PRIVACY POLICY
1 · Scope
This policy describes how the off-chain components of Liqua (this website, the relayer at relayer/server.js) handle data. It does not apply to the blockchain itself, which is operated by independent nodes outside our control.
2 · What we collect (off-chain)
| data | why | where it lives | retention |
|---|---|---|---|
| Wallet address | identify maker on an order · receiver on a chat message | in-memory + shared/book.kernel.json on the relayer host | until the order expires, the chat message ages out of the 200-message ring, or the host is restarted |
| Signed order data | serve the orderbook to other users | in-memory + kernel JSON | until expiry or fill |
| Signed chat messages | display in the chat panel | in-memory ring buffer (200 cap) + kernel JSON | last 200 messages |
| Request IP address | basic rate-limiting / abuse prevention | web server logs (rotated) | ~7 days |
| Error reports (if Sentry is enabled) | debugging | Sentry servers | per Sentry retention (typically 30–90 days) |
3 · What we don't collect
- No cookies. We don't set tracking cookies. Your browser may store wallet state (e.g. MetaMask's permissions) but that's the wallet, not us.
- No analytics scripts. No Google Analytics, no Mixpanel, no Segment, no Facebook pixel, no Hotjar.
- No PII. We don't ask for name, email, phone, address, ID, or anything else identifying. We can't, because we don't have accounts.
- No fingerprinting. No canvas fingerprinting, no font enumeration, no browser fingerprinting.
- No cross-site tracking. We don't share data with ad networks.
4 · What's on-chain (and we have no control over)
Anything you do on the blockchain — placing orders, signing transactions, transferring tokens, voting on governance proposals — is permanently public. Anyone can see it on a block explorer. We did not put it there; the blockchain did. Once on-chain, it cannot be deleted.
If you require privacy for your trading activity, use a fresh wallet per session, or use a privacy-preserving mixer or zkRollup. Liqua does not offer this; it's a transparent-by-design DEX.
5 · Embedded third-party scripts
Some pages load resources from third parties to function:
- ethers.js via cdnjs.com — Ethereum signing + RPC client
- TradingView widget on the main trading page — real-time market chart (loads from
s3.tradingview.com) - Binance public WebSocket feed (relayer-side, not your browser) — live ETH/USDT depth
These services have their own privacy policies and may log your IP address when their resources load. We do not control their data handling.
6 · Sharing
We do not sell, rent, trade, or otherwise distribute the data we hold. We may disclose data if required by lawful subpoena or court order in a jurisdiction where we operate.
7 · Your rights
Because we hold very little data, most data-access requests resolve quickly:
- Access: we'll tell you what we have on you (typically: your wallet address showing up in the recent book / chat / trades).
- Deletion: we'll remove your wallet address from off-chain stores on request. We cannot remove on-chain data.
- Correction: rarely relevant — what we hold is signed by you, so the chain of evidence is what it is.
Send requests to [privacy@liqua.app · TBD]. We aim to respond within 30 days.
8 · Security
The off-chain relayer is a standard Node.js application running behind HTTPS (in production). Operational security depends on the deployment — whoever hosts is responsible for keeping the kernel file (shared/book.kernel.json) and any keys (MIRROR_KEY) safe.
We use commercially reasonable measures to protect the relayer's host environment. We cannot guarantee absolute security; no internet-connected system is fully immune to compromise.
9 · Children
Liqua is not directed at children under 13 (or the applicable minimum age in your jurisdiction). We do not knowingly collect data from minors.
10 · International users
Liqua's relayer may be hosted in the United States or other jurisdictions. By using the service from outside, you consent to data transfer to and processing in the host country.
11 · Changes to this policy
We may update this policy from time to time. The "last updated" date at the top reflects the most recent change. Substantial changes will be announced via the project's official channels.
