If you remember making a purchase in this app, but don’t remember the Apple ID you used or its password, please try the following:
- Lookup emails from Apple with a subject line of “Your Invoice From Apple”.
This email is being sent for every purchase you make, and it contains both the Apple ID and the purchased app (or in-app).
This may provide a lead to find your Apple ID that was used to make an in-app purchase in this app.
- Visit the link below to Apple’s support page in this matter and follow their suggested steps to recover a lost Apple ID or password.
