The law

What the Data Act changes, exactly

This page sets out the mechanism of Regulation (EU) 2023/2854 (the “Data Act”) as it applies to connected products. It is written to be useful even without us: a reader can use it to exercise their rights themselves. It does not constitute legal advice.

The three roles

RoleWhoWhat the Regulation grants or imposes on them
User Whoever owns or leases the product — an establishment, a company, an individual Access the data generated by the use of their product; require its transmission to a third party of their choosing (arts. 4 and 5)
Data holder Most often the manufacturer, which operates the product's cloud Give access to the data without undue delay, of the same quality as available to it, continuously and in real time where technically feasible (arts. 4 and 5)
Recipient third party The provider mandated by the user — our role Receive the data under mandate, process it solely for the purposes agreed with the user (art. 6)

Frequently asked questions

Who is the “data holder”? Is it always the manufacturer?

No. The holder is whoever has the ability to make the data available — most often the manufacturer, because it operates the product's cloud, but it may be a related service provider, a platform operator or an integrator. A single product may have several holders. This is particularly common in building management, where the equipment, the supervision and the hosting are often handled by three different companies. Identifying the right counterpart is the first practical difficulty of a request.

Is my installed fleet covered?

For the access rights (articles 4 and 5): yes, whatever the date the products were placed on the market, since 12 September 2025. For l'design obligation (article 3), which applies from 12 September 2026: no, it covers only products placed on the market from that date. The detail of this distinction, which is the most widespread source of confusion.

How does this differ from the GDPR?

The GDPR protects personal data and gives rights to the data subject. The Data Act organises access to the données générées par l'usage d'un produit connecté, whether personal or not, for the benefit of the user — which may be a company or an establishment. The two texts overlap: where personal data is involved, the GDPR continues to apply in full, and the Data Act does not by itself create a legal basis for processing it.

Can the holder refuse?

It may invoke certain grounds, in particular the protection of trade secrets, under defined conditions, and it may ask for verification of the user's status. A refusal must give reasons. In practice, a reasoned refusal — like the absence of a reply within a reasonable time — is documented: it is the material for any later complaint.

Can the holder charge for making the data available?

Not to the user for access to their own data: that is free of charge. However, where the data is transmitted to a third party designated by the user, the holder may ask that third party for reasonable and non-discriminatory compensation (article 9). That is a business-to-business relationship, distinct from the right of access itself.

What if the holder does not reply?

Keep proof of the request and of its date, follow up, then record the silence at the deadline. The Regulation provides for complaint mechanisms before the competent authority and for dispute settlement. Designating the competent authorities is a matter for each Member State; for the personal-data aspect, the CNIL remains the counterpart in France. A dated, complete file is, in every case, the indispensable prerequisite.

Can I entrust the exercise of these rights to a provider?

Yes: article 5 expressly provides for transmission to a third party designated by the user. That third party may process the data only for the purposes agreed with the user, may not use it to develop a product competing with the original connected product, and must erase it once it is no longer necessary for the agreed purpose. That is our role.
