Account & Data Deletion

Method 1: delete the account in the app

Open NumiPop and sign in.
Select Account → Delete account and data.
Review the data to be deleted and enter the current password.
Select Permanently delete account.

The app reauthenticates the user, deletes the Cloud Firestore account document, all learner profiles, and quiz results, and then deletes the Firebase Authentication account. It displays the completion dialog only after every step succeeds.

Method 2: request deletion by email

If you uninstalled the app or cannot sign in, send a request from the email address registered to the account.

Send an account deletion request

Deletion request email: [email protected]

Use the subject [Account deletion request] NumiPop and include the registered email address and the statement “Delete my account and all associated data.”

Do not email your password, one-time code, national identification number, a full image of an identity document, or anyone else's personal data. If further verification is necessary, we will request only the minimum information reasonably needed.

Data deleted

Firebase Authentication email account and Firebase UID
Cloud Firestore account document, email, language, and aggregate learning statistics
All learner nicknames and profiles
Quiz and question records, scores, correct answers, streaks, and learning timestamps
Account-linked profile selection, quiz preferences, and pending upload records on the device

Guest data on the device

Guest learning records that are not linked to the account stay only on the device and are not part of account deletion. The current deletion dialog has no separate option to delete every guest record. You can remove local guest data by clearing NumiPop's app data in Android settings or by uninstalling the app.

Uninstalling is not account deletion

Uninstalling the app from your device does not delete your Firebase account or learning records stored on our servers. To delete your account and server-stored data, use the account deletion feature in the app or submit a request using the email method described on this page.

Timing and recovery

When an account is deleted directly in the app, the deletion process for the account and associated data begins after password verification. Deleted accounts and learning data cannot be restored. However, it may take up to 180 days for Firebase Authentication data to be completely removed from Google's live and backup systems.

Email requests are normally handled within seven days and may take up to 30 days where technical review or legally required retention is involved. We send the outcome to the address used for the request.

External product purchases and payment data

The NumiPop app has no in-app billing or subscription feature or payment SDK and stores no payment information or payment records in the Firebase account or Cloud Firestore. The Korean account menu can open a Naver Smart Store product page for image arithmetic cards. Order and payment records held by that external store are managed separately under its policies and legal retention requirements and are not deleted by this Firebase account deletion process.
