Legal Information

Last updated: 9 September 2026

Medical & AI Disclaimer

Not Medical Advice: The Chuw application ("the App") is for informational and wellness purposes only and is not a medical device. It is not a substitute for professional medical advice, diagnosis, or treatment.

AI Limitations & Allergens: The App uses Artificial Intelligence (AI) to analyze labels. AI systems can make errors or "hallucinate" information, and may fail to detect specific ingredients, including severe allergens (such as peanuts, gluten, dairy, soy). Never rely on the App for allergies. Always read the physical product label before consuming any food.

Acceptable Use Policy (AUP)

Prohibited Content (No PII): You are strictly prohibited from uploading images containing Personally Identifiable Information (PII), such as human faces, shipping labels with addresses, or prescription medication labels.

Prohibited Conduct: You agree not to use the App to: (1) reverse-engineer the source code or AI system prompts; (2) scrape data using bots; or (3) train a competing AI model.

Terms and Conditions

Age Requirement: You must be at least 16 years old to use this App and to consent to the processing of your data.

Account: You can create an account with an email and password, or via "Sign in with Google" (and, where available, Apple). You are responsible for keeping your credentials secure and for activity under your account.

Subscriptions & Billing: Chuw offers a free plan and a paid Premium plan. When the limited launch offer is enabled, a new account first receives 7 days of Premium from account creation, with no card and no automatic charge. The separate paid monthly and annual plan begins with a 14-day free trial; after that it renews automatically at the price shown until you cancel. You can cancel anytime and keep Premium until the end of the period you have already paid for. Payments on the website are processed by our payment provider (Creem), including iDEAL and card; VAT is included. Purchases made through an app store (e.g. Google Play) are governed by that store's terms and refund policy. A one-time annual option without auto-renewal is also available.

Liability: To the maximum extent permitted by law, Chuw shall not be liable for any direct or consequential damages (including allergic reactions) arising from the use of the App, except in cases of intent or gross negligence.

Changes: We may update these terms from time to time. The date at the top reflects the last change. For material changes we will notify you where reasonably possible; continued use of the App constitutes acceptance.

Governing Law: These terms are governed by the laws of the Netherlands.

Privacy Policy (GDPR)

Data Controller & Contact: Chuw is the controller of your data. For privacy inquiries, access, or deletion requests, contact us at hello@chuw.app or via the feedback function in the App.

Data We Process: (1) Account data — your email address, and if you sign in with Google or Apple, the name and email that provider shares with us; (2) Health focuses you select; (3) Scans — product photos/label text you submit via the camera or gallery, and the resulting scores and history; (4) Feedback you send us; (5) Subscription status (no card details — those are handled by our payment provider); (6) privacy-minimal product analytics — pseudonymous event names, platform, timestamp, and coarse scan outcome, without product, ingredient, or health data; (7) content-free technical error signals — a normalized error type, app surface, platform, release, environment, and timestamp, without error messages, stack traces, URLs, scan content, health data, or account IDs.

Camera & Photos: The camera is used solely to capture products and labels for analysis. With your explicit permission, the product photo and selected health focuses are sent to an AI processing service for analysis. Chuw deletes scanned images immediately after analysis and does not use them to train AI models.

Sub-processors: We share data only with the service providers needed to run the App: Supabase (database, authentication, and hosting, EU); OpenRouter (routes label text and health focuses to AI models, including Google Gemini, for analysis); Creem (payment processing on the website); RevenueCat (subscription management for the Android and iOS apps' in-app purchases); Resend (email delivery); Sentry (technical error reporting using content-free error signals only); and Google (Sign in with Google, and Google Play for the Android app). If you use the iOS app, sign in with Apple, or purchase Premium through the App Store, Apple acts as a sub-processor.

Open Food Facts: For barcode lookups, the App may retrieve product information from Open Food Facts. The Open Food Facts database is available under the Open Database License (ODbL) and Open Food Facts and its contributors retain applicable rights in the contents.

Product analytics: We use a first-party, privacy-minimal analytics table to understand where scans succeed or fail and whether users return. It contains no barcode, product name, ingredients, photo, or health focus. The table uses a pseudonym instead of your account ID, is accessible only to Chuw, and is not used for advertising.

Legal Bases: Your health focuses are special-category data, processed based on your explicit consent (Art. 9 GDPR); providing the App and subscription is based on performance of the contract; security and app reliability are based on legitimate interest.

International Transfers: Your database is hosted in the EU (via Supabase). Text processing by AI providers may occur outside the EU under appropriate safeguards (such as the EU-US Data Privacy Framework or Standard Contractual Clauses).

Retention: Scanned images are deleted immediately after analysis. Your account and scan data are kept until you delete them or your account. Privacy-minimal product analytics are kept for a maximum of 180 days. To prevent abuse of the limited-time Premium offer, after account deletion we retain for no more than 24 months only an irreversible HMAC claim of the normalized email address — never the email itself, account ID, device, or IP address.

Your Rights: You have the right to access, rectify, delete, port, and object to the processing of your data, and to withdraw consent. You also have the right to lodge a complaint with your local Data Protection Authority.

Delete Your Account & Data

If you have the App installed: go to Settings → Security → Delete Account. This permanently deletes your account and all associated data (scans, health focuses, subscription status) immediately. Only the anonymized HMAC claim described above may remain for up to 24 months for abuse prevention.

If you no longer have the App: email hello@chuw.app from the address associated with your account and request deletion. We process this request within 30 days (the statutory GDPR deadline).

Local Storage: On iOS and Android, the App stores your authentication session in secure device storage. Functional local storage is used only for preferences and temporary app state. We do not use third-party advertising or tracking cookies.
