付费分析

未识别到付费功能

Extension is explicitly open source. No premium tier, subscription, purchase, or payment UI detected. The 'pro' keyword matches are all false positives from localization files where 'pro' appears in words like 'protocol', 'progress', 'protection', 'prompt'. No payment platforms (Stripe, PayPal, etc.) or billing APIs found. All features appear freely accessible without any gating.

登录理由: No login UI, authentication flow, or user account system found. The 'session' keyword matches are all from chrome.storage.session API (Chrome's built-in session storage, not user authentication). The 'auth' keyword matches are HTTP Authorization header capturing (for media sniffing) and a legal disclaimer about 'authorized access' to content. The 'token' keyword is for aria2 RPC integration with a local download manager. No OAuth, sign-in, or account registration flows exist.
