How to install WhoSees on Windows
- Click Download for Windows to get
WhoSees-Windows-Setup.exe(about 190 MB). - Run the installer. Windows shows a blue "Windows protected your PC" screen: click More info, then Run anyway.
- Choose where to install it and click Install.
- Open WhoSees from the Start menu and click Start live view.
Windows shows that warning for any new program that isn't code-signed yet, meaning it doesn't carry a digital signature proving who published it. It doesn't mean anything is wrong with WhoSees. WhoSees has applied for free code signing from the SignPath Foundation; once approved, the installer will be signed and the warning fades as more people install it.
Standard and Deep mode
| MODE | WHAT IT DOES |
|---|---|
| Standard | No administrator rights needed. Shows apps, companies and places from Windows' own connection list. |
| Deep | Asks Windows for permission (a Yes/No prompt) each time you press Start. Adds website names and catches every connection, even ones that last a split second. Still only reads where data goes, never what's inside it. |
Check your download
The Windows installer is built automatically by GitHub from the public source code, never on a personal computer. To confirm your copy wasn't changed, open PowerShell in your Downloads folder and run Get-FileHash WhoSees-Windows-Setup.exe, then compare the result with SHA256SUMS.txt.

Questions
Why does Windows say 'Windows protected your PC'?
Windows shows this for new programs that aren't code-signed yet. It doesn't mean anything is wrong with WhoSees. Click More info, then Run anyway. WhoSees has applied for free code signing from the SignPath Foundation.
Can WhoSees block apps or trackers?
Yes, while a live view runs: tap Block on an app, a company, a website or a country, or switch on Block all trackers and ads. Blocks end when you press Stop unless you choose Keep. On Android nothing else is needed.
Does WhoSees read my traffic?
It reads where your data goes, never what's inside it. Almost all traffic is encrypted, and WhoSees doesn't open it.
