What you're buying
Every Untracked tool is a single HTML file. One file, no installer, no account, no background process. You download it after checkout, double-click it, and it opens in your browser — where it runs entirely on your own computer.
What happens after you buy
Right after checkout you get an email with subject "Your downloads are ready" containing your download link. No account is needed to receive it. Download the file, put it anywhere you like — desktop, a USB stick, an internal share — and open it.
How a single file can be a whole tool
The file contains everything: the interface, the logic, and any libraries the tool needs, bundled inside. Nothing is fetched from the internet when you use it. That's why it keeps working offline, and why it will keep working years from now — the file doesn't depend on any server staying online.
Will it expire?
No. There is no licence server, no activation, no phone-home. If the file opens, it works — today or in 2035.
Updates
When a tool you own is updated, you get the new version free: reply to your order email. Current versions of everything are listed on the changelog.
Try before you buy
The browser versions of every tool run free at tools.untracked.tools — nothing uploaded, ever. The download is the same tool with no daily limits, batch capability, and offline permanence.
