Last updated: May 3, 2025 This privacy policy describes how Leonhard Euler R&D 4 Ukizz, operator of the Ukizz application and website, collects, uses, stores, and protects users' personal data. Ukizz is a tool for personal clarification and thought organization. It is not a medical, psychological, psychiatric, or emergency service.
1. Data Controller
The data controller is:
- Company: Leonhard Euler R&D 4 Ukizz
- Contact email: contact@ukizz.com
- SIREN/SIRET: FR-405305517
- Legal representative: Leonhard Euler R&D 4 Ukizz
2. Data Collected
When using Ukizz, we may collect the following categories of data:
- Identification data: email address, user ID;
- Account data: encrypted password, preferences, language, time zone;
- Subscription and payment data: subscription status, Stripe customer ID, payment history;
- Bank details: these are processed by our payment provider; Ukizz never has access to them.
- Usage data: login dates, sessions, pages viewed, clicks, application events;
- Technical data: security logs;
- Conversational data: messages entered by the user, generated responses, summaries, objectives, protocols, progress steps;
- AI usage data: number of incoming and outgoing tokens, model used, estimated cost, response time;
- Consent data and preferences related to cookies or communications.
Users are advised not to enter data strictly necessary for medical care, information concerning third parties without their consent, or data they do not wish to have processed within the scope of the service.
3. Purposes of Processing
Data is processed for the following purposes:
- creation and management of the user account;
- provision of the Ukizz service;
- processing of conversations and generation of responses using artificial intelligence;
- progress tracking, summaries, and user history;
- management of subscriptions, payments, invoices, and access;
- user support;
- security, abuse prevention, and incident detection;
- audience measurement, usage statistics, and service improvement;
- technical monitoring of costs, tokens, performance, and AI models;
- compliance with legal and regulatory obligations.
4. Legal Basis
Depending on the circumstances, processing is based on:
- the performance of the contract when processing is necessary for the provision of the service;
- consent when required, particularly for certain cookies or communications;
- legitimate interest in securing, improving, and administering the service;
- Compliance with legal obligations, including accounting, tax, and regulatory requirements.
5. Sensitive Data
Conversations with Ukizz may contain intimate or personal information. Ukizz is not intended to collect medical data in the strict sense, to make a diagnosis, or to provide therapeutic monitoring. If the user voluntarily enters sensitive information, it will be processed only within the scope of the requested service, according to the safeguards described in this policy. In case of severe distress, immediate danger, or a suicidal crisis, the user must contact emergency services or a qualified professional. In ANY situation where you feel unwell or uncomfortable with a situation or response, talk about it: to a relative, a friend, or a healthcare professional. Never remain alone in the face of distress. Everyone has the right to have moments when "things are really bad." Talk, talk, talk. It could save your life. Death is also a poor solution: you've treated the symptom instead of the cause, and those around you will be unhappy for the rest of their lives. We have all, to varying degrees, lost a loved one. A friend who died too soon from illness, a relative who committed suicide, an elderly parent who passed away. These moments, for those left behind, are terribly painful because death has this finality that makes every moment of life precious. Don't do this to those around you. Never try to rely on death as a solution: talk. There is bound to be someone who is willing to listen and help you.
6. Data Recipients
Data may be accessible, depending on their respective needs, to the following categories of recipients:
- Authorized personnel of Leonhard Euler R&D 4 Ukizz;
- Hosting providers;
- Payment providers, including Stripe;
- Artificial intelligence service providers used to generate responses;
- Technical, security, email, analytics, or support providers;
- Administrative or judicial authorities when required by law.
We NEVER sell, show, lend, or rent users' personal data to third parties.
7. Artificial Intelligence Providers
To provide the service, Ukizz may transmit certain messages or contextual elements to artificial intelligence model providers. It is anticipated that, in the future, due to reasonable success, Leonhard Euler R&D 4 Ukizz will use its own AI on its own servers. The choice of provider may change for reasons of quality, cost, availability, or security.
8. Transfers outside the European Union
Some service providers may process data outside the European Union. In this case, we ensure that appropriate safeguards are in place, such as standard contractual clauses or any other mechanism recognized by applicable regulations.
9. Data Retention Period
Data is retained for periods proportionate to the purposes for which it is processed:
- User account: for the duration of the account's existence unless the user requests the deletion of certain conversations (a function is provided for this purpose);
