End-User License Agreement (EULA)

1. License Grant

VisualHFT ("Software") is licensed, not sold. Subject to your compliance with this EULA, we grant you a non-exclusive, non-transferable, revocable right to install and use one copy of the Software on a single device you control.

2. Third-Party Data Sources

The Software can connect to third-party data providers (e.g., market data feeds, analytics APIs). You must hold and maintain all required subscriptions or licenses for any data sources you use. We are not a data vendor and do not supply any third-party data.

3. Restrictions

You may not, directly or indirectly:

• Redistribute, sublicense, sell, lease or otherwise provide any portion of the Software or any data (raw or derived) to any third party.
• Bypass or disable any licensing, entitlement or watermarking features.
• Reverse-engineer, decompile or disassemble the Software, except to the extent permitted by applicable law.

4. Derived Data

You may compute studies, indicators or other analytics ("Derived Data") locally for your own internal use. Any redistribution of Derived Data outside your licensed organization requires separate permission from the underlying data provider.

5. Third-Party Relations

We have no responsibility for any agreements, disputes, or actions between you and any third-party data provider. You alone are responsible for obtaining, maintaining, and complying with your license or subscription terms with those providers, and for resolving any claims or fees they may impose.

6. Compliance & Audit Rights

• You agree to comply with all applicable laws and third-party license terms.
• Upon reasonable notice, we may audit your use of the Software (including logs of export or data-connection events) to verify compliance. You agree to cooperate with any such audit.

7. Indemnification

You will defend, indemnify and hold us harmless from any claims, liabilities, damages or expenses arising out of your misuse of the Software or your breach of any third-party license.

8. Termination

This license automatically terminates if you fail to comply with any term. Upon termination, you must cease all use of the Software and delete all copies.

9. Disclaimer & Limitation of Liability

The Software is provided "as-is," with no warranties. We are not liable for any damages arising from use or inability to use the Software, including loss of data or profits.

10. Governing Law

This EULA is governed by the laws of the State of Florida, United States, without regard to conflict-of-law principles.

11. Telemetry & Diagnostics

To improve product quality and diagnose issues, the Software collects: usage events (module usage and control clicks identified by name), session and heartbeat liveness signals, and a whitelisted subset of your local settings; error and crash reports; your IP address, recorded server-side for abuse prevention; a one-way hashed machine identifier; and the application version. This telemetry data is automatically deleted after 90 days.

We never collect market data, symbols, prices, orders, exchange API credentials, or your raw settings.json file.

12. Automatic Updates

The Software periodically checks for updates over HTTPS and, when one is available, downloads it in the background without interrupting your current session. The update is applied automatically the next time you restart the Software. Every update package is Authenticode-signed by our verified publisher identity and timestamped before it is offered; installation fails closed if a signature, timestamp, or package checksum does not validate, and the Software continues running your last working version if an update cannot be applied. Automatic update checks cannot be disabled.

13. Acceptance

By installing or using the Software, you acknowledge that you have read, understood and agree to be bound by this EULA.
