We collect nothing. The Amazon Keyword Rank Tracker extension does not collect, transmit, or store any personal data. Keywords, ASINs, and rank results you enter or generate are processed entirely on your device and kept in local browser storage only, for the sole purpose of resuming an in-progress query after the browser suspends the background worker.
The extension has no server, no remote code, and loads no external scripts or analytics.
What it accesses: When you click "Start", it opens Amazon search result pages in background tabs and reads the visible product information (ASIN, title, price, link, ad placement) from those pages to compute ranks — always initiated by you, only for the keywords you specify. It also reads the URL of your active tab to detect which Amazon marketplace you are on.
No data leaves your device. Queries run in your own browser session using your own login and cookies; the extension never touches your account credentials. Nothing is shared or sold. Removing the extension from chrome://extensions deletes all local state.
Pro license activation: For ARTK- keys (domestic channel) validation happens entirely on-device with no network request. For Lemon Squeezy keys (international channel), the activation call sends the license key plus a random instance identifier to api.lemonsqueezy.com — the standard flow of the payment platform. Keywords, ASINs and rank data are never transmitted.
