Yes — your quizzes (questions, options, product assignments, and design settings) are preserved when you uninstall PerfectMatch: AI Shopping Quiz. If you reinstall, your existing quizzes will still be there.
A few things to know:
Your live quiz stops working immediately — Once the app is uninstalled, it's no longer connected to your store, so shoppers won't see the quiz until you reinstall and republish.
Your subscription is cancelled — Uninstalling ends the subscription through Shopify. When you reinstall, you'll be asked to approve the subscription again in Shopify before quizzes can run. As always, each billing cycle starts on the Free tier, so approving it doesn't charge you anything by itself.
If you just want to pause your quiz without uninstalling, unpublish it from My Quizzes instead. This hides the quiz from your storefront while keeping the app installed and everything intact.
