Reading the site.

We do not run third-party advertising scripts, heatmaps, session recordings or visitor-tracking analytics on this publication. Library search and filters run in your browser; search terms are not submitted to our server. We do not set analytics cookies or save reading histories in browser storage.

Cloudflare hosts the site and processes connection information needed to deliver and secure it, such as IP addresses and request metadata. This is separate from the application’s own tracking, which is disabled. See Cloudflare’s privacy policy for its practices.

Contacting the publisher.

If you email us, your address and message are used to handle your request. The contact address is forwarded through Porkbun and SimpleLogin to the publisher’s mailbox. Do not send medical records or sensitive personal health details. This is not a clinical service.

Earlier expressions of interest.

The former concept page collected email addresses, stated product interest and email permission. New reservations are now paused. Existing records remain private and are not automatically converted into research-newsletter subscriptions.

The existing retention schedule deletes those records after 12 months. Associated campaign context is removed with the record; earlier aggregate measurement counts are retained for up to 90 days. The earlier rate-limiting system used temporary keyed network identifiers, with a two-hour expiry and daily cleanup.

To request access, removal or withdrawal of earlier email permission, contact privacy@puss-c.com. We may need to confirm that you control the address concerned.

External links and changes.

Original papers and other linked websites follow their own privacy practices. We use a no-referrer policy on outgoing requests. Material changes to this page will be reflected in its effective date.
