Agent Workbench · Product privacy
Privacy for the
free companion.
The companion saves your account details and setup progress. Your agent packages and conversations stay in the Microsoft service where you use them.
Scope
Celest AI, Inc. operates the Agent Workbench companion. This notice applies when you sign in, create or manage a companion account, save setup progress, or contact us about the companion.
The companion does not receive your agent packages, Copilot conversations, or Microsoft 365 tenant content. When you use the Agent Workbench plugin inside Cowork or Microsoft 365 Copilot, Microsoft's processing is governed by your applicable Microsoft agreements. The separate public Celest website notice describes the marketing website's analytics.
What we collect
- Sign-in information: Microsoft's stable identifier for your account and the name and email address Microsoft supplies, when available. These let us recognize you on a return visit.
- Account details: the display name, contact email, and optional organization name you confirm or edit.
- Setup progress: whether you choose Cowork, Copilot, both, or neither yet, and the setup steps you mark complete.
- Account records: when the account was created or updated, the terms version you accepted, and the acceptance time.
- Session information: temporary records that complete Microsoft sign-in and keep your browser signed in.
- Support: your sender address, message, and information you choose to include when you email us.
The companion requests basic Microsoft sign-in information only. It does not request access to your mail, files, contacts, or other Microsoft Graph data. We do not retain Microsoft access or refresh tokens.
How we use it
We use these records to authenticate you, activate free access after your confirmation, restore your saved progress, manage your account, respond to support requests, and operate the service. Setup steps are recorded when you mark them; the companion does not monitor your Microsoft installations.
The companion does not use account details for advertising or model training. It has no advertising trackers or optional analytics cookies.
Retention and cookies
We keep your account details and setup progress while your account remains open. Deleting the account removes those records from the active companion database and revokes its sessions.
A sign-in attempt expires after 10 minutes. A companion session expires after 7 days or when you sign out or delete the account. Expired sign-in and session records are scheduled for cleanup each hour. The browser uses necessary cookies for these functions; blocking them prevents sign-in.
Cloudflare-managed backups follow Cloudflare's retention and deletion processes, so removal from the active database does not erase every backup copy immediately. Support correspondence and records needed for legal or security obligations are kept only as long as reasonably needed for those purposes. They are separate from the account records removed by the self-service delete action.
Your choices
You can correct your account details, sign out, or delete your companion account from Account settings. Deletion does not delete your Microsoft account or uninstall a plugin. Signing in again after deletion starts a new companion account only if you confirm creation again.
For access, correction, deletion, or another privacy request, contact [email protected]. We may need to verify that a request concerns your account. Please include only the information needed to explain the request.
We will publish changes to this notice with a new version date. If the way we use account information changes materially, we will provide notice through the service or your account contact address.
