MUJ FISH is designed to be a powerful companion to the student portal, but it operates under a strict set of engineering principles: Zero Third-Party Servers, Zero Portal Interference, and Absolute Privacy.

Here is exactly how the extension operates behind the scenes to ensure your portal experience remains fast, safe, and entirely yours.

1. Direct Communication Architecture

MUJ FISH does not have a backend server or middleman API.

• Direct Fetching: When the extension fetches your grades or attendance, it communicates directly from your browser to the university's servers using your existing, secure login session. There are no proxies involved.

2. Zero Interference with the Portal

The extension is built as a "passive observer." It waits for the portal to completely finish doing its job before it steps in to help.

• Patient Execution: If the portal is experiencing heavy traffic during result days and is taking 2 minutes to load, MUJ FISH will patiently wait. It will never block the portal from loading, intercept the portal's native code, or get in the way of the page rendering.
• Non-Blocking: All calculations (like the CGPA predictor) and background fetches (like checking attendance colors) are run asynchronously. This means you can continue clicking, scrolling, and using the portal normally while the extension works silently in the background without freezing your screen.

3. Server-Friendly & Heavily Optimized

MUJ FISH respects the university's servers. The extension is heavily optimized to use as little bandwidth as possible so it never contributes to portal slowdowns.

• Smart Caching: It utilizes advanced sessionStorage and persistent caching algorithms. If the extension checks for new updated marks in the background, it locks itself down and will refuse to check again during that session to prevent duplicate requests.
• Auto-Aborting Loops: If you rapidly click through the timetable weeks, the extension instantly detects that you are moving fast. It actively kills its own outdated background loops so it doesn't queue up dozens of useless requests to the server. It only processes the specific week you land on.

4. Graceful Failsafes

What happens if the university server crashes or times out?

• Absolutely nothing. If MUJ FISH sends a background request and the university server fails to respond, the extension catches the error silently. It will never crash your browser, throw annoying popups, or break the native portal layout. The portal will continue to function exactly as it normally would without the extension.

---

In short: MUJ FISH is a lightweight layer that sits on top of the portal. If the portal is fast, the extension is fast. If the portal is struggling, the extension waits. You are always in control.

Building Trust & Security

Browser Permissions

• Why are permissions needed? MUJ FISH requests the absolute minimum permissions necessary. It requests access to mujslcm.jaipur.manipal.edu solely so it can inject the CSS (colors) and run the math for your GPA. It requests storage permission strictly to save your toggle preferences and target attendance locally. It cannot access any other websites you visit.

Privacy & Transparency

• For details on local data storage, our strict no-passwords guarantee, and our open-source codebase, please read the Privacy Policy.
