In-depth safety analysis
The extension requests broad host permissions (http://*/*, https://*/*) along with tabs, storage, and sidePanel. This allows it to read and modify data on any website you visit, see your open tabs, and store settings. For a fantasy sports tool, such extensive access is broader than strictly necessary—it could potentially monitor all browsing activity, not just fantasy platforms. Users should be aware that granting this level of access means the extension can see sensitive information like banking or email pages if it is active.
General browser extensions with all-site access carry inherent risks. Even well-intentioned tools can be hijacked or cloned to inject ads, track browsing, or steal credentials. Fantasy sports extensions are popular targets for phishing clones that mimic legitimate tools. The fact that this extension is currently unavailable on the Chrome Web Store is a notable red flag; it may have been removed for policy reasons or by the developer, which warrants caution before installing from other sources.
The safety score is strong overall (80.89/100, Grade A), but the dimensions reveal a contrast. The weakest area is Publisher & Identity (60%), suggesting limited transparency about the developer’s background. The strongest is Maintenance & Ownership (100%), indicating the extension is actively maintained and ownership is clear. While the privacy practices declared by the developer are positive, the combination of broad permissions and current store unavailability means users should carefully consider the trustworthiness of the source before installing.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.
