Privacy Policy

Last updated : 12 November 2026

Uknno is an AI chat that reads the data from your sports watch and helps you train. That data is personal and, in part, health data. This page explains what we collect, why, who sees it, and how you stay in control.

1. Who is responsible

The data controller is MANGALLON Léonard, a French sole proprietor (entreprise individuelle, SIREN 106 872 799), operating Uknno. Contact for anything about your data: hello@uknno.com. We are not required to appoint a Data Protection Officer; this address reaches the person who answers for the data.

2. What we collect and why

Messages you send to usReply to you and handle your requestsLegitimate interest / contract

We never receive your card number: payments are handled by Stripe. We do not sell your data, we do not use it for advertising, and we do not build advertising profiles.

3. Health data

Data about your sleep, heart rate, recovery and training can reveal information about your health. The GDPR treats it as a special category and we process it only with your explicit consent, given when you connect your watch account. You can withdraw it at any time by disconnecting your watch or deleting your account; withdrawal does not affect what was done before. If you withdraw, Uknno can no longer work for you, since reading that data is its purpose.

Uknno is not a medical device and does not give medical advice. We do not use your health data to make decisions that have legal or similarly significant effects on you.

4. AI processing

You are talking to an AI, not a person. To answer you, the content of your messages and the watch data needed for your question are sent to our language-model provider (Anthropic), which processes it only to produce the response. We contractually require our providers not to use your content to train their models.

An AI can be wrong. Check anything that matters, and see a health professional for medical questions or before starting an intense programme.

5. Who receives your data

Only providers that help us run Uknno, under data processing agreements:

We update this list when a provider changes. We never sell or rent your data.

6. Transfers outside the EU

Some providers are based in the United States. Transfers rely on the EU-US Data Privacy Framework where the provider is certified, or on the European Commission's Standard Contractual Clauses, with additional safeguards where needed. You can ask us for a copy of the safeguards.

7. How long we keep it

DataRetention
Waitlist emailUntil you unsubscribe, and at most 3 years after our last contact
Account, watch data and conversationsWhile your account is active. Deleted within 30 days of closing it (backups: 30 more days)
Invoices and payment records10 years (French accounting law)
Technical logs12 months
Messages to us3 years after the last exchange

8. Your rights

You can, at any time and free of charge: access your data, correct it, delete it, receive a copy in a portable format, restrict or object to a processing, withdraw a consent, and set instructions for your data after your death (French law). Most of this will be available in the app (export and delete). For anything else, write to hello@uknno.com. We answer within one month.

If you think we are not respecting your rights, you can complain to the CNIL (Commission Nationale de l'Informatique et des Libertés, 3 Place de Fontenoy, TSA 80715, 75334 Paris Cedex 07, cnil.fr) or to the data protection authority of your country.

9. Security

Data is encrypted in transit (HTTPS) and at rest, access is limited to what the service needs, and sign-in to your watch account never exposes your password to us. No system is perfectly secure. If a breach puts your rights at risk, we will tell you and the CNIL within the legal deadlines.

10. Cookies

This website sets no cookies and uses no analytics or advertising trackers, so there is no cookie banner. When you subscribe you are sent to a Stripe page, which sets its own cookies under its own policy. If we add cookies later, we will ask for your consent first when the law requires it, and update this page.

11. Age

Uknno is for adults. You must be at least 18 to create an account.

12. Changes

If we make a significant change, we will tell you by email or in the app before it applies. The date at the top is the last update.
