Privacy Policy

Last updated: 2026-07-18

1. Introduction

hiimobapps ("we", "us") operates the mobile game Pile Blocks / 垒方块 (the "App") on iOS and Android. This policy explains what information the App collects and how it is used. It differs by platform, as noted below.

2. Information we collect

iOS: The iOS version shows advertisements through Yandex Mobile Ads, which may collect an advertising identifier, device information, IP address and approximate (IP-based) location for ad delivery and measurement. The iOS version uses no analytics or crash-reporting SDKs and has no leaderboard.

Android: The Android version uses Google AdMob (advertising), Firebase Analytics (usage analytics), Firebase Crashlytics (crash diagnostics) and Google Play Games (leaderboard). These may collect an advertising identifier, device and usage data, diagnostic/crash data, and — if you sign in for the leaderboard — your Google Play Games player ID.

Both platforms: Game data such as your high score is stored locally on your device and is not uploaded to us.

3. Third-party services

4. How we use data

To deliver and measure advertising, understand aggregate usage, diagnose and fix crashes, and provide the leaderboard. Advertising is configured as non-personalized.

5. Children's privacy

The App is suitable for all ages. We do not knowingly collect personal information from children for profiling, and advertising is served as non-personalized. The App is not listed in the App Store "Kids" category. Parents or guardians may contact us to request deletion of any data.

6. Data retention & security

We retain data only as long as necessary for the purposes above. Third-party providers process data under their own privacy policies linked in section 3.

7. Your choices & rights

You can reset or limit your advertising identifier in your device settings. You may request access to or deletion of your data by emailing us.

8. Changes to this policy

We may update this policy; the "last updated" date above reflects the latest revision.
