Privacy and what leaves your machine

What stays on your computer, and the little that doesn't.

What stays.

Your code and your agents' work Repos, diffs, transcripts and logs stay on your computer, under ~/.overhand and your own folders.
Your keys In your keychain, or the file you opted in to. Where things run.

To your model What your agents send to the model provider you chose, just as they do without Overhand. A local model's prompts stay on your computer.
To GitHub and your tools Through your own sign-ins: gh for pull requests and issues, and any tracker, error service or notification you connect, such as ntfy or a status update's webhook.
A release check Once a day Overhand asks GitHub whether a newer release is out.
On Pro and Team Your sign-in, your computer's link and your plan go to the relay at app.overhand.dev; on Team, the team's metadata too. What the relay does and doesn't see.
