What we collect, and why

Website statistics

We count visits with Umami, a self-hosted analytics tool running on our own server at stats.chantocnc.com. It sets no cookies. It builds an anonymous session identifier from your IP address, browser user agent and a salt that changes every month, so a visitor cannot be recognised across months; the IP address itself is not stored.

It records which pages are viewed, the referring site, your country, region and city, your browser, operating system, device type, screen size and language, and two clicks: downloads (by platform) and the buy button. There is no cross-site tracking, and nothing is sold or shared.

Downloads

Download links go through our license server. It records your IP address, the platform of the installer, and the page or campaign that sent you here.

That is kept for about two days, so a trial started from the same connection can be linked to the download. Then it is deleted. Only the source, campaign and landing-page labels (for example “youtube.com”) and the platform name stay with the trial.

The app

When a trial starts, the app sends a machine fingerprint (a hash of hardware identifiers) and its platform. Activating a license sends the license key, the fingerprint and the app version; refreshing or releasing it sends the key and the fingerprint. An update check sends the platform, processor architecture and installed version, plus the license key if there is one.

The server stores the trial window and the activations per license. That is how the trial, the three-machine limit and update entitlement are enforced. The app sends no usage data.

Purchases

Paddle is the merchant of record. Checkout happens on Paddle’s pages, and the renewal page on this site loads Paddle’s checkout script, so Paddle’s privacy policy applies there and Paddle may set its own cookies.

We receive the transaction id and the email address your license key is sent to.

Email

License keys are sent from licenses@chantocnc.com. Support questions go to support@chantocnc.com.

Who holds the data, and where

ChantoCNC Studio LLC runs this website, the license server and the mail server, and is the data controller for everything described above. Paddle is a separate controller for the payment data it collects at checkout.

All three services, and the Umami statistics, run on one server located in Boston, Massachusetts, United States. Your data stays there; we do not pass it to anyone else.
