Privacy Policy for ChiScan
Last updated: August 1, 2026
This Privacy Policy explains how ChiScan ("the App," "we," "us") handles information when you use our Service.
By using ChiScan, you agree to the practices described here. You must be at least 13 years old to use this Service.
What information we collect
Information you provide during setup: your goal (money, love, or health focus), gender, birth date, and home type. This is used only to compute your personalized Kua number and tailor your scan results. This information stays on your device — we do not operate a server that stores it.
Your room photos: When you scan a room, the photo is sent to Google's Gemini API for analysis. We do not store your photos on any server we control. The photo and the scan results (score, detected issues) are saved locally on your device only, so you can view your history — they are not uploaded anywhere else by us.
Purchase and subscription information: If you subscribe to ChiScan Premium, our subscription management provider, RevenueCat, receives your App Store transaction information and an anonymous identifier to manage your entitlement and subscription status. We do not see or store your payment card details — Apple processes all payments directly.
Device information: Standard technical information (device model, OS version) may be collected automatically by Apple and our service providers (Google, RevenueCat) as part of normal app operation and fraud prevention — not for advertising.
What we do NOT do
We do not collect your name or email address.
We do not use advertising identifiers (IDFA/AAID).
We do not use third-party advertising or ad-tracking SDKs.
We do not sell or share your data for marketing purposes.
We do not require an account to use the App.

Google's and RevenueCat's own privacy policies govern how they handle data once received:

Your choices
Because your profile answers and scan history are stored locally on your device, deleting the app deletes this data. To cancel or manage your subscription, use the App Store's subscription management (or the in-app "Manage Subscription" option). Deleting the app does not automatically cancel an active subscription — cancel it separately through the App Store.
Children's privacy
ChiScan is not directed at children under 13, and we do not knowingly collect information from anyone under that age.
Changes to this policy
We may update this policy from time to time. Continued use of the App after a change means you accept the update.
