Umbric vs Bifrost Browser

Website data does not carry over between sessions — and the moment someone might look, the whole screen hides. • Reduces ads and trackers with network rules and on-page cleanup • Cookies, cache, and web storage do not persist between sessions; history stays on your device • The moment you switch away, the screen auto-camouflages • One-tap wipe clears the categories you choose There are moments you'd rather not show your screen to anyone. A stranger's glance on a packed train, someone walking behind you in a café, the seconds your phone sits unattended, a brief hand-off to someone else. In those moments, leaving no trace and showing nothing matter. Umbric leaves no trace and shows nothing — an iOS browser that keeps cookies, cache, and web storage out of persistent storage, blocks ads and trackers, and auto-camouflages its screen when moved to the background. Key features - Non-persistent storage for cookies, cache, and web storage (wiped between sessions) - Browsing history stays on-device only, never sent externally — wipe it with one tap - Private Mode: Face ID-protected, separate space for bookmarks and history - Two-layer ad & tracker blocking (network rules + DOM-level removal) - Stops pop-ups and ads that open new tabs on their own - Fingerprinting protection (Canvas / WebGL / AudioContext / Navigator) - HTTPS enforcement, JavaScript dialog blocking, camera / mic access denied - One-tap wipe: clear history, cookies, cache, and more by category - Focus Filter integration: switches into Private Mode automatically - Recently closed tabs, in-page search, reader mode, video download About the name "Umbric" combines Umbra (Latin for shadow) with the idea of a deft, well-considered move. Sit beside you without taking up space, slip out of sight the moment a glance comes near — your privacy, kept by your own hand. Leaving no trace isn't about deceiving anyone. It's about taking care of your own privacy. No trace. Nothing shown. — Umbric.
