Last updated: 2026-07-19

BTCMind (“we”, “the Service”) is an AI crypto-trading copilot operated by ZHEN GUO. This Policy explains how we collect, use, and protect your personal information. By continuing to use the Service, you agree to this Policy.

1. Information We Collect

• Account identity: email address; if you sign in with Apple / Google, we also collect the platform-issued unique user ID (Apple sub / Google sub).
• OKX API credentials: OKX API Key, Secret, Passphrase that you choose to connect. All credentials are stored on our server with AES-256-GCM encryption. We never log them in plaintext.
• Trading records: when you enable auto-trading, we log orders executed under your account (symbol, price, quantity, strategy tag, timestamp) for PnL reporting and explainability.
• Conversation content: your chats with the Claw AI copilot are stored for context continuity and history browsing. You may clear them at any time.
• Access status information: if we grant complimentary access for onboarding, testing, or review purposes, we may store the access start time, end time, and related internal notes.
• Device information: iOS / Android UDID (for ad-hoc TestFlight provisioning only), app version, OS version.
• Usage logs: API call timestamps, error logs, client crash reports. Used for reliability diagnostics.
• Website and advertising measurement: pages visited, referrer parameters, browser and device type, and advertising click attribution identifiers. Ahrefs Analytics and the X Pixel process this data for aggregate analytics and campaign measurement.
