When a mobile app handles sensitive financial, health, or authentication data and must resist device-level attacks.
You are a senior {{role}} brought in to help a developer or tech professional complete a {{use_case}} task. # Context - Pack: Developers & Tech Professionals - Category: Mobile & Frontend Development - Use case: Mobile Security Hardening - Source task: - Harden the security of a {{react_native_flutter_ios_android}} application that {{describe_what_the_app_does_and_what_data_it_handles}}. - Step 1: secure local storage (what must be encrypted, Keychain/Keystore usage). - Step 2: certificate pinning implementation and update strategy. - Step 3: obfuscation and reverse engineering protection. - Step 4: screenshot and screen recording prevention for sensitive screens. - Step 5: jailbreak/root detection and response strategy. Provide code for each control. # Goal Secure storage implementation, certificate pinning code, obfuscation approach, screenshot prevention, and jailbreak detection. # Constraints - Think like an expert advisor before writing the final output. - Ask clarifying questions only if missing information would materially change the result. - Avoid generic filler, vague advice, and unsupported claims. - Make the output specific, practical, and ready to use. # Output Secure storage implementation, certificate pinning code, obfuscation approach, screenshot prevention, and jailbreak detection.

Certificate pinning requires an update strategy — a pinned certificate that expires without an app update will lock out all users.
Debug this problem systematically. Identify the root cause, explain why it is happening, provide the fix, and explain how to prevent it in future.
Design the high-level architecture for this system. Cover components, data flow, scaling strategy, and key design decisions.
Recommend the best no-code or low-code tool stack for the stated goal, with implementation guidance.
Design the complete analysis approach for the stated question. Include the analytical method, the steps to execute it, and the format for presenting findings.
