Recital 73

Data made available to public sector bodies, the Commission, the European Central Bank or Union bodies on the basis of an exceptional need should be used only for the purposes for which they were requested, unless the data holder that made the data available has expressly agreed for the data to be used for other purposes. The data should be erased once it is no longer necessary for the purposes stated in the request, unless agreed otherwise, and the data holder should be informed thereof. This Regulation builds on the existing access regimes in the Union and the Member States and does not change the national law on public access to documents in the context of transparency obligations. Data should be erased once it is no longer needed to comply with such transparency obligations.
