Sparebørsen Chrome extension: automatic cashback

Do you sometimes forget to check Sparebørsen before you shop? Most people do. That is why we have built a Chrome extension that makes cashback entirely automatic. Here we explain how it works and why you should install it today.

What does the extension do?

The Sparebørsen extension for Chrome runs quietly in the background while you browse. When you visit an online shop that is a Sparebørsen partner, a small reminder appears telling you that cashback is available. One click activates the cashback, without having to go via our site first.

How to install it

• Go to the Chrome Web Store and search for «Sparebørsen».
• Click «Add to Chrome» and confirm the installation.
• Sign in with your Sparebørsen account and you are done.

The extension is completely free and needs minimal permissions. It reads only the web address you are visiting, to check whether the shop is a partner.

Features

Beyond automatic reminders, the extension has several useful features:

• Cashback overview: See your total cashback balance directly in the browser.
• Compare rates: The extension shows the current cashback rate for the shop you are visiting.
• Activate with one click: No detours; activate cashback straight from the popup window.
• Search partners: Quickly find out whether a shop offers cashback without leaving the page you are on.

Privacy

We take privacy seriously. The extension sends only the shop's domain name to our servers, to check whether it is a partner. We store no browsing history, and the extension has no access to sensitive data such as passwords or payment details.

How much can you save?

Users who install the Chrome extension earn on average 40% more cashback than those who use the website alone. The reason is simple: the extension reminds you to activate cashback on every relevant purchase, so you never miss out on a saving. Over a year that can amount to several thousand kroner extra.

Does it work with other browsers?

For now the extension is available for Google Chrome and Chromium based browsers such as Microsoft Edge and Brave. We are working on support for Firefox and Safari during 2026.
