The standard e-Dnevnik interface lacks grade simulation/what-if planning and requires manual login each time. This extension adds auto-login, editable grades for average planning, and an enhanced UI.

User installs extension and opens popup to choose between 'Plus App' (enhanced Vue.js SPA) or 'Plus Classic' (modified original UI) mode. When navigating to ocjene.skole.hr, the extension either redirects to the enhanced app or injects content scripts. If credentials are stored, auto-login fills and submits the login form. Once logged in, users can view grades with enhanced UI, edit grades to simulate scenarios, and see calculated averages. The extension also displays contextual ads from Firebase.

Target users: Croatian primary and secondary school students / Croatian parents of school students

The main Vue.js app bundle (app/js/app.74842662.js, 282KB) is heavily minified and could not be fully decoded; potential features in the Plus App mode may not be fully visible
The extension has 'Plus App' and 'Plus Classic' modes; the Plus App mode redirects to an internal Vue.js SPA whose full functionality is harder to analyze from minified code

Monetization

No paid features detected

No evidence of paid features, subscriptions, payments, or gating in the extension source code. Searches for premium, subscription, payment, stripe, donate, upgrade, in-app returned zero results. All 'pro' keyword hits were false positives (Croatian words 'prosjek'=average, 'proširenje'=extension, 'stopPropagation()'). The extension shows third-party contextual ads via Firebase but does not monetize through paid features. No billing APIs or payment processing code found.

Confidence: 90
Payment platform: --

Login required: Yes
Reason: The extension enhances Croatia's official school gradebook (e-Dnevnik) at ocjene.skole.hr. The content script explicitly targets the /login page, implements autoLogin() that stores and auto-fills username/password into the destination service's login form, and core features (viewing grades, grade planning) require being logged into ocjene.skole.hr. The extension itself has no login UI; it wraps the destination service's authentication.
