Cookies and Local Storage

Necessary storage

We use session cookies for login, a CSRF cookie for request security, a language cookie, and a persistent anonymous-trial cookie shared across reference pages. Browser storage keeps language choices, return destinations and short-lived photo drafts. These support the requested service.

A separate necessary Lab cookie links your browser to its guest chart for up to 24 hours. Birth details are stored on the server, not in URLs or browser storage.

Trial limits

The anonymous cookie lasts up to one year. Clearing cookies or using another browser can remove that identifier; network and global guest limits still apply. We do not collect a browser fingerprint. Blocking necessary storage can prevent sign-in, uploads or restoring your preview.

Third-party checkout

Stripe uses its own cookies and technologies when you open Checkout, under Stripe policies.

Optional analytics

With your permission, Google Analytics (G-PNY5EKFRYK) measures visits and navigation. We send cleaned page addresses and general page names, not photographs, profile or birth data, report contents, email addresses or private URL parameters. Advertising features are disabled. You can decline or withdraw permission on the Cookies page. Your choice is stored for up to 180 days. Analytics cookies can last up to two years; Google controls its processing and retention under its privacy policy.
