Platforms & saving
How to play and protect your progress.
Android & browser
The Android version has a Google Play listing; availability for your account depends on the app’s distribution stage. The web version is enabled for iPhone, iPad, and Mac. Other devices see the Android link on the game page.
This wiki is open on every device. On iPhone, open the game in Safari, tap Enter the shelter, and use landscape orientation. Share → Add to Home Screen creates an icon. A paid Apple developer account is not required.
Local and cloud saves
Your shelter is saved locally. In Settings → Account & cloud backup, create an optional account to restore progress on another device. Synchronization retries every 30 seconds when connected. If the copies differ, choose which to keep; neither is replaced automatically.
Keep your recovery key outside the game. Do not clear site data before confirming your shelter was synchronized. Saves do not transfer purchase entitlements between stores.
Offline play on iPhone
The first launch requires internet. After a complete load, the browser caches game files for later offline launches. In Safari, use Share → Add to Home Screen. If the browser clears its cache, or you use private browsing, another download is required.
Offline play does not require signing in. Progress stays local and synchronizes when the connection returns if you are signed in.
