Privacy & security

BiuBiu Tools is built so that the sensitive parts of your work never have to leave your device. This page explains the model so you can verify it for yourself.

Self-custody

You hold your keys. BiuBiu cannot move, freeze, recover, or refund your funds. The only on-chain actions that happen are the transactions you approve and sign with your own wallet.

What stays on your device

• Address lists, scan inputs, and reports (e.g. in Balance Radar) are processed in your browser and not uploaded.
• Generated keys and encryption happen locally. Air-gapped flows are designed to work fully offline.
• Your passkey lives in your device’s secure hardware. The private key never leaves it and BiuBiu never sees it.

What goes on-chain

Only the transactions you approve. Before you sign, the tool shows the action in human-readable terms — recipient, amount, network, and fee.

No blind signing

Transactions are decoded and presented in plain language. Unknown or unusual calls are flagged rather than hidden behind raw hex.

The risk you own

Verify it yourself

The toolkit is open source on GitHub. If a claim on this page matters to you, you can read the code that backs it.
