Power-off wipes all data
Known
A small device that watches your network traffic and forgets everything when you pull the plug. It runs a local dashboard at known.local. You don't need an account. Or any setup.

HOW IT'S
BUILT.
Known was built for one reason: a box that watches a network without talking back. No accounts. No cloud. A simple tool that forgets everything when you pull the plug. Then it became clear other people wanted the same thing.
No setup
Plug it into power and your network. It works. No app. No account. No email verification. The device is yours from the first boot. The only interface is a web browser pointing to known.local.
Local dashboard
The dashboard runs as a local web app talking to the Pico's HTTP API on port 8080. No tracking pixels. No CDNs. No third-party scripts. The OLED shows connection status. The buzzer beeps when a DNS query arrives.
Power off clears everything
Logs live in volatile SRAM on the Pico 2 W. When you cut the power, the data vanishes. It doesn't delete. It stops existing. Pull the USB cable and everything is gone.
Pull the USB cable and everything is gone.
MATERIALS
THE HARDWARE
The hardware is a Raspberry Pi Pico 2 W on a breadboard. OLED display, passive buzzer, USB power. No enclosure yet. No switches. No branding. Just the components that do the work, wired together and tested. The design will come later — right now the focus is on making it work.

Questions
Do I need to install anything?
No. Plug Known into power and your network. Open a browser and go to known.local. That's the whole setup.
Does Known block ads or filter traffic?
No. Known watches. It doesn't modify your network traffic. It tells you what's happening so you can decide what to do about it.
Where is my data stored?
In volatile memory on the device. Not on a server. Not in the cloud. When you pull the power, it's gone.
Can I read the firmware?
Yes. The firmware is open source. You can read every line, audit it, and verify that nothing phones home.
