Историческую версию User Dictionary Cache можно получить на Android
Ваша задача состоит в том, чтобы найти секретную информацию из базы данных пользовательского словаря.
Information that is cached may become accessible to other applications, and certainly becomes accessible if the device is found or stolen by a third party. Words entered by a user via the keyboard are stored in the Android user dictionary for future auto-correction.
The user dictionary is available to any app without requiring any permission and this could lead to sensitive data being leaked.
