Email [email protected] and a person answers. Include your account email, the name of the app, and what you expected to happen; if something failed, the time it happened helps us find it in the logs.
Billing and account questions: [email protected]. Privacy requests, including export and deletion: [email protected]. Security reports: describe the issue and how to reproduce it, and we investigate every one.
Before writing in, two things solve most problems. If a published app looks wrong, republish it: changes stay private until you publish. If a custom domain is not resolving, check the DNS records on the domain screen, since certificates are issued only after the domain verifies.
The documentation at finestructure.ai/docs covers building, publishing, custom domains, entities and data, AI agents, and connecting Fine Structure to an AI assistant over MCP. See also contact, privacy policy and terms of service.
