Privacy Policy

OAZUKE app

This policy describes how the iOS and Android versions of the app "OAZUKE" (the "App") handle user information. The provider of the App is referred to below as the "Operator".

1. Information stored on your device

The following information is stored on your device. Unless you use the friends feature, the content itself is never sent to any external server. However, records of actions such as starting or completing an OAZUKE session are sent for the usage analysis described in section 4.

This information is deleted from your device when you delete the App.

On Android, only if you allow it in your device settings, the App uses "Usage access" to read your screen time, your most-used apps, and the list of installed apps. This is used only to show you your screen time during onboarding, and, for "apps allowed during OAZUKE", to check whether an app opened during a session is one you allowed. If you also allow "Display over other apps", the App shows a reminder screen to bring you back to OAZUKE when you open an app you did not allow during a session. This information is processed only on your device and is never sent to the Operator's servers or any third party.

2. Information sent when you use the friends feature

Only when you use the friends feature, the following information is stored on servers managed by the Operator and made visible to people you have mutually accepted as friends.

Icons and photos are stored on external cloud storage and served from URLs that are impractical to guess. If you remove or block a friend, the content no longer appears in their app.

If you never use the friends feature, none of this information is created.

3. Information sent through the contact feature and surveys

Only when you use the in-app contact feature, the following information is stored on servers managed by the Operator.

This information is used solely to respond to your inquiry and to notify you of replies. The text of your message, your anonymous user ID, the display language, and the type of device are also forwarded to a chat service (Slack) that the Operator uses to handle inquiries.

Only when you answer an in-app survey, your answers and your usage at the time (free or Premium, number of OAZUKE sessions, days since installation, current streak, display language, app version, and device type) are stored on servers managed by the Operator together with your anonymous user ID. This is used only to improve the App.

4. Analytics

To improve the App, we use Google Firebase (Google Analytics for Firebase, Crashlytics, and Performance Monitoring) to collect the following.

This information is used only for statistical analysis and contains nothing that identifies you personally, such as your name or email address.

5. Advertising

The App may show advertising from Google AdMob when used for free. No advertising is shown if you have a Premium subscription or purchase.

To deliver advertising, AdMob may obtain information such as your device's advertising identifier (the IDFA on iOS, the advertising ID on Android). On iOS, we ask for your permission in the App before this identifier is used. If you decline, you can still use every feature of the App; the advertising you see simply will not be tailored to your interests.

On iOS, you can change this permission at any time in Settings > Privacy & Security > Tracking on your device. On Android, you can delete or reset your advertising ID in the ads section of your device settings (for example, Privacy > Ads, depending on your device).

On Android, depending on where you live, we ask for your consent regarding advertising in the App as required by law.

For how AdMob handles information, please see Google's policy.

6. Sharing with third parties

We do not share collected information with any third party except where required by law. However, external companies may obtain information for the analytics and advertising purposes described in sections 4 and 5.

7. Service providers

The App uses cloud services provided by external companies in order to operate the friends feature, the contact feature and surveys, manage in-app purchases, analyse usage, and deliver advertising. We contractually require these companies to protect information to a standard equal to or higher than this policy.

What these companies receive is limited to an anonymous user ID and the information described in this policy. No information that identifies you personally, such as your name, email address, or phone number, is passed to them.

8. Purchases

Purchases in the App are processed through Apple's App Store on iOS and through Google Play on Android. The Operator never receives your credit card number or other payment details.

In order to correctly reflect what you have purchased, we manage an anonymous user ID together with your purchase details (the item purchased and the expiry of your subscription).

9. Notifications

The App may use push notifications, for example to let you know when your OAZUKE session is complete. You can turn notifications off at any time in the App's settings or in your device settings.

10. Deleting your information

Information on your device is removed by deleting the App.

Information stored on our servers through the friends feature (your name, introduction, icon, fridge decorations, activity summary, and push notification token) is not removed automatically when you delete the App. If you would like it deleted, please contact us via the in-app contact feature. We will delete it within 14 days and confirm once it is done.

Information sent through the contact feature or surveys can be deleted on request in the same way.

You can also remove or block a friend at any time from the friends list in the App.

11. Changes to this policy

This policy may be updated from time to time. Significant changes will be announced in the App or on this page.

12. Contact

For questions about this policy, please use the in-app contact feature.
