Overview

• Former product manager Samujjal Purkayastha filed claims alleging Meta continued identifying iPhone users who denied App Tracking Transparency consent by linking data across platforms.
• The filing alleges a closed internal team used deterministic matching to connect identifiable information in ways that would violate Apple’s policies.
• Purkayastha also claims Meta inflated the performance of its Shops Ads by using gross sales figures that included taxes and shipping, allegedly overstating results by up to 19%.
• The filing says internal reviews confirmed inflated metrics and alleges undisclosed subsidies for test campaigns, while Meta denies wrongdoing and says his dismissal was unrelated.
• The tribunal is not expected to rule on the full case until 2026, and separate class‑action litigation over alleged tracking workarounds remains active.
