One L1fe

Terms of Service

Last updated 30 October 2026

1. Who we are

One L1fe is operated by One L1fe ApS (CVR 46866193), Nørrebro Vænge 2, 1. th, 2200 Copenhagen N, Denmark. Contact: hello@one-l1fe.com.

These terms cover your use of one-l1fe.com, the One L1fe apps and everything we provide through them (the "Service"). Creating an account means you accept them. Our Privacy Policy explains how we handle your data. It is a notice, not part of what you agree to.

Nothing here limits your mandatory rights as a consumer under Danish or EU law.

2. What One L1fe is, and is not

One L1fe brings the data you connect (wearable readings, lab values, test reports and what you tell us) together in one overview of your health and fitness, which the app calls your Digital Twin, and turns it into personalized coaching, insight and trends over time. It is a wellness and coaching tool.

It is not a medical device and is not intended for any medical purpose. It does not diagnose, prevent, monitor or treat any disease, injury or disability, and it is not a substitute for professional medical advice.

The Service may be inaccurate where your physiology differs from population averages, for example because of a condition, pregnancy, medication or age. If you are pregnant, have a diagnosed condition or are under medical supervision, talk to your doctor before acting on what the Service suggests.

3. The AI coach

Parts of the Service use artificial intelligence. When you use the coach, you are interacting with an AI system, not a person. It uses third-party AI models reached through our server; the Privacy Policy describes the provider and says what is sent. The same models read the reports, photos, labels, barcodes and food names you hand the app, prepare cards and review plans. None of this happens until you agree to it in the app, and you can withdraw that at any time in Settings, under Account.

Its output is generated automatically and can contain errors, omissions or confident sounding statements that are wrong. It is not medical advice and section 2 applies in full. You decide how to act on it; check anything significant with a qualified professional. If a reply looks wrong or harmful, report it from the reply itself.

4. Your account

You must be 18 or older to create an account, and you need one to use the app. Keep your login credentials confidential, because you are responsible for activity under your account. Tell us at hello@one-l1fe.com if you think it has been compromised. Give accurate profile information: inaccurate age, sex or weight produces inaccurate insight.

5. Connecting your data

You choose what to connect: your phone's health service, a wearable account (Garmin, WHOOP, Polar or Oura) that you sign in to from the app, or a file you hand the app. Nothing is imported without your permission. You can withdraw it at any time, for the health service in your phone's settings, and for a wearable account under Apps and wearables in the app, which also removes what that account sent. You confirm that the data you connect is yours to provide.

Wearable makers, labs and testing services are independent third parties with their own terms. We are not responsible for the accuracy or availability of their data, or if one of them changes or ends its service. Where such a service sets rules for how its data may be used, we follow them.

6. Price

The Service is currently free. If we introduce paid plans, we will publish the pricing and payment terms before you are asked to pay anything, and your statutory rights as an EU consumer, including any right of withdrawal, will apply.

7. Your data

You own your data. You grant us a limited, non-exclusive, royalty-free license to host, store, process and display it solely to provide, maintain and secure the Service, as described in our Privacy Policy. The license ends when the data is deleted. It does not allow us to sell your data or use it for advertising, and it does not allow us or anyone else to train AI models on it, apart from the misuse filters described in the Privacy Policy.

The app, the website and their content belong to One L1fe ApS. You may use what the Service gives you, including AI output, for your own purposes; we do not promise that it is correct (section 3). If you send us feedback or suggestions, we may use them freely to improve the Service.

8. Acceptable use

Do not: use the Service unlawfully; reverse engineer it except where EU law permits; probe or test its security other than by responsible disclosure to security@one-l1fe.com; scrape it or access it by automated means outside our published interfaces; share your account; present its output to others as medical advice; or use the coach to generate unlawful or harmful content.

We may suspend or end an account for breach. Unless a serious breach makes it impossible, we will tell you why and give you a chance to fix it first.

9. Changes and ending

We aim to keep the Service available but do not guarantee uninterrupted access. It has the quality you can reasonably expect under EU rules on digital content and services; if it does not, you have the remedies available under Danish consumer law. We are not responsible for failures outside our reasonable control, including a provider changing or ending its service.

We may change the Service or these terms for a valid reason, such as a change in law, technology, security requirements or the terms of a provider we rely on. We notify you by email at least 30 days before a change to your disadvantage takes effect, unless the law or a provider requires it sooner, and you may end the agreement free of charge before it applies. Changes are never retroactive. Anything that needs your consent under data protection law gets a separate consent request.

You can end this agreement at any time under Settings, Account, Delete account, or by writing to privacy@one-l1fe.com from the address you signed up with. Your data is then deleted as set out in the Privacy Policy.

We may end or suspend your account for material breach, where the law requires it, or if we discontinue the Service. Except for serious breach, or where security, the law or a provider requires faster action, we give at least 30 days' notice and a copy of your data on request before access ends.

10. Our liability

Nothing in these terms limits our liability for loss we cause intentionally or through gross negligence, for death or personal injury caused by our negligence, for breaches of data protection law (Article 82 GDPR), or for anything else that mandatory law, including consumer protection and product liability law, does not allow us to limit.

Otherwise we are not liable for indirect or consequential loss, or for decisions you take on the basis of the Service or its AI output (sections 2 and 3). While the Service is free, our total liability to you is limited to DKK 2,000. If you pay for the Service, it is limited to what you paid us in the 12 months before the claim.

11. Law and disputes

These terms are governed by Danish law. If you live in another EU country, you keep the protection of the mandatory consumer law of the country where you live. If something goes wrong, write to us first at hello@one-l1fe.com. You can also complain to the Danish consumer complaints body, Nævnenes Hus, or bring a case before the courts where you live.

12. General

If any provision is invalid, the rest stands. Not enforcing a right once does not waive it. You may not transfer your rights without our consent; we may assign these terms in a merger or acquisition, provided your rights are not reduced. These terms are the whole agreement between us about the Service.
