GUARDIANA ZERO · PREVIEW 0.9.0
The browser that shows you what it is saving you from.
GUARDIANA ZERO is a browser of our own for Windows. While you browse, you see at once which companies each page calls behind your back and which of them are cut off, with their country and the reason. The preview is free, with no account and no server of ours: everything happens on your computer.
What it does
- It cuts what websites call behind your back: trackers, advertising and the companies registered as data brokers. The website you open works; what is cut is the companies from outside.
- It shows you live. Each tab’s shield says how many companies tried and how many were cut off. “What was cut” shows every cut one by one, with the company, its country, the kind of request and the reason, and saves it as PDF or CSV.
- It removes tracking tags from addresses (utm, gclid, fbclid…) before they leave.
- Your marked data (your email, your phone…) does not go out to another company, not even turned into code the way ad networks do, and before a form sends it, it asks you.
- A mandate for your AI: a tab that only goes to the websites you name, for as long as you allow, and leaves a signed receipt of what it did.
- Redaction: prepares what you are going to ask an AI with your personal data struck out, and puts it back in place in the answer.
Download
Windows 10 or 11, 64-bit. It is a single file: no installation needed; save it in a folder and open it.
Preview 0.9.0, published on 9 October 2026. Before you open it, compare its hash with this table and with the public ledger, where it was written before the download existed (and in Rekor, entry 108e9186e8c5677a…cdf46f84).

Opening it for the first time
Windows may show “Windows protected your PC”, because the program does not carry a publisher certificate yet. Click “More info” and then “Run anyway”. Why this happens, and how to check the file before opening it, is explained on the install page: the signature is checked the same way as GUARDIANA’s.
What it does not do
- It does not make you anonymous to a website where you are signed in, and it does not stop every way of recognising a computer by its fingerprint.
- It is not a VPN: the websites you visit still see your IP address.
- It only sees what goes through the browser. What the other programs on the computer do is seen by GUARDIANA, the program.
- The web engine is WebView2, by Microsoft, the same as Edge’s: it comes with Windows 10 and 11 and Windows keeps it up to date.
What the preview is
While it lasts, everything is open and free. Afterwards, browsing, the live shield and cutting trackers will stay free for good; the mandate for your AI, marked data, redaction, receipts and “Who has my data” will move to the GUARDIANA subscription, the same one that protects the home. Anything that looks wrong, write it to hola@guardianagroup.com: it is corrected with a date.
