Is Shopilo: Automatic Coupon Finder by DontPayFull Safe? — Extension Safety Profile

This extension requests a broad set of permissions that allow it to read and interact with all websites you visit. The host permission combined with scripting, webRequest, and cookies access means it can see page content, monitor network requests, and read or modify cookies on any site. For a coupon finder, scanning pages for discount codes is expected, but the ability to access sensitive data like banking or email cookies across all domains is a significant capability that goes beyond simple coupon matching.

Users of coupon and deal-finding tools should be aware that these extensions often earn revenue by modifying affiliate links or injecting their own tracking codes when you make a purchase. This is a common and legal practice in the category, but it means the extension can influence which retailer gets credit for a sale. A careful user should also consider that any tool with such wide-ranging web access could potentially be a target for supply-chain attacks or become a vector for data collection if the developer's practices change.

The fact sheet shows a strong Maintenance & Ownership score, indicating the extension is actively updated, and a high Community Reputation score based on its store rating. However, the weakest dimension is Permissions & Access, reflecting the extensive host and API permissions requested. The developer's privacy disclosures state they collect personally identifiable information, web history, and user activity, which aligns with the permissions granted but is something a privacy-conscious user should review carefully before installing.
