1. What we collect
My Chart Check collects only what's needed to compute your birth chart and deliver your reading: the birth date, time, and place you submit; the optional question and context you provide; and the cards/computations the system generates from these inputs. We do not require account creation, and we do not store your data after your reading unless you explicitly save it.
2. Cookies and local storage
We use a single browser cookie (pendingReading) to carry your chart data
from the preview page to the result page during checkout. We use localStorage
to remember your reveal preference and prevent duplicate ratings. No third-party tracking
cookies are set by our application.
3. AI processing
Your chart data and question are sent to Anthropic's Claude API to generate a personalized interpretation. Anthropic processes this data per their privacy policy. We do not retain prompts or responses beyond the active session.
4. Payments
Payments are processed by Whop, our Merchant of Record. Whop collects payment details directly — we never see your card number. See Whop's privacy policy.
5. Geocoding
When you enter a birthplace, we use OpenStreetMap's Nominatim service to convert it into coordinates. The place string is sent to Nominatim. No personal information is associated with the lookup.
