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).
Your conversations with the AI assistant (the questions you send and the assistant's replies) are recorded server-side, used for quality improvement and issue review, and automatically deleted after about 90 days.
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.
Used only for the login session and preferences (language, up/down color, theme). No third-party ad cookies.
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.
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.
