Apple expands App Store on-device review for privacy-preserving subscriptions

Tech · 4 min read

At WWDC 2026 Apple announced an on-device subscription verification API that runs locally on users’ devices to confirm active subscriptions and trial eligibility without requiring a backend call to the App Store. The API uses short-lived tokens and an attestation mechanism to maintain trust between apps and the App Store while keeping billing metadata off developers’ servers.

The new mechanism is designed for low-bandwidth and offline scenarios, enabling apps to check subscription entitlements and present appropriate UI even when connectivity is poor. Apple emphasizes that developers must still support server-side receipt validation for reconciliation and fraud detection, but the on-device flow reduces surface area for user data exposure.

Designers and product teams are encouraged to update onboarding and paywall patterns to take advantage of instant local checks. Apple published Human Interface Guidelines updates with examples for smooth transitions between offline entitlement states and full-account experiences.
