support@emtilabs.com · Your email app opens; you send the message yourself.

Before contacting support

  1. 01

    Protect your existing account

    Check your sign-in method and player ID before uninstalling. To link a new method, first sign in to your existing Hollow Playground account.

  2. 02

    Describe what happened

    Include the app version, device model and steps leading to the problem. Hide personal details in screenshots. You can include your player ID if you know it.

  3. 03

    Keep secrets private

    Do not send passwords, sign-in codes, recovery keys, session tokens or payment-card details. Knowing a player ID alone does not prove account ownership.

Accounts and testing

Are Google sign-in and Play Games the same?

They are separate sign-in methods. To keep using existing progress, sign in with your original method, then link the new method offered in Account management to that account. Matching email addresses do not automatically merge accounts.

Why is Facebook or Play Games sign-in unavailable?

The new sign-in methods are being validated in Android internal testing. Test access, app version and device support for the service matter. Send the error message to support rather than repeatedly creating new accounts.

How do I join internal testing?

Testing is currently by invitation. If invited, use the official Google Play test link you received and an authorized Google account. This site does not offer a public download or automatic test registration.

How do I delete my game account?

Use Account and data deletion on the privacy page or email support@emtilabs.com. You can apply even without the game installed. After secure ownership verification, the relevant services are handled separately.

Where do I get purchase or refund help?

For versions offering purchases, use Google Play’s official help channel or contact us. Include the order number and issue description, not payment-card details. General sales are not open in the current internal test.

Account and data deletion

The privacy page explains requests, ownership verification, the data removed and retention periods. Uninstalling does not delete your account.
