The Institute of Fundraising has updated its free guide to the General Data Protection Regulation for fundraisers.
The umbrella body said the latest version of the guide, first published in 2017, included new information on minimising data protection risks and tips on how fundraisers could assess whether they had a legitimate interest for carrying out direct marketing under the GDPR.
The regulation, which came into force on 25 May last year, introduced stricter measures on how organisations could use personal data.
Sam Boyle, policy and information officer at the IoF, said he hoped the guide would provide a good starting point for charities to get things right on GDPR.
"As the data protection landscape changes, parts of this guidance might need refreshing, but the core tenets of the advice we give should remain relevant for a long time to come," he said.
"With new developments such as e-privacy on the horizon, there may well be a need to refresh the guidance when appropriate."
