Substructure privacy & data

Your email address, and the name and avatar your identity provider returns if you sign in with Google or GitHub.

We store the Stripe customer and checkout identifiers, how many credits an organization has bought, and when they lapse.

A durable event log for every session: the messages in and out, tool calls and their results, subagent runs, approval steps, and per-turn token counts.

If you connect Slack, that includes messages in the channels an agent is present in, and the mentions and direct messages sent to it.

Ordinary server logs (request paths, timings, status codes, IP addresses), kept for debugging and abuse investigation.

Your model provider API keys, Slack bot tokens, and MCP OAuth tokens. These are encrypted with AES-256-GCM before they are written

To run the service you asked for: executing agent turns, keeping sessions durable across restarts, delivering webhooks, counting the credits you spend, and billing you.

To keep accounts secure and investigate abuse.

To understand which parts of the site lead to signups.

Sessions and their event logs are retained for 90 days , then removed.

Account, organization, and billing records are kept while the account is open, and afterwards only as long as we need them for tax and accounting.

Encrypted database backups are retained on a rolling basis, so deleted data can persist in a backup for a short period after it is gone from the live system.

Data is stored in the United States.

We use a small number of providers to run the service. Each receives only what its job needs.

To have the data itself erased rather than archived, write to support@substructure.ai .

We do not sell personal information, and we do not use the content of your agent sessions to train models.
