These are the companies that help us run Brekfuz and may handle customer data in the process. Each is bound by contract to protect it and to use it only to provide their service to us.
We give customers at least 30 days’ notice before adding a new subprocessor. To be notified, email support@brekfuz.com.
| Vendor | What they do | What they handle | Location |
|---|---|---|---|
| Amazon Web Services | Hosting, database, storage, login, email delivery, encryption keys | All customer data | US (Ohio) |
| Turbopuffer | Search index | Message and event text, and the numerical representations used for search | US (Iowa) |
| Neo4j Aura | Relationship graph | Names, email addresses, and connections between people and topics | Region confirmation pending |
| Vendor | What they do | What they handle | Location |
|---|---|---|---|
| OpenAI | Generates answers, and creates the numerical representations used for search | Excerpts of email, calendar and Slack content, plus the user’s question | US |
| Cohere | Re-ranks search results for relevance | The user’s question and short summary text | US |
| Anthropic | Backup answer generation, off by default | Same as OpenAI, when enabled | US |
None of these providers use Brekfuz customer data to train their models. This is required by their standard API terms, and separately required of us by Google’s Limited Use rules for Gmail data — set out in our Privacy Policy.
| Vendor | What they do | What they handle | Location |
|---|---|---|---|
| Composio | Manages the connections to Slack, GitHub, Jira, Linear and Fireflies | Access credentials for those tools, and the data passing through them | US |
| Resend | Sends invitation and notification emails | Recipient name, email address and company name | US |
Brekfuz does not use any third-party error tracking, analytics or application monitoring service. Our system metrics stay inside our own AWS account and do not include customer content or identifiers.
Enterprise customers can connect Google Workspace using domain-wide delegation, where your own Workspace administrator grants access directly with credentials you control. On this setup, Composio is not involved in the Gmail or Calendar connection at all.
We recommend this option for enterprise deployments — see section 9 of the Security Overview.
