Privacy
Sailswap has no accounts and never holds your funds. It does keep a record of how the interface is used, and of swaps that go through it, so that failures get found and fixed and new features get built on what actually works.

Usage logging
Activity on the interface is logged — which pages get opened, what gets clicked, recordings of how people move through it, and an automatic report when something breaks. It exists to catch bugs, see where swaps fail, and decide what to build next. Logging runs on every visit and cannot be switched off from inside the site; browser privacy settings, tracker blockers and private browsing all work here. Recordings are deleted automatically after 30 days.
Swaps are read
When a swap confirms or fails, the trade and the wallet that made it are recorded, so we can see how routing performs in practice, fix the paths that fail and build new features on top of what works. The trade itself is public on-chain either way.
Your wallet address
Connecting a wallet gives the interface your public address. It is used to read balances, check token allowances and build the transaction you sign. It is not attached to the usage logging above.
Never your keys
Sailswap is non-custodial. It holds no funds, has no backend wallet, and never asks for a private key or a seed phrase. Every swap is a transaction you approve in your own wallet — anything claiming to be this site and asking for a seed phrase is not this site.
What your browser stores
Your swap history is kept in local storage on your device, keyed by wallet address, and is never uploaded — which is why it is tied to this browser and disappears when you clear site data. Recently used and imported tokens are stored the same way, alongside the cookies the logging tools use to tell one visit from the next.
Who else is involved
Quoting and swapping means talking to other services, each under its own terms: your wallet provider and the network that connects it, public RPC providers, a price source for the USD figures, and the blockchain itself, where every transaction is permanently public. The logging, hosting and contact relay are run by third-party service providers on our behalf. Nothing is sold, and nothing is passed to advertising networks.
The contact form
The name, email address and message you submit are passed to the site operator so the message can be read and answered — nothing more. No mailing list, no onward sharing.
Your rights
If you are in the EU, EEA or UK you may ask what is held about you, ask for it to be deleted, or object to it being kept — through the contact form. One limit worth stating plainly: nothing on a public blockchain can be deleted, by us or by anyone else.
