As part of its commitment to ensure regulatory coherence between the UK data protection regime and the new online safety regime, the ICO has published draft new guidance(1) on the use of profiling tools for online safety. This guidance aims at reminding organisations offering user-to-user services who wish to use profiling to meet their Online Safety Act 2023 (OSA) commitments of the relevant UK GDPR rules. The guidance applies to all organisations carrying out profiling, as defined in the GDPR (as well as organisations providing profiling products and services). The ICO is seeking feedback on this guidance, with the response period to close on 31 October 2025.
