Hinbun Privacy Policy

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

To understand how Hinbun is used and to improve it, we record how the app is used. This includes, for example, which screens and features you open, the steps of a lesson you complete or leave and whether an answer was correct, reading and listening progress, energy, streak and league changes, the subscription plan you choose, and the app version and language settings in use.

This information is linked to a pseudonymous account identifier. It is not linked to your email address or name. Usage events do not include the text you type or scan, the content of AI chat or practice conversations, your audio or your precise location, and the current version of the app does not collect advertising identifiers.

Session recordings. For some sessions, for example during the first days after you start using Hinbun, when the subscription screen is opened, and for a random sample of other sessions, we may record a visual reconstruction of the app screens and your taps so we can see where the app is confusing or does not work as expected. Text you type, AI chat and practice conversations, scanned documents and images, including profile photos, are masked and never appear in recordings. Recordings do not include audio.

Crash and error reports. If the app crashes or an error occurs, a report with technical details (such as the screen, device model, operating system and app version) is sent so we can fix the problem.

Your choice. You can turn off usage analytics and session recordings at any time in the app under Settings → Usage data. The app keeps working the same way when it is turned off. Crash reports are still sent so we can keep the app stable.

Legal basis. Where the GDPR applies, we process this information on the basis of our legitimate interest in keeping the app stable and improving it. You can object at any time using the setting above or by contacting us.

Retention. Analytics data is kept for up to 12 months and session recordings for a shorter period, after which they are deleted. When you delete your account in the app, the usage analytics and session recordings linked to your account are deleted as well. Basic app statistics and crash reports kept by Google Firebase are deleted automatically at the end of their retention period. You can also contact us to ask for deletion at any time.

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 process technical information such as device type, operating system version, app version, language and time zone settings, and crash and error 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.

For usage analytics and session recordings we use PostHog, with data hosted in the European Union. For crash reporting and basic app statistics we use Google Firebase (Crashlytics and Google Analytics for Firebase). Subscriptions are managed through RevenueCat together with Apple and Google. These providers process information on our behalf.

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.
