Privacy Policy
This page explains what information YakoGaku stores, why it is used, and how it supports your learning progress and account features.
What we collect
Depending on how you use YakoGaku, we may collect account and gameplay information such as your email address, display name, player ID, profile settings, learning progress, coins, rank progress, mining data, friends, chat messages, and community-library posts you publish.
We may also store technical information needed to keep the app working, such as session data and browser-based local progress.
How we use your information
- To create and maintain your account.
- To save your learning progress and sync it across devices.
- To power social features like friends, chat, profile identity, and community-library publishing.
- To improve app stability, fix issues, and support the service.
Where data is stored
YakoGaku stores some data locally on your device and some account-related data in hosted backend services so your profile and progress can persist across sessions and devices.
Social features may also store friend, message, and public community-post data so those features can work correctly.
What other players can see
Other players may be able to see your display name, player ID, profile information you choose to show, the messages you send through chat, and any community-library posts you publish.
Please avoid sharing private or sensitive information in social features.
Children and parent guidance
If YakoGaku is used by a child, a parent or guardian should review the service and help decide what information is appropriate to share.

Questions about privacy can be sent to contact@yakogaku.com.
This is a practical starter policy for the current version of YakoGaku and should be reviewed as the app grows.
