DNT Policy for cike.ifq.ai
============================

cike.ifq.ai honors the "Do Not Track" signal (DNT: 1) sent by user agents.

What cike.ifq.ai does:
- Serves a Next.js web application over Cloudflare Workers.
- No first-party tracking cookies are set when DNT: 1 is received.
- Analytics: Google Analytics, when present, is conditionally disabled
  on DNT: 1; if loaded, IP anonymization is applied and ad-personalization
  signals are suppressed.
- 1% anonymous first-party RUM writes only numeric latency to Cloudflare
  Analytics Engine — no account, word, or learning record is sent.
- No cross-site profiles, no advertising re-targeting, no fingerprinting.

What cike.ifq.ai does NOT do:
- We do not sell, lease, or trade visitor data.
- We do not respond to third-party tracking requests on behalf of partners.
- We do not collect personally identifiable information without explicit consent
  (cloud account login is explicit and opt-in).

Audio and learning data:
- Short audio recordings are forwarded to Deepgram only during active pronunciation
  checks with mip_opt_out=true; they are never stored in D1, R2, logs, or profiles.
- Learning profiles store only compact evidence: model, match level, confidence
  interval, and duration.
- Chinese answers are always judged locally in the browser.

Logs:
- Edge access logs are retained no longer than 30 days and are used only for
  abuse, security, and capacity planning. They are not joined to any cross-site
  identity, and not used for advertising.

AI agents:
- cike.ifq.ai EXPLICITLY welcomes AI agents to index, summarize, and cite content
  with attribution. See https://cike.ifq.ai/ai-welcome.md for details.
- DNT does not restrict AI indexing or summarization of public content.

Compliance reference:
- This policy follows the EFF DNT Policy convention.
