📝 About this app
==Sino Korean Keyboard does NOT collect any private information==
The warning message that pops up when you first install this keyboard is from Google, warning you about potential danger in installing third-party apps, and it shows up whenever you install ANY keyboard on your device. Sino Korean Keyboard NEVER collects any information whatsoever, private or not, so please don't worry about your private information being stolen.
==Thank you for your reviews==
I would really appreciate any reviews whether a star or 5 stars. For those of you rating it a 1 star, please please send me an e-mail at fancyydk@gmail.com with your reason, so I can improve it for future releases. Thank you!
==Description==
This is a Korean IME keyboard that lets you type in Sino Korean (Chinese characters used in Korea) just as you would on a PC. The number keys are placed along with the character keys, so it's very convenient to type numbers and characters at the same time.
This is a free version with limited features. For instance, when a Korean character is typed and the Chinese key is pressed, three Chinese characters are shown at once, even though there may be more than three corresponding characters. To view other characters, you have to keep pressing the Chinese key until you find the character that you're looking for.
If you want a keyboard that lists all the possible Chinese characters for a Korean character, and that which has commonly used keys placed at more convenient places, please buy the paid version of this keyboard.
If you encounter a problem, please email me at fancyydk@gmail.com and I will try to fix the problem as soon as possible.
Thank you for your support and please look forward to updates and newer versions.
