Scrombler

Send secret messages only your friends can read. No servers, no accounts — just share a code and start typing in cipher.

Scrombler turns your keyboard into a cipher machine. Type normally and your messages come out encrypted — only people with your shared keyboard code can decode them.

HOW IT WORKS

1. Open Scrombler for a unique keyboard code.
2. Share the code with a friend, group chat, or anyone you want to communicate with privately.
3. Switch to the Scrombler keyboard and type. Every letter, number, and symbol is remapped into a scrambled output.
4. Your recipient enters the same code in their copy of Scrombler, and their keyboard can decode your messages instantly.

No accounts. No servers. No sign-ups. Just a code between you and the people you trust.

BUILT FOR PRIVACY

Scrombler was designed from the ground up with privacy as the priority:

• Zero network connections — the app never contacts any server, ever.
• No keystroke logging — your typing is never recorded or monitored.
• No analytics or tracking — we don't collect any data about you or how you use the app.
• Everything stays on your device — cipher mappings, group settings, and avatars are stored locally only.

The keyboard requests Full Access solely so the extension can read your saved cipher configurations via a shared on-device container. Nothing leaves your phone.

DETERMINISTIC ENCRYPTION

Every keyboard code produces the exact same cipher mapping on every device. This means two people with the same code will always get the same scrambled keyboard — no syncing, no cloud, no middleman.
