Zero-Data Architecture.
Last updated: September 2026 • Version 1.2
- We do not collect or sell personal data. No names, email addresses, phone numbers, or government IDs are ever requested or stored on our servers.
- Blockchain data is public by design. When you connect your wallet and execute a transaction, your wallet address and swap parameters are recorded on the public blockchain ledger.
- Local storage only. Preferences such as slippage tolerance, favorited tokens, and dark theme state are saved locally in your browser’s localStorage.
1. Information We Do Not Collect
probl.fun is built on non-custodial Web3 principles. We do not maintain user account databases, do not use invasive tracking pixels, and do not profile individual users. There are no registration forms, KYC verification processes, or private financial records stored by this frontend.
2. Wallet Connections & RPC Interactions
When you connect a Web3 wallet, the application reads your publicly available cryptographic account address via standard browser APIs (e.g., EIP-1193 / EIP-6963). This address is used solely to query on-chain balances and request signatures for transactions you explicitly authorize.
3. Public Ledger Transparency
Transactions submitted via probl.fun are broadcast directly to peer-to-peer blockchain validator nodes (Arc Network, Robinhood Chain, Solana, Base, BNB Chain). Once confirmed, transaction details (including sender address, amounts, and timestamps) are permanent and publicly accessible on block explorers.
4. Browser Local Storage
The interface uses standard browser localStorage to remember your selected slippage presets, active network choice, and token watchlist. This information never leaves your device and can be cleared at any time via your browser settings.
