Privacy Policy

Qern is designed to collect as little data as possible. We do not ask for your name or identity documents.

What we process

• Public wallet addresses and transaction hashes you submit, to show route status, history and points.
• Quote requests (tokens, chains, amounts), sent to routing providers to obtain quotes.
• IP addresses, used briefly for rate limiting and abuse prevention.
• Usage analytics: pages visited, referrer, approximate location, device and browser information, collected with Google Analytics to understand how the Interface is used. Wallet addresses are not sent to Google Analytics.
• Error reports (without request bodies or cookies), to fix bugs.
• Your email address, only if you join a waitlist, to send launch news and updates.

Third parties

Quote and status requests are forwarded to our liquidity and routing providers and to public blockchain RPC nodes, which process them under their own policies. Wallet connections are handled by your wallet provider and WalletConnect. Usage analytics are processed by Google (Google Analytics), which sets analytics cookies; see Google's privacy policy at policies.google.com/privacy. You can block them with your browser's cookie settings or the Google Analytics opt-out browser add-on.

Public blockchains

Transactions you sign are recorded on public blockchains and cannot be deleted by anyone, including Qern.

Local storage

The Interface stores preferences, such as your risk acknowledgement and referral code, in your browser. Google Analytics stores its own cookies (such as _ga) to distinguish visits.
