Kosudoku — Request Data Deletion

Last updated: July 2, 2026

This page explains how to request deletion of the data associated with your Kosudoku account. Kosudoku does not currently offer in-app account deletion, so requests are handled by email as described below.

How to request deletion

1. Email kosudokucontact@gmail.com with the subject "Delete my Kosudoku data".
2. Include the email address you used to sign in (Google account) and, if you know it, your in-app username, so we can locate your account.
3. We will verify that the request comes from the account owner and confirm by reply.

We aim to complete verified deletion requests within 30 days. Residual copies in encrypted backups are purged within 90 days.

Data that is deleted

On a verified request, we delete the personal data tied to your account, including:

• Profile information — name, email address, profile photo, and username
• Game history, statistics, league/rank standing, and achievements
• Friends list and friend requests
• Chat messages you have sent
• Quickets balance and transaction history
• Device push-notification tokens and analytics identifiers
• Your Firebase authentication account

Data that may be retained

• Purchase records. Payments are processed by Google Play. Limited purchase/transaction records may be retained where required for tax, accounting, or legal compliance, typically for up to 7 years, and are not used to identify you in the app.
• Anonymized/aggregated data. Data that no longer identifies you (for example, aggregate usage statistics) may be retained.
