Privacy

Your account. When you sign in with Google or Microsoft, we receive your name and email address and keep them to identify you. We set one cookie to keep you signed in.

Your mailbox. If you connect Gmail or Outlook, Brevity reads the messages it needs to handle the routines you set up, and creates drafts in your mailbox. The access tokens Google or Microsoft give us are encrypted before we store them.

What you give Brevity. Your chats with the assistant, the routines you write, the cases Brevity works on, and any files you or your contacts attach.

Brevity uses your email only to do the work you ask of it: sorting incoming mail into your routines, gathering the details a task needs, and drafting replies. Replies to anyone else are left as drafts in your mailbox for you to review and send. The only email Brevity sends on its own is to you, such as a question about a case.

We don't sell your data, use it for advertising, or let people read your email except to keep the service running, investigate a problem you report, or where the law requires it.

Brevity's use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements. We don't use Gmail data to train general-purpose AI models.

Brevity relies on a few providers, each only for its part of the work:

• Anthropic runs the AI models that read your messages and write drafts. Under its commercial terms, Anthropic does not train its models on what we send it.
• AssemblyAI turns speech into text when you dictate. Audio goes from your browser straight to AssemblyAI and never passes through our servers.
• Vercel hosts this site; Railway hosts our servers and database; Amazon Web Services stores files.
• Google and Microsoft handle sign-in and the mailbox you connect.

We keep internal logs of what Brevity did on each task, including message content, so we can find and fix problems. Access to them is limited to the Koi team.

You can disconnect your mailbox at any time from the account menu. Brevity stops reading it right away; for Gmail we also revoke our access with Google. You can also remove Brevity from your Google or Microsoft account settings.

To see what we hold about you, or to have your account and data deleted, email support@usekoi.com.

If we change how Brevity handles your data, we'll update this page and its date, and tell you by email before a significant change takes effect. Questions go to support@usekoi.com. Brevity is made by Koi Platforms, Inc., in New York.
