Are there special requirements that apply to the collection or processing of personal data from minors?

Last review date: 13 January 2025

Yes.

A minor within the meaning of data privacy laws is a person below the age of: 18 (but see below).

In what circumstances do these special requirements apply?

Last review date: 13 January 2025

☒         in the context of information society services only if processing is based on consent
☒         other

For the purposes of the general application of the GDPR in Ireland, a reference to "child" in the GDPR is to a person under 18 years of age (section 29, DPA 2018).

However, in the context of information society services, where processing is based on the consent of a child, a child is a person under 16 years of age (section 31, DPA 2018). In this case, consent must be given/authorized by a parent/guardian.

What are the special requirements that apply to collecting or processing personal data from minors?

Last review date: 14 January 2025

☒        consent must be given or authorized by the holder of parental responsibility over the child
☒        additional data subject rights are granted to minors (e.g., deletion, access, transparency)

Additional Rights:

Organizations have an express obligation under the GDPR to ensure that any transparency information about data processing which is addressed to a child under 18 years of age should be in clear and plain language so that the child can understand it (Article 12.1, GDPR and section 29, DPA 2018).

Section 33 of the DPA 2018 provides a specific right to erasure for children where personal data have been collected in relation to the offer of information society services. However this right will not apply where the processing is necessary for the purposes set out in Article 17(3) of the GDPR (e.g., to comply with a legal obligation).

☒        other

The processing of the personal data of a child under 18 years of age for the purposes of direct marketing, profiling or micro-targeting is prohibited (section 30, DPA 2018). No date has been set for the commencement of this provision due to concerns that it imposes limitations in Irish law on the processing of personal data that is lawful under the GDPR.

The DPC has an obligation under section 32 of the DPA 2018 to encourage the drawing up of codes of conduct to contribute to the proper application of the GDPR with regard to:

  • the protection of children;
  • the information to be provided by a controller to children;
  • the manner in which the consent of holders of parental responsibility over a child is to be obtained for the purposes of Article 8 GDPR;
  • integrating the necessary safeguards into processing in order to protect the rights of children in an age-appropriate manner for the purposes of data protection by design and by default; and
  • the processing of the personal data of children for direct marketing purposes and creating personality and user profiles.
