2. What data is collected and for what purposes?
WERIN ensures that it collects only the data strictly necessary for the purpose for which it is processed. Depending on your profile (Visitor or User) and the services you use, the data collected may differ.
2.1 — Data collected from Visitors and Users
Upon access to the platform, WERIN automatically collects certain browsing data:
- IP address, date and time of connection, pages viewed;

You may opt out of marketing communications at any time by clicking on the unsubscribe link in each email.
2.5 — Content you publish on the platform
Comments, reviews and testimonials that you voluntarily publish on the platform constitute personal data of which you remain the owner. By publishing them, you authorise WERIN to use them for promotional purposes, free of charge, for the duration of your registration and for three (3) years after the end of services, under the conditions provided in the ToS.
3. Who receives your data?
WERIN handles your data with the utmost care and shares it only with third parties strictly necessary for providing its services:
- Technical and hosting providers: data hosting, cloud infrastructure, development tools. These providers are contractually bound by confidentiality and security obligations.
- Payment provider: secure processing of your transactions. This provider is responsible for your banking data under its own privacy policy.
- Financial data providers: feeding the platform with market data and company fundamentals.
- Audience measurement tools: WERIN uses Google Analytics 4 (operated by Google Ireland Limited) and PostHog for statistical analysis of platform use. These tools are activated only with your prior and explicit consent, collected via Axeptio, our consent management platform (CMP). Without consent, no browsing data is transmitted to these third parties.
- Public and judicial authorities: upon a request based on legal grounds or in the context of judicial proceedings.
WERIN does not sell or rent your personal data to third parties for commercial purposes.
4. How is your data secured?
WERIN implements appropriate technical and organisational measures to protect your data against any unauthorised access, disclosure or alteration. These measures include in particular:
- Encryption of data in transit (HTTPS/TLS) and at rest;
- Hashing of your password (not readable by WERIN);
- Management of internal access rights according to the least-privilege principle;
- Regular security audits.
In the event of a data breach likely to result in a risk to your rights and freedoms, you will be informed as soon as possible, in accordance with applicable regulations.
5. How long is your data retained?
Your data is retained for the period strictly necessary for the purposes for which it was collected, then deleted or anonymised. As an indication:

6. Data transfers outside the European Union
Where data is transferred to countries outside the European Economic Area, WERIN will ensure that such transfers are framed by appropriate safeguards (adequacy decision of the European Commission or standard contractual clauses), in order to provide a level of protection equivalent to that guaranteed within the European Union.
For any information on these safeguards, you may contact WERIN at admin@werinfinance.com.
7. What are your rights and how to exercise them?
In accordance with applicable personal data protection regulations (GDPR and French Data Protection Act), you have the following rights:

- Right to rectification: have inaccurate or incomplete data corrected.
- Right to erasure: request the deletion of your data under the conditions provided by the regulations.

8. Algorithmic processing and decision support
The WERIN platform relies on an algorithm that generates equity portfolio configurations based exclusively on the criteria entered by the User. This involves automated processing of personal data, the nature of which WERIN wishes to clarify. WERIN is fundamentally conceived as a tool that helps structure the investor's thinking: it does not decide for them; it provides a framework to formalise, organise and visualise their own choices.
Personalised processing, without autonomous decision-making effect
The WERIN algorithm analyses the preferences and criteria expressed by the User to produce a result tailored to their parameters. In this respect, it amounts to a form of profiling within the meaning of the GDPR. However, this processing does not constitute an automated decision producing significant effects on the User, for the following reasons:
- All criteria fed into the algorithm are provided exclusively by the User. WERIN does not infer, complete or modify any parameter without the User's express agreement.
- The result produced is an indicative configuration. It is neither a personalised recommendation nor investment advice, and produces no legal effect or automatic consequence for the User.
- The User remains at all times the sole decision-maker: it is for them to decide freely whether to act on the proposed portfolio, and to execute any orders with the broker of their choice, without WERIN's intervention.
- WERIN executes no orders, holds no assets and acts in no way on behalf of the User.
Legal basis and transparency
This processing is based on the performance of the contract between the User and WERIN: it is the very condition of the service. It is carried out strictly within the limits of the data provided by the User and gives rise to no commercial profiling, advertising targeting or transfer to third parties.
For any question on the operation of the algorithm applied to your data, you may contact our Data Protection Officer at admin@werinfinance.com.
9. Use of cookies
When accessing the platform or using the services, cookies may be placed on your device. The operating conditions and use of these cookies are described in our Cookie Policy, accessible in the footer of the site.
10. Changes to this Policy
WERIN reserves the right to modify this Policy at any time, in particular to comply with regulatory or service changes. Any material change will be notified to Users by email and published on the platform with thirty (30) days' notice. The version in force is the one available on the platform on the date of consultation.
