Keepa® adds price history charts directly to Amazon product pages, letting you track prices, analyse trends and make informed purchase decisions across over 7 billion products.\n\n<strong>━━━ ABOUT FIREFOX'S DATA DISCLOSURE ━━━</strong>\n\nIf Firefox showed you a data collection prompt, please read this first - <strong>nothing about how Keepa works has changed.</strong>\n\nSince Firefox 140, every add-on must declare data categories from a fixed list, and Firefox displays that list on install and update. The labels are generic and are <em>not</em> scoped to the sites an add-on can actually reach. What they mean for Keepa:\n<ul><li><strong>Browsing activity</strong> - to draw a price chart, the add-on has to tell <a href=\"https://prod.outgoing.prod.webservices.mozgcp.net/v1/570c780c650408b24713e95de96cea9c720bed6f4b46d86b0f9fa50f2567e0b2/http%3A//keepa.com\" rel=\"nofollow\">keepa.com</a> which product you are looking at, so it sends that product's <abbr title=\"Amazon Standard Identification Number\">ASIN</abbr>. This happens only on Amazon product pages; the add-on does not run on, and cannot see, any other site. The <abbr title=\"Amazon Standard Identification Number\">ASIN</abbr> is used to render the chart. It is <em>not logged or retained</em>, and nothing is stored about you unless you choose to track a product.</li><li><strong>Authentication information</strong> - a token that loads your own Keepa settings and tracked products. It is a credential for your Keepa account. It is <em>not</em> your name, e-mail or address, and <em>not</em> your Firefox or Amazon login - the add-on handles none of those.</li><li><strong>Technical and interaction data (optional)</strong> - your browser type and the add-on version. This one is optional and can be switched off in Firefox's add-on settings.</li></ul>\nNo page content is sent to us. <strong>Keepa does not build a browsing profile and does not sell your data.</strong>\n\n<strong>━━━━━━━━━━━━━━━━━━━━━━━━</strong>\n\n<strong>✓ Price History Charts</strong>\nView interactive price history charts directly on the Amazon product page.\n\n<strong>✓ Price Drop &amp; Availability Alerts</strong>\nSet up price watches to be notified when a product drops below your target price or returns to stock.
