Player support
How can we help?
Bus Express players can contact us after launch, while LUMIBIND testers can reach us during closed testing. Review the checklist below and include the game version and device details in your message.
General questions
Installation problems
Install Bus Express from its public Google Play listing. For LUMIBIND, open the test link with the invited Google account. If installation still fails, restart the store and check your Android version and free storage.
Purchases and restoring purchases
Google Play manages payments. If a purchase is not restored, include the game name and Google Play order reference — never the full receipt or payment details.
Advertisements
Advertising and purchase details are explained in each game's privacy policy. Bus Express and LUMIBIND use their own documented settings.
Lost progress
Save and recovery options differ by game. Tell us which title and device are affected so we can give the correct guidance.
Errors and crashes
When contacting support, include the game name, device model, operating-system version and a clear description of what happened.
Privacy and data deletion
Bus Express and LUMIBIND already have dedicated privacy policies with the applicable data and deletion instructions.
