Trust & Transparency

Yes, we're a .cn domain.
Here's why you can trust us.

We know .cn domains raise questions. Let us address them directly — with facts, not marketing.

🔓

100% Open Source (AGPLv3)

Our entire codebase is public on GitHub. Fork it. Audit it. Self-host it behind your own firewall if you prefer. No vendor lock-in — ever.

💳

Powered by Stripe

All payments processed through Stripe — the same payment infrastructure used by Amazon, Google, and Shopify. We never see your full card number. PCI DSS Level 1 compliant.

🔒

We Never Train on Your Data

Your prompts and completions pass through our gateway and nothing else. We don't log, store, or use your data for training. This is contractually binding in our DPA.

🏗️

Based in China. Built for the World.

Our .cn domain reflects our origin — not our allegiance. We're an independent startup that routes Chinese AI models (DeepSeek, Qwen) to global developers at unbeatable prices. No government affiliation.

📡

Data Residency Options

API traffic is routed through edge nodes in Singapore, Tokyo, and Frankfurt. EU customers can restrict processing to EU data centers. US-West edge coming Q3 2026.

🛡️

Independent Security Audit

SOC 2 Type II attestation in progress (estimated Q4 2026). Meanwhile, our open-source codebase is publicly auditable — and we encourage security researchers to report findings.

FAQ

Questions you might have
before signing up

Q: Why a .cn domain? Is my data going through Chinese servers?
Your API traffic does not touch mainland China. Our infrastructure runs on edge nodes in Singapore, Tokyo, and Frankfurt — the same regions used by global cloud providers. The .cn domain reflects where we're incorporated (cheaper to operate = lower prices for you), not where data flows. For EU customers, we offer data residency guarantees with processing restricted to Frankfurt only.
Q: Are you affiliated with the Chinese government?
No. We're an independent startup. FastAnchor is a private company with no government ownership, funding, or oversight. We contribute to and build on open-source software (AGPLv3). Our entire codebase is public. Our business model is straightforward: we make money by offering enterprise features, not by selling or mining data.
Q: What happens to my data — prompts, completions, API keys?
Prompts & completions: They pass through the gateway and are discarded immediately. We don't log, store, or train on them.

API keys: Encrypted at rest with AES-256. Usage statistics (token count, latency, cost) are stored for billing — nothing more.

We've designed the system so that even we can't read your conversation data. This is by design, not by accident.
Q: Why are your prices so low? Is there a catch?
Zero markup is our pricing model, not a promotional stunt. We make money on enterprise features (SSO, SLA, dedicated infra). The pay-as-you-go tier is pass-through pricing — you pay exactly what the model provider charges. We win when you upgrade to Enterprise, not by inflating per-token costs. This aligns our incentives with yours.
Q: Can I self-host this? Is the code really open source?
Yes. FastAnchor is built on New API, an open-source project with 18,000+ GitHub stars under AGPLv3. You can clone it, deploy it on your own servers, and never touch our infrastructure. The managed service is for those who don't want the ops burden — but you're never locked in.
Q: How do I know you won't disappear tomorrow?
Because you can run the code yourself. Even if FastAnchor the company ceased to exist, you could deploy the open-source codebase in under 30 minutes and keep running. We've intentionally made our platform replaceable — it forces us to compete on quality, not lock-in. Also: we're bootstrapped and profitable. We answer to our customers, not VCs.
