Protecting data on the device and over the network
Most Android security failures come down to a few basics done poorly: secrets stored in plain text, weak transport security, or keys handled carelessly. We build on the platform's own protections — the Android Keystore for key material, hardware-backed crypto where available, and encrypted storage for anything sensitive.
Data in transit gets the same care: modern TLS, and certificate pinning where the threat model calls for it. The principle throughout is to store as little sensitive data as necessary and to protect what you do keep.
- Keys generated and stored in the Android Keystore, hardware-backed when supported
- Encrypted local storage for sensitive data (e.g., EncryptedSharedPreferences, SQLCipher-style approaches)
- TLS for all network traffic, with certificate pinning where warranted
- Secure authentication flows and safe token/session handling
- Biometric unlock (fingerprint/face) via the platform BiometricPrompt where useful
- Data minimization so you're not storing sensitive information you don't need
Hardening the app and the release
Beyond data, the app itself needs hardening: keeping secrets out of the client, obscuring the code enough to slow casual reverse engineering, and locking down the permissions and components the app exposes. We also plan for the parts security teams check, like backup behavior and inter-app communication.
Security is ongoing, not a one-time checkbox. We build with current best practices and can run a focused review, but honest security also means keeping dependencies patched and revisiting the threat model as your app grows.
- Code shrinking and obfuscation (R8/ProGuard) to raise the bar for tampering
- No hardcoded API keys or secrets shipped in the client
- Least-privilege permissions and locked-down exported components
- Secure defaults for backups, logging, and debug flags in release builds
- Dependency scanning so known-vulnerable libraries get patched
- Optional security review against OWASP Mobile guidance for your app

Frequently asked questions
Is the Android Keystore enough to keep our keys safe?
The Keystore is the right foundation — on supported devices it keeps key material in hardware where apps can't extract it. But real security is the whole design: how you use those keys, how you store data, and how you handle authentication. We build the full picture, not just key storage.
Do we need certificate pinning?
It depends on your threat model. Pinning defends against certain man-in-the-middle attacks but adds operational care when certificates rotate. For apps handling sensitive data it's often worth it; for others it can be overkill. We'll recommend based on what your app actually does.
Can you make our app impossible to reverse engineer?
No honest developer will promise that — any client app can be inspected given enough effort. What we can do is keep secrets off the device, obfuscate the code, and design so that compromising one app doesn't compromise your users, which is the security that actually matters.
