About this app

This is a "playable cipher" app using hiragana. Its official name is "Easy Cipher Messages (Secret Communication)".

Here's what you can do:
- Register a cipher code and send secret messages that only others can understand!
- Create countless patterns of cipher messages using 5 different cipher methods and sequence manipulations.
- You can even send images in fragments. Share memories only with those who know the code.

Main Features:
- Freely combine 5 ciphers: Tanuki cipher (character insertion), consonant conversion, Enigma dial, reverse reading, and rotation. You can also decide the application order, creating infinite variations even with the same sentence.
- Encrypt katakana and alphabet: Encrypt and decrypt not only hiragana but also mixed katakana and English text (excluding some ciphers).
- Image cipher: Turn photos into mosaic art. Completely hides with tile division + shuffle
- Quiz element: Generated keys are in a simple format like "1237 and 23 3123 4 55". The key itself can be used as the answer to a quiz.
- Save conditions: Save frequently used cipher combinations with names and recall them at any time (unlimited number).
- Save decryption keys: Save frequently used decryption keys for others with names (unlimited number).
- History management: Save up to 50 created ciphertexts and mosaic images on your device.
- Complete privacy: All processing is completed within the device. Input text and images are never sent externally.
- Offline operation: Usable without an internet connection (Kanji to Hiragana conversion is optional).

Target audience: People who like solving puzzles, people who want to exchange secrets with friends (late teens and up).
