Effective date：August 10, 2026
Account data: email (LINE accounts may have none), display name, avatar, and sign-in method, obtained via OAuth/email. Usage content: your query text, conversation history, and selected classics scope. Usage and audit data: query counts/token usage, IP address, user agent, and timestamps (for abuse prevention, billing, and security auditing). Payment data: collected and processed by Paddle — we do not store your full card number.
To provide and improve the search service, maintain your account, prevent abuse and fraud, bill you, and comply with legal obligations. To improve the service, we use de-identified aggregate statistics (no identity, no raw query text) to understand common question types and gaps in coverage, and we collect the 👍/👎 feedback and suggestions you choose to give us. We do not use your conversations to train AI models: OpenAI, whose API we use to generate answers, does not train on API data by default per its policy; we do not train or fine-tune our own models either. Human review is opt-in only: we will not manually review your conversations without consent, and even if you opt in, review is limited to a de-identified sample of failure cases.
Supabase (database/auth), OpenAI (processes your query text to generate answers), Cloudflare (edge protection), Vercel (frontend hosting), Google Cloud (backend hosting), Upstash (caching), and Paddle (payments/tax).
The services above may process data outside your country (e.g., in the United States).
Free-plan conversation history is kept for the most recent 7 days; Premium history is kept indefinitely. Audit logs are retained as needed for security/compliance. Contact support@tcmlens.com to request deletion of your account and associated data.
Depending on applicable law (Taiwan's Personal Data Protection Act, GDPR, etc.), you may have rights to access, correct, delete, or restrict processing of your data. Contact support@tcmlens.com.
