The General Data Protection Regulation (GDPR) is the biggest change to affect Data Protection for years. Every organisation is going to be affected and your church is not excluded from these changes. This new Regulation from the European Union comes into effect on the 25th May 2018 and organisations need to be compliant with this Regulation by that date.
GDPR gives a lot more rights to individuals on how their personal data is stored and processed and your church must have a lawful basis for holding personal data.
