For support, feedback, correction requests, or store purchase issues, contact learnenglishwithmusicsg@gmail.com.
Please include your device model, operating system version, app version, the book and level you were reading, and a short description of the issue.
The books and dictionary are bundled offline. If ads or purchases do not appear, check the internet connection and make sure you are using the same App Store or Google Play account used for purchase.
The one-time Unlock All Books purchase gives access to the full library at every A1–B1 level and removes ads. To restore this purchase on iOS, use Restore Purchase in the app while signed in to the same Apple Account used for the purchase.
Rewarded-ad credits and books unlocked with them are stored locally on this device. They are not synced to your Apple Account and are not recovered through Restore Purchase. These book unlocks do not remove ads.
Deleting the app's data or reinstalling the app may remove your credits and rewarded book access. Recovery from a device backup is not guaranteed.
