DOWNLOAD

Kionel for a PC that never goes online

One HTML file. Copy it to the isolated PC through your approved route, open it in the browser, and it runs: no installation, no network, no administrator rights.

1. Check the file before it goes anywhere

Download it on a PC with internet access and compare its SHA-256 with the value above.

Or drop it on the SHA-256 checker and paste the value above. If it does not match, do not use the file.

2. Put it on the offline PC

1. Copy the file through the route your site already approves: a managed USB stick, a transfer kiosk, a software deployment tool.
2. On the offline PC, open it with Chrome or Edge 137 or later (right-click → Open with). Windows 10 and 11 can run these; Windows 7 and 8.1 cannot.
3. The first line says Offline package 1.0.1. For business features, press Load licence file once and pick kionel-license.json.

Keep the file somewhere users cannot write to, for example a read-only folder, so the version that was checked is the version that runs.

What the package does

It is the sending side of Kionel, complete:

• Sending to a receiving device with a typed code or a receiver card: no camera needed on this PC.
• Live QR codes, and the dense recording mode for larger files.
• Signed dispatch records, the seal (proof without transfer), printed reports.
• Licence loading from a file or pasted text. Checked on the PC itself; nothing is contacted.

Not in this version: the colour code. The receiving device opens kionel.com in its own browser as usual.

Why it never updates itself

A validated system is validated at one version. A web page that changes under the user cannot be validated; a file with a fixed hash can. Every new version is a new file with its own name and SHA-256, listed on this page with the commit it was built from, and older versions stay downloadable. What changed is in the changelog.

Earlier versions

Kept so that a validated installation can be re-checked or restored.
