Privacy Policy
Nihongo Sensei is designed to collect as little data as possible. This policy explains exactly what the app does and does not do.
Your study data stays on your device
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.
No tracking, no ads
We do not use analytics, advertising, or third-party tracking SDKs of any kind.
No accounts required
The app does not require account creation, login, or any personal information to use it.
Redeeming codes
If you enter an access code, the app sends only that code to our server to check whether it is valid. No identifier, email, account or device data is sent. The server stores nothing except whether the code is still available. Our hosting provider keeps a technical request log for 24 hours, which may include the IP address; we declare it for that reason. The app has no accounts, shows no ads, does no tracking, and works offline except for that one moment.
Canje de códigos. Si introduces un código de acceso, la aplicación envía únicamente ese código a nuestro servidor para comprobar si es válido. No se envía ningún identificador, correo, cuenta ni dato del dispositivo. El servidor no guarda nada salvo si el código sigue disponible. Nuestro proveedor de alojamiento conserva un registro técnico de las peticiones durante 24 horas, que puede incluir la dirección IP; lo declaramos por eso. La aplicación no tiene cuentas, no muestra anuncios, no hace seguimiento y funciona sin conexión salvo en ese único momento.
