xChange Privacy Policy

Last updated: November 2, 2026

xChange ("we", "the app") is a non-custodial interface for swapping and bridging crypto assets. This policy explains what data the app handles.

1. We do not hold your funds or keys

xChange never asks for, receives or stores your private keys or seed phrase. You connect your own wallet app (for example through WalletConnect), and every transaction is signed in your wallet.

2. Data we do not collect

We do not require an account. We do not collect your name, email, phone number, contacts, precise location, photos or device identifiers, and we do not use advertising IDs.

3. Data processed by third-party services

To show quotes and run transactions, the app sends the following to service providers:

• LI.FI (routing and quotes): public wallet address, tokens, chains and amounts you choose. See LI.FI's privacy policy.
• WalletConnect / Reown (wallet connection): connection metadata needed to link your wallet. See Reown's privacy policy.
• Blockchain networks: transactions you sign are public and permanent on the relevant blockchain.

Wallet addresses may be screened against public sanctions lists to block prohibited transactions.

4. Website only: analytics, error reports and regional access

These apply to the website (xchange.noonbarbari.xyz), not to the Android app:

• Analytics: we use a self-hosted, cookieless instance of Plausible Analytics to count page views and anonymous usage events (for example "quote shown" or "swap completed", with chains, token pair and a rough size range). It does not use cookies, does not store IP addresses and cannot identify you.
• Error reports: if the website crashes, a technical error report (browser type, page and error message) may be sent to our self-hosted error tracker. Wallet addresses are removed before sending.
• Regional access: to comply with sanctions and local licensing rules, our server checks which country your IP address belongs to and blocks access from restricted regions. The IP address is only used for this check and is not stored with any other data.

5. Data stored on your device

The app stores settings, recent tokens and transaction history locally on your device. You can delete it by clearing the app's storage or uninstalling the app.

6. Data sharing and sale

We do not sell personal data. Data is shared only with the providers listed above, as needed to provide the service, or when required by law.

7. Security

All connections to our providers use encrypted HTTPS/WSS.

8. Children

The app is not intended for anyone under 18.

9. Changes

We may update this policy. The date above shows the latest version.
