Privacy policy
Last updated: September 2026.
Purpose of this policy
This policy explains how Tech 4 Team SAS, operating under the Arenametrix brand, processes the personal data of visitors to the arenametrix.com website, of people who contact us and of users of the Arenametrix platform.
It supplements the legal notice and the terms and conditions. Processing carried out on behalf of our clients within the platform is covered by a separate data processing agreement appended to the contract.
Who is responsible for your data
For the website and the business relationship
Tech 4 Team SAS, a simplified joint-stock company with a share capital of EUR 27,493, registered in Paris under number 794 062 497, 157 boulevard Macdonald, Le Cargo, 75019 Paris, France, acts as data controller.
For the data hosted in the platform
When a client organisation uses Arenametrix to manage its own audiences, it decides on the purposes and means of the processing: it is the data controller, and Tech 4 Team SAS acts as a processor within the limits set by the contract. Requests about this data should be sent to the organisation concerned, which remains your point of contact.

- Google Ireland Limited: tag management and website audience measurement
- Infrastructure and tooling providers needed to run the platform, listed in the data processing agreement provided to clients
Each provider is bound by a contract that complies with Article 28 of the GDPR. No data is sold or passed on to third parties for advertising purposes.
Transfers outside the European Union
Some providers are based in the United States or host part of the processing there. These transfers are covered by the safeguards provided for in Chapter V of the GDPR: the European Commission standard contractual clauses and, where applicable, certification under the EU-US Data Privacy Framework.
You can obtain a copy of the applicable safeguards by writing to the address given in the Contact section.
Security
We implement technical and organisational measures appropriate to the risk: HTTPS encryption, access rights management, authentication, logging, backups, staff awareness and contractual safeguards with our providers.
In the event of a data breach likely to result in a high risk to your rights, you will be informed in accordance with Article 34 of the GDPR.
Cookies and trackers
On your first visit, a banner lets you accept or refuse the trackers that are not strictly necessary. Your choices are saved and can be changed at any time from the same banner.
Necessary trackers
Website operation, security, load balancing and remembering your consent choices. They do not require your consent.
Audience measurement
Visit and usage statistics, used to improve the website content.
Marketing trackers
Measuring the effectiveness of our campaigns and personalising the content offered to you. They are only set with your explicit consent.
You can also set your browser to block all or some cookies. Refusing necessary trackers may prevent access to some features.
Your rights
You have the right to access, rectify and erase your data, to restrict or object to its processing, to data portability, and to give instructions about what happens to your data after your death. You can also withdraw your consent at any time.
To exercise these rights, write to the address given in the Contact section, stating the purpose of your request. Proof of identity may be requested if there is reasonable doubt about your identity. You will receive an answer within one month, which may be extended by two months for complex requests.
If the data concerned is processed on behalf of a client organisation, your request will be passed on to it, or you will be asked to send it to that organisation directly.
