GDPR is important, however clubs shouldn’t be daunted.
All players, parents and members personal data should be stored on the RFU Game Management System (GMS).
The RFU has a very useful resource page for clubs. https://www.englandrugby.com/run/club-management/policies-and-procedures/data-protection
The CB Data Officer is also on hand to advise where able and can be contacted via email dataofficer@leicestershirerugbyunion.co.uk
