Privacy Policy: Buy not, pay never - BNPL blocker
Last updated: October 30, 2026
Summary
Buy not, pay never - BNPL blocker ("the extension") does not collect, transmit, sell or share any personal information or browsing data. Everything it does happens on your own device. It has no servers, no accounts, no analytics and no ads.
What the extension does
The extension blocks buy-now-pay-later (BNPL) offers on websites, such as those from Klarna, Afterpay, Affirm, Sezzle and PayPal Pay Later. It does this in two ways, both on your device:
It uses your browser's built-in request-blocking feature to stop requests to a fixed list of BNPL provider domains.
It looks at the elements on the page you are viewing, by name, attributes and short text such as "pay in 4", and hides the BNPL ones. This check runs locally. The page content is not recorded, copied or sent anywhere.
It then shows how many offers it blocked, on the toolbar badge and in the popup.
Information we collect
None. We do not collect, receive or have access to your name, email address, browsing history, the pages you visit, page content, shopping activity, payment details or any other personal information. The extension does not send any data to the developer or to any third party.
The extension does keep a few things on your device, using your browser's extension storage. They are never uploaded:
Your settings: whether blocking is on, and which providers are blocked.
A running count of how many offers have been blocked.
The optional "assumed cost per offer" number you can type into the popup, used to estimate savings.
Short-lived per-tab counts for the badge. These are cleared when the tab or the browser is closed.
The extension does not record the addresses of the pages you visit or any text from them. Removing the extension deletes everything it stored.
Permissions and why they are needed
The extension asks for the browser permissions below. Each is used only for the purpose shown.
Access to all websites (content script): Finds and hides BNPL widgets on any shopping site. Runs on your device only.
declarativeNetRequest: Blocks requests to a fixed list of BNPL provider domains.
declarativeNetRequestFeedback: Counts how many requests were blocked on the current page, for the badge and popup.
webNavigation: Detects when a new page loads, so the per-page count starts again at zero.
storage: Saves your settings and counters on your device.
The extension does not use remote code. All of its code is included in the package you install.
Third parties, children and changes
Third parties. The extension does not use analytics, advertising, tracking or any other third-party service, and it does not sell, share or transfer any user data. The browser you install it from (for example Google Chrome and the Chrome Web Store) may collect its own information, such as install counts, under its own privacy policy. We have no access to that information.
Children. The extension is not directed at children. Because it collects no data from anyone, it collects none from children.
Changes. If this policy changes, the new version will be posted here with a new "Last updated" date. If a future version of the extension ever needed to collect any data, this policy would be updated and users informed before that version is released.
