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 conceals the cipher using tile division and shuffling.
- Quiz-like element: The generated key is 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 (up to 5 saved).
- Save decryption keys: Save frequently used decryption keys for specific individuals with names (up to 5 saved).
- History management: Save up to 50 created ciphertexts and mosaic images to 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: Those who enjoy solving puzzles and those who want to exchange secrets with friends (late teens and up).

Note:
- The ciphers in this app are for fun and learning purposes only. Do not use this for protecting confidential information.
- This ad-supported version displays AdMob ads (banner ads and full-screen ads during encryption creation).
