Millr collects nothing.

The skill

Millr runs inside your own Claude account, under Anthropic's terms and your account's settings. Millr never receives your part or your drawing.

Your part and drawing go only to Claude, under your Claude plan's terms. On Team and Enterprise, Anthropic does not train on your chats by default. On Free, Pro and Max, whether it may is your choice in your Claude privacy settings, apart from chats flagged for a safety review. Rating a chat with the thumbs buttons sends that chat to Anthropic as feedback, which Anthropic may use to train its models on any plan. If your part is under NDA or export control, follow your company's rules for using Claude.

The review page Millr builds carries everything it needs and fetches nothing from the network. To measure your part, Claude may install an open-source CAD library: in Claude's sandbox on claude.ai and Claude Desktop, or on your computer in Claude Code.
