6. Device Security & 1-Device Policy

6.1 Why We Collect Device Information

We collect and store device information to enforce our 1-device-per-account security policy. This helps us:

• Prevent Account Sharing: Ensure each account is used by only one person on one device
• Detect Fraud: Identify suspicious multi-device login attempts
• Enhance Security: Protect your account from unauthorized access
• Prevent Abuse: Stop users from exploiting features (SheerApps Bonus, referrals) across multiple devices

6.2 What Device Information We Collect

• Device Identifier: A unique ID generated by your device (hashed with SHA-256 encryption before storage for privacy protection)
• Device Name/Model: The name and model of your device (e.g., "Samsung SM-G960F") for your reference in Account Management
• Device Binding Timestamp: When your device was first bound to your account
• Last Login IP Address: For security monitoring (optional, not tied to device binding)

6.3 How the 1-Device Policy Works

Login Process:

• First Login: When you log in for the first time (or after account deletion), your device is automatically bound to your account
• Same Device Login: If you log in again from the same device, access is granted immediately
• Different Device Login: If you attempt to log in from a different device:
  • System detects device conflict
  • Alert shown: "You are logged into multiple devices at the same time. We only allow 1 login to 1 device. For security reasons, we've ended all sessions."
  • All sessions terminated on all devices
  • You must log in again to continue

6.4 App Launch Device Check

Every time you open the app:

• The app checks if your device ID matches the bound device in our database
• If a mismatch is detected (someone logged in from another device), you'll be automatically logged out for security
• This ensures your account remains secure even if you forgot to log out on another device

6.5 Device Data Retention & Deletion

• How Long We Keep It: Device information is stored for the duration of your active account
• Account Deletion: Device ID and binding information are immediately cleared when you delete your account
• Recovery Period: During the 30-day recovery period, device binding is cleared (not restored)
• New Device After Deletion: After account deletion, you can create a new account on the same device
• Device Upgrade: If you get a new device, you can transfer your account by logging in (old device will be automatically unbound)

6.6 Privacy & Security

• Hashed Storage: We hash device IDs using SHA-256 encryption before storing them, so the raw device ID is never stored in plain text
• No Third-Party Sharing: Device IDs are NEVER shared with any third parties
• Purpose-Limited: Device data is used ONLY for account security and fraud prevention
• No Tracking: We do NOT use device IDs for advertising, analytics, or cross-app tracking

6.7 Legitimate Device Changes

We understand you may need to change devices. Here's how it works:

• New Phone: Simply log in from your new device. The old device will be automatically unbound.
• Lost/Stolen Device: Log in from your new device to secure your account and unbind the lost device.
• Device Reset: Your device ID may change after a factory reset. Log in again to rebind.
