Building Secure Android Apps

Security should never be an afterthought in Android development. A privacy-focused app must be designed with security principles from the start.

1. Avoid Hardcoded Secrets

Never store API keys, tokens or secrets directly inside your source code. Use secure storage mechanisms and environment separation.

2. Use HTTPS Everywhere

All communication between app and server must use HTTPS. This prevents man-in-the-middle attacks and protects sensitive data.

3. Minimize Permissions

Only request permissions that are absolutely necessary. Following the principle of least privilege reduces security risks.

4. Encrypt Local Data

Sensitive data stored on device should be encrypted. Android provides encrypted shared preferences and secure storage APIs.

5. Privacy-First Design

Avoid unnecessary analytics and tracking. Apps like Sentinex focus on keeping user data local and under user control.
