## What is PolyWeb?

PolyWeb is a lightweight, privacy-isolated mobile browser engineered for web developers, designers, and privacy-conscious users who require flexible web previewing, responsive layout testing, and isolated browsing sessions.

Whether you need to test website responsiveness across different user agents, verify web layouts, or maintain completely separate browsing environments, PolyWeb provides full profile isolation—ensuring each profile retains independent cookies, local storage, sessions, and User-Agent headers to eliminate cross-session collision.

Key Features:

• Create and manage multiple distinct profiles with custom icons and theme colors.
• True Session Isolation: Each profile maintains independent cookies, cache, and local storage. Perfect for testing multiple user roles or isolated web sessions simultaneously.
• Clean specific profile data and cookies individually at any time for quick cache testing without affecting other environments.

【User-Agent Presets & Testing Tools】
• Built-in User-Agent presets: Mobile Browsers.
• Add, edit, and duplicate custom User-Agent strings to test responsive layouts, audit mobile web pages, and preview device-specific site rendering effortlessly.

【Seamless External Share Sheet Integration】
• Tap "Share" in any external application and choose PolyWeb.
• Instantly select which Profile and User-Agent to open the link with, facilitating quick testing and isolated URL inspection.

【Bookmarks & Efficiency Features】
• Organize profile-specific bookmarks for structured web testing and daily browsing.
• Customizable default search engine.
• Fast, responsive in-app webview engine with SSL security indicators and real-time load feedback.

【Privacy-First Architecture】
• Built with privacy at its core. Browsing sessions, cookies, and profile preferences are stored strictly on your local device—no remote data collection, tracking, or unexpected server syncing.
