This notice covers the website at test.network and the public London testnet node it proxies to. It is written to be read, not to be scrolled past: the short version is that there are no accounts, no sign-ups and no advertising, and the site keeps as little as it can while still running. The data controller is XE L1 Ltd. (UK company 17245674), 128 City Road, London, EC1V 2NX.
The web server records each request's IP address, user agent, the URL requested, the time and the response status. These logs are used to keep the site up, to debug it and to defend against abuse, and are rotated on a short schedule. They are not used to build profiles and are not shared, other than with the hosting provider on whose machines they sit.
Requests to /api on this site are forwarded to the London testnet node at ldn.test.network. The node applies per-IP rate limits, so it necessarily sees your IP address for as long as the limit window lasts. Requests you make directly to ldn.test.network go there without passing through this site at all.
Anything you write to the testnet — blocks, account addresses, balances, directory registrations, chat envelopes — is public by design: it is replicated to every node and shown in the explorer. Do not put personal data in a chat message or a block. The testnet may be wiped, but you should treat anything written to it as permanent and public.
The question box on this site is Edge Assist, a third-party service loaded from assist.edge.network. Questions you type into it are sent to Edge Network to be answered from this site's public content and are subject to their privacy policy. Nothing else on the site loads from a third party: fonts are served from test.network, and there are no analytics scripts, tracking pixels or advertising tags.
Under UK GDPR you can ask what we hold about you, ask for it to be corrected or deleted, and complain to the Information Commissioner's Office. Because the site holds only short-lived server logs keyed by IP address, most requests will find nothing to return; write to hello@xe.network or to the registered office and we will check. This notice is versioned with the site's source code, so its history is public in the repository; material changes are noted in the commit that makes them.
