Privacy policy

Last updated 2026-11-04 (UTC).

What we do not collect

No account, no email, no analytics, no advertising trackers, no fingerprinting. The website sets no cookies.

What stays in your browser

The preimages of the orders you commit and the keys of the deals you create are saved in your browser's local storage, so you can reveal and share them later. They never leave your device unless you choose reveal for me. The part of a deal link after # is not sent to the server by browsers.

What the server stores

If you choose reveal for me, the website stores your signed reveal message (your address, the batch, the order index and the order's preimage) in a private store, only until the operator key reveals the order on chain, and deletes it then or when the batch has passed. Our hosting provider keeps standard request logs (IP address, time, path) for a short period for security and operation.

What is public by nature

Wallet addresses, deposits, withdrawals, commitments, revealed orders, settlements and deals are transactions on a public blockchain. They are public, permanent and outside our control.

Your rights (GDPR)

For data held off chain (a stored reveal message, request logs), you can ask for access, correction or deletion, or object to processing, by sending a message to the project's X account. The legal basis for processing a reveal message is the performance of the service you asked for. You can also complain to your data protection authority. We cannot alter or delete data written to the blockchain.

Processors

Hosting and the private store run on Vercel. Chain reads go through the public Robinhood Chain RPC.
