Cronos is the browser that protects you - not just online, but in real life. With Stealth Screen technology, built-in ad blocking, and zero tracking, this is browsing as it should be. What makes Cronos different: Stealth Screen - Privacy Beyond the Screen Your front camera detects when someone is looking at your screen. The moment it happens, your content is instantly hidden. No more tilting your phone or hiding your screen on the bus. History Password - Lock Your Past Set a password to protect your entire browsing history. Nobody gets access to your history without your permission. Not friends, not family, not anyone. Stellar Mode - Media That Never Stops Audio and video keep playing when you leave the app, switch to other apps, or lock your screen. Your music, podcasts, and videos never get interrupted. Built-in Ad & Tracker Blocker Ads, pop-ups, and invisible trackers are blocked automatically. Pages load faster, look cleaner, and nobody follows you around the web. Auto Cache Clearing Your browsing data is cleaned up automatically on a schedule you choose. Your device stays fast and your privacy stays intact — without lifting a finger. Secure Local Password Vault Save and autofill passwords securely. Everything is encrypted and stored locally on your device. Your credentials never leave your phone. 50+ Themes & Customization Colors, fonts, wallpapers, buttons - customize everything. Make Cronos look and feel exactly the way you want. Tab Swiping Switch between tabs by swiping left or right, just like flipping through a book. Fast, intuitive, natural. Smart Shortcuts Pin your favorite sites for one-tap access right from your start page. Built on Transparency We believe trust is earned. We collect zero personal data. No surprises, no hidden tracking. Cronos is not just another browser. It's a fresh take on how browsing should feel — fast, beautiful, and respectful of your privacy. Come for the privacy. Stay for everything else.
