Website

SuppStacker uses privacy-friendly analytics to understand aggregate traffic patterns. We do not sell or share personal data with third parties.

Chrome Extension

The SuppStacker Chrome extension helps you see what health experts say about supplements while browsing Amazon product pages. Here is exactly what it does with your data:

What the extension reads

On Amazon product pages, the extension reads publicly visible product information (title, brand, and product identifier) to determine whether the product is a supplement. This information is processed entirely on your device and is not transmitted to any server.

Network requests

To identify supplements, the extension downloads a catalog of known supplement names from the SuppStacker API. This request is made once and cached locally for 24 hours. It does not include any information about you or the pages you visit.

When you click the expert reviews badge to open the review panel, the extension sends supplement identifiers and names to the SuppStacker API to retrieve expert review data. No product identifiers (such as ASINs), personal information, or Amazon account data are included in these requests.

The review panel also loads first-party expert avatar images from SuppStacker-owned web infrastructure so the interface can render expert photos consistently.

Local storage

The extension stores a cached copy of the supplement catalog on your device, refreshed daily, along with the current product context. This data stays on your device and is not transmitted.

Third parties

Network requests go only to SuppStacker-owned services used to power the extension, such as the SuppStacker API and first-party image assets. No data is shared with advertisers, analytics providers, or unrelated third parties by the extension.
