Stamped.io

Overview

Stamped.io is a product reviews, ratings, and loyalty rewards platform built for e-commerce brands primarily on Shopify and BigCommerce. The platform enables merchants to collect, display, and syndicate product reviews and photos, run customer Q&A sections, and operate points-and-rewards loyalty programs — all within a unified widget ecosystem embedded directly on the storefront.

Stamped.io competes with Yotpo, Okendo, and LoyaltyLion in the reviews and loyalty space, targeting mid-market Shopify merchants who want social proof infrastructure without enterprise-tier pricing.

What This Script Does

Stamped.io's script (cdn.stamped.io/libs/widget.min.js or similar) embeds reviews and loyalty interfaces on product pages and other storefront locations:

Product review display: The script fetches and renders customer reviews for each product — star ratings, review text, reviewer names, verified purchase badges, and customer-submitted photos. Review content is loaded from Stamped.io's CDN and displayed in a structured widget below product details. Rich snippet markup (JSON-LD schema) is injected to make star ratings eligible for display in Google Shopping and organic search results.

Review submission forms: For post-purchase review collection, Stamped.io sends email review request campaigns to customers (server-side, not via the on-page script). The on-page script renders the review submission form for visitors who arrive via the review request link or initiate a review directly on the product page. The form collects the reviewer's name, email address (for verified purchase confirmation), star rating, title, body text, and optionally photos and videos.

Q&A widgets: Stamped.io embeds a questions-and-answers widget on product pages where visitors can submit questions and view previous Q&A threads. Question submissions collect the visitor's name and email address.

Loyalty program interface: For merchants using Stamped.io's loyalty module, the script renders a loyalty points widget — displaying the logged-in customer's current points balance, available rewards, and earning opportunities. Points redemption interactions are processed through Stamped.io's API and synced with the merchant's Shopify customer records.

Session identifiers and reviewer tracking: The script may use cookies or localStorage to identify returning visitors — for example, to prevent duplicate review submissions or to pre-populate reviewer details for logged-in customers. These are functional identifiers tied to the review and loyalty interactions, not advertising tracking cookies.

Google Shopping syndication: Stamped.io syndicates aggregated review data (overall star rating, review count) to Google Merchant Center for Google Shopping rich snippet eligibility. This is a server-side syndication process, not a client-side data collection activity.

Consent & Compliance

Stamped.io operates in the functional e-commerce category:

• GDPR: Review submissions and loyalty program interactions involve collection of personal data — reviewer names, email addresses, and review content. The lawful basis for processing this data is consent (the reviewer's explicit action of submitting a review) or legitimate interests (maintaining product review functionality that serves the e-commerce customer experience). Merchants should reference Stamped.io as a data processor in their privacy policies and ensure a DPA is in place.
• ePrivacy: Session identifiers used for reviewer identification and loyalty program session management are functional cookies that serve the user's explicitly requested interaction (submitting a review, checking loyalty points). These are generally considered strictly necessary for the requested service.
• CCPA: Review and loyalty data (names, email addresses, purchase history, review content) constitutes personal information under CCPA. Merchants must disclose Stamped.io's data collection in their privacy policy. As a service provider, Stamped.io processes this data on the merchant's behalf.
• Children's data: E-commerce sites that may have minors as customers should ensure Stamped.io's review and loyalty flows do not collect data from children under 13 (COPPA) or under 16 (GDPR Article 8 for digital services).

Should You Block This Without Consent?

No. Stamped.io provides functional e-commerce features — product reviews, star ratings, Q&A, and loyalty programs — that are part of the expected shopping experience and are tied to explicit user interactions. Blocking would remove product social proof and loyalty functionality from the storefront.
