A five-minute answer to a question that shouldn’t cost you your machine.

Someone says they’re a recruiter, or a studio, or a client. They send a repo, a project file, or a document. “Just take a look and tell us what you’d change.” Opening it can be enough. An npm postinstall, a Unity editor script, a Blender or Maya scene, a Word or PDF wired to run something the moment it opens; all of it executes before you type a single command.

The person on the other end is counting on you being flattered, rushed, and not a security expert. That isn’t a fair fight, and antivirus was never built for it. You shouldn’t need a security background, or five days, to answer one question: a stranger sent me this. What happens if I open it?

The lure is universal, so the tool scales to everyone. What runs before you open it is the same question whether you make games or spreadsheets.

• It’s fingerprinted in your browser first. The bytes only leave your machine if we’ve never seen that exact content before.
• If it does upload, it lands in temporary storage just long enough to be read once, then a storage-level rule deletes it automatically, with no human and no code that has to remember to.
• What we keep is a content fingerprint and the findings, never your source. Short evidence snippets around a flagged line are the only exception, so the report can show you what it saw.
• Everything runs on servers in the EU, under GDPR, never in the US.
• The scanner itself doesn’t profile you and sets no tracking cookies of its own. How it’s funded is spelled out just below, in plain sight.

This isn’t a startup harvesting you, and it isn’t venture-funded. It’s one person and one small server. Free, because someone staring anxiously at a stranger’s zip shouldn’t have to pay, or sign up, to find out whether they’re about to be robbed. The tool is never the thing being sold.

But servers cost money, and someone has to pay for them. Two things keep the lights on, and neither one ever touches what you scan:

• Donations. If it saved you a scare, a coffee helps cover the hosting. That’s the honest ask, and it comes first.
• Ads. To keep this free, with no paywall and no login, the site may one day carry ads. They would live on the page, not inside the scanner: your file and its findings are never shared with an advertiser, and the results screen stays ad-free. I’m still choosing an ad partner that fits all of this, so nothing runs yet.

I’m being upfront because a security tool that hides how it makes money isn’t one you should trust. If donations ever cover the bills on their own, the ads never happen. Whatever pays for the servers, it never gets to see what you came here to check.
