Sub-Processors

To operate Symphoniee, we use the third-party service providers below. Each processes data only to provide its service to us, under contract, and all process data in the United States.

• Stripe — payment processing and subscription billing.
• Vercel — application hosting, delivery, and edge network.
• Google Firebase (Google Cloud) — authentication, database, and file storage.
• Google (Gemini) — generating AI insight reports from session responses, when a presenter requests one.
• Resend — transactional email (verification, receipts, download links).

We’ll update this list when we add or change a sub-processor.
