What personal data does a no-registration swap site collect from my browser

05 September 2026

A no-registration swap site collects only the technical data your browser automatically sends during a normal visit: your IP address, browser type, operating system, referring page, and the pages you load. No personal data such as your name, email, or wallet address is stored by the site, because you never provide it.

The reason is straightforward. Registration is the mechanism that ties a specific identity to a set of actions. Without registration, the site has no account to attach data to. It cannot ask for a name, an email, or a phone number because there is no user profile to put them in. The information it receives is limited to what any web server receives when you load any page: connection metadata and request headers.

Your IP address is the most consequential piece. It is a network-level identifier. The site sees the IP address your internet service provider assigned to your router. That address can be linked to a geographic region (often a city), but not to your name unless a third party - your ISP or a law enforcement body - matches that IP to a subscriber. The site itself does not make that match. It logs the IP for basic operational reasons: preventing denial-of-service attacks, rate limiting, and debugging errors. Some logs are retained for a period, usually days to weeks, then deleted.

Your browser type and operating system are sent in the User-Agent header. This tells the site what software you are using so it can serve the correct page layout. It is not personal data in any meaningful sense. The referring page shows which link brought you to the site. That is useful for analytics but reveals nothing about you.

The site may also use a temporary session cookie. This cookie does not store personal information. It is a random string that lets the server keep track of your current swap transaction across page loads. Without it, a swap would break if you refreshed the page. The cookie expires when you close the browser or after a short time. It is not used for tracking across visits.

No wallet address is collected. The swap process works by you sending assets to a generated deposit address. The site sees that address as part of the transaction on the blockchain, but it does not associate it with your browser session unless you voluntarily provide it. The site does not ask for your wallet address to connect or to receive funds. You provide only the destination address for the output side of the swap, which is a public blockchain address anyway.

No registration means no password, no security questions, no backup phrase. The site has nothing to store. That is the point of the model. If you are interested in understanding the broader implications of this approach, the hub page "Swapping crypto without an account" covers the trade-offs in detail.

The key takeaway is that the data collected is the minimum necessary for the web to function. It is the same data any website collects when you visit it. The difference is that a registration-based site adds layers of personal data on top of that baseline. This site does not. The honesty of the answer is that some data is collected - it is impossible to serve a web page without it - but no personal data is collected because there is no mechanism to collect it. The site is designed to be a transient interface, not a database of identities.
