Privacy Policy

1. What we collect

Your login email (or basic Google profile: email, name, avatar).

Login and usage records: sign-in time, IP, a device identifier (for the device limit) for security auditing, plus AI-chat usage counts.

We do not collect ID documents, card numbers, or contacts. WeChat payments happen on WeChat's side — we only see the received payment and the email you noted.

We use first-party anonymous analytics for traffic volume (page path, referrer, UTM tags, coarse region): no PII, no third-party cookies, raw IPs are never stored (truncated then one-way hashed for a daily anonymous count), no individual tracking; with Do-Not-Track enabled we collect nothing. The site operators' own visits are excluded as well (admin sessions are not counted, and owner devices can opt out via a first-party preference cookie).

2. How we use it

Sign-in and account security (anti-abuse, anti-sharing), member quota metering, and service improvement.

We do not sell your personal data and do not use it for third-party advertising.

3. Cookies

Used only for the login session and preferences (language, up/down color, theme). No third-party ad cookies.

4. Third-party processors

Cloudflare (network & protection), Resend (login-code emails), and AI inference providers (only the question text you actively send). Each is necessary to run the service and handles data under its own privacy policy.

5. Retention & deletion

Account and audit data are kept while the service operates; to delete your account or data, contact support and we will process it within a reasonable period.
