System Requirements Document (SRD)

Project Name: plasma-landing

1. Introduction

The plasma-landing project aims to create a premium landing page for the mobile app WatchDog, a privacy and security application designed to empower users to monitor, protect, and control their device permissions in real-time. This document outlines the system requirements necessary to deliver a high-end, mobile-first, and fully responsive landing page that embodies a clean, minimal SaaS aesthetic comparable to industry leaders like Apple, Notion, and Stripe.

The project will adhere to the design and technical specifications provided by Pranav Kadam, ensuring the final product aligns with his vision for a polished, production-level UI.

2. System Overview

• A hero section with a compelling headline, subtext, and app mockup.
• Feature cards highlighting the app's core functionalities.
• App preview section with screenshots.
• Trust and privacy policy sections to build credibility.
• Help and support section for user assistance.

6. Signature Design Concept

Interactive Privacy Dashboard Hero Section

The homepage will feature an Interactive Privacy Dashboard as the hero section centerpiece. Users will see a clean mockup of the WatchDog app UI, but with a twist: the mockup will be interactive.

• Design Details:

  • The app mockup will display a live simulation of real-time monitoring, permission alerts, and privacy score updates.
  • Hovering over different sections of the mockup will reveal tooltips explaining the features.
  • Subtle floating shadows will give the mockup a premium feel without clutter.

• Animations:

  • Sections fade in as users scroll.
  • Hover interactions scale elements slightly (1.02 max).
  • Buttons change color and shadow intensity on hover for a tactile feel.

This concept ensures the landing page immediately engages users, showcasing the app's functionality in a visually compelling and interactive manner.
