Privacy & Advertising

Public marketplace browsing

Visitors can browse public CNC design previews and category pages without creating an account. Standard technical information such as browser type, approximate location, device information and page activity may be processed for security, performance and analytics.

Accounts and seller information

Signing in is required for seller uploads, protected purchases, downloads, ownership reports and account-specific services. Seller identity, listing information and evidence may be processed to review marketplace safety, ownership and compliance.

Advertising and cookies

When advertising is activated, third-party vendors including Google may use cookies or similar technologies to serve, measure and limit advertisements. Ads are intended for selected public content pages and are excluded from owner administration, upload, payment and protected-download workflows.

Advertising choices and consent controls will be provided where required. Google explains how it uses information from partner sites on its partner-sites information page.

Design ownership and reports

Uploaders must have the right to publish or sell their content. Watermarks, seller details and ownership evidence may be retained to investigate duplicate listings or rights complaints. See the CNC Marketplace Policy for the review and removal process.
