Qimena ("we", "the Site", qimena.com) respects and protects your privacy. This policy explains what we collect, how we use and safeguard it, and the rights you have. By using the Site you agree to this policy.
1. Information We Collect
Account data: username, email, and password (stored encrypted — we never see the plaintext).
Chart inputs: the name/alias, gender, birth date and hour, birth longitude, and focus topic you enter, used to cast and interpret your Qi Men Dun Jia chart.
Usage data: an anonymous session identifier and feature events (open, cast, ask), used to improve the product and not identifying you personally.
Visit source: on your first visit we note on your device which link parameter (such as utm_source) or which website's domain brought you here (never the full address), and attach it to a few events (your first visit, opening the app, signing up, paying) to learn which channels work. It contains no personal information.
Push subscriptions: if you enable daily reminders, we store your browser push endpoint, language preference, and time zone.
Reading ratings: when you rate an AI reading as helpful or not, we store your rating, any comment, and the question and AI reply you rated, used only to improve the readings. They are deleted with your account.
Sign-in devices: to protect your account we record the browser and system type you sign in with (for example "Chrome · Windows"), the approximate country or region, and the time. We do not store your IP address. When you sign in from a new device we send you an alert email. This is deleted with your account.
Invite reward checks: to stop one person claiming invite rewards with several email addresses, at sign-up and sign-in we store a keyed, one-way network fingerprint (not your IP address itself, and it cannot be turned back into one). It is used only to tell whether an inviter and the friend they invited come from the same network. It is deleted with your account.
Local storage: we use browser localStorage for login state and preferences. We use no third-party advertising or tracking cookies.
2. How We Use It
We use information only to: provide charting and AI interpretation, maintain your account and subscription, send reminders you opt into, and improve the product. We do not sell your personal information.
3. Third-Party Processors
Cloudflare: site hosting, database (D1), and content delivery.
AI providers: your questions and chart summaries are sent to large-language-model services (e.g. Google Gemini, OpenRouter, Cloudflare Workers AI) to generate interpretations. Please do not enter sensitive personal information in the chat.
Payments (if applicable): subscription payments are processed by Stripe; we do not store your card details.
4. Data Storage & Retention
Data is stored on Cloudflare's global infrastructure. We retain data for the life of your account; after you close it, we delete or anonymize your personal data within a reasonable period.
5. Your Rights (GDPR / CCPA)
You can delete your account yourself at any time under Settings → Delete account on the website or in the app (your password is required). This deletes your account, saved charts, push subscription and feedback and cancels any subscription; payment records are kept without your identity for accounting. You may also access, correct, export, or delete your personal data, and object to or restrict certain processing. To exercise these rights, email the address below and we will respond within the period required by applicable law. California residents may request the categories of information we collect and ask for deletion; we will not discriminate against you for exercising your rights.
6. Children's Privacy
The Site is not directed to children under 13 and we do not knowingly collect their information.
7. Changes & Contact
We may update this policy from time to time; material changes will be posted on this page. Questions: [email protected].
