Privacy Policy

Margin reads the note, document, or on-screen content you choose to show it so it can help you. This content is processed locally on your Mac and is sent to an AI provider only when you ask Margin a question. We do not store your notes on our servers, and we do not use them to train any model.

Waitlist & account. If you join the waitlist or create an account, we store your email address so we can send your invite and product updates.

Diagnostics. The app may collect anonymous, aggregated crash and usage data to improve stability. This never includes the content of your notes.

When you ask Margin something, the relevant context is sent to an AI provider to generate a response. That provider processes the request to return an answer and, per its terms, does not use it to train its models. You can use your own API key to control this relationship directly.

We don't sell your data. We don't run ads against your content. We don't read your notes. Margin does, on your device, at your request.

You can unsubscribe from emails at any time, and you can request deletion of your account and associated data by contacting us at team@margin9.com.

If you live in California, you have the right to know what personal information we collect (your email address), to request that we delete it, and to not be discriminated against for exercising those rights. We do not sell or share your personal information. To make a request, email team@margin9.com.

We'll update this page if our practices change and revise the date above. Questions? Reach us at team@margin9.com.
