Delete your World Master account & data

App: World Master (com.worldmaster.world_master)
Developer: Enea Xhengo
Support: worldmaster.support@gmail.com (public email)

Fastest: delete inside the app

Open World Master → Profile → Account, then choose:

Delete cloud backup — removes your cloud learning backup for this account. Your progress on the device is kept and your account stays active.

Delete account and all data — permanently deletes your account and all its data (see below). You confirm, then re-enter your password.

The on-device flow also removes this account's learning and personal data (including your passport photo) from the device.

Request deletion without the app

If you cannot use the app, email your request to worldmaster.support@gmail.com (plain text: worldmaster.support@gmail.com) with the subject "Delete my World Master account".

Send the email from the address on your account so we can verify you own it. We must confirm ownership before deleting anything.
Include only: your account email address, and a clear statement that you want your World Master account deleted.
Do NOT include your password or any payment-card information.
Confirmation — we will confirm when your request is completed.

Never send a password or payment-card details by email. We will never ask for them, and they are not needed to delete your account.

What is deleted

Your Firebase account (email/password sign-in).
Your cloud learning backup: memory/progress, passport stamps, streak, activity, Deep Explorer reading.
On your device (when the app next runs): this account's learning + personal data, including your passport photo, profile name and passport personalization.

What may remain

Your Google Play subscription is not cancelled by account deletion — manage or cancel it in Google Play. Account deletion does not affect payment obligations.
Any records we are legally required to retain: RELEASE_INPUT_REQUIRED (legal review).
Standard Google/Firebase operational logs and Google's own technical backups are governed by Google's retention; we do not operate a separate backup-retention schedule.

Processing time

Deletion initiated inside the app begins immediately after final confirmation (server-verified). Requests submitted by email are completed within 30 calendar days after account ownership has been verified.
