# Ethereum Beat — PRIVACY

> What Ethereum Beat collects: essentially nothing.

- **No accounts, no login, no personal data.** There is nothing to sign up for and no profile to build.
- **No tracking cookies.** The only browser storage is your theme choice in `localStorage`, read client-side only.
- **Analytics are cookieless and aggregate.** When enabled, Cloudflare Web Analytics counts page views without cookies, fingerprinting, or cross-site identifiers — and it is env-gated, so a fork with no token ships no analytics at all.
- **No third-party ad networks or trackers.**
- **Third-party data.** The live layer fetches public Ethereum RPC and Beacon endpoints (PublicNode, dRPC, 1RPC) directly from your browser; those hosts see the request as any website would. Ethereum Beat shares nothing with them.
- **Open source and self-hostable.** The code is MIT; run your own copy if you prefer.

Questions: beat@ethereumbeat.org. This is the "P" in CROPS, applied to the site itself.
