Before you install

Your AI runs locally. Here is what connects online.

Local processing

With local models, chat, image generation, and document search run on your computer. Model downloads need an internet connection; cloud providers and web tools send the data needed for those features to the services you use.

Clear data practices

The app sends version check-ins, including platform information and an installation identifier. Using Template Builder also shares generalized page templates with inputs stripped. No third-party analytics or crash reporting.
