How it works in a data room
If an employee or customer of a target makes a request, the controller must look for their data wherever it is held, which can include files uploaded to a deal room. Full-text search across the room, plus the audit trail showing who viewed or downloaded those files, helps locate the material. The data room provider, acting as processor, supports the controller but does not answer requests directly. Under the GDPR the response is generally due within one month, extendable in some cases.
Why it matters in a deal
Employees who learn that their company is being sold sometimes use access requests to find out what was shared about them. A request can expose over-sharing, such as full HR files uploaded without need, so sellers benefit from limiting personal data in the first place. Rooms with clear structure and search make responses faster and cheaper. Similar rights exist under California law and other regimes.
Example
Three months into a sale process, a senior manager at the target asks for all personal data the company holds about her. The privacy team searches the data room, finds her contract and appraisal in the HR folder and the logs showing two bidder advisers viewed them. They include this in the response and review whether the appraisal needed to be shared at all. The Germany guide covers local privacy expectations.
