Zero-network encryption: a tool that never phones home
Zero-network encryption tools do their work without contacting any server, ever. No telemetry, no licence check, no update ping. Elba is one of them, and you can verify the claim in ten seconds with your browser's DevTools.
Why ‘just one ping’ is not fine
A single outbound request leaks that you are using the tool, from what IP, and when. Over months, that metadata is a diary. Zero-network is the only setting that avoids writing that diary.
How to verify
Open Elba.html in Chrome. Press F12, click Network, then use the tool. If the list stays empty, the promise is true for that session.
Questions people actually ask
- Doesn't the browser check the URL?
- The browser loads the local file from disk. No URL to check, no request to make.
- How do I get updates then?
- You visit the site when you want to. Elba does not check for updates on its own.
Take the island
Elba is one HTML file. It runs locally in a Chromium browser, seals a folder with AES-256-GCM, never phones home, and becomes open source on 1 January 2030.
