Your calculation
Your birth date is submitted through a form for calculation. We do not add it to new URLs, request logs or a results database. The form is not stored in localStorage. Result pages are not indexed or cached.
Request logging
To operate the service and understand automated traffic, we store the time, method, sanitized path, response status, bounded User-Agent and request classification. IP addresses are converted to HMAC tokens by default. Request bodies, cookies, credentials and raw query strings or Referer are not stored.
Retention and access
Retention is configured by the service operator. Reports are available only to the operator. Bot detection is heuristic: a browser name does not prove a human request. Classification does not automatically block traffic.
- Event retention, days: 90
- Aggregate retention, days: 365
- Raw IP storage is disabled.
