Overview

Article 3 of the EU Data Act turns data access into a product design requirement for connected products and related services. This FAQ explains what must be designed into user access paths, when indirect access under Article 4 is still needed, and what evidence should prove that access is easy, secure, free of charge, and usable.

Question 1

What does direct access by design actually mean under the EU Data Act Article 3 obligation?

The Data Act context is the starting point for this answer. Direct access by design means the connected product and any related service must be built so the user can access product data and related-service data by default. Article 3 requires the access path to include relevant metadata, use a comprehensive, structured, commonly used and machine-readable format, and be easy, secure, and free of charge.

The obligation is not just a helpdesk process. Product teams should decide during architecture, release, and UX design whether the user will retrieve data from on-device storage, an app, an account portal, an API, or a remote server. Where direct access is relevant and technically feasible, it should be available without making the user ask support to manually extract the data.

  • Treat direct access as a product requirement for each connected product and related service, not as a later compliance add-on.
  • Specify the user-facing route, authentication method, data format, metadata, retention assumptions, and support fallback.
  • Test whether a real user can retrieve and understand the data without non-neutral interface patterns or unnecessary identity checks.

Question 2

Which categories of data must the access design cover under the EU Data Act Article 3 rules?

The Data Act context is the starting point for this answer. The design should cover product data and related-service data that are readily available to the data holder. The Commission explains this as raw and pre-processed data generated from use of a connected product or related service that can be accessed without disproportionate effort, including relevant metadata.

The data map should distinguish raw data, pre-processed data, relevant metadata, personal data, non-personal data, inferred or derived data, trade-secret material, and data that is not stored or transmitted by the product design. Inferred or derived insights produced through additional investment, such as proprietary analytics, should not be mixed into the direct-access dataset unless the parties have agreed otherwise.

  • Inventory generated data by field or stream, including sensor data, event data, timestamps, basic context, units, format, collection frequency, and estimated volume.
  • Flag data that is available on-device, sent to a remote server, generated by a related service, or unavailable because the product does not store or transmit it.
  • Record why each exclusion is outside the Article 3 or Article 4 access path, especially for derived insights, trade-secret material, and personal data limits.

Operationalise Data Act direct access by design

Turn Article 3 into product release gates, data maps, metadata dictionaries, user access paths, safeguard records, and evidence that product, legal, security, and support teams can maintain.

Question 3

When is indirect access under Article 4 still needed under the Data Act?

The Data Act context is the starting point for this answer. Article 4 applies where the user cannot directly access the data from the connected product or related service. In that case, the data holder must make readily available data and necessary metadata accessible to the user without undue delay, with the same quality available to the data holder, and through a simple electronic request where technically feasible.

A product can therefore need both paths: direct access for data that can be exposed by design, and a request-based route for data that cannot be directly accessed. The request route should not be used to compensate for avoidable design gaps in a new product that falls under Article 3.

  • Document why each dataset is direct-accessible, request-accessible, or outside the readily available data boundary.
  • Make the indirect request channel simple, electronic where technically feasible, and connected to the same data inventory used for product design.
  • Keep evidence that indirect access does not degrade quality, format, metadata, security, or user comprehension compared with what the data holder has.

Question 4

Does direct user access remove the need to support third-party sharing under the Data Act?

The Data Act context is the starting point for this answer. No. The Commission FAQ states that users can still ask a data holder to transfer data to a third party under Article 5 even where the user already has direct access under Article 3. Direct access helps the user retrieve data, but it does not supersede the separate user right to have a data holder make readily available data available to a chosen third party.

The product design should therefore avoid a dead end where the user can download data but cannot authorize third-party sharing. Teams should provide a clear route for third-party requests, eligibility checks, trade-secret safeguards, and refusal or suspension records where the Data Act allows them.

  • Add a third-party sharing path alongside direct user export where a data holder has readily available data.
  • Exclude Digital Markets Act gatekeepers from the Article 5 third-party route where the Data Act does so.
  • Keep user authorization, third-party identity checks, purpose, scope, format, metadata, delivery, and safeguard records together.

Question 6

How should security and identity controls be designed under the Data Act?

The Data Act context is the starting point for this answer. Security controls can verify that the requester is a user and protect the data infrastructure, but they should not make access unduly difficult. Article 4 limits verification requests to necessary information, and the Commission FAQ points to simple request mechanisms and automatic execution where possible.

Security also has a substantive limit: users and data holders may restrict access, use, or onward sharing if processing could undermine security requirements of the connected product laid down by EU or national law, with serious adverse effects on people's health, safety, or security. That is narrower than a general preference not to share data.

  • Use proportionate authentication, account, device-pairing, or proof-of-use controls that fit the product and expected user base.
  • Avoid dark patterns, non-neutral choices, excessive identity documents, unnecessary logs, or manual clearance where automatic access is feasible.
  • If security requirements justify a restriction, record the legal requirement, risk analysis, affected data, user notice, authority notification, and challenge route.

Question 7

How should trade secrets be handled without blocking lawful access under the Data Act?

The Data Act preserves trade secrets, but it does not allow a blanket trade-secret label to erase user access. The data holder or trade-secret holder must identify protected data, including in relevant metadata, and agree proportionate technical and organisational measures such as confidentiality terms, strict access protocols, technical standards, and codes of conduct.

Withholding, suspension, or refusal should be exceptional and documented. Article 4 requires written substantiation and competent-authority notification when data sharing is withheld, suspended, or refused on trade-secret grounds. Refusal for serious economic damage must be assessed case by case and supported by objective elements.

  • Mark trade-secret fields in the data inventory and metadata instead of hiding the entire dataset.
  • Choose proportionate measures that preserve confidentiality while leaving the usable data access path open where possible.
  • Keep written reasons, objective evidence, user notices, competent-authority notifications, and challenge-route records for any withholding, suspension, or refusal.

Question 8

When does the Article 3 design obligation apply under the Data Act?

The Data Act generally applies from 12 September 2025, but Article 50 states that the obligation resulting from Article 3(1) applies to connected products and related services placed on the market after 12 September 2026. Teams should keep those two dates separate in release plans and customer-facing materials.

For products already in the market, other Data Act duties can still matter, including user access under Article 4, data holder contracts for non-personal readily available data, and third-party sharing under Article 5 where the conditions are met. Do not present the later Article 3 design date as a full exemption from the Data Act.

  • Tie the Article 3 release gate to products and related services placed on the market after 12 September 2026.
  • Review older products separately for request-based access, data-use contracts, third-party sharing, and support processes.
  • Keep the date source in the design record so sales, legal, product, and support teams do not reuse the wrong Data Act date.
Citations
Question 9

What evidence should prove that the access design is compliant under the Data Act?

The evidence file should let a reviewer connect the product architecture to the Data Act duty without reconstructing decisions from tickets. Keep a data inventory, Article 3 design specification, pre-contract disclosure, UX/API evidence, security and identity assessment, trade-secret register, request-path procedure, and release approval.

Evidence should also show that the access path works in practice. Useful records include sample exports, API schemas, metadata dictionaries, user journey screenshots, access logs limited to what is necessary, support scripts, test results for machine readability, and records of any security or trade-secret restriction.

  • Preserve a direct-access matrix showing each dataset, access route, format, metadata, retention assumption, safeguard, and owner.
  • Retain test evidence that the user can access data easily, securely, free of charge, and in the promised format.
  • Log exceptions with the affected data, legal basis, reason, user notice, authority notice where required, and remediation or review date.

Question 11

Does the EU Data Act require direct access to be free of charge for the connected-product user?

Under the Data Act, Article 3 requires direct access to product and related-service data to be provided to the user easily, securely, and free of charge, in a comprehensive, structured, commonly used, machine-readable format with relevant metadata. A data holder cannot put the statutory user access behind a fee or a premium tier.

Compensation can arise in the separate context of sharing with a third party under Articles 4 and 5, but that is distinct from the user's own free access by design, which the product must support without charge.

  • Provide the user's own direct access free of charge in a structured, machine-readable format.
  • Keep any third-party sharing compensation separate from the user's free statutory access.
Question 12

When must a connected product be redesigned to meet the EU Data Act direct-access obligation?

Under the Data Act, the Article 3 design obligation applies to connected products and related services placed on the market after 12 September 2026, so products designed before that date are not retrofitted by the rule but may still owe Article 4 access on request. Teams should map each product to the date it was or will be placed on the market.

A product roadmap crossing that date should bake direct access into the design rather than relying on a manual export, so the access path is easy, secure, and free of charge from launch.

  • Apply the Article 3 design obligation to products placed on the market after 12 September 2026.
  • Design direct access into new products rather than relying on a manual support export.
