Xianxiu: Guardian of the Sect (仙修守山) · Last updated: October 25, 2026

This Privacy Policy explains how Butterfly AI LLC ("we", "us") handles information when you play Xianxiu: Guardian of the Sect (仙修守山, the "Game"), a xianxia tower defense game for Android. We do not ask you to create an account, and we do not collect your name, email address, phone number, contacts, photos, or precise location.

1. Information stored on your device

The Game saves progress only on your device. That save can include unlocked maps, stars, language, display resolution, and music and sound volume. We cannot see this save. It is deleted when you uninstall the Game.

2. Information collected by third-party services

The Game uses Google AdMob, which may collect information automatically from your device:

ServicePurposeInformation it may collect
Google AdMob (including Google's User Messaging Platform) Showing a full-screen ad after you clear a map, when you continue, and asking for consent where required Advertising identifier (Android Advertising ID), IP address, device model, operating system, language, approximate location derived from IP, and ad interactions

Google processes this information under its own privacy policies:

The Game does not offer in-app purchases and does not use a game account, analytics SDK, or social login.

3. Consent and your choices

4. How we use information

We use the information described above only to run the Game, show ads that support the free version, and keep the Game working. We do not sell your personal information.

5. Data retention

Data on your device is kept until you uninstall the Game. Data collected by Google is kept according to Google's retention policies.

6. Children

The Game is not directed at children under 13 (or the minimum age in your country), and we do not knowingly collect personal information from them. If you believe a child has provided personal information through the Game, contact us and we will help remove it.

7. Your rights

Depending on where you live (for example under the GDPR or the CCPA/CPRA), you may have the right to access, correct, delete, or object to the processing of your personal information. Because we do not hold an account for you, most requests are best handled in your device settings or directly with Google. You can also contact us and we will help.

8. Security

We rely on the security measures of Google Play, Google AdMob, and the operating system of your device. No method of transmission or storage is completely secure.

9. Changes to this policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with a new "Last updated" date.
