+alwaysApply: true
+---
+
+# Security Standards — {{PROJECT_NAME}}
+> **Pillar 5**: Security is an always-on rule, not just a reactive agent.
+> These rules apply to EVERY file write, regardless of feature or context.
+
+## Credential & secret management
+- **NEVER** hardcode API keys, tokens, or secrets in source code
+- **NEVER** commit `.env` files — use `.gitignore` and document required vars in `.env.example`
+- API keys belong in: flavored `--dart-define` build args, or a secrets manager (e.g. AWS Secrets)
+- Use `flutter_secure_storage` for tokens/credentials — **NEVER** `SharedPreferences` for sensitive data
+- Obfuscation: enable `--obfuscate --split-debug-info=build/debug-symbols/` for release builds
+
+## Authentication & sessions
+- JWT/session tokens: stored in `flutter_secure_storage`, never in `SharedPreferences` or local DB
+- Implement token refresh with retry logic — never let a 401 show a raw error to the user
+- Certificate pinning: required for production builds on {{AUTH}} — use `dio_pinning_interceptor`
+- Biometric re-auth: require for any transaction > defined threshold
+
+## Data & privacy
+- **NEVER** log PII (names, emails, phone numbers, addresses) to console or crash reporters
+- Sanitize all user inputs before sending to backend
+- Use `SensitiveWidget` wrapper to exclude screens from screenshots / app switcher thumbnails
+- Comply with platform privacy requirements: iOS `NSPrivacyAccessedAPITypes`, Android permissions
+
+## Network security
+- All API calls use HTTPS — no http:// in production
+- Validate SSL certificates — never bypass with `badCertificateCallback: (_,_,_) => true`
+- Add a timeout to every HTTP call: `connectTimeout: Duration(seconds: 10)`
+- Rate-limit sensitive endpoints: auth, OTP, password reset
+
+## Dependency security
+- Run `dart pub outdated` monthly — flag packages with known CVEs
+- Never use a package with <100 pub points without explicit tech lead approval
+- Pin critical security packages to exact versions in `pubspec.yaml`
+
+## Secure coding patterns
+```dart
+// ✅ Correct: secure token storage
+final storage = FlutterSecureStorage();
+await storage.write(key: 'access_token', value: token);
+
+// ❌ Wrong: SharedPreferences for sensitive data
+final prefs = await SharedPreferences.getInstance();
+prefs.setString('access_token', token); // NEVER do this
+
+// ✅ Correct: PII-safe logging
+logger.info('User authenticated: userId=${user.id}'); // ok — id, not email
+logger.debug('Payment processed: orderId=$orderId');  // ok — no card data
+
+// ❌ Wrong: PII in logs
+logger.info('Login: email=${user.email}, phone=${user.phone}'); // NEVER
+
+// ✅ Correct: --dart-define for secrets (build arg, not in code)
+// flutter build apk --dart-define=API_KEY=$API_KEY
+const apiKey = String.fromEnvironment('API_KEY'); // acceptable
+
+// ✅ Correct: certificate pinning with Dio
+(dio.httpClientAdapter as IOHttpClientAdapter).createHttpClient = () {
+  final client = HttpClient();
+  client.badCertificateCallback = (cert, host, port) => false; // strict
+  return client;
+};
+```
+
+## Deep linking & intent security
+- Validate all incoming deep link parameters — never trust raw URL params
+- Use `app_links` package for verified deep link handling
+- Restrict URL schemes to known patterns — reject unknown schemes
+- For OAuth callbacks: validate `state` parameter to prevent CSRF
+
+## Storage security
+- Encrypt locally cached sensitive data using `hive` with `HiveAesCipher`
+- Clear sensitive data from memory after use (set to null, trigger GC)
+- Do NOT cache auth tokens in network layer (no `dio_cache_interceptor` for auth endpoints)
+- Use `SecureRandom` for nonce/token generation — never `Random()`
+
+## Code obfuscation & binary protection
+```yaml
+# android/app/build.gradle — release config
+buildTypes {
+  release {
+    minifyEnabled true
+    shrinkResources true
+    proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
+  }
+}
+```
+```bash
+# Flutter release build with obfuscation
+flutter build apk --release --obfuscate --split-debug-info=build/debug-symbols/
+flutter build ipa --release --obfuscate --split-debug-info=build/debug-symbols/
+```
+
+## Release checklist
+Before every production release, verify:
+- [ ] No hardcoded secrets (`grep -r "api_key\|secret\|password\|token" lib/`)
+- [ ] Debug flags disabled (`kDebugMode` guards on all debug-only paths)
+- [ ] Obfuscation enabled in release build config
+- [ ] Certificate pinning active and tested on both platforms
+- [ ] Crash reporter PII filters configured (Sentry `beforeSend`, Firebase `setConsentType`)
+- [ ] `flutter_secure_storage` used for all tokens — no `SharedPreferences` for sensitive keys
+- [ ] Network calls all HTTPS — scan for `http://` in lib/
+- [ ] Dependencies audited: `dart pub outdated --json | jq '.packages[] | select(.isDiscontinued)'`
+- [ ] Deep link parameters validated
+- [ ] App transport security / network security config reviewed
