Kaixon Sub-processors

The providers who help us run Kaixon

Last updated: 23 September 2026 · This is the authoritative list referenced by our Privacy Notice and our customer Data Processing Agreement.

Kaixon runs on a deliberately small set of service providers ("sub-processors"). Each one is bound by a data processing agreement, and we remain fully responsible to you for what they do with data on our behalf. We do not sell personal data and we do not use it for third-party advertising.

Providers that can touch subscriber vault data

Provider	What they do for you	Where	Transfer safeguard
Supabase	Secure database, functions and storage — where your vault records live	EU (Frankfurt, Germany)	US parent under Standard Contractual Clauses (SCCs)
Cloudflare	Content delivery, serving your dashboard and reports, PDF rendering	Global edge network	SCCs / EU-US Data Privacy Framework (DPF)
Resend	Transactional email — your report link, sign-in links, confirmations	Sent from the EU (Ireland); the email itself, plus metadata and logs, stored in the US	SCCs / EU-US Data Privacy Framework (DPF)
Anthropic (Claude)	Powers the AI help chat in your account. It receives the messages you type into the chat and nothing else — it has no route to your vault, your answers or your reports.	US	Standard Contractual Clauses (SCCs), incorporated into Anthropic’s commercial terms

Where “sent from” differs from “stored in”. For email, the sending region and the storage region are not the same thing. Where a provider sends from one place and keeps the delivery record — the message itself, the email address, subject line and timestamps — in another, the “Where” column names both.

Providers that run the rest of Kaixon

Provider	What they do	Where	Transfer safeguard
Stripe	Payments and invoicing for paid plans — we never see your card data	US	SCCs / DPF
Kit (ConvertKit)	Waitlist and product-update emails	US	SCCs
Make.com	Relays waitlist sign-ups only (being retired)	EU (eu1)	— (EU relay; provider’s own storage not verified)
Google Workspace	Our business email and document storage	US	SCCs

Where AI sits, and where it doesn’t. Kaixon’s scoring is deterministic software: no AI model sees your assessment answers. One AI does sit in the product — the help chat in your account, run by Anthropic — and it receives only what you type into it. Separately, our providers have providers too, and some of those offer AI services; that sits on the path that delivers your email — the address it goes to, the subject line, the timestamps — not on your assessment content.

Changes to this list. Before we add or replace a sub-processor that can touch subscriber vault data, we update this page and email subscribers at least 14 days in advance. If you have a reasonable data protection objection, our Data Processing Agreement explains your options.
