Information notices
One of the drivers behind the EDA is increasing transparency. Data holders need to be clear about the data they collect and ensure that users are aware of how they too can access that data. This information needs to be provided pre-contract in a "clear and comprehensible manner".
Data holders—be they sellers, manufacturers, renters, or lessors—must inform users about the type, format, and estimated volume of data the product can generate, including whether data is created continuously or in real-time, how data is stored, retention periods, and ways to access, retrieve, or erase their data. Related digital services come with even more disclosure duties: in addition, users must be told about the frequency of data collection, how the data holder plans to use the data and with whom the data holder plans to share it (including contact details), how contracts can be ended, the user's right to complain, and information about trade secrets.
The Data Act suggests that one way to satisfy the information obligation is to maintain a stable uniform resource locator (a URL) distributed as a web link or QR code to point to the relevant information prior to concluding the contract.
Model contract terms (MCTs)
Data holders can only use data on the basis of a contractual agreement with the user – so data holders must ensure that their user-facing terms and conditions are sufficiently clear about the purposes for which they will use data and with whom they are entitled to share data. These limitations apply in addition to the constraints already imposed on business' use of personal data under the GDPR.
Contracts with consumers will be subject to consumer protection laws but the EDA will also require all B2B data sharing contracts to be on terms that are fair, reasonable and non-discriminatory (FRAND) and will impose a reverse burden of proof on data holders to prove that their terms and conditions are non-discriminatory. This obligation will apply to new contracts concluded after 12 September 2025. However, from 12 September 2027, it will also apply to certain pre-existing contracts.
An expert group appointed by the EU Commission has published final drafts of non-binding model contractual clauses (MCTs) under the EDA to cover data access and use, including terms on reasonable compensation and the protection of trade secrets – the EU Commission must decide whether it wishes to adopt them prior to 12 September 2025.
