Seller Central Quick-Switch ("the extension") is a free Chrome extension developed by Welch Commerce Systems. This privacy policy explains what data the extension accesses, what it stores, and what it does not do.
The extension does not read page data from Seller Central or the Advertising Console. It only listens for the keyboard shortcut configured by the user (Ctrl+K by default, Cmd+K on Mac). When the shortcut is pressed, the extension renders its own command palette overlay; the palette's contents are the user's own page list, not anything scraped from the page.
The extension only attaches its keyboard listener on Seller Central domains (sellercentral.amazon.com and its regional variants) and on advertising.amazon.com. It does not run on any other site.
The extension stores the following items locally using Chrome's
chrome.storage.sync API:
These items are stored under the user's Chrome profile and may sync to the same browser profile on the user's other devices via Chrome's built-in sync, if the user has Chrome sync enabled. Nothing is stored off-device by the extension itself.
The extension does not collect, transmit, store off-device (beyond Chrome's own sync of preferences), sell, share, or otherwise process any of the following:
The extension does not phone home, does not contact any external server, and does not use any analytics services.
The extension does not share any data with third parties because the extension does not collect any data to share. The extension does not include analytics SDKs, advertising networks, or any other third-party code.
The extension requests the following Chrome permissions:
storage: used only to save the user's page list, custom keyboard shortcut, and recently used page list via chrome.storage.synchost_permissions for sellercentral.amazon.com (and the supported regional Seller Central domains) and advertising.amazon.com: required so the keyboard shortcut listener can attach on those pagesThe extension's complete source code is included in the installation package. Users are encouraged to inspect the code to verify the claims in this privacy policy.
