This section of our Canllaw i Ddiogelu Data contains guidance on key themes and topics, explaining how the law applies in a specific context. It is for data protection officers and others who have day-to-day responsibility for data protection.

It covers the Data Protection Act 2018 (DPA 2018), and the General Data Protection Regulation (UK GDPR) as it applies in the UK.

We have published guidance on children’s data. We have also published guidance on political campaigning, guidance on direct marketing and guidance on AI. We are currently developing guidance on a number of key themes including national security, and various technologies. This section will expand over time as our work develops.

Each page summarises the key points you need to know, answers frequently asked questions, and contains practical checklists to help you comply.

Where relevant, we also link to detailed guidance and other resources.
