Sending shares your message and recent turns with Article 11’s server, which asks S2_CASE, a Claude model run by Anthropic, to reply. Please don’t include private information.
What is sent and what is kept
Sent: this message and up to nine earlier turns from this page. Turns that got no reply are not sent again.
Where it goes: Article 11’s server, then Anthropic, whose Claude model writes the reply. Messages of 50 characters or more, and each reply, are also checked by an AI model hosted by Cloudflare.
What Article 11 keeps, according to the Worker snapshot captured on September 29, 2026: the time, the message length, a rough topic label, a shortened code made from your network address (it could be matched back to that address), and a counter tied to your address for up to two hours to limit sending. Records about each reply, such as its length, are also kept. If an automated check flags a message, a record of the check scores is added to Article 11’s chain.
That snapshot disables chat memory and conversation tracking for unauthenticated public requests; it does not establish live logging or provider retention. Anthropic handles the text under its own terms.
How long Article 11 keeps these records is not published. See the privacy page.
