Privacy Policy

Who we are

ChinaCopilot (“we”, “us”) operates https://chinacopilot.app — navigation checklists, place-name helpers, and optional paid tools (for example contract risk notes and lodging worksheets).

Contact: support@chinacopilot.app

What we collect

Depending on how you use the site, we may process:

• Usage analytics (for example page views and product events) via Google Analytics or similar, if configured — typically IP-derived approximate location, device/browser type, and referrer.
• UTM and campaign parameters stored locally in your browser so we can attribute visits.
• Content you voluntarily submit (for example interest forms, dining/venue reports, contract page images for paid audit, lodging worksheet fields).
• Payment and entitlement signals from our merchant-of-record (Lemon Squeezy) — we do not store full card numbers on our servers.
• Optional Telegram identity if you open tools from a Telegram Mini App menu button.

How we use data

We use data to operate and improve the free navigation product, deliver paid unlocks, prevent abuse, and respond to support requests.

Contract images and worksheet fields are processed to generate the tool output you requested. Do not upload content you are not allowed to share.

Cookies and local storage

We use browser local storage for stage preferences, share/UTM context, and paid entitlements on this device. Clearing site data removes local unlocks; keep your Lemon receipt email.

Third parties

We rely on processors such as Vercel (hosting), map/search providers (for example Amap Web Service for place lookup), analytics providers, Lemon Squeezy (checkout), and AI providers when you run contract audit.

Those providers process data under their own terms. We do not sell personal data.

Retention

Serverless deployments may not persist every form submission. Analytics and merchant records follow each provider’s retention. Local browser data remains until you clear it.

Your choices

You can refuse analytics via browser controls, clear local storage, and email support@chinacopilot.app to ask about access or deletion of data we hold that identifies you.

Changes

We may update this policy; the “Updated” date at the top will change. Continued use after an update means you accept the revised policy.
