"The States of Guernsey has a dedicated data protection team responsible for the operational implementation of the data protection law in all areas of government activity," explained a spokesperson for the Office of the Data Protection Authority.

"Whilst the ODPA has not been involved in the implementation of this aspect of Phase Four, we are always keen to support the whole regulated community with their compliance duties.

"As part of the Bailiwick community the ODPA welcomes the very positive news that we have been able to move to the next phase so swiftly. The ODPA also recognises that a key element of the next phase is going to be efficient, effective and timely contact tracing."

Businesses with a 'controlled' environment have been collecting personal information since Saturday, when many more were allowed to reopen.

"As with all processing of personal data, it is important that individuals are given information and details about that processing, including what personal data is being collected, how it will be used and who else will have access to it.

"The principles contained within the data protection legislation are there simply to ensure that these elements are included in all processing activities, regardless of their context.

"The reasons for data collection in this context are self evident and ensuring all personal data is handled in a compliant manner will ensure that individuals have trust and confidence in the process as well as in the people directing that process."
