Cookie Policy
Explains which cookies and browser storage Cutter4D uses, why, and how to change your choice.
Last updated: 3 November 2026
1. In Short
Cutter4D uses only cookies that are STRICTLY NECESSARY for the service to work. We use no analytics, advertising or cross-site tracking cookies.
Strictly necessary cookies do not need consent; without them you cannot sign in or pay. Other categories run only if you switch them on.
2. Strictly Necessary Cookies
c4d_auth — keeps you signed in. First-party, readable only by the server (HttpOnly), sent over secure connections only; up to 30 days.
.AspNetCore.Correlation.* and .AspNetCore.Nonce.* — secure sign-in with Google or Microsoft. Deleted when sign-in completes (a few minutes).
Paddle — only when you open the checkout, our payment provider Paddle (merchant of record) may use its own cookies to process payments and prevent fraud. These are governed by Paddle's cookie policy. Prices are shown through our server, so browsing the site does not connect to Paddle.
3. Browser Storage
Some preferences are stored on your device (localStorage) and never sent to the server: c4d.locale (language), c4d.unit (unit), c4d.gcode (G-code settings), c4d.consent (your cookie choice and its date).
4. Analytics and Marketing
We do not use them today. If we add them, only the categories you allow will run; this policy will be updated and you will be asked again.
5. Changing Your Choice
Use the "Cookie preferences" link at the bottom of the page to change your choice at any time.
You can also delete cookies in your browser settings; deleting strictly necessary cookies signs you out.
