Mobile Security

Priority: P0 (CRITICAL)

Standards for basic mobile security and PII protection.

Implementation Guidelines

• Secure Storage: Use flutter_secure_storage for tokens/PII. Never use shared_preferences.
• Hardcoding: Never store API keys or secrets in Dart code. Use --dart-define or .env.
• Obfuscation: Always release with --obfuscate and --split-debug-info. Note: This is a deterrent, not cryptographic protection. For sensitive logic, move to backend.
• SSL Pinning: For high-security apps, use dio_certificate_pinning.
• Root Detection: Use flutter_jailbreak_detection for financial/sensitive applications.
• PII Masking: Mask sensitive data (email, phone) in logs and analytics.

Reference & Examples
