Privacy policy

Swaplume is built to need as little about you as possible: no account, no cookies, no analytics. This page covers swaplume.com and the Swaplume API (api.swaplume.com), including its MCP server.

When you look at offers

We send the coins, networks and amount you entered to each exchange we compare. Like any website, our API sees your IP address. We use it to apply rate limits, in memory, and record it only with a swap at an exchange that requires it (below).

When you create a swap

We send the exchange you chose what it needs to create the swap: the coins and the amount, your receiving address, and the memo, refund address or email if you gave them. ChangeNOW and SideShift also receive your IP address from us, as they would if you used their sites directly, for their fraud and country checks. From then on, the exchange handles this data under its own privacy policy. FixedFloat requires its partners to keep each customer's IP address and browser languages for at least a year. For your swaps with FixedFloat, we keep both with the swap for a year (a week if you never send the deposit), then delete them, and share them only with FixedFloat, if it asks about that swap.

What we keep

For each swap we keep its ID, the exchange and that exchange's ID for the swap, the coins and amounts, the exchange's deposit address, the swap's status and times, and the user agent of the browser or app that created it (it tells us whether swaps come from the site, the API or AI agents). We don't keep your receiving or refund address or your email, and keep your IP address only as described above. If you never send the deposit, we delete the swap a week after you created it, with everything we kept about it. We keep the records of the other swaps for support and accounting.

In your browser

The site saves your recent swaps in your browser's local storage so you can find them again. That list never leaves your device, and clearing the site's data removes it. The site sets no cookies.

Services we use

• Cloudflare delivers the site and the API and protects them from attacks, which means it processes IP addresses.
• Google Cloud hosts the API's server.
• The API reference page (api.swaplume.com/docs) loads its viewer from jsDelivr, a public code network.
• The exchanges we compare, ChangeNOW, SimpleSwap, FixedFloat, Alfacash, SideShift, InstaSwap, CoinCraddle, CCE Cash and Changelly, each under its own privacy policy.

Questions and requests

Email contact@swaplume.com about your data. For a swap, include its ID: it's in the swap's link and on its page.
