Extension Details
Context-Aware Verdict
The extension has a very limited user base with only 6 ratings and a modest 3.3-star rating, which provides minimal confidence in its reliability. The developer appears to be associated with hiragana.training website, suggesting some legitimacy for a Japanese language learning tool. However, the lack of detailed developer information and extremely small user base raises questions about ongoing support and maintenance.
The unlimitedStorage permission seems excessive for a simple hiragana training application, as basic flashcard or quiz functionality should not require unlimited local storage capacity. The notifications permission, while potentially useful for study reminders, adds unnecessary complexity for what should be a straightforward learning tool. The extension uses the older Manifest V2, which has weaker security protections compared to the current V3 standard. The combination of broad storage permissions with minimal user adoption creates potential for misuse without sufficient community oversight.
Consider running this extension in a separate Chrome profile to isolate any potential risks from your main browsing environment. Look for alternative hiragana learning extensions with larger user bases, better ratings, and Manifest V3 compliance. If you choose to use this extension, monitor your browser's storage usage and be cautious about any unexpected notifications. Given the specialized nature of the tool, evaluate whether web-based alternatives might serve your learning needs more safely.
