What is this?

This is a Claude Code specialized agent that audits your Flutter app for App Store and Google Play compliance before you submit. It catches the issues that cause 80% of rejections — privacy manifests, missing permissions rationale, ATT timing, metadata gaps, API level mismatches — so you don't waste days in review limbo.

Built from hard-won experience shipping Flutter apps through both stores, updated for the April 2026 deadlines.

What it checks

Apple App Store

• Privacy Manifest (PrivacyInfo.xcprivacy) — required reason APIs, data collection declarations
• App Tracking Transparency (ATT) — timing, UI visibility, NSUserTrackingUsageDescription
• Third-party SDK signatures and privacy manifests
• iOS 26 SDK / Xcode 26 build requirement (April 28, 2026 deadline)
• Age rating questionnaire (updated 13+/16+/18+ categories)
• Sign in with Apple + account deletion flow
• In-App Purchase configuration and StoreKit 2
• App Privacy labels accuracy vs actual data collection
• Info.plist permission descriptions (camera, location, photos, NFC, Bluetooth...)
• Metadata validation (screenshots dimensions, keyword limits, subtitle length)
• AI/automation disclosure requirements
• Export compliance (encryption)

Google Play Store

• Data Safety section completeness and accuracy
• Target API level (Android 15 / API 35+ as of Aug 2025)
• AAB format (APK no longer accepted)
• Photo & Video permissions policy (READ_MEDIA_IMAGES/VIDEO declarations)
• Play Integrity API (SafetyNet replacement)
• Age-Restricted Content policy
• Privacy policy hosted online (not PDF)
• AndroidManifest.xml permission audit
• Proguard/R8 rules validation
• App signing configuration

Flutter-Specific

• PrivacyInfo.xcprivacy in ios/Runner/ — auto-generated vs custom
• Plugin permission injection audit (AndroidManifest.xml merged permissions)
• pubspec.yaml version/build number validation
• Localization completeness (lib/l10n/*.arb files)
• Release build configuration (obfuscation, tree-shaking)
• Fastlane integration checks (metadata, screenshots, delivery)

Why this exists

Every Flutter developer knows the pain:

1. You build your app
2. You submit to the stores
3. You get rejected for something you didn't know about
4. You fix it, resubmit, wait 24-48h
5. You get rejected for something else
6. Repeat 3-8 times

This agent runs the full compliance gauntlet locally in seconds, catching issues before they cost you days.
