Pearl Loop: Masyu Puzzle — Last updated: June 13, 2026

1. Overview

Pearl Loop: Masyu Puzzle ("the App") is a free Android logic puzzle game developed by 강건한건강 ("we", "us"). This Privacy Policy explains how we handle information when you use the App.

2. Information We Collect

The App does not collect, store, or transmit any personal information to our servers. It is a 100% offline puzzle game with no user accounts and no server-side communication.

3. How Puzzles Are Generated

Every Masyu puzzle is generated on your device and is guaranteed to have a single solution reachable by logic alone — no guessing required. No internet connection is needed to play, and nothing about you is sent anywhere to create or check a puzzle.

4. Third-Party Services

The App uses the following third-party service:

• Google AdMob — for displaying advertisements. The App shows a banner at the bottom of the screen, a full-screen ad after a puzzle is completed, and an app-open ad on launch. There are no ads while you are solving a puzzle. AdMob may collect device identifiers (such as Advertising ID) and usage data to serve personalized or non-personalized ads. For more information, see the Google Privacy Policy.

5. Permissions

The App requests only internet access, which is used to load ads. The App does not use or request access to your location, microphone, contacts, camera, or files.

6. Data Storage

The App does not create user accounts and does not sync any data to the cloud. Uninstalling the App removes any cached AdMob data stored on the device.

7. Children's Privacy

The App is suitable for general audiences and is not directed at children under the age of 13. We do not knowingly collect personal information from children.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
