The extension relies on specific DOM selectors to parse the school's grade portal (Genesis). If the school updates their portal's HTML structure, the extension may break (as noted in the changelog with 'patch genesis changes').
The PayPal link in the store metadata is a donation link and does not indicate paid features, but future versions could introduce them.
The extension only works on the specific grade portal page it targets; it does not scrape or store data externally.

付费分析

未识别到付费功能

The extension source code contains no payment logic, no subscription gating, and no premium feature flags. The description explicitly states it is 'free, easy, and open-source'. The only PayPal reference is in the Chrome Web Store support URL (paypal.me/paid529), which appears to be a personal donation link for the developer, not a payment platform integrated into the extension for paid features.

登录理由: The extension is a standalone GPA calculator that runs as a popup and injects a content script into the current tab. There is no login UI, no authentication logic, and no reference to any account system in the source code. The user simply opens the popup and clicks 'CALCULATE' to process the grades visible on the current page.
