Privacy Policy

Last updated: August 25, 2026

This is an English reference translation. The Japanese version is authoritative.

1. Information We Collect

By default, ShieldGuard does not transmit the contents of your files, personal information, or usage data to external servers. Scan results and detection history are stored only in a data folder on your own PC (by default, %USERPROFILE%\.shieldguard).

2. External Communication

The product communicates with external servers only for the following purposes.

• Virus definition database updates: Fetches the latest YARA rules and hash signatures from a signature repository on GitHub.
• Community threat-intelligence sharing (optional, off by default): Only if you enable it, statistical information about detected threats is sent to a shared server. Neither the files themselves nor personally identifying information is sent. This feature can be disabled at any time.
• VirusTotal integration (optional): If you configure and enable an API key, file hash values are looked up against VirusTotal.

3. Cookies & Analytics (About This Website)

This website (our sales page) does not currently use analytics tools or cookie-based tracking. If this changes in the future, we will update this policy accordingly.

4. Disclosure to Third Parties

We do not disclose your information to third parties except where required by law.

5. Contact
