Same account, same Safari tab, minus the scroll trap. ZERO FLASH Curb loads blocking rules before the page paints, so the feed never appears, not even for a split second. A SIMPLE GUIDE Where the feed was, Curb can show a short on-page guide pointing you to what still works on that site. Toggle it per site in the Safari toolbar popup. YOU STAY IN CONTROL One switch per site. Turn any platform on or off anytime from Safari’s toolbar, no digging through settings. PRIVATE BY DESIGN No accounts. No servers. No analytics. No tracking. Everything runs on your device. App Store privacy label: Data Not Collected. PAY ONCE — EVERYTHING INCLUDED One purchase unlocks all six platforms. No in-app purchases. No subscriptions. No free trial tricks. IMPORTANT Curb works in Safari on youtube.com, reddit.com, instagram.com, facebook.com, linkedin.com, and x.com and not inside the native YouTube, Instagram, Reddit, or other apps.
