Overview

has been required since 12 September 2025. Before a is bought, rented, or leased, Article 3(2) requires the seller, rentor, or lessor to give the prospective user specified information about the . Before a related-service contract is concluded, Article 3(3) places a separate disclosure duty on the related-service provider. The product notice must explain generation, storage, retention, and access. The related-service notice must also identify the prospective , describe intended use and sharing, and explain the complaint and third-party-sharing routes. Neither notice is a declaration of conformity or a substitute for GDPR transparency information.

Question 1

What pre-contract information does the EU Data Act require before buying, renting, or leasing a connected product?

Before conclusion of a purchase, rent, or lease contract for a , Article 3(2) requires the seller, rentor, or lessor to give the user clear and comprehensible information. The disclosure must cover the type, format, and estimated volume of the connected product can generate.

The same pre-contract notice should also tell the user whether the product can generate data continuously and in real time, whether data can be stored on the device or on a remote server, the intended retention duration where applicable, and how the user may access, retrieve, or, where relevant, erase the data.

  • Describe the data in user-facing terms, then add format and estimated volume.
  • State whether generation is continuous or real time when the product has that capability.
  • Explain data storage location, retention duration where applicable, and the technical access, retrieval, or erasure route.
Question 3

Which data categories should the EU Data Act Article 3 notice describe?

The Article 3 notice should focus on and data, not a broad inventory of every file associated with the product. Commission guidance describes Chapter II as covering raw and pre-processed data that are readily available to the , including relevant metadata, while inferred or derived data and protected content can fall outside that Chapter II access scope.

For a useful pre-contract notice, translate internal labels such as telemetry, diagnostics, sensor logs, or app events into the Data Act categories that matter to the user: , data, readily available data, relevant metadata, and material that is not being offered because it is derived, inferred, content, or otherwise outside the access duty.

  • Identify generated by the and data generated during the service.
  • Describe raw and pre-processed data that are readily available, including relevant metadata needed to use them.
  • Do not imply that inferred insights, derived analytics, or protected content are automatically available under Article 3.
Question 4

How should the pre-contract notice explain direct and indirect data access under the EU Data Act?

Article 3(1) requires connected products and related services to be designed so and data are easily, securely, and freely accessible to the user in a structured, commonly used, machine-readable format, and directly accessible where relevant and technically feasible.

The pre-contract information should therefore say whether access is direct, indirect, or split by data type. Commission FAQ material explains direct access as user access without asking the to act, while indirect access means the user has to ask the data holder, for example through a portal or approval process.

  • Name the user interface, API, export, account, portal, or request route used for each major data category.
  • State when direct access is available and when the user must request access from the .
  • Explain the terms of use and quality of service for the technical means of access or retrieval.
Question 5

Does the EU Data Act pre-contract notice have to identify the data holder?

Yes for related services. Article 3(3) requires the provider to disclose the prospective 's identity, including its trading name and geographical address, plus means for quick and efficient communication. For a without a related-service contract, Article 3(2) does not list the data holder's identity among the seller's mandatory disclosures, although the user still needs a workable access route.

Commission FAQ material warns that the manufacturer is not always the . A provider or another entity may be the data holder if it controls access to readily available data, and users must be told who the data holder or data holders are before signing the relevant contracts.

  • Name each prospective in the contract pack or linked pre-contract notice.
  • Provide a trading name, geographical establishment address, and efficient contact channel where Article 3(3) applies.
  • Avoid saying 'manufacturer' when a provider, component supplier, or other contracted party is the actual for a data stream.
Question 6

What should the EU Data Act pre-contract notice say about sharing data with third parties?

For related services, Article 3(3) requires information on how the user can ask for data to be shared with a third party and, where applicable, how to end that sharing. It also requires disclosure of whether the prospective intends to allow one or more third parties to use the data for purposes agreed with the user.

The notice should not overpromise third-party access. Commission guidance states that users can ask data holders to share data with a third party of their choice, but Digital Markets Act gatekeepers are excluded from the third-party role and the Data Act does not oblige a to share with third parties based outside the EU.

  • Explain the user request path for third-party sharing and the stop-sharing path where it applies.
  • State any plan to let third parties use data for purposes agreed with the user.
  • Do not present DMA gatekeepers or non-EU third parties as guaranteed recipients under the Data Act access right.
Question 7

How does GDPR limit EU Data Act pre-contract information and later access to personal data?

The Data Act does not supersede the GDPR. Commission FAQ material states that the GDPR is fully applicable to personal data processing under the Data Act, and that GDPR rules prevail in a conflict. Article 3 disclosures can describe personal-data categories and access routes, but they do not create a new legal basis for collecting, generating, or disclosing personal data.

Where the user requesting data is not the data subject, personal data can be made available only if there is a valid GDPR legal basis. A practical notice should therefore separate personal and non-personal data where possible, explain when anonymised data may be provided, and avoid suggesting that Data Act access overrides privacy, confidentiality of communications, or data subject rights.

  • State which generated data may contain personal data and which access paths involve personal data processing.
  • Do not use Article 3 wording as a substitute for GDPR transparency notices or a GDPR legal basis.
  • Preserve the GDPR boundary when explaining user access, third-party sharing, anonymisation, and mixed personal/non-personal datasets.
Question 8

What trade secret and security information belongs in the EU Data Act pre-contract package?

Article 3(3) requires the related-service notice to say whether a prospective is the holder of trade secrets contained in accessible or generated data, and, if not, to identify the trade secret holder. The Data Act also allows safeguards for trade secrets and security, but those safeguards should be explained as limits on access or sharing, not as a blanket reason to avoid clear Article 3 disclosures.

A useful pre-contract package should identify trade secret-sensitive data categories at a high level, explain any agreed confidentiality measures, and avoid exposing the secret itself. If security requirements laid down in EU or national law could restrict access or sharing, the notice should point users to the practical consequence for the relevant data stream.

  • Disclose whether the prospective is also the trade secret holder where Article 3(3)(h) applies.
  • Identify a separate trade secret holder when the prospective is not that holder.
  • Keep trade secret and security limits specific to the affected data category and access route.
Question 9

Is EU Data Act pre-contractual information the same thing as a declaration of conformity?

No. The Data Act pre-contract obligation is a user-facing information duty about generated data, access, retrieval, identity, third-party sharing, and related limits. It is not a CE-style declaration of conformity or a standalone self-certification document under the Data Act.

A seller, lessor, rentor, or provider may choose a stable web page, product documentation, contract schedule, or another appropriate form for the Article 3 information, as long as the user receives clear and comprehensible information before the relevant contract is concluded.

  • Do not label the Article 3 disclosure as a Data Act conformity declaration.
  • Make the disclosure durable enough for the user to store and consult later.
  • Keep the disclosure consistent across product documentation, website copy, contract schedules, and support answers.
Question 10

What records should teams keep to support the EU Data Act pre-contract information answer later?

Keep the version of the disclosure that the prospective user could see before contracting, together with its publication or deployment date, the product model or related-service version, market and language, sales or rental channel, and contract version. A later reviewer should be able to prove both what the notice said and when it appeared in the user journey.

Behind the notice, retain the data inventory and field-to-disclosure map supporting type, format, estimated volume, generation frequency, storage or retention, direct or indirect access, identity, intended use, third-party sharing, trade-secret holder, contract duration and termination, complaint route, and Article 5 request process. Record assumptions where a volume, retention period, or planned use is not fixed.

  • Archive the exact notice, locale, channel, product or service version, contract version, and pre-contract display evidence.
  • Keep the data inventory, access design, retention rule, intended-use record, complaint route, and approver behind each disclosure.
  • Record changes and effective dates so an older transaction can be matched to the notice shown at that time.
Question 11

Which team should own the Data Act pre-contract disclosure process and keep the templates current?

The actor with the Article 3 duty should own delivery: the seller, rentor, or lessor for the connected-product disclosure and the related-service provider for the service-contract disclosure. Internally, assign one content owner who can stop release when the disclosure is missing and one technical owner who can confirm the data fields, access route, volume, frequency, storage, and retention statements.

Legal should map each statement to Article 3, privacy should keep GDPR transparency separate but consistent, the or prospective data holder should approve intended-use and sharing language, and support should maintain the contact and complaint route. Where different companies fill these roles, the contract should assign who supplies updates and how quickly the sales channel must publish them.

  • Name the seller, rentor, lessor, or related-service provider responsible for giving the applicable disclosure.
  • Assign technical, legal, privacy, data-holder, and support approvers for the facts they control.
  • Define a release gate and supplier-update path so changed data flows reach every sales and contracting channel.
Question 12

What evidence makes the EU Data Act pre-contract information answer usable for a later reviewer?

Test the disclosure against the product and service rather than reviewing text alone. A usable file links every Article 3 statement to a data dictionary field, architecture or API record, retention configuration, contract clause, data-holder contact, intended-use approval, sharing flow, and complaint channel. A sample purchase, rental, lease, or service sign-up should confirm that the correct notice appears before the user commits.

Reassess after a new product model, firmware or app release, changed , new data field, changed format or access method, revised retention, new , new intended use or recipient, contract change, or complaint-channel change. Preserve the old notice for earlier transactions and issue a new effective version instead of overwriting the evidence.

  • Run a channel sample that proves the notice is clear, accessible, and shown before contract conclusion.
  • Trace every material statement to current technical, contractual, privacy, and support evidence.
  • Version and reapprove the disclosure whenever the product, service, data, access, use, sharing, or complaint path changes.
