A sub-processor is a third party that Synheart uses to run Synapse, and that may process your data as a result. Synapse uses as few as possible. This list was built from Synapse’s production code and infrastructure, checked in November 2026. Logging, metrics and secret storage run mainly on infrastructure Synheart hosts in its own AWS account; see the note on error alerting below.

Sub-processors

Not sub-processors

No language model for search or Ask. The Search page returns cited excerpts found by search, and the Ask page lists decision records; no model writes an answer. The only model that writes text is the one behind explanations (Together AI, above), and only when explanations are turned on. Monitoring we checked and found off. As of 2026-11-10 the dashboard’s Sentry error reporting has no production key, so it sends nothing; no application log group forwards to Better Stack, which hosts only the public status page; and no metric stream to Grafana Cloud exists. Each would be added here before it is turned on. Identity providers you choose. If people sign in with Google, GitHub or Apple, that provider confirms their identity to Synheart. These are your users’ choice of sign-in, not services Synheart uses to process your data. Tools you connect. GitHub, GitLab, Slack, Notion, Google Workspace (Calendar and Drive), Microsoft 365, Linear, Jira, Zoom, and AI vendors (Anthropic, OpenAI, Cursor, GitHub Copilot) are your own services. You authorize Synapse to read from them; Synheart doesn’t send them your data. Synapse writes back only when you ask it to (for example, when an agent opens a pull request to record a decision), and in repositories where you install the Synapse GitHub App it posts a “Synapse decisions” check on pull requests. What Synapse reads from each is on the Security overview.

Changes to this list

Synheart updates this page before a new sub-processor starts processing customer data. To be told about changes, or to ask about a sub-processor, email security@synheart.ai. Your DPA sets the notice period and how to object.
