Privacy

Last updated 2026-09-15.

This site is built to know as little about you as possible. There is no account to create, so most of a normal privacy policy simply does not apply here. The one thing you can sign up for is the mailing list, and it is optional.

What we do not do

• No accounts, no passwords.
• No cookies. The one thing we ever write in your browser is a referral code, and only if you arrived through someone's referral link (below).
• No analytics, no trackers, no advertising, no fingerprinting.
• No custody: your keys and seed phrase never touch this site, and nothing here can read them.
• We do not sell, rent, or share data about you. We barely have any.

What leaves your browser when you use the swap

The page is a static file; the swap works by your own browser talking directly to a few public services. Each one sees your IP address, the way every website you visit does, plus exactly this:

• DotSwap (api.dotswap.app), the venue that prices and executes swaps: the amounts you ask about, the pair's price history and recent swaps the site shows (no address of yours rides with those reads), and, once you connect a wallet and build a swap, your wallet addresses and public keys. When you submit, it receives your signed transaction.
• mempool.space, public Bitcoin data: fee rates and blocks, your addresses when checking a balance, and your transaction id while a swap is confirming.
• ordinals.com, a public Runes indexer: the coins at your connected address, which we look up to show your $DOG balance, and the specific coins your transaction touches, which we look up to verify what you are signing.

Each of those services has its own operator and its own privacy practices; what they log is theirs, not ours. The web host serving this page keeps standard access logs, the same as any static site.

The chain is public

A submitted swap is a real Bitcoin transaction: public, permanent, and readable by anyone forever. That is a property of Bitcoin, not a choice of ours, and no privacy policy can undo it. Assume everything on chain is visible.

If you join the mailing list

Signing up sends your address to our own server, which mails you one confirmation link. Nothing is subscribed until you click it. We keep: the address, the times you signed up, confirmed and left, a keyed hash of your IP address at signup, and your browser family (Chrome, Safari, Firefox, Edge, or other, and mobile or desktop). The hash cannot be turned back into your address; it and the browser family exist only to stop abuse of the signup form, and they are the only such signals anywhere on this site.

Every mail we send carries a one-click link that removes you, and the standard unsubscribe header your mail client can act on. Mail is delivered by our provider, Migadu. We never share, sell, or rent the list, and it contains nothing but what is listed here. To have your record erased outright, write to [email protected] from the address in question.

If you follow a referral link

A referral link looks like dogswap.io/?r=CODE. When you open one, your browser keeps that code, in its own storage on this site only, for 30 days or until you sign in with a wallet, whichever comes first. It is not a cookie, it is not sent anywhere until you sign in, and it identifies the link, not you. At sign-in the code goes to our server once, so the wallet that shared the link can be recognised for it. Clear your browser's site data to remove it early.

If you email us

Writing to [email protected] shares your address and message with us, handled by our mail provider, Migadu. We use it to answer you and for nothing else.

If any of this changes

Today the mailing list and wallet sign-in are the only places we keep anything about you, the keyed IP hash and browser family on signups and sign-ins are the only abuse-prevention signals we hold, and the referral code above is the only thing we ever write in your browser. There are still no analytics and no identifiers anywhere else. If that ever changes, this page changes first, with a new date, before the change goes live. Questions belong at [email protected].
