already known. is a cinematic privacy mirror that shows what your browser reveals before you type, click, sign in, or agree to anything. It turns browser fingerprinting signals like screen size, timezone, fonts, GPU, battery, tracker exposure, and behavior into a readable dossier, then points people to practical ways to reduce the leak.
Hey Product Hunt, I’m Cosmos.
I built already known. because most privacy education is either too technical or too boring to make people care.
This is a privacy mirror: open the page and it shows what your browser already reveals before you type anything. No account. No install. No scary permissions. It looks at ordinary browser and network signals like:
=>Browser and OS
=>Screen size and pixel density
=>Timezone and language
=>Fonts and canvas rendering
=>WebGL/GPU details when available
=>Battery status when exposed
=>Tracker-script exposure checks
=>Attention signals like scrolling, tab switches, movement, and clicks
The goal is not to shame people or pretend privacy is hopeless. The goal is to make the invisible visible, then give people a practical next step.
I also made an optional $7 Private Browser Fix Kit for people who want a simple PDF checklist for Chrome, Firefox, extensions, password managers, VPN basics, and data broker cleanup.
I’d love feedback on three things:
👉Does the first 30 seconds feel clear and surprising?
👉Which observation felt most unsettling or useful?
👉What privacy fix should I explain better next?
Thanks for checking it out.
