1. Current scope
The site no longer creates signup, login or Research-session cookies. Browser display preferences and optional analytics remain separate. Closing features does not automatically remove historical browser data or server records.
2. Analytics and withdrawal
Analytics is off until explicitly allowed. Choice storage lasts 180 days; Analytics cookies last at most 60 days without visit-based renewal. Privacy and analytics settings allows refusal or withdrawal without losing access to the site.

4. Historical items and removal
Earlier next-auth authentication cookies and seonik research/eligibility browser records may remain. They no longer authorize member access. Visiting an old account or auth endpoint attempts to expire recognized authentication cookies; this is not server-account or backup deletion. Browser site-data settings can remove old browser records and preferences. Historical server-data requests can be sent without login to seonik.official@gmail.com. See the Privacy Policy.
