Privacy

ANTHILL is built to be anonymous.

• No email address or phone number is ever collected.
• Accounts are only a username and a 4-digit code. The code is stored as a one-way scrambled hash, never as typed.
• We do not store IP addresses with accounts or posts. Rate limits use short-lived counters in memory, and reports use a daily-changing one-way fingerprint.
• If you sign in, your reading progress, facts learned, quizzes, streak and questions are saved to your account so they follow you. Otherwise they stay in your browser only.
• Everything you ask is posted publicly on the Ask board, anonymously unless you choose to post with your username.
• No ads, no trackers, no third-party analytics. Images in stories load from public archives (Wikimedia, Library of Congress, Internet Archive, Europeana).
• Research and writing use AI models run by Anthropic through OpenRouter, and a local model. Questions you ask are sent to them to do the research.
