1. Introduction

SenseiFi ("SenseiFi," "we," "our," or "us") is committed to safeguarding the privacy, confidentiality, and integrity of user data. This Privacy Policy explains how we collect, use, disclose, and protect information in connection with our decentralized finance security platform, including our mobile applications, browser extensions, web dashboard, and related services (collectively, the "Services").

SenseiFi operates at the intersection of blockchain technology, artificial intelligence, and digital payments, offering tools such as wallet security monitoring, transaction analysis, threat detection, and crypto-based payment solutions. Given the nature of decentralized systems, we are deliberate in minimizing data collection while maintaining high standards of security and usability.

By accessing or using SenseiFi, you acknowledge that you have read and understood this Privacy Policy.

2. Information We Collect

We adopt a data-minimization approach. The categories of information we may collect include:

2.1 Information You Provide

• Account details (e.g., email address, username)
• Subscription and billing information
• Customer support communications

2.2 Wallet and Blockchain Data

• Public wallet addresses
• Transaction metadata (e.g., contract interactions, token approvals)
• On-chain activity necessary for risk analysis and security alerts

Important: SenseiFi does not collect or store private keys, seed phrases, or wallet credentials.

2.3 Automatically Collected Information

• Device and browser information
• IP address and approximate geolocation
• Usage analytics (features accessed, session duration)
• Log data (errors, system diagnostics)

2.4 AI and Security Analysis Data

To provide intelligent insights and protection:

• Smart contract interaction patterns
• Token behavior and risk signals
• Phishing URLs and suspicious domain interactions
• Transaction simulation inputs and outputs

2.5 Payment and Card Data (SenseiCard™)

Where applicable:

• Card issuance data (processed via third-party providers)
• Transaction records and spending analytics
• Fiat conversion metadata

Note: Sensitive payment data is handled by regulated third-party payment processors and is not stored directly by SenseiFi.

2.6 SenseiFi - Web3 Wallet Security & Airdrop Intelligence (SenseiGuard) browser extension

If you install our Chrome extension ("SenseiFi - Web3 Wallet Security & Airdrop Intelligence" / SenseiGuard), the following applies in addition to the categories above. We keep this list aligned with what the extension actually stores and sends.

Local storage on your device (via Chrome storage.local): user protection settings (thresholds, toggles), a list of recent security alerts, a cache of threat-intelligence data fetched from our servers, your wallet session / connected public address after you connect, a short queue of security-relevant events pending upload, and per-tab domain risk snapshots used to show warnings. We do not store private keys, seed phrases, or wallet secrets in the extension.

Network requests to our API (HTTPS): the extension may call our backend to (a) analyze a pending transaction or signing request, (b) check dApp/site context when connecting, (c) register your connected wallet address and chain when you choose to connect, (d) download a periodic threat feed (e.g. malicious contract/domain lists), and (e) send queued telemetry events (for example transaction evaluation outcomes, domain-risk detections, and sync heartbeats). Payloads are limited to what is needed for security analysis and service operation.

Site access: broad access to websites you visit (http(s)://*/*) is optional and requested when you enable site protection or connect a wallet from the extension, so we can inject our protection script and interact with the page's wallet provider on dApps. If you do not grant this access, in-page protection and wallet connect on normal tabs will not work until you allow it. Access to our API host is separate and used for the requests described above.

Notifications: the extension may show system notifications when we block or warn on a high-risk transaction or flag a suspicious domain, so you notice even if the tab is in the background.

3. How We Use Information

We process data for the following purposes:

3.1 Service Delivery

• Provide wallet protection, transaction analysis, and alerts

• Facilitate crypto-to-fiat payment functionality

3.2 Security and Fraud Prevention

• Detect malicious smart contracts and phishing attempts
• Prevent unauthorized wallet interactions
• Monitor for suspicious or anomalous behavior

3.3 AI Model Improvement

Train and refine machine learning models for:

• Threat detection
• Token risk scoring
• Threat intelligence

All such processing is conducted using aggregated or pseudonymized data where possible.

3.4 Communications

• Send service updates, alerts, and notifications
• Provide customer support
• Deliver security warnings in real time

3.5 Compliance and Legal Obligations

• Comply with applicable laws and regulatory requirements

6. Data Security

We implement industry-grade security measures, including:

• End-to-end encryption (where applicable)
• Secure API architecture
• Continuous monitoring and threat detection
• Zero-access design for sensitive wallet credentials
• AI-driven anomaly detection systems

Despite these safeguards, no system is entirely immune to risk. Users are encouraged to maintain strong personal security practices.

7. Data Retention

We retain data only as long as necessary to:

• Provide services
• Comply with legal obligations
• Resolve disputes
• Improve platform functionality

Blockchain data, by design, may remain permanently accessible on public ledgers.
