Data Deletion
Effective date: June 19, 2026 · Last updated: June 20, 2026
Overview
YFi-studio games (Num Puzz and Sha Puzz) by YAlpha Co., Ltd. do not require an account or login. Most of your game data — such as progress, stars, hearts, and settings — is stored locally on your device and is never tied to a personal account. This page explains how to delete data stored on your device, as well as how to request deletion of any data processed by our service providers.
1. Delete Data Stored on Your Device
You can remove your locally stored game data at any time:
- In-game reset — if the game offers a "Reset progress" option in its settings, use it to clear your local progress.
- Uninstall the app — deleting the game from your device removes its locally stored data, including progress, hearts, and settings.
2. Request Deletion of Server-Side Data
Some data may be processed by our service providers for analytics, advertising, crash reporting, and purchases (for example, Google Firebase, Google AdMob, RevenueCat, and the app stores). To request deletion of this data, send us an email and we will process your request:
- Send an email to support@yalpha.company with the subject line "Data Deletion Request".
- Tell us which game you played (Num Puzz or Sha Puzz) and your platform (iOS or Android).
- If you have it, include your advertising identifier or any purchase receipt/order ID, which helps us locate the relevant records.
3. What Gets Deleted
Upon a valid request, we will delete or anonymize the personal data we are able to associate with you that is held for analytics, advertising, and crash reporting purposes. Some records may be retained where required for legal, security, tax, or accounting reasons (for example, purchase and payment records held by the app stores), as described in our Privacy Policy.
4. Response Time
We aim to acknowledge requests within a reasonable period and to complete verified deletion requests in line with applicable law. We may need to verify your request before acting on it to protect against unauthorized deletion.
