ScreenGuard

ScreenGuard checks where a link goes before it opens, and gets stricter the moment you are sharing your screen. It is built around one idea: you should find out what a link opens before you click it, not after everyone on the call has seen it. WHAT IT DOES • Checks links before you click. Hover a risky link and a small warning appears next to it. Click one and the navigation stops before it starts, so you can decide. • Blocks risky pages however you arrive. Typed addresses, bookmarks, history, redirects and links opened from other apps are all covered — not just clicks. • Guards embedded frames. A risky page loaded inside an iframe on an ordinary site is stopped too. • Screen share mode. One switch before a call and ScreenGuard blocks personal pages — email, banking, chat — and blurs email addresses, phone numbers, card numbers and API keys on the page you are showing. • You are always in control. Every warning offers "Open anyway", once or permanently. Keep your own list of allowed and blocked sites. Nothing is censored, only paused. PRIVACY ScreenGuard does not have a server. There is nothing to sign in to and nothing to collect. • Your browsing history is never sent anywhere. It is not sent to us, because there is no "us" to send it to. • Risk checks run on your own machine against a local list and a set of local rules. • Sensitive content detection reads the page in the page. That text never leaves your browser. • No analytics, no tracking, no remote configuration, no ads. • Your settings, your lists and your protection history stay on this device, and the history page can clear them at any time. QUIET BY DESIGN On a normal website ScreenGuard does nothing at all. No badge, no banner, no overlay. You only hear from it when something looks risky — it should feel like a seatbelt, not an antivirus. WHAT IT IS NOT It is not a parental control, and it is not a censor. Every block can be overridden in one click, and every decision can be changed in Settings.
