A reviews block for the product page, and nothing else. Shoppers write a review under the buy button: a rating, a name, a few words. Every review waits for you before it appears, unless you switch that off. Once there are reviews, the page shows the average, the count and a bar per star, and carries the structured data Google reads, so the rating can show in search. No API scopes, no email requests, no customer records: a reviewer’s name is the only personal data, and it goes with the review.
