DangoLoop Support

The first portion of each level is free, and words after that are shown as locked. The exact range is shown on the level screen and the purchase screen. Ads are shown in the free portion; holding a Paid Product unlocks every level and removes ads.

The level classification is an unofficial reconstruction based on publicly available study materials, and meanings and example sentences may contain errors. Email us the level, the word, the app language, and what is wrong; we will check it and include the fix in the next content update.

The originals of your study records are stored only on your device, not on the Company’s servers. They may be restored to a new device through the operating system’s device backup (Android Backup, iCloud Backup), but the Company does not guarantee that. A purchased lifetime license or subscription is reapplied by running Settings → Premium → Restore purchases with the same App Store account.

Deleting the app alone does not cancel it. On Apple, cancel in Settings → Apple Account → Subscriptions; on Google, in Play Store → Payments & subscriptions → Subscriptions. After cancelling, you can keep using it until the end of the period you already paid for.

Payments are processed by the Apple App Store and Google Play, so request the refund there first. Apple: reportaproblem.apple.com; Google: Play Store app → Payments & subscriptions → Budget & history. If the Google Play procedure does not resolve it, email us — the Company can verify the purchase and process it directly. Withdrawal periods, restrictions, and refund deadlines are in Section 9 of the Terms of Service.

First make sure you are signed in with the same App Store account used for the purchase, then run Settings → Premium → Restore purchases. The lifetime license and subscription belong to the App Store where they were purchased and do not transfer between the App Store and Google Play. If that does not help, email us with the App Store receipt number.

The current version does not yet schedule review notifications (it only asks for notification permission in advance); they will be provided in a later version. Notifications are local notifications scheduled on the device, and in versions that provide them, check in device settings that DangoLoop has notification permission and that Do Not Disturb or battery-saver mode is not on. You can also change the notification time and quiet hours in the app’s Settings → Notifications.

Yes. It appears only in regions where the law requires consent, such as the European Economic Area, the United Kingdom, and Switzerland, and you can use every feature of the app even if you decline. You can change your choice at any time in Settings → Ad privacy options. If you purchase a Paid Product, ads stop immediately and the advertising SDK is not started at all from the next launch.

The originals of your study records, exam date, and settings are only on your device, not on the Company’s servers. Deleting the app removes them from the device. What leaves the device (usage statistics, ads, error diagnostics), how to turn it off, and how to request deletion of records held by external companies are explained in the Privacy Policy and the Data Deletion Guide.
