One L1fe

Terms of Service

Last updated 28 August 2026
These are the terms that will apply once the One L1fe app is publicly available. The app is currently in private build; today this website only runs the waiting list described in our privacy notice. These terms are published in advance so they are ready at launch.

1. Who we are

One L1fe is operated by One L1fe, Nørrebro Vænge 2, 2200 Copenhagen, 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 and forms part of this agreement.

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

2. What One L1fe is, and is not

One L1fe builds a digital twin of your health from the data you connect, wearables, blood biomarkers, and what you tell us, and turns it into personalised 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, predict 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, including 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.

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, and we encourage you to check anything significant with a qualified professional.

4. Your account

Keep your login credentials confidential, 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. Nothing is imported without your authorisation, and you can disconnect any source at any time. You confirm that the data you connect relates to you and that you have the right to provide it, do not upload another person's health or lab data.

Wearables, labs and testing services are independent third parties with their own terms. We are not responsible for the accuracy or availability of their data, and not liable if one of them changes or ends its integration.

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 the 14 day right of withdrawal, will apply.

7. Your data

You own your data. You grant us a limited, non exclusive, royalty free licence to host, store, process and display it solely to provide the Service to you, as described in our Privacy Policy. The licence ends when you delete the data or your account. It does not allow us to use your data for advertising, to sell it, or to train general purpose AI models.

If you send us feedback or feature suggestions, we may use them freely to improve the Service.

8. Acceptable use

Do not: use the Service unlawfully; upload another person's health or lab data; 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 terminate 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. Availability

We aim to keep the Service available but do not guarantee uninterrupted access, and may suspend it for maintenance. The Service is provided with the quality you can reasonably expect under EU rules on digital content and services; if it does not conform, you have the remedies available under Danish consumer law.

10. Ending the agreement

You can delete your account at any time from settings; your data is then deleted as set out in the Privacy Policy.

We may terminate or suspend your account for material breach, where legally required, or if we discontinue the Service. Except for serious breach, we will give at least 30 days' notice and time to export your data before access ends.

11. Changes to these terms

We may amend these terms where there is a valid reason, a change in law, a new feature, or security requirements, and we will notify you by email at least 30 days before a material change takes effect. Changes are never retroactive, and anything requiring your consent under data protection law is handled by a separate consent request, not through these terms.

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 and the Privacy Policy are the whole agreement between us about the Service.
