Nihongo Sensei is designed to collect as little data as possible. This policy explains exactly what the app does and does not do.
Your progress, preferences, mastery levels, and quiz statistics are stored locally on your device and are never transmitted to us for any study or personalization purpose.
We do not use analytics, advertising, or third-party tracking SDKs of any kind.
The app does not require account creation, login, or any personal information to use it.
