Overview
Kana Tutorial is intended to be a simple learning app for practicing Japanese hiragana and katakana.
Data CHKA Production receives
Kana Tutorial does not require an account and is not intended to send personal information, study activity, or app usage analytics to CHKA Production.
Analytics, advertising, and tracking
Kana Tutorial does not include analytics SDKs, advertising SDKs, tracking pixels, or third-party marketing tools.
Network access and external links
Kana Tutorial is intended to work without sending study activity or personal information to CHKA Production servers. The app may include links to external learning resources, such as Wikipedia, which open outside the app in your browser or system web handler. External websites are governed by their own privacy policies.
Data stored on your device
The app stores learning progress locally on your device. This may include the selected deck, study mode, card learning state, timestamps, and progress values. This local data is used only to provide app functionality and is not intentionally transmitted to CHKA Production.
App stores, backups, and operating systems
Apple, Google, and your device operating system may process information related to installing, updating, purchasing, backing up, or using apps. Depending on your device settings, the operating system may include local app data in device backups. Their processing is governed by their own privacy policies and account settings.
Email support
If you contact CHKA Production for support, the information you include in your email will be used to respond to your request and maintain support records as needed.
Children's privacy
Kana Tutorial is a learning app, but it is not intended to knowingly collect personal information from children.
Changes
This policy may be updated if the app's features, SDKs, data handling, or support process changes. The updated date will be revised when changes are made.
