Privacy
Nothing. Specifically, and each of these is verifiable in the published source:
localStorage, no sessionStorage.Pages showing live chain data ask mainnet-node.decentralchain.io for the current block. Your browser makes that request directly — there is no proxy of ours in the middle, which is the same property that lets any script read the chain without a key.
That request carries what every HTTP request carries: your IP address and user agent. The node needs no account and issues no identifier, so nothing links one request to another beyond what any web server sees. If you would rather it did not happen, the pages still render without it and say the node was unreachable.
Links point to GitHub, npm, the ecosystem applications, and community platforms. Once you follow one you are on someone else's site under their policy, not this one. We receive nothing back from those visits.
Worth saying plainly, because it is the more consequential fact. DecentralChain is a public ledger. Every transaction, balance, address and lease is readable by anyone forever, by design — that is the point of the thing. This page describes the website; it does not and cannot make on-chain activity private.
This site is operated by DecentralExchange, Cédula Jurídica 3-102-956858, of Jacó, Garabito, Costa Rica, which is the controller for anything described here. Questions go to info@decentralchain.io.
Because the site holds no personal data, there is no record for us to export, correct, or delete on request — the honest answer to such a request is that nothing exists to act on.
