Review Check – Privacy Policy

Last updated: October 2026

Review Check is a browser extension that estimates whether the reviews on an Amazon product page look genuine. This page explains which data it uses and what happens to it.

What is sent, and when

Only when you open an Amazon product or review page and a check runs (automatically or by clicking “Check reviews”), the extension sends to the Review Check server:

• the texts, titles and star ratings of the reviews shown on that page,
• the product title and the product number (ASIN),
• a random installation ID, created by the extension, used only to count the free checks per day.

No names of reviewers, no account data, no browsing history, no cookies and nothing from other websites are sent. The extension does not track you and contains no analytics or advertising.

How it is processed

• The server asks the AI model Jev by TypeSafe AI about the reviews. TypeSafe processes the texts to answer and does not keep them (zero data retention).
• The answers are kept in the server's memory for up to 24 hours, so the same reviews are not paid for twice. They are never written to disk and are lost on every restart.
• The server stores only an anonymous daily count of checks per installation ID, with a one-way hash instead of the product number. These counts are deleted after 7 days.

In your browser

Results stay in your browser's extension storage for one week, so a product you checked shows its result again. Uninstalling the extension deletes them.

Sharing

Data is not sold or shared with anyone. Besides TypeSafe AI (the AI model) and Railway (where the server runs), no third party receives it.
