GUPI GUARD Chrome extension security report

GUPI – Guarding User Privacy & Integrity GUPI is a privacy-first browser extension that helps you stay away from gambling content, intrusive pop-ups, and manipulative redirects without tracking you or sending your data anywhere. It works quietly in the background, blocking gambling-related sites and elements before they disrupt your browsing. No accounts, no data collection, no cloud processing. Everything happens locally on your device. The result is a cleaner, calmer, and more controlled browsing experience. What GUPI Does GUPI protects your browser from gambling traps using intelligent, multi-layer detection. Instead of relying only on static blocklists, it analyzes domains, page content, and behavior patterns in real time. This allows GUPI to catch both well-known gambling sites and newly created ones that try to disguise themselves or bypass traditional filters. All decisions are made instantly inside your browser. Your browsing activity never leaves your device. Key Features Smart Gambling Detection GUPI detects gambling content using a combination of domain patterns, page text analysis, redirects, pop-ups, and embedded iframes. This makes it effective even against sites that constantly change domains or wording. Pop-up and Redirect Blocking Intrusive gambling pop-ups, forced redirects, and hidden iframe promotions are blocked before they appear or steal your attention. Privacy-First by Design GUPI does not collect browsing history, visited URLs, or personal information. There is no analytics, telemetry, tracking, or third-party communication—ever. Fully Local Processing All detection runs locally in your browser. No external servers. No cloud scanning. No data sharing. Customizable Protection You control how strict the detection is. Choose conservative, balanced, or aggressive blocking—or fine-tune it yourself. Allowlist Support If a legitimate site is blocked by mistake, you can allow it with one click. GUPI will remember your choice and never block it again unless you decide otherwise. Clean, Modern Interface The extension interface is simple, fast, and distraction-free. You can see blocked activity at a glance and adjust settings without digging through menus. How It Works When you open a website, GUPI checks the domain for known gambling patterns. If the site passes, GUPI then scans the page content and behavior as it loads. If gambling signals cross the detection threshold, the site or element is blocked immediately and replaced with a clear explanation page. Everything happens in real time. Nothing is uploaded or logged. Privacy Transparency What GUPI Never Does • No tracking • No browsing history collection • No data uploads • No user profiling • No third-party services • No hidden analytics What GUPI Stores Locally • Your settings and preferences • Your personal allowlist • Aggregate block counters (numbers only, no URLs) You can remove all stored data at any time by uninstalling the extension. Who GUPI Is For • Users who want to avoid gambling content entirely • People seeking a distraction-free browsing experience • Families and shared devices • Work and study environments • Anyone who values privacy and control GUPI is a prevention tool, not a monitoring system. Performance and Compatibility GUPI is lightweight and optimized for modern browsers. It does not slow down page loading or interfere with normal browsing. Supported browsers include Chrome, Edge, Brave, Opera, Vivaldi, and other Chromium-based browsers using Manifest V3. Permissions Explained GUPI only requests permissions that are strictly necessary to block gambling content and store your settings locally. Each permission has a clear technical purpose and is never used for tracking or data collection. Final Note GUPI is built with one principle in mind: Protect users without invading their privacy. Install it once, and let it work quietly in the background.
