Hi! I understand you're worried about losing access to your HQ if you delete and reinstall Puzzles & Survival. Let me clarify that for you.

Deleting and reinstalling the app itself does not make you lose your HQ or game progress, as long as your game account is linked properly—usually through your game account, Facebook, Google, or Apple ID. When you reinstall, just be sure to log back in using the same method you used before. That will restore your HQ and all progress.

Before reinstalling, if you can still open the app even briefly, I recommend checking under the game’s More > Account > User Center to ensure your game account is linked and note the login method (like Apple ID or Facebook). If you get stuck on the login screen after reinstalling, you can use the "Switch Account" feature in the same menu to switch back to your saved account.

If you want, I can guide you step-by-step through this reinstallation and login process on your iPhone 18.6 iOS to make sure your HQ is safe. Would you like me to do that?
