Birth calculations stay in your browser. Learn exactly which anonymous usage counters we collect.
Your birth record
The date, time, zone and longitude are calculated on your device. We do not send them to the analytics endpoint, an AI provider or an account database. A session-only draft may stay in your current browser tab so you can switch language or tools; the Clear birth details button removes it. Downloaded charts remain wherever you save them.
Anonymous usage counts
To learn whether the tool is useful, we store aggregate daily counts of page views, calculation starts/completions, guide clicks, downloads and interest-topic clicks. Records contain a public route, a broad traffic-source category and a fixed event label. We do not store your birth data, IP address, full referrer URL, email, a cross-site cookie or a stable visitor identifier in this database. These are event counts, not unique-person counts.
Your choice
Usage measurement stops when Global Privacy Control or Do Not Track is enabled, or when you turn it off using Usage statistics in the footer. An essential preference is stored locally to remember that choice. The optional interest buttons record a topic only when you click; no email signup or payment occurs.
Hosting and retention
The hosting provider necessarily processes network requests and may keep operational logs under its own policies. Our aggregate analytics database keeps a rolling 90-day window, pruned when new events arrive. This site has no third-party advertising or analytics scripts.
