Ensure strong encryption, follow secure coding practices, and limit data storage. Regular security audits and compliance with privacy regulations can also help protect user data.

I’d implement strong encryption, enforce strict access controls, and conduct regular security audits. Educating users on safe practices and keeping the app updated with the latest security patches would also help prevent data leaks and unauthorized access.

1. Regularly Update Security Why: Outdated libraries, frameworks, or OS vulnerabilities (e.g., unpatched Android/iOS exploits) are common entry points for attackers. 2. Encrypt Sensitive Data Why: Unencrypted data—whether stored locally or sent over the network—can be intercepted or extracted from a compromised device. 3. Conduct Penetration Testing Why: Proactive testing finds weaknesses (e.g., SQL injection, insecure storage) before attackers do. 4. Secure Authentication and Session Management Why: Weak login or session handling (e.g., long-lived tokens) can expose user data. 5. Minimize Data Exposure Why: The less data your app stores or sends, the less there is to leak.

Preventing data leaks in a mobile app starts with strong security measures. I enforce end-to-end encryption, secure APIs, and strict access controls to protect user data. Regular security audits and penetration testing help identify vulnerabilities before they become threats. Educating users on safe practices, like enabling multi-factor authentication, adds another layer of defense. By combining robust security protocols with proactive monitoring, we safeguard sensitive information and build user trust.
