What we collect, and why

Visit statistics

• When you open a page, a cookie named ne4-anon-visit stores a random number (not linked to you) for 30 days, so we can count visitors instead of page loads.
• We record the day, the page layout you saw and your country. The country is worked out from your internet address at that moment (or from our hosting provider's country signal); the address itself is not stored in these statistics.
• Daily statistics are kept for about 30 days. Search engines and automated tools are not counted.
• Like almost every website, our hosting provider keeps standard server logs (internet address, time, page requested) for security and troubleshooting, under its own retention rules.

Our own news stories

To count story reads and button clicks without retaining an internet address, we use a random, signed browser cookie (ne-news-anon). Daily deduplication keys are removed after a short period; the story totals remain.

Lookups on the Explorer

When you search an address, transaction or block, our server asks public blockchain nodes (and, for Ethereum address history, Etherscan) for the answer. Your internet address is not sent to them; they only see our server. To limit abuse we count requests per anonymous browser token when available, as well as globally. We do not store internet-address-derived lookup keys. Results are cached for everyone for a short time.

The network charts (fees, transactions and speed over 90 days) are built from public network figures our server reads every few minutes. They contain nothing about visitors.

News from other publishers

Headlines and short excerpts come from the publishers' public RSS feeds. Their pictures are fetched and resized by our server, so your browser does not contact the publishers until you open a story. When you do, you are on their site and their privacy policy applies.

Earlier notification subscriptions

Older versions offered News emails, push notifications and address alerts. These features have been discontinued. Existing server subscription records, if any, are not used for new sends and should be deleted by the site operator after reviewing any retention obligations.

Stored only in your browser

• ne4-selected-network cookie and local storage: the network you picked, so the page opens on it next time (1 year).
• News interactions use a separate anonymous, signed browser token (ne-news-guard) for request limiting, without storing your internet address.
• Local storage: your recent and saved Explorer searches, the News stories you save for later, and your light or dark theme. Clear them any time from the Explorer search box, the Saved list or your browser settings.

What we do not do

• No advertising or tracking scripts, and no third-party analytics.
• We do not sell or share data. Prices and network data are fetched by our server, not by your browser.
• Nothing on this site is investment advice.

Your choices

You can block or delete cookies in your browser; the Explorer and News keep working without them. The public pages do not ask for an email address. If you used a previous version with email subscriptions, contact the site owner to request deletion of those legacy records.
