Overview

Article 3 of Regulation (EU) 2023/2854 is a transparency rule for connected products and related services. It does not create a CE-style conformity declaration; it requires clear user-facing information about generated data, access, storage, retention, data holder identity, third-party sharing, complaints, trade secrets, and contract duration before the relevant contract is concluded.

Section 1

When Data Act Article 3 pre-contractual information must be given to the user

For a connected product, the seller, renter, or lessor must give the Article 3 product-data information before the purchase, rent, or lease contract is concluded.

For a related service, the provider must give the related-service information before the service contract is concluded. The disclosure should be visible where the user is deciding, such as the product page, quote pack, order flow, contract schedule, technical documentation, manufacturer or service-provider website, or another durable form the user can keep.

  • Use one disclosure set for the connected product and a separate disclosure set for each related service that obtains or generates data.
  • Do not substitute a privacy notice, marketing brochure, warranty statement, or product compliance declaration for the Article 3 data-access information.
  • Keep the disclosure stable enough that the user can store it and reproduce it unchanged for later reference.
Section 2

Connected product disclosure items the Data Act requires before purchase

The connected-product disclosure should describe the product data the device is capable of generating. A useful version names concrete categories such as sensor readings, operating status, location or movement data, fault codes, environmental readings, user-interface events, battery status, or other product-specific telemetry when those categories apply.

Article 3 also requires information about whether the product can generate data continuously and in real time, whether it stores data on the device or on a remote server, the intended retention period where applicable, and how the user may access, retrieve, or erase the data.

  • List the type, format, and estimated volume of product data.
  • State whether continuous or real-time generation is possible.
  • State whether storage is on-device, remote, or both, and give the intended retention duration where applicable.
  • Describe the access, retrieval, and erasure route, including technical means, terms of use, and quality of service.
  • Name the format users can expect, such as API response, dashboard export, CSV, JSON, or another structured machine-readable format when available.
Section 4

Data holder identity, data use, and third-party sharing under the Data Act

The related-service disclosure must identify the prospective data holder by trading name and geographical address, and identify other data processing parties where applicable. It must also give fast and efficient communication means for contacting the prospective data holder.

The user also needs to know whether the prospective data holder expects to use readily available data itself, for which purposes, whether one or more third parties may use the data for purposes agreed with the user, and how the user can request sharing with a third party or end sharing where applicable.

  • Name the prospective data holder and contact route in the disclosure, not only in legal entity boilerplate elsewhere.
  • State the provider's own intended uses of readily available data in concrete terms, such as maintenance, service operation, diagnostics, product improvement, or another supported purpose.
  • Explain the user request path for sharing data with a third party and for ending that sharing.
  • Flag restrictions that follow from the Data Act itself, including that gatekeepers under the Digital Markets Act are excluded as eligible third parties under Article 5.
  • Where multiple parties provide an integrated product and service, identify which party the user contacts for which dataset.
Section 5

Data categories and boundaries in Data Act disclosures to avoid overclaiming

Article 3 disclosures should be specific enough for the user to understand what they can later access, but they should not promise access to data that is outside the Data Act access regime.

The Commission explainer states that Chapter II covers raw and pre-processed data generated from use of a connected product or related service that is readily available to the data holder, including relevant metadata. Inferred or derived data and protected content are described as out of scope unless another agreement or rule applies.

  • Separate raw and pre-processed data from inferred, derived, enriched, or proprietary analytics outputs.
  • Include metadata needed to interpret and use the data, such as timestamp, unit, source sensor, product identifier, or basic context where applicable.
  • Do not imply that the Data Act creates a new right for the data holder to use non-personal product data; Article 4 links that use to a contract with the user.
  • Where mixed personal and non-personal data is involved, state that personal data handling still depends on applicable data protection law.
  • Where trade secrets are involved, state the existence of trade-secret data and the identity of the trade secret holder where Article 3 requires it.
Section 6

Complaint, trade secret, and contract details the Data Act disclosure must list

The related-service disclosure must tell the user about the right to lodge a complaint alleging an infringement of Chapter II with the competent authority designated under Article 37.

It must also state whether the prospective data holder is the holder of trade secrets in the accessible or generated data. If the prospective data holder is not the trade secret holder, the disclosure must identify the trade secret holder. The same disclosure set must include the duration of the user-data-holder contract and termination arrangements.

  • Include a complaint notice that points to the competent-authority route rather than a generic customer-support promise.
  • Identify trade-secret status and the trade secret holder before the user contracts for the related service.
  • Explain the contract duration and termination route between the user and prospective data holder.
  • Align the complaint, trade-secret, and termination wording across the service terms, data-access terms, and customer help pages.
Section 7

Evidence to keep that Data Act Article 3 disclosures were actually provided

The evidence record should prove what the user saw before contracting and why the data facts were accurate at that time. It should connect customer-facing wording to the product architecture, service logs, API behavior, retention settings, and contracts.

This evidence is useful for internal release control, sales and ecommerce QA, user disputes, competent-authority questions, and later updates when product data, related-service data, access methods, or retention arrangements change.

  • Keep the exact disclosure version shown for each product, service, SKU, territory, and transaction channel.
  • Keep data-category inventories showing type, format, estimated volume, collection frequency, storage location, retention, and access or erasure route.
  • Keep technical proof for access routes, such as API documentation, export screenshots, data schema examples, quality-of-service terms, and account-request flow evidence.
  • Keep identity and role evidence for the data holder, data processing parties, trade secret holder, and third-party sharing path.
  • Keep release notes or change records showing when new data fields, firmware changes, service updates, retention changes, or third-party sharing changes required disclosure review.
Recommended next step

Data Act Review your Article 3 disclosure pack

Check whether product pages, order flows, related-service terms, data-access documentation, and evidence records all describe the same generated data, access route, retention, data holder, third-party sharing path, and complaint route.
