How to check your receipts in Android
As purchases in Android are done in the Play Store, the Mojo team cannot issue invoices directly. You can retrieve your receipts directly from your Google account. To access your recent receipts go to: pay.google.com and sign in with your Google account. Then click Subscriptions & services, find the subscription or service you want and click Manage. You can find more information about how to manage your subscriptions in Google Play help center.
