Privacy Policy

Last updated: April 2025

Overview

SellerBeam is designed with a local-first architecture: all data processing happens on your own machine. Your Amazon Selling Partner API credentials are stored in a local .env file and are never transmitted to any third-party server operated by SellerBeam.

This privacy policy describes how SellerBeam (the Chrome extension and the companion local server software) handles information, and how this website (sellerbeam.com) operates.

Data collected by the Chrome Extension and Local Server

No data is collected or transmitted to SellerBeam.

The SellerBeam Chrome extension communicates exclusively with the companion server running on your local machine (localhost:3001). The local server makes requests to Amazon's Selling Partner API using your own credentials and returns the data directly to the extension.

No product data, ASIN data, seller data, pricing data, or credentials are:

  • Sent to any SellerBeam server or third-party server
  • Stored in any remote database
  • Used for analytics or advertising
  • Shared with any third party

Amazon SP-API credentials

Your Amazon SP-API credentials (Client ID, Client Secret, Refresh Token, Seller ID) are stored exclusively in a local .env file on your machine. These credentials are used solely to authenticate requests to Amazon's Selling Partner API on your behalf.

SellerBeam never reads, stores, or transmits your credentials beyond the communication between the local server and Amazon's official API endpoints.

Amazon SP-API data usage

Data retrieved from Amazon's Selling Partner API (including product information, fee estimates, eligibility status, pricing data, and offers) is:

  • Fetched in real time when you open an Amazon product page
  • Displayed in the SellerBeam sidebar in your browser
  • Not stored beyond the active browser session
  • Not transmitted to any server other than Amazon's own SP-API endpoints

Your use of SP-API data is also governed by Amazon's Data Protection Policy. By using SellerBeam, you agree to comply with Amazon's terms for SP-API usage.

This website (sellerbeam.com)

This website is a static informational site. It does not require login and does not collect personal information from visitors.

If you contact us via email, we will use the information you provide only to respond to your inquiry. We do not add you to any mailing list without your explicit consent.

Third-party services

SellerBeam integrates with or links to the following third-party services:

  • Amazon Selling Partner API — used to retrieve product data. Subject to Amazon's data protection policies.
  • Keepa — the sidebar contains a link that opens Keepa's price history chart for a given ASIN in a new tab. SellerBeam does not transmit any data to Keepa; you are navigating to Keepa's website directly. Keepa has its own privacy policy.
  • Google Chrome Web Store — the extension is distributed via the Chrome Web Store. Google's own privacy practices apply.

Data retention and deletion

Because SellerBeam does not collect or store your data on any remote server, there is no data to delete. Uninstalling the Chrome extension and deleting the local server directory removes all SellerBeam software from your machine.

Children's privacy

SellerBeam is intended for use by Amazon sellers and is not directed at children under the age of 13. We do not knowingly collect information from children.

Changes to this policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated date. Continued use of SellerBeam after changes are posted constitutes acceptance of the revised policy.
