This page lists every cookie and every browser storage item Sentinel sets, what each one does, and how long it stays.
Under the GDPR and § 25 TTDSG, cookies that are strictly necessary for a service you asked for need no consent. Sentinel sets only those. We still show a notice and remember that you saw it.
