Last updated: June 30, 2026
1. Introduction
This Privacy Policy explains how E-Trade Studio (“we”, “the team”, or “the developer”) collects, uses, stores, and protects your information when you use our desktop application.
E-Trade Studio is a trading signal processing application that runs locally on your computer. We are committed to protecting your privacy and ensuring you understand what information is handled and how.
By using E-Trade Studio, you agree to the practices described in this policy.
2. Information We Collect
2.1 Information Stored Locally (On Your Computer)
The following data is stored exclusively on your local machine in an encrypted local database. It is never transmitted to our servers or any external service (except as noted in Section 3):
| Category | Details |
|---|---|
| Signal Account Credentials | Phone number, session data, and authentication tokens used to connect to your signal sources |
| Trading Account Credentials | Broker server addresses, login numbers, account passwords, API keys and secrets for MT4, MT5, Binance, and Bybit accounts |
| Trading Data | Trading signals received, signal parsing results, trade routing configurations, and audit trail of signal processing events |
| Application Configuration | App preferences, UI settings, and feature grant / license status cache |
2.2 Device Fingerprint (Hardware Information)
For license activation and device binding purposes, we collect the following hardware information. This data is hashed using SHA-256 before any transmission to our license server:
- Operating system platform (Windows, macOS, or Linux)
- CPU model
- Total system memory
- Windows MachineGUID (Windows registry identifier)
- Primary network interface MAC address
- Disk serial number (Windows only)
- Hostname
This fingerprint is used solely to bind your license to your device. The raw values are never stored — only the SHA-256 hash.

When you purchase a license, the following information is collected via our payment processor and license server:
- Email address (for license delivery and support communication)
- First name and last name (customer information)
- Telegram username (optional, for support purposes)
- Device fingerprint hash (for license activation / binding)
3. How We Use Your Information
3.1 Local-Only Processing
All trading signal processing, parsing, routing, and execution happens entirely on your local machine. Your trading data, signal content, and account credentials are processed locally and are not sent to any external service.
3.2 License Validation and Activation
The only external server E-Trade Studio connects to is our license server at license.etradestudio.com. This connection is used exclusively for:
- Activating licenses — Binding a purchased license to your device
- Validating licenses — Checking that your license is active and valid
- Managing trials — Starting and validating free trials for features
- Receiving license updates — Real-time notifications of license changes via WebSocket
All communication with the license server is encrypted over HTTPS / WSS.
3.3 Purpose Summary
| Purpose | Data Used | Storage Location |
|---|---|---|
| Signal processing and routing | Trading data, credentials | Local only |
| License activation / validation | Device fingerprint hash, email | License server |
| Purchase processing | Email, name, payment info | License server |
