Privacy and Data

Caddie is built for engineers who work on confidential designs. This page says exactly where your data goes.

What stays on your PC

• Conversation history, kept for the History tab in %AppData%\CaddieAddin. You can turn it off, or delete all of it, in Settings.
• Your standards and file notes, the "How you work" setting and anything Caddie remembers about a file.
• Answers you rate. They're only shared if you copy a problem report and send it yourself.
• Your SolidWorks files. Caddie never uploads them.

What is sent to answer you

Each time you ask something, Caddie sends these to OpenAI through Caddie's relay, a small service that forwards requests and adds the API key:

• Your message and the recent conversation.
• Details of the open model: feature, sketch and dimension names and values, materials, errors, mass properties, and for assemblies and drawings their components, mates and views.
• A screenshot of the SolidWorks window, unless you turn screenshots off in Settings.
• Any image you attach to a message, such as a drawing, sketch or photo of what you want to model.
• Your name, standards and file notes, if you've set them.

When Caddie highlights a ribbon button or a field for you, it sends a screenshot to find it. With screenshots off, it can still point at FeatureManager items and menus.

What OpenAI does with it

• OpenAI does not use API data to train its models.
• Caddie asks OpenAI not to store conversations.
• OpenAI may keep requests for up to 30 days to check for abuse, as it does for all API use. See OpenAI's data controls.

What Caddie doesn't do

• No account, usage tracking, analytics or crash reporting.
• The relay doesn't log or keep the content of requests.
• Caddie changes your model only with your approval, and most changes can be undone.
