Users who shop directly on partner brand websites miss cashback opportunities because they forget to go through the Rakuten Rebates portal first. This extension solves that by detecting partner stores and proactively notifying users about available cashback.

1. User installs the extension and logs in with their Rakuten ID on rebates.jp. 2. When the user visits a partner brand store website, the content script detects the store via URL matching. 3. A popup/notification appears showing the available Rakuten Point cashback rate (e.g., '楽天ポイントX%還元'). 4. User clicks 'activate' to enable cashback tracking for that shopping session. 5. The extension tracks the purchase and reports it to the Rakuten Rebates API. 6. Cashback points appear in the user's account summary shown in the extension popup.

Target users: Japanese online shoppers who use Rakuten Rebates (楽天リーベイツ) for cashback / Users who want to earn Rakuten Points when shopping at partner brand stores

All JavaScript bundles are minified/webpack-bundled making deep code flow analysis difficult
Some keyword matches (subscribe, checkout, purchase) were false positives from bundled libraries and commerce detection patterns
The exact behavior when user is not logged in (e.g., whether notification still shows without activation capability) could not be fully confirmed from source alone

Monetization

No paid features detected

The deterministic heuristic's positive keyword hits (subscribe, subscriber, checkout, purchase) are false positives. 'checkout' and 'purchase' appear in the content script's order confirmation page detection patterns used to track successful cashback transactions, not paid feature gating. 'subscribe'/'subscriber' appear in bundled library code. No subscription tiers, premium plans, Stripe/billing integrations, upgrade UI, or payment gates were found in the extension source. The accountSummary amounts (paidAmount, payableAmount, pendingAmount, totalAmount) represent cashback earnings from shopping, not payments for the extension. The extension is free; it earns revenue as a cashback affiliate platform (users shop through partner links and earn Rakuten Points).

Confidence: 82
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension integrates with the Rakuten Rebates (rebates.jp) member system. The popup has an isLoggedIn computed property checking member.id (popup/js/components/popup-content.vue:69-70). The locale JSON in content/bundle.js includes login_button: '楽天IDでログイン' (Login with Rakuten ID). URL templates include LOGON_FORM: 'https://%domain%/login' and LOGIN: 'https://%domain%/rakuten/login'. API endpoints USER_STATUS and MEMBER_DETAILS confirm server-side session checks. While the notification popup may display without login, activating cashback (the core workflow) and viewing account summary (paidAmount, payableAmount, pendingAmount) require being logged into the rebates.jp service.
