Privacy Policy

Introduction

Kairo ("Kairo Guard," "we," "us," or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our non-custodial cryptocurrency wallet application and related services.

By using Kairo Guard, you agree to the collection and use of information in accordance with this policy.

Non-Custodial Architecture

Kairo Guard is a non-custodial wallet. This means:

• •Your private key share is generated locally on your device and never transmitted to our servers
• •We use 2PC-MPC (Two-Party Computation Multi-Party Computation) where no complete private key ever exists
• •We cannot access, recover, or control your cryptocurrency without your device's key share
• •Passkey credentials are stored in your device's secure enclave, not on our servers

Information We Collect

Information You Provide

• • Email address (if you sign up for notifications or beta access)
• • Public wallet addresses (visible on-chain by design)
• • Policy configurations (stored on-chain on Sui blockchain)
• • Recovery contact information (if you configure recovery options)

Information Collected Automatically

• • Device information (device type, operating system, browser type)
• • Usage analytics (features used, session duration, error logs)
• • IP address (for security and rate limiting purposes)
• • Transaction metadata (timing, gas usage—not transaction contents)

Information We Never Collect

• • Private keys or key shares
• • Passkey credentials or biometric data
• • Seed phrases (we don't use them)
• • The contents of your transactions

Data Security

• • Distributed network architecture with no single point of failure
• • Regular security audits and penetration testing
• • Access controls and authentication requirements

However, no method of transmission over the internet is 100% secure. While we strive to protect your data, we cannot guarantee absolute security.

• • Access the personal information we hold about you
• • Request correction of inaccurate information
