Privacy

Cerulean is not a privacy product. If privacy is your top priority, use DuckDuckGo or Kagi.

What Cerulean does

• No user accounts. No tracking cookies.
• No analytics on the frontend.
• Server-side request logs (standard Vercel logs - IP, user-agent, timing). Used for debugging, not analysis.
• Search queries are forwarded to upstream providers (Brave, Serper, DuckDuckGo). Each has its own privacy policy. Brave and DuckDuckGo claim not to track; Serper is a commercial API used as fallback and logs queries on its side.
• LocalStorage remembers your dark-mode preference. That is it.

Cerulean uses upstream APIs because crawling the web is expensive. If Serper's logging becomes a meaningful issue, the upstream stack can be changed.

The site is hosted on Vercel, which has its own privacy policy. The code is open source - you can self-host if you would rather not trust this deployment.
