One L1fe

Privacy Policy

Last updated 28 August 2026
This is the privacy policy that will apply to the One L1fe app once it is publicly available. The app is currently in private build; nothing described here is happening yet. For what this website collects today, see the website privacy notice. Some details below, marked as such, are not decided yet and will be filled in here before they apply to anyone.

1. Who is responsible for your data

One L1fe is operated by One L1fe, Nørrebro Vænge 2, 2200 Copenhagen, Denmark. We are the data controller for the personal data described in this policy.

Questions or requests: privacy@one-l1fe.com

Other health testing you choose to addResults and derived metrics from the provider

We collect automatically: IP address, device type, operating system, app version, features used, timestamps, errors and crash reports. Website cookies are covered in section 8.

3. Health data and your consent

Most of what makes One L1fe useful is data about your body. Under Article 9 GDPR, health data is a special category and gets stronger protection.

Our legal basis is your explicit consent, under Article 9(2)(a) GDPR. In practice:

4. Where your data is stored

Your health data is stored and processed on servers we operate through our cloud provider. It is not kept only on your device. Server side processing is what lets the coach combine sources, track change over time, and generate personalised insight. Some processing happens outside the EU/EEA, as described in section 7.

Not decided yet: the specific storage region. This section will name it once infrastructure for the app is chosen.

5. Why we process it, and on what basis

PurposeLegal basis
Create and run your accountContract, Art. 6(1)(b)
Import, store and display your health data; generate insights and coachingExplicit consent, Art. 6(1)(a) and 9(2)(a)
Provide supportContract, Art. 6(1)(b)
Security, fraud prevention, fault diagnosis, aggregated product analyticsLegitimate interests, Art. 6(1)(f)
Marketing emails and product updatesConsent, Art. 6(1)(a), and section 10 of the Danish Marketing Practices Act

Where we rely on legitimate interests, we have weighed our interest against your rights, and you can object (section 9).

We do not use your health data to train general purpose AI models, and our AI providers are contractually barred from doing so.

6. Who else processes your data

Any provider listed here processes data on our behalf under an Article 28 data processing agreement. We do not sell your data and do not share it with advertisers.

Not decided yet: the specific cloud host, AI model provider, email sender and analytics tool the app will use. This section will name each one, and where it operates, before it processes any of your data, not after.

We may also disclose data to public authorities where legally required, or in a merger or acquisition, in which case we notify you in advance so you can delete your account first if you prefer.

The AI coach. When you use it, you are interacting with an AI system, not a person. To answer, we send your question and the metrics needed for it to our model provider, the minimum for that request, not your full record. Our contract will require that your data is used only to respond to you, is not used for training, and is retained by the provider only briefly or not at all. We keep your conversation history so the coach has context and you can look back; you can delete it at any time. We do not make solely automated decisions with legal or similarly significant effects under Article 22, the coach suggests, you decide.

7. Transfers outside the EU/EEA

Some providers may process data outside the EU/EEA, including in the United States. Where they do, we rely on an adequacy decision (including the EU/US Data Privacy Framework where applicable) or on the European Commission's Standard Contractual Clauses with appropriate safeguards. Email us for a copy of the safeguards for any specific transfer.

8. Cookies

One L1fe uses only cookies and similar technology strictly necessary for it to work, such as keeping you signed in. We use no advertising cookies, tracking pixels or third party analytics, so there is no consent banner.

9. Your rights

You have the right to access your data, have it corrected or deleted, restrict or object to processing, receive it in a portable format, and withdraw consent at any time. You can object to direct marketing at any time with no reason given, and we will stop.

Email privacy@one-l1fe.com. We respond within one month, and will tell you within that month if a complex request needs longer. It is free. We may need to verify your identity first, particularly for health data. A full export will be available from your account settings.

10. Security

We use encryption in transit and at rest, access controls limiting staff access to what a task requires, multi factor authentication on administrative systems, access logging, and tested backups.

No system is perfectly secure. If a breach occurs we will notify Datatilsynet within 72 hours where Article 33 requires it, and notify you directly without undue delay where the breach is likely to be a high risk to you.

11. How long we keep it

DataRetention
Account, profile and health dataWhile your account is open; deleted within 30 days of account deletion or withdrawal of consent
Coach conversation historyUntil you delete it, or 30 days after account deletion
Waiting list emailsUntil you unsubscribe, or 18 months from signup if we have not launched
Security and access logs12 months
Support correspondence24 months after the case closes

Genuinely anonymised aggregate statistics, which cannot be linked back to you, may be kept indefinitely.

12. Changes

We may update this policy as the product develops; the date at the top shows the current version. For material changes, a new category of data, a new purpose, a new provider handling health data, or a change of controller, we notify you by email or in the app before it takes effect. Where a change needs your consent, we ask for it separately rather than treating continued use as agreement.
