Xianxiu: Guardian of the Sect (仙修守山) · Last updated: November 9, 2026
These Terms of Service ("Terms") govern your use of Xianxiu: Guardian of the Sect (仙修守山, the "Game"), published by Butterfly AI LLC ("we", "us"). The Android package name is com.butterfly.xxiu. By downloading or playing the Game, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Game.
Xianxiu is a single-player xianxia tower defense game. You place disciples from four sects along a stone path, spend spirit stones, and keep demons from reaching the sect gate. The Game has four maps, waves of foes, a Demon King at the end of each map, and breakthroughs that raise a disciple's strength. Progress, including unlocked maps, stars, language, display settings, and music and sound volume, is saved on your device. There is no account.
The Game is free. It does not sell in-app purchases or subscriptions. Spirit stones, stars, unlocked maps, and other items inside the Game are virtual, have no cash value, and cannot be transferred or redeemed for money.
Features may change, pause, or stop as we operate the Game.
You must be at least 13 years old, or the minimum age required where you live if that age is higher. If you are under the age of majority where you live, you may play only with a parent or guardian's permission. The Game is not directed at children under 13.
We give you a personal, non-exclusive, non-transferable, revocable license to install and play the Game on devices you own or control, for your own entertainment. You do not own the Game. You may not copy it, sell it, rent it, or give someone else a copy, except as the store or the law allows.
You agree not to:
The Game is free and supported by advertising. After you clear a map, a full-screen ad from Google AdMob may appear when you continue, retry, or return to the map list. An ad is not shown when you lose. If an ad is not ready, play continues without one. Showing an ad needs a network connection. The rest of the Game can be played offline. Ad availability is not guaranteed. Google's terms apply to the ad. We do not control the content of a third-party ad. Where required, Google may ask for your consent before ads are shown. See the Privacy Policy for how advertising data is handled.
The Game, including its software, name, icon, sect and map art, text, and audio, belongs to us or our licensors and is protected by intellectual-property laws. These Terms do not transfer any of that ownership to you.
If you download the Game from Google Play, Google Play's terms also apply to the download. We are not responsible for a store, a network, a device, or an advertising service we do not control. Uninstalling the Game deletes the local save on that device. We cannot restore a save, because we do not keep a copy of it.
THE GAME IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE GAME WILL BE UNINTERRUPTED, ERROR-FREE, OR AVAILABLE ON EVERY DEVICE.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE AND OUR AFFILIATES AND SUPPLIERS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, PROFITS, OR GOODWILL, ARISING FROM YOUR USE OF THE GAME. OUR TOTAL LIABILITY FOR A CLAIM RELATING TO THE GAME WILL NOT EXCEED USD $50. SOME PLACES DO NOT ALLOW THESE LIMITS. WHERE THEY DO NOT, OUR LIABILITY IS LIMITED TO THE EXTENT THE LAW ALLOWS. NOTHING IN THESE TERMS LIMITS LIABILITY THAT CANNOT BE LIMITED BY LAW.
You may stop playing and uninstall the Game at any time. We may suspend or end the Game, or stop offering it in a store, if you break these Terms, if the law requires it, or if we discontinue the Game. Sections that should survive, including ownership, disclaimers, and liability limits, survive.
We may update these Terms. The "Last updated" date on this page will change. If you keep playing after the update is posted, you accept the new Terms.
These Terms are governed by the laws of the operator's principal place of business, without regard to conflict-of-law rules, except where consumer protections where you live must apply.
