Privacy

Kiln is private by design

Kiln is local software that runs on your computer, not the cloud. Your dataset is stored locally on your own hard drive.

We don't have access to your dataset, and couldn't access it even if we wanted to.

All of Kiln's source code is on GitHub. Anyone can verify these privacy claims. Kiln's binary builds are built from the public source code, on public CI servers (Github Actions), and have verifiable checksums.

Requests to third party AI providers (like OpenAI or OpenRouter) are sent directly from your computer to those API providers. We can't see your keys or the data from those requests.

Desktop App Analytics

The Kiln desktop app collects analytics so we can understand how people are using it. This includes analytics like which pages are being visited, and which actions are taken in the app’s UI. Analytics are collected with Posthog.

• The Kiln Python library does not collect analytics. Only the desktop app’s user interface collects analytics.

• Analytics never include your dataset information, such as inputs to models, output from models, project names, etc.

• Analytics never include your API keys.

• Analytics may be associated with your email address if you register your email address.
