Privacy

Applies to cadmodeler.com

The short version: your drawings are yours, they stay on your machine by default, and nothing is measured about how you use this app until you ask it to be.

Your documents are local first

Work starts with no account. Projects save into your browser's own storage on your device and are never uploaded. Clearing your browser data deletes them; that is the deal, and it is stated in the app, not buried.

Accounts

If you create an account, we store the least that makes it work: your email address, a password held only as a salted hash (or a Google account linkage if you sign in that way), and the projects you choose to sync. Synced documents are stored so that you — signed in as you — can open them again. We do not sell account data, and there is no advertising of any kind to sell it to.

Payments

Paid plans are processed by Stripe. Card numbers go from your browser to Stripe and never touch our servers; we keep only Stripe's customer id and your plan, so your subscription can be found again.

Analytics are part of using the app

The product depends on knowing how it is used, so the app measures itself while you are signed in — it is a condition of the service, and it does not send anything about anyone who is not. It sends: visible-time heartbeats (so we know what is worth maintaining), a handful of named product moments (a sketch was drawn, a demo was opened), uncaught errors, and a session replay of the drawing surface.

Replays mask every input you type and refuse to record the sign-in panel and the welcome tour, so a replay shows the drawing, not your details. Each visit also records where it came from — the referring site and any campaign link — and the coarse shape of the device: browser, operating system, screen size, language, and time zone, plus the network address it arrived from. Nothing anonymous is collected: the tracker follows the signed-in account or it does not run at all.
