When you visit
Ordinary site operations use limited server-side metadata.
Ada Ecosystem may keep a short rolling window of ordinary request and connection metadata for the public site, along with longer-lived daily aggregate counts. This helps operate the site, understand which pages are being requested, distinguish ordinary traffic from abuse, and troubleshoot service problems.
For ordinary visits, this operational data is kept intentionally narrow and is not meant to identify individual visitors. The public pages do not use client-side analytics code. Ada Ecosystem may use cookies and similar browser storage where needed to support sign-in, security, remember preferences, present or carry search results, and keep requested features working. The theme control stores your light, dark, or automatic preference in your browser’s local storage so your browser can remember your choice on that device.
