We do not provide third parties with personally identifiable information. We take great care in managing personal information and treat it as listed below.

The setting screen of the app has a function to send comments, requests and bug reports via email. To help solve the problem, device information such as OS version, mobile or tablet model, app version etc. is sent.

In addition, in order to improve the convenience of the app, we pay close attention to areas that can not be identified anonymously and analyze access. For example, when the application crashes, we send anonymously the part where it crashed, and it is useful for quick correction of the bug.

In addition, we analyze device and application version usage rates, usage rates of specific functions, etc. to help improve the apps. (For example, give priority to improvement of the function being used more)
