About this reference
Each entry explains what a cookie is for, who sets it, how long it usually lasts and what its value looks like, checked against the vendor's own documentation. Where TagPipes has seen the cookie in the wild, the entry also shows how often.
Those figures come from 41,162 public websites TagPipes scanned between August 11, 2026 and September 13, 2026, loading up to three pages per site in a real browser. Websites of TagPipes customers are excluded, no individual site is named, and cookie values are never read or stored.
Know every cookie your own site sets
TagPipes Pulse identifies the cookies dropped on your site and flags unclassified or miscategorized ones. Shield builds your cookie declaration from a real scan rather than a questionnaire.
TagPipes monitors, configures and reports. It does not determine legal compliance and does not provide legal advice. Output is informational and reflects observed state at the time of observation. Rawsoft's expertise is technology, not law; please confirm any regulatory interpretation with your own counsel.
