ScreatGenix — Secret Message Encoder

ScreatGenix is a privacy-first secret-messaging app for Android, built natively in Kotlin. It lets anyone turn an ordinary message into something only the intended person can read — and then share it as text, a QR code, or hidden inside an innocent-looking image.

The app is built around real security. In its Secure mode, messages are protected with AES-256-GCM encryption, with the key derived from the user's password using PBKDF2 — the same class of encryption trusted by banks and messengers. For lighter, fun use, it also offers classic ciphers like Caesar, Morse, emoji and reverse, so friends and children can enjoy simple secret codes too.

What makes ScreatGenix stand out is its focus on genuine privacy and clever features. It requests no internet permission at all, stores nothing on the device, and blocks screenshots. A standout feature is image steganography — a secret message can be hidden invisibly inside a normal photo. There is even a decoy mode, where a fake password reveals a harmless fake message, so no one can tell whether a real secret exists.

Key features:

• AES-256 encryption — password-protected, bank-grade secure messages.

• Fun ciphers — Caesar, Morse, Emoji and Reverse for casual use.

• QR codes — turn a secret into a QR to scan and decode.

• Hidden-in-image — steganography to hide a message inside a photo.

• Decoy mode — a fake password shows a fake message, hiding the real one.

• Share & paste — send encoded text through any app.

• No internet permission, nothing stored, screenshots blocked — serious privacy.

Engineered to be tiny and trustworthy — the entire app is around 80 KB, with no account, no ads, and no network access whatsoever.
