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. FEATURES - Generate unique keyboard codes with built-in checksum validation - Full keyboard support: letters, numbers, symbols, and shift - Decode mode: paste scrambled text to read it in plain language - Create keyboard groups to organize codes for different conversations - Custom group avatars from your photo library - Guided tour to get you started quickly - Works entirely offline UNLOCK MORE KEYBOARDS Scrombler includes one keyboard slot for free. Upgrade with a single lifetime purchase to unlock additional keyboard identities — perfect for keeping separate codes for different friend groups, teams, or conversations.

Encode Keyboard lets you encode and decode text in the app or directly from a custom iOS keyboard. TYPE, CONVERT, CONTINUE • Type in a supported text field, choose Encode or Decode, then select a codec • Tap Convert to replace the current line before the cursor • Undo the last conversion instantly • Switch between English and Vietnamese input TWELVE FORMATS, HONEST LABELS • RFC 4648 Base64, Base64URL, Base32, and Base16/Hex • RFC 3986 URL Percent and International Morse • UTF-8 Binary as an educational app profile; ROT13 as a classic convention • Emoji, Kaomoji, Leetspeak, and your own Personal Code for expression CREATE AND LEARN IN THE APP • Convert text with one clear direction-and-codec flow • Copy, share, or save a result; revisit favorites and recent history • Learn all 12 formats with specification sources, canonical examples, practice, and quick checks • Create, import, and export custom Emoji mappings and Personal Codebooks PRIVATE BY DESIGN All transformations run on device. No account or Full Access is required. There are no ads, analytics, or subscriptions. The keyboard has no network access and does not collect what you type. IMPORTANT Encoding is not encryption. Do not use these formats to protect passwords or sensitive information. Byte-based standard formats, Binary, and ROT13 can restore valid text exactly. Morse may normalize accents, case, and spacing. Emoji, Kaomoji, Leetspeak, and Personal Code are approximate or require the same codebook. Third-party keyboards are unavailable in secure text fields and some app-specific fields because of iOS restrictions.
