Yes. PerfectMatch: AI Shopping Quiz is installed per store, just like any Shopify app. Simply install the app on each store where you want to run quizzes.
Each store is fully independent:
Quizzes and settings — quizzes, designs, and labels are created and managed separately in each store.
Analytics — each store has its own Analytics dashboard.
Plan and billing — pricing is per store. Each store has its own plan, its own monthly quiz-completion count, and is billed through its own Shopify account.
