In short: Tern has no accounts. We don’t ask for your name, email or ID, we don’t use analytics or tracking cookies, and we don’t sell data. To run a swap we process your wallet addresses and the details of that swap, which are public on the blockchain anyway. A few things, such as your last connected wallet, are kept only in your own browser.

1. Who we are

This Privacy Policy explains how Unit Labs (unitlabs.xyz) (“we”, “us”, “our”) handles information when you use the website at ternswap.xyz, the app at app.ternswap.xyz and the Tern API (together, the “Interface”). Unit Labs is responsible for the personal data described here. It is part of our Terms of Use.

2. What we process

Swap and wallet information

When you connect a wallet, ask for a quote or make a swap, the Interface sends the Tern API:

  • the wallet address you send from, and the address you receive at or are refunded to;
  • the assets, chains and amounts of the swap; and
  • the hashes of the transactions that fund and complete it.

The API stores quotes and their progress so it can run your swap, show you its status, and power the public explorer. These records are tied to wallet addresses, not to your name. Wallet addresses and transactions are recorded permanently on public blockchains and can be seen by anyone.

Technical information

Like any website, our servers and our infrastructure providers, such as Cloudflare, receive your IP address and basic request details (for example, your browser type and the time of the request) when you use the Interface. We use them to deliver the Interface, keep it secure and apply rate limits that prevent abuse. We do not store IP addresses in our databases. Rate-limit counters are kept in memory only briefly. Our infrastructure providers may log requests for security under their own policies.

Messages you send us

If you email us, we receive your email address and whatever you choose to include, and we use them to reply.

What we don’t collect

We don’t ask for or collect your name, email address, phone number, government ID or payment card details to use the Interface. We don’t use analytics tools, advertising trackers or tracking cookies, and we don’t build profiles of you.

3. Stored only in your browser

The app keeps some information in your browser’s local storage so it can work without an account. It stays on your device, and we can’t see it:

  • the name of the wallet you last connected, to reconnect it next time;
  • addresses you recently entered, so you can pick them again;
  • your token balances, cached to load faster; and
  • for swaps between blockchains, the secret that completes your swap. It is removed when the swap is finished.

You can clear this at any time in your browser’s settings. Clearing it while a swap between blockchains is in progress can stop that swap from completing. Your funds then return to your refund address after the swap expires.

4. Who receives information

We don’t sell or rent personal data. Information is shared only as needed to run the Interface:

  • Solvers and exchange aggregators. To quote and complete a swap, its details, including the sending and receiving addresses, are shared with independent solvers and decentralized exchange aggregators, such as KyberSwap and AVNU.
  • Blockchains. Your swap’s transactions are broadcast to public blockchains and are visible to everyone.
  • Services your browser contacts directly. The app reads balances and transaction status from public blockchain nodes, which receive your wallet address. It also loads token prices from DefiLlama, token lists from KyberSwap and AVNU, and token logos from sources such as CoinGecko. These services receive your IP address and see what your browser requests, under their own privacy policies.
  • Infrastructure providers. Our hosting and network providers, such as Cloudflare, process requests on our behalf.
  • When the law requires it. We may disclose information if required by law, regulation or valid legal process, or to protect the rights, property or safety of our users, Unit Labs or others.
  • Business transfers. If Unit Labs is involved in a merger, acquisition or sale of assets, information may be transferred as part of that transaction.

5. Why we use it

We use the information above to:

  • quote, run and track your swaps, and show their status in the app and the explorer;
  • keep the Interface secure, prevent abuse and enforce rate limits;
  • meet our legal obligations, including sanctions compliance; and
  • understand and fix problems, so the Interface stays reliable.

Where data protection laws require a legal basis, we rely on what is necessary to provide the Interface you asked to use, on our legitimate interests in keeping it secure and working, and on our legal obligations.

6. How long we keep it

We keep swap records for as long as we need them to run the Interface, keep an accurate history of swaps, and meet our legal, accounting and security obligations. We keep emails for as long as needed to deal with your message. Information recorded on public blockchains can’t be changed or deleted by anyone, including us.

7. Your rights

Depending on where you live, including under Singapore’s Personal Data Protection Act 2012 and, where it applies, the EU and UK General Data Protection Regulation, you may have the right to:

  • ask what personal data we hold about you and get a copy;
  • ask us to correct it;
  • ask us to delete it, or to limit or stop using it; and
  • withdraw consent where we rely on it.

To make a request, email [email protected]. Because the Interface has no accounts, we may ask you to show that you control the wallet address your request is about. Some data, such as records on public blockchains or records we must keep by law, can’t be deleted. You can also complain to your data protection authority; in Singapore, that is the Personal Data Protection Commission.

8. International transfers

Our servers and service providers may be located in countries other than yours, including outside Singapore. Where we transfer personal data internationally, we take steps to make sure it is protected to the standard that applicable law requires.

9. Security

We use reasonable technical and organizational measures to protect the information we hold, including encrypted connections. No system is completely secure, though. Keeping your wallet, keys and device safe is up to you.

10. Children

The Interface is not for anyone under 18, and we don’t knowingly collect personal data from children.

11. Changes to this policy

We may update this Privacy Policy from time to time. We’ll change the date at the top when we do, and if a change is significant we’ll make reasonable efforts to point it out in the Interface.
