Is GeekHelper safe?

GeekHelper adds an opt-in banner on Alza product pages that, when clicked, reloads the page with affiliate parameters.

On Alza.sk and Alza.cz product-detail pages, the extension can show a banner with a button. Clicking it reloads the current product URL with an affiliate ID and banner ID appended. The banner is off by default after install, and the code shows no collection or sending of user data.
