Apple is facing a £2 billion ($2.7 billion) lawsuit in the UK over its App Tracking Transparency (ATT) rules, with app developers accusing the iPhone maker of using its market power to impose unfair restrictions on third-party businesses.
The lawsuit was filed at London’s Competition Appeal Tribunal on Thursday and adds to growing regulatory pressure on Apple over the way it handles user tracking and advertising data. At the heart of the case is a feature Apple introduced in 2021, which the company says was designed to give users greater control over their personal information.

Developers Challenge Apple’s Privacy Rules
Apple’s App Tracking Transparency feature requires apps to ask users for permission before tracking their activity across other companies’ apps and websites. The company has consistently defended the system as an important privacy measure that gives consumers more control over how their data is used.
However, lawyers behind the latest lawsuit argue that Apple’s approach goes beyond protecting user privacy.
They claim Apple has imposed stricter tracking requirements on third-party developers while applying different rules to its own services. According to the legal action, this could give Apple’s advertising ecosystem an advantage over competitors whose businesses depend heavily on targeted advertising.
The lawsuit is being led by Ann Pope, a former senior official at Britain’s Competition and Markets Authority (CMA). Pope said Apple’s policies had caused “very significant harm” to businesses that rely on the company as a gatekeeper to reach millions of iPhone and iPad users.
“This action is important to protect the rights of British businesses that depend on Apple,” Pope said, arguing that companies should be subject to fair and consistent rules.
Why App Tracking Matters to Developers
Advertising tracking plays a crucial role in the business models of many free apps and digital services. Developers use information about users’ interests and activity to help advertisers deliver more relevant advertisements.
Apple’s ATT framework changed that model by requiring users to actively grant permission for cross-app and cross-website tracking. If permission is denied, developers can face significant limitations in collecting data that can be used for targeted advertising.
While privacy advocates have welcomed greater user control, advertising companies and developers have argued that Apple’s system can make it harder for them to compete.
The latest lawsuit therefore highlights a broader tension in the technology industry: whether privacy-focused policies can also create competitive advantages for the companies that control major digital platforms.
Apple Under Growing Regulatory Pressure
The UK case is not the first time Apple’s tracking policies have attracted scrutiny from competition regulators.
The company has faced investigations and challenges across Europe, particularly in Germany. Last month, Apple agreed to changes to its app data consent rules following pressure from Germany’s competition authority.
German regulators had previously accused Apple of abusing its market power through its tracking framework. Meta, publishers, advertisers and app developers had also criticised the system, arguing that it could negatively affect businesses that depend on advertising-based revenue.
The German case demonstrates how Apple’s privacy policies have become intertwined with wider antitrust concerns. Regulators are increasingly examining whether technology giants can introduce rules that appear to protect consumers while potentially disadvantaging businesses that compete with their own services.

A New Battle Over Apple’s App Store Power
Apple has not yet commented on the new UK lawsuit. The company has previously maintained that App Tracking Transparency provides important privacy protections for users.
The £2 billion claim could nevertheless become another major test of Apple’s control over its ecosystem. As regulators and businesses increasingly question the power of large technology platforms, the case could help determine how much freedom companies such as Apple have to set rules for developers operating on their platforms.
For Apple, the challenge is no longer simply about whether users should have control over their data. It is also about whether the rules created in the name of privacy are applied fairly across the entire ecosystem.
If the lawsuit succeeds, it could potentially have significant financial and competitive consequences for Apple while strengthening calls for greater oversight of platform rules in the UK and beyond.
