Information collected by the application

Data collected by the application is stored in the device’s internal storage. Data is encrypted and other security measures are taken.

About Data Backup

The app also saves data to the application area in Google Drive through the user’s Google account for the purpose of data backup and restore (restoration).

This backup and restore will not be performed unless the user wishes to do so (or more correctly, unless the user agrees to it by tapping a button).

The Google API is used for the backup sequence of operations, and App’s use and transfer to any other app of information received from Google APIs will adhere to Google API Services User Data Policy, including the Limited Use requirements.

Purpose of Data Use

The data collected and stored by the application is used only within the application. Specifically, it is used to improve the user experience. It will not be used in any other way.

The data collected and saved by the app is stored in the internal storage of the user’s device and can be deleted from the app information in the device.

Also, if backup data is saved, it can be deleted from the settings screen within the app.

If you deleted the app without deleting the backup data, please install the app again and delete it from the settings screen within the app.
