Privacy
The short version: we keep what we need to run your account and your machine, nothing more, and we delete it when you delete your account.
Alpha policy · last updated 15 October 2026
What we store about you
- Your GitHub identity: your GitHub user id and login, and the name and email address GitHub shares, if any. Sign-in asks GitHub for no repository access.
- Sessions for the apps you're signed in to, stored as one-way hashes.
- Your machine's record: its plan, state and network address.
- A task index: each task's id, status, repository and pull request link, so the apps can list them. The control plane does not store your prompts, transcripts or code.
- Push notification tokens for your devices, so we can send approvals and task updates.
Your machine
Your code, your agents' work and the credentials you give your agents live on your machine, not in our database. Agent credentials are kept in an encrypted vault on the machine. We don't look at what's on your machine. We'd only access it to keep the service running or if the law required it, and we'd tell you if we did, unless the law forbids that.
Your AI providers
You sign in to Anthropic, OpenAI and the other agent vendors with your own account or key. Your prompts go from your machine straight to them, under your agreement with them. We don't see or store that traffic.
Who processes data for us
- Hetzner hosts your machine and our servers, in its EU data centres.
- GitHub for sign-in and, if you connect it, for your repositories.
- Apple delivers push notifications.
- Cloudflare provides DNS.
- Resend sends our emails and receives mail sent to quartz.computer addresses. When you email us, Resend passes your message to our team's inbox. Our servers forward it without storing it.
Backups
During the alpha, machines are not backed up. Keep your work pushed to GitHub. When backups arrive, this page will say where they're kept and for how long before they're switched on.
Deleting your account
You can delete your account at any time in Settings in the Mac or iPhone app. It takes effect immediately: we sign you out everywhere, delete your machine, revoke our GitHub access, and erase your records. We keep only what the law makes us keep, such as invoices once paid plans exist.
