and use the App on a device the user owns or controls, solely for personal, non-commercial use.
3. Eligibility and Account Requirements
Use of the App, including creation of an account, is restricted to individuals who are at least 18 years old or the age of legal majority in their jurisdiction, whichever is higher. An account holder may create and manage additional profiles within the App on behalf of family members, including minors, for whom the account holder is a parent or legal guardian. The App does not knowingly permit a minor to independently register or control an account. If it comes to the Developer's attention that an account has been created by a minor without the involvement of a parent or legal guardian, the Developer reserves the right to suspend or terminate that account.
4. Medical Disclaimer
Protelino is not a medical device, is not intended to diagnose, treat, cure, or prevent any disease or condition, and is not a substitute for professional medical or dietetic advice, diagnosis, or treatment. All nutrient values, calculated estimates, targets, and any information generated by the App's food-recognition or estimation features are approximations, not guarantees: the App's AI-assisted food recognition (AI Scan) feature in particular can misidentify a food or return an inaccurate result, the same way any automated system can make mistakes, and none of this information may ever be relied upon as the sole basis for a dietary or medical decision. Users must always consult a qualified metabolic specialist, physician, or registered dietitian before making changes to a treatment plan, diet, or medication, and must follow their care team's guidance in all cases of conflict with information shown in the App. The Developer is not a healthcare provider and does not provide medical services through the App.
5. Accuracy of Data and Third-Party Sources
Food and nutrient data displayed in the App originates from a combination of licensed and publicly available reference databases (including the German Bundeslebensmittelschlüssel and Open Food Facts), manually curated entries, user-entered custom foods, and, where applicable, AI-assisted estimates generated from photographs. While reasonable efforts are made to keep this data accurate and current, the Developer does not warrant that any value is complete, accurate, or up to date, and disclaims all responsibility for decisions made in reliance on it. Users should verify nutrient information against a product's own packaging or label whenever accuracy is critical. The App's low-protein and specialty-food product catalog (including brands such as Loprofin, Vitaflo, Promin, Nutricia, Mevalia, Harifen, and others) is provided for informational purposes only. The Developer has no business relationship, sponsorship, endorsement, or other affiliation with any of these brands or their manufacturers, and neither the Developer nor the respective brand is responsible for the completeness, accuracy, or current validity of the product data shown, including nutrient values, formulation, availability, or packaging, any of which may change without notice.
6. Account Registration and Security
Users are responsible for maintaining the confidentiality of their account credentials and for all activity that occurs under their account. Users must provide accurate information when creating an account and when entering profile, meal, and lab-value data, and are solely responsible for the accuracy of any data they enter. Any suspected unauthorized use of an account must be reported to the Developer without undue delay.
7. Subscriptions and Payments
Protelino Pro is an auto-renewing subscription billed through the Apple App Store or Google Play Store, at the price and billing interval (monthly or annual) shown prior to purchase. Payment is charged to the user's Apple ID or Google Play account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the then-current billing period. Subscriptions must be managed or cancelled through the user's Apple ID or Google Play account settings, not within the App. Refunds are subject to the refund policies of Apple or Google, as applicable, and are not processed directly by the Developer. Prices may vary by region due to taxes and platform-specific currency conversion.
8. Acceptable Use
Users agree not to: (a) use the App for any unlawful purpose; (b) attempt to reverse-engineer, decompile, or extract the source code of the App except as permitted by applicable law; (c) interfere with or disrupt the App's servers or networks; (d) misrepresent their identity or impersonate another person; (e) use the App to store or transmit unlawful, defamatory, or infringing content; or (f) access or use the App from a country subject to a U.S. Government embargo, or while listed on any U.S. Government list of prohibited or restricted parties. The Developer reserves the right to suspend or terminate access for any user who violates this section.
9. Intellectual Property
The App, including its design, source code, trademarks, and original content, is the property of the Developer and is protected by applicable intellectual property laws. Nutrient and food data sourced from third parties remains the property of the respective data providers, as described in the App's Credits & Data Sources section. Users retain ownership of the personal data and content they enter into the App, subject to the license granted to the Developer to process that data as described in the Privacy Policy solely to provide the App's functionality. If a user submits feedback, suggestions, or ideas about the App to the Developer, the user grants the Developer a perpetual, irrevocable, worldwide, royalty-free license to use that feedback for any purpose, including improving the App, without any obligation to compensate or attribute the user.
10. Third-Party Services
The App relies on third-party service providers, including but not limited to Supabase (backend infrastructure), RevenueCat (subscription management), Google (AI-assisted food recognition via the Gemini API), Open Food Facts (public food database), and the platform operators Apple and Google (app distribution and payment processing). Use of the App is also subject to the applicable terms of these third-party providers. Apple Inc. and Google LLC are third-party beneficiaries of these Terms with respect to their respective platforms and have no obligation to furnish any maintenance or support services for the App. As between the Developer and Apple, the Developer is solely responsible for the App, its content, and any product-related or intellectual-property claims concerning it. Users must also comply with any applicable third-party agreements (for example, a wireless data service agreement) when using the App.
11. Disclaimer of Warranties
The App is provided "as is" and "as available," without warranties of any kind, whether express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, non-infringement, or that the App will be uninterrupted, secure, or error-free, to the fullest extent permitted by applicable law. Where the App is obtained through the Apple App Store, Apple has no warranty obligation whatsoever with respect to the App, and any claim that the App fails to conform to an applicable warranty is the Developer's sole responsibility, subject to a refund of the purchase price where required by law.
12. Limitation of Liability
To the fullest extent permitted by applicable law, the Developer's liability for damages is limited to cases of intent and gross negligence. In cases of ordinary negligence, the Developer is liable only for the breach of a material contractual obligation (a duty whose fulfillment is essential to the proper performance of the contract and on which the user may regularly rely), and in such cases liability is limited to the type of damage that was foreseeable at the time the contract was entered into. This limitation does not apply to liability for injury to life, body, or health, or to any liability under mandatory statutory provisions, including product liability law, which cannot be limited or excluded.
13. Indemnification
Users agree to indemnify and hold the Developer harmless from any claims, damages, or expenses (including reasonable legal fees) arising from their misuse of the App or violation of these Terms, except where such claims arise from the Developer's own intent or gross negligence.
14. Term and Termination
These Terms remain in effect for as long as a user continues to use the App. A user may stop using the App and delete their account at any time through the App's settings or by contacting the Developer. The Developer may suspend or terminate a user's access for violation of these Terms or applicable law, or discontinue the App, with reasonable notice where required by applicable law.
15. Governing Law and Dispute Resolution
These Terms are governed by the laws of the Federal Republic of Germany, excluding its conflict-of-law rules and the United Nations Convention on Contracts for the International Sale of Goods. Where the user is a consumer habitually resident in another EU/EEA member state, this choice of law does not deprive the user of the protection afforded by the mandatory consumer-protection provisions of that state's law. The European Commission provides an online dispute resolution platform at https://ec.europa.eu/consumers/odr, which users may use to resolve disputes. The Developer is not obliged and does not commit to participate in dispute resolution proceedings before a consumer arbitration board.
16. Changes to These Terms
These Terms may be updated from time to time. Material changes will be indicated by an updated "Last updated" date, and, where required by law, users will be notified through the App. Continued use of the App after a change takes effect constitutes acceptance of the revised Terms.
17. Severability and Entire Agreement
If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions remain in full force and effect, and the invalid provision will be replaced by a valid provision that most closely reflects its original intent. These Terms, together with the Privacy Policy, constitute the entire agreement between the user and the Developer regarding use of the App. The Developer may assign or transfer these Terms, in whole or in part, in connection with a merger, acquisition, corporate reorganization, or sale of all or substantially all of its assets; a user may not assign these Terms without the Developer's prior written consent.
