No account, no analytics, no telemetry. The program makes exactly two network requests in its whole lifetime, and both of them are written out below.
The program asks raincleaner.eu/v1/version whether a newer build exists. The request carries nothing about you or your machine. Like any web server, ours writes the requesting IP address and the time into its log.
If there is no network, nothing happens and nothing nags.
Then, and only then, the key is sent together with a fingerprint of the machine. The fingerprint is a SHA-256 hash of the Windows machine GUID, the size of the system disk and the computer name, shortened to 32 characters. A hash goes one way: none of those three can be read back out of it, and it says nothing about the person at the keyboard.
Pro is not on sale yet, so in practice nobody sends this today.
The scan results and their explanations — the knowledge base is a file on your disk, not a service. The protection journal, which records paths and command lines and never the contents of a file. Anything moved to quarantine, encrypted locally with a key that never leaves the machine. Every boost and every network change is written down locally so it can be undone.
None of it is uploaded, and there is no button that would upload it.
Cloudflare sits in front of the site and records IP addresses as part of serving it. Our own server counts downloads from its log: one address counts once per six hours per file, which is the only reason the counter on the site is a real number and not a flattering one.
There are no tracking cookies and no advertising scripts. The one cookie is rc_lang, written only when you pick a language by hand so that your choice wins from then on.
Drivers are searched for and installed through Windows Update — Microsoft's own channel, under Microsoft's own terms. Nothing is hosted, mirrored or repackaged here. A manufacturer's page opens in your browser only when you click it.
Write to support@raincleaner.eu. Since nothing identifying is stored, in most cases the honest answer is that there is nothing on file to hand over or delete.
