Privacy policy
Last updated: 3 August 2026
This policy describes exactly the personal data processing carried out by this website. There are two: the contact form and audience measurement. The site offers no user account, no ordering and no payment, so no data is collected for those purposes.
Data controller
PowerChain Systems, SASU with share capital of €1,000, 989 094 891 R.C.S. Versailles,
21 avenue du Général de Gaulle, 78490 Méré, France.
Contact: e.leiber@powerchain-systems.com
No data protection officer has been appointed: the company does not fall within any of the
mandatory cases set out in Article 37 GDPR.
Processing 1 — Contact form
| Data collected | First name, last name, email address, and if you provide them: telephone and company. Subject and content of your message. |
|---|---|
| Purpose | To answer your quote or information request, and to follow up on the resulting commercial exchange. |
| Legal basis | Your consent (Article 6(1)(a) GDPR), collected through the checkbox on the form. You may withdraw it at any time. |
| Mandatory fields | Fields marked with an asterisk are required to process your request. Without them the form cannot be submitted. |
| Retention | 3 years from the last contact, in line with the French data protection authority’s guidance on commercial prospecting. |
| Recipients | Eric Leiber, sole recipient of the messages. Emails transit through and are stored on the mail servers of the hosting provider o2switch SAS (France). No data is sold or disclosed to third parties. |
| Transfers outside the EU | None. |
Processing 2 — Audience measurement
| Tool | Google Analytics 4, with IP anonymisation enabled. |
|---|---|
| Data collected | Pages viewed, date and time, visit duration, referrer, device and browser type, truncated IP address, random measurement identifier. |
| Purpose | To measure site traffic over time and understand which content is read. No individual decision-making, no advertising profiling. |
| Legal basis | Your consent (Article 6(1)(a) GDPR), collected through the banner shown on your first visit. No measurement cookie is set before you accept, and declining is as easy as accepting. |
| Retention | Cookie: 6 months maximum. Audience data retained by Google for 14 months. |
| Recipient | Google Ireland Limited, and Google LLC as a sub-processor. |
| Transfers outside the EU | Yes. Data may be transferred to the United States. The transfer relies on the European Commission adequacy decision of 10 July 2023 on the EU–US Data Privacy Framework, to which Google LLC is certified, supplemented by standard contractual clauses. |
You may change your choice at any time using the “Cookie settings” button in the footer of every page. See also the cookie policy.
Server logs
The hosting provider keeps connection logs (IP address, date, resource requested) for security and diagnostic purposes. This processing relies on the legitimate interest in keeping the service secure, and these logs are not used for commercial purposes.
Your rights
Under Regulation (EU) 2016/679 and the French Data Protection Act, you have the right to:
- Access — confirm whether your data is processed and obtain a copy;
- Rectification — have inaccurate or incomplete data corrected;
- Erasure — request deletion of your data;
- Restriction — request that processing be temporarily suspended;
- Object — object to processing based on legitimate interest;
- Portability — receive your data in a structured, machine-readable format;
- Withdraw consent — at any time, without affecting the lawfulness of processing carried out beforehand.
How to exercise your rights
Write to e.leiber@powerchain-systems.com, or by post to the registered office given in the legal notice. You will receive a reply within one month. Proof of identity may be requested where there is reasonable doubt as to the identity of the requester.
Complaints
If, having contacted us, you consider that your rights are not respected, you may lodge a complaint with the French data protection authority (CNIL): 3 place de Fontenoy, TSA 80715, 75334 Paris Cedex 07, France — www.cnil.fr.

This policy may change if the processing changes. The date of the last update appears at the top of this page.
