Information collected when you use the Apps
In the Apps, we may collect the following information depending on how you use them, in order to provide functions and services.
- Account information (email address, nickname, information for authentication, and the like, including cases where you authenticate using an external account such as Google or Apple)
- Camera and photo information (images captured or selected for the functions of each App, such as worksheets, answer sheets or handwritten works)
- Learning and usage information (learning and usage history, the results and evaluations thereof, content you enter or create, and the like)
- Device and log information (OS and device type, device identifiers, app version, usage logs, diagnostic (crash and performance) information, tokens for push notifications, and the like)
- Billing and purchase information (the status of purchases and use through stores such as the App Store and Google Play. Payment information such as credit card numbers is managed by each store, and the Company does not collect or retain it)
- Location information (in some functions, we may collect it based on your device settings)
- Profile information (such as age group, gender, occupation, purpose of use and interests that the user optionally registers, and the image set as the profile. The image is either one created by our function or a photo selected by the user)
We use this information for the purposes of providing the Apps’ functions and services, verifying identity and managing accounts, providing and improving the learning experience, managing billing and purchases, sending important notices and support communications, and conducting research and analysis for quality improvement. The information collected and the purposes of use may differ depending on each app; in such cases, we will provide separate notice within each app.
Information obtained in the course of your use of the Services is used to improve the quality of the Services and of other learning- and education-related services we provide, to improve functions, teaching materials and content, to improve the accuracy of assessment and analysis, and to research, develop, evaluate and verify new functions, services and technologies.
For the purposes described above, the Company may create and use analytical data that has been separated from its association with the account so as to reduce the possibility of identifying an individual.
Images captured and content entered may be processed by external cloud and AI services engaged by the Company, in order to provide functions and to perform analysis. We appropriately supervise such service providers in accordance with this Policy and applicable laws.
Only where the user uses the function that creates a profile image, we send the age group, gender, occupation, purpose of use, interests, favorite color and appearance-related items that the user has optionally registered, together with any request entered by the user (for example, “wears glasses”), to OpenAI for the purpose of creating that image. We do not send name, e-mail address, telephone number, area of residence, income range, family composition or frequency of use.
Images captured or selected in the Apps
Images captured or selected are used to provide functions, to improve the accuracy of assessment and analysis, and to research, develop, evaluate and verify services and technologies, and are retained for the period necessary for those purposes.
About advertising (in some Apps)
In some of the Apps (such as free plans), we may use third-party ad-delivery services, including Google “AdMob”, to deliver advertisements. Accordingly, information such as advertising identifiers may be collected and used by those providers for ad delivery and effectiveness measurement. The display of interest-based (personalized) advertising can be limited through your device settings (such as limiting ad tracking or resetting your advertising ID).
Access information and Cookies
To improve the convenience of our services and understand how they are used, we may collect access information (such as browser and device type, IP address, the pages or screens viewed or used, and the referrer) using Cookies on the Site and device identifiers and the like in the Apps. This information is processed statistically and does not, by itself, identify any specific individual.
You can stop this collection by disabling Cookies in your browser settings on the Site, or through your device and OS settings in the Apps. If you disable it, some functions may become unavailable.
ManagementManagement of Personal Information

After receiving a request to delete an account, the Company deletes the account and the information directly associated with the account.
Processed analytical data (data separated from its association with the account so as to reduce the possibility of identifying an individual), backups, transaction records, records kept for fraud prevention and the like may be retained after deletion within the scope of the purposes of use described above.
