Yolo Terms of Use

These terms are a contract between you and dataWorks GmbH, Seestrasse 59, 8702 Zollikon, Switzerland, UID CHE-196.074.218 ("Yolo", "we") governing your use of the Yolo mobile app and related services. By creating an account or using the app you accept them.

Yolo is not a medical service. Nutrition scores, health reports, AI analyses and experiment results are informational tools for personal insight. They are not medical advice, diagnosis or treatment, and they are no substitute for a doctor, dietitian or other qualified health professional. You remain responsible for your own health and the decisions you make about it. Never disregard professional advice or delay seeking it because of something Yolo showed you. If you have a health issue or pre-existing condition — including an eating disorder, diabetes, or any condition affected by diet — always talk to your doctor first.

1. The service

Yolo is a nutrition and health tracking app: you log meals (manually, by barcode, photo or voice), and Yolo computes nutrient intakes, personalised targets and a nutrition score, optionally combines them with health metrics you share from Apple Health or Health Connect, and generates reports and insights, some of them AI-assisted.

2. Eligibility & your account

• You must be at least 16 years old.
• You sign in with your phone number. Keep access to that number secure; you are responsible for activity under your account.
• One account per person; accounts are personal and non-transferable.

3. Accuracy, reference values & methodology

• Food values are typical values, not guarantees. Nutrient values come from lab-tested official food databases and, for packaged products, Open Food Facts. Even laboratory-analysed values are averages: the food on your plate varies with where it was grown, how it was processed, stored and prepared. Values estimated from photos, voice or text descriptions carry additional uncertainty. We do not guarantee that any displayed value matches what you actually eat.
• AI can make mistakes. Food recognition and meal analysis are best-effort estimates. Review results before relying on them — every entry can be corrected.
• Reference values blend official guidance with current science. The nutrition score compares your intake against reference values we derive, to the best of our knowledge, from official dietary recommendations and recent scientific research. Official recommendations differ between countries and regions; where well-supported current evidence is more up to date than official guidance, we follow the evidence. The scoring method is refined as research evolves, so your score can change over time even if your data does not.
• Not a clinical assessment. Scores and targets are personalised estimates built on population reference values and the profile data you provide — they are not medical measurements.

4. Subscriptions

• Premium features require a paid subscription (weekly, monthly or annual), purchased through the Apple App Store or Google Play.
• Auto-renewal: subscriptions renew automatically at the end of each period unless you cancel at least 24 hours before renewal, in your App Store or Google Play subscription settings. Deleting the app does not cancel a subscription.
• Free trials: where offered, the trial converts into a paid subscription unless cancelled before the trial ends. One trial per user across all plans.
• Prices: shown in the app before purchase; price changes apply from the following renewal and are announced in advance through the store.
• Refunds: handled by Apple or Google under their policies, as we do not process payments ourselves. Statutory rights remain unaffected.
• Promo codes: promotional offers can be limited in number and time and carry their own conditions; abuse (e.g. automated redemption) voids them.

5. Your content

Meal photos, voice recordings and other content you submit remain yours. You grant us the limited right to process them for the sole purpose of providing the service to you (e.g. sending a meal photo to the AI model you asked to analyse it). We claim no other rights to your content. See the Privacy Policy for how it is protected and how long it is kept.

6. Fair use

You agree not to:

• reverse engineer, scrape, or access the service by any means other than the app;
• abuse AI features through automated, excessive or manipulated requests;
• upload content that is unlawful or infringes others' rights;
• circumvent subscription gating or attest a modified app build.

We may apply reasonable technical limits (e.g. rate limits on AI analyses) to keep the service available for everyone.

7. Intellectual property

The app, its design, databases, scoring methodology and content (excluding your content and third-party databases) are owned by us or our licensors and protected by law. We grant you a personal, non-exclusive, non-transferable licence to use the app on devices you own, for personal, non-commercial purposes.

8. Availability & changes to the service

We work to keep Yolo available and accurate, but the service is provided without guarantee of uninterrupted availability. We may modify, add or remove features; if a change materially reduces a paid feature you have already bought, you may cancel and receive a pro-rated refund via the store where permitted.

9. Warranty & liability

To the extent permitted by law: the service is provided "as is"; we are liable without limit for intent and gross negligence, and for injury to life, body or health, but for slight negligence only for breach of essential contractual duties and limited to typical, foreseeable damage. We are not liable for decisions you make based on informational output of the app (see the health disclaimer above). Mandatory statutory liability — including under product liability law — remains unaffected.

10. Termination

You can stop using Yolo and delete your account at any time (Settings → Delete Account, or via the web). We may suspend or terminate accounts that materially breach these terms; where reasonable, we will warn you first. Paid periods already started are governed by the store's refund rules.

11. App-store terms

Your download is also subject to the Apple Media Services Terms or Google Play Terms of Service. Apple and Google are not parties to these terms and have no obligation to provide support or maintenance for Yolo. Where required by Apple's Instructions for Minimum Terms, Apple is a third-party beneficiary of this licence and may enforce it against you.

12. Changes to these terms

We may update these terms. For material changes we will notify you in the app at least 30 days before they take effect; continued use after that date constitutes acceptance. If you do not agree, stop using the service and delete your account before the change takes effect.

13. Severability

If a provision of these terms is held invalid, the remainder stays in force; the invalid provision is replaced by the lawful provision closest to its economic intent.

14. Governing law

These terms are governed by Swiss law, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. Place of jurisdiction is Zollikon, Switzerland; mandatory consumer-protection forums in your country of residence remain available to you.
