.. for Category 1 services. I've already noted that several age verification services explicitly promise _not_ to retain your identity.

I'm having trouble working out what's category 1. Schedule 1 defines exemptions https://www.legislation.gov.uk/ukpga/2023/50/schedule/1/part... ; otherwise this refers OFCOM to "critera" which I can't find.

As I understand it, Wikipedia are seeking judicial review of OFCOM's placing them in category 1, which requires the most stringent checks including identity.

I made no mention of identity retention.
