Itemized privacy policy (Firefox add-on). Effective October 23, 2026.

What Itemized does with your data
When you ask it to, Itemized reads your own Amazon payment history and order pages in your Firefox tab, matches each card charge to the items it paid for, and builds a CSV file that is saved to your computer.

What leaves your browser
Nothing about your orders. Itemized has no server. It does not send your orders, payments, addresses, card details or browsing activity to us or to anyone else, and it contains no analytics or tracking.

Plan check
To know whether you have Pro, Itemized asks ExtensionPay (our payment provider, extensionpay.com) when it is installed and each time you open it. That request carries a random install ID that ExtensionPay creates, and nothing about your orders or your Amazon account. Like any web request it reaches ExtensionPay from your IP address. The install ID is kept in Firefox's extension storage, and syncs between your own Firefox installs if you use Firefox Sync.

Buying Pro
Payment is handled by ExtensionPay and Stripe on their own web pages. They receive what you enter at checkout, such as your email address and card details, and tell the extension whether you have paid. We never see your card number. Their privacy policies apply to that information.

What is stored on your computer
Orders Itemized has already read are kept in Firefox's extension storage so the next export doesn't need to read them again. They never sync anywhere. Use "Forget saved orders" in Itemized, which clears them for every Amazon site, or remove the add-on, to delete them.
