Hinbun Privacy Policy
Last updated: September 2026
This policy explains how information is handled in the Hinbun language-learning mobile application and on this website. Hinbun does not sell personal data.
Information we collect
Hinbun collects the information needed to provide the app, keep your learning progress available across sessions and improve the learning experience. The categories below describe what this can include.
Account information
If you create an account, we process the information you provide, such as your email address and authentication details. This is used to identify your account and give you access to your content.
App usage and analytics
We may process aggregated or pseudonymised usage information, such as which screens and lessons are opened and whether a feature works as expected. This helps us find issues and decide what to improve.
Learning progress
Your progress, such as completed lessons, saved words and review history, is stored so that you can continue where you stopped.
Device and technical information
We may process technical information such as device type, operating system version, app version, language settings and error or crash reports.
How information is used
Information is used to operate and secure the app, to save your progress, to provide subscription access, to respond to support requests and to improve the app’s content and stability.
Third-party services
Hinbun may use third-party services that are necessary to operate the app, such as authentication, analytics, cloud infrastructure and hosting, translation, speech recognition, text-to-speech, AI functionality and subscription or payment infrastructure. These providers process information on our behalf or, where applicable, as independent controllers under their own terms.
AI-powered features
Some features use AI or speech processing. When you use them, the relevant input, such as text or a short audio recording, may be sent to a processing provider so the feature can return a result. This input is used to deliver the feature you requested.
Data retention
Information is kept for as long as needed to provide the app and your account, or for as long as required by applicable law. When information is no longer needed, it is deleted or anonymised.
Security
We take reasonable technical and organisational measures to protect information against unauthorised access, loss or misuse. No method of transmission or storage is completely secure.
Children’s privacy
Hinbun is not directed at young children. If you believe a child has provided personal information to us, contact us and we will review and remove it where appropriate.
User rights
Depending on where you live, you may have the right to request access to your personal information, correction, deletion, restriction or a copy of it, and to object to certain processing. To make a request, contact us at the address below.
Changes to this policy
We may update this policy as the app develops. The updated version is published on this page with a new date.
