Tech giant Apple is facing a collective legal action in the United Kingdom valued at £2 billion, brought on behalf of thousands of UK app developers. The lawsuit targets Apple’s App Tracking Transparency framework, alleging that the policy unfairly harmed ad-reliant developers while benefiting Apple’s own expanding advertising business.

The class-action claim was filed by ATT Collective Action Limited and is led by Ann Pope, the former Senior Director for Antitrust at the UK’s Competition and Markets Authority. The filing contends that when Apple introduced the privacy feature in 2021, it imposed far stricter consent requirements on third-party applications than on its proprietary services. According to the claimants, Apple enacted these restrictions without consulting the developer community, severely undercutting revenue for independent businesses. Over the same period, Apple’s internal advertising revenues grew significantly, rising from $1.5 billion in 2020 to approximately $7.4 billion by 2025.
Ann Pope emphasized that while consumer privacy remains essential, digital platforms must not play by different rules than the developers operating within their ecosystems. Under the structure of the filing, UK app developers that generate advertising revenue or spend capital on user acquisition inside third-party iOS apps are automatically included in the legal action unless they explicitly choose to opt out.

This UK lawsuit builds on wider European scrutiny regarding the feature. Regulators in France and Italy have already imposed combined penalties totaling $284 million (£211 million) over Apple’s tracking policies. Furthermore, Apple recently agreed to alter how tracking prompts are displayed following a settlement in Germany, adjustments expected to roll out across the European Union.
Domestically, the Competition and Markets Authority continues its separate investigation into the policy, having previously designated Apple’s mobile platform as holding Strategic Market Status. The legal team handling the current suit, Hausfeld, previously secured a £1.5 billion judgment against Apple at the Competition Appeal Tribunal in 2025. This latest litigation marks another major legal challenge to Apple’s app ecosystem control.
