The vast majority of what you send to another continent travels through fibre cables on the seabed. Before the page has finished loading, it is already in another country. In the ZERO browser, the X-ray shows you which country and which company, and you decide what gets cut.
Every time you open a website with ads, what is known about you goes up for auction and the highest bidder wins. In the U.S., what each person does online, and from where, goes up for auction an average of 747 times a day. Your data travels to companies in countries you have never set foot in. In the ZERO browser, the X-ray shows you every auction: who bid, the declared price and who won.
The routes follow real submarine cables and land links to data centres. The exact path of each connection can vary. Figure: Irish Council for Civil Liberties, 2022.
Thousands of satellites carrying internet and data are circling the Earth right now. Every dot you see is a real one, where it is at this moment. If your connection goes out by satellite, your data goes up into space and back in milliseconds.
From the coast, buried fibre cables carry your data to the buildings where companies store it, combine it and use it. In the ZERO browser you see which company each connection reaches and which country it is in.
Advertising cutsubastia.exampleAllow
With Google or Brave, the ZERO browser shows you each website's advertising, tracking and cookie notices, and cuts them when you choose, with one switch per type. With Tor they are cut from the start. If you change your mind, another click brings them back.
How your data is sold
Every time you open a website with ads, what is known about you goes up for sale. Companies bid for the chance to show you an ad, and the highest bidder wins. It all happens while the page loads.

Program for Windows
The program you installed to protect you also connects to companies outside your computer. GUARDIANA tells you which ones, and in which countries.
It complements your antivirus. It doesn't replace it.
With a single button, the Antivirus examines your computer in depth: the protection you already have and what it sends, which programs use your microphone, your camera or your screen, the programs that came from the factory, what starts on its own and the telemetry your computer sends out. It only reads: it changes nothing, and what it finds stays on your computer.
In the program, under Orbit › Antivirus.
What GUARDIANA is
GUARDIANA brings together NÚCLEO, the ZERO browser, Orbit and Communications: to explore the internet's infrastructure, see what happens while you browse and send encrypted messages and files. It installs on your Windows PC and asks for no account.
01 · START
Go into NÚCLEO and tell it what you want to do. It takes you to each section.
02 · WATCH
In the ZERO browser, the X-ray shows you every connection: the company behind it, its country and what it is for.
03 · DECIDE
Cut the advertising or tracking you don't want with a switch. With Google or Brave, nothing is cut until you choose, and another click brings it back.
Services
ZERO BROWSER
Browse and see what each website connects to.
The website opens in a bubble on a GUARDIANA server, and only images reach your device. With Google or Brave, you decide what gets cut; with Tor, advertising and tracking are cut from the start.
ORBIT
Explore the internet's infrastructure.
A 3D planet with the networks that connect the internet.
COMMUNICATIONS
End-to-end encrypted chat, files and calls.
Write, send files and call whoever you invite, with no account or phone number. When you finish, the conversation is deleted on both sides.
NÚCLEO
Your way in and your guide.
Tell it what you want to do and it takes you to each section. It understands sentences with rules, not with generative AI, and it does not keep what you ask.
Communications · encrypted chat, files and calls
Chat and files with hybrid post-quantum encryption, and end-to-end encrypted calls. No account or phone: you join with a code.
Nine digits, valid for 10 minutes and for a single use. No account or phone number.
If both have the current version, ML-KEM-768 (FIPS 203) together with ECDH P-256. If the other person uses an older version, we tell you and do not continue without your permission.
Every message and every file chunk uses AES-256-GCM. An altered chunk fails verification and is discarded.
With Chrome or Edge they are written to disk as they arrive. In other browsers, up to 300 MB.
When a file arrives complete, the chat will confirm it. When you finish, the conversation is deleted on both sides.
For the most sensitive matters: ML-KEM-1024 and ML-DSA-87 in hybrid with P-384, a 256-bit link, four words to read aloud and the safety number, which can be compared at any time.
Encrypted end to end and always through the relay: neither of you sees the other's IP. With optional voice change, which changes the pitch, not the accent.
The relay sees the IP, the room and the volume, not the content. In the normal session, identity signatures are classical; in calls, the post-quantum layer is only added in Chrome and Edge, when both devices have it enabled.
For law firms, clinics, notary offices and advisers handling information that cannot leave the room.
