# Where your data goes

Tanso is self-hosted, so the honest version of this page is short.
Last updated August 7, 2026.

## Your Tanso instance

The engine runs on your infrastructure and has no hosted data plane. There is
nothing for us to subprocess.

| Service | Purpose | When |
|---|---|---|
| Your infrastructure | Everything. Customers, usage, billing state, and keys live in your database. | Always |
| Stripe | Payment collection and saved payment methods. | Only if you enable the Stripe adapter |
| Supabase | Receives an anonymous daily instance ping. A random instance id, version, entity counts, and a coarse event-volume bucket. No PII, no financial data, no keys. Payload documented verbatim in the README. | On by default; set TANSO_TELEMETRY_ENABLED=false to opt out |

## This website

tansohq.com is a marketing site. It never sees your Tanso instance's data.

| Service | Purpose |
|---|---|
| Vercel | Hosting, edge middleware, and performance analytics |
| PostHog | Conversion and error events. No session recording, no autocapture |
| Reddit | Ad attribution pixel |
| Fontshare | Font delivery (Satoshi) |
| Cal.com | Demo scheduling, only when you book a call |
