Privacy Policy

1. Who We Are

ChangeGuard LLC ("ChangeGuard," "we," "us," or "our") operates the ChangeGuard construction document intelligence service, which reviews the drawings, specifications, contracts, addenda and trade scopes in a document set and produces cited review items. Contact us at admin@changeguardsoftware.com.

2. Data We Collect

• Account information: Email address, name (optional), and password (stored as a one-way cryptographic hash; we never store your plaintext password).
• Uploaded documents: Construction drawings, contracts, and scope sheets you submit for review. These are stored temporarily on our servers.
• Project metadata: Project name, file sizes, review timestamps, and results.
• Usage data: Page visits, interactions, referral information, server logs, IP addresses, and browser information for service analytics, security, and debugging.

3. How We Use Your Data

• To authenticate you and provide the Service.
• To review your uploaded documents and produce the requested work products.
• To send you email notifications when your work product is ready (if you provide an email).
• To improve the reliability and performance of the Service.

4. Third-Party Processing

Your documents remain yours. They are processed only to provide the requested service and may be handled by the disclosed service providers required for delivery. Access, retention, and deletion follow the engagement and our published policies. Anthropic processes document content only to provide the requested review.

5. Data Retention

• Uploaded project documents and delivered work products are retained according to the applicable agreement or, for request uploads, the 30-day intake retention. We send an advance email warning before scheduled deletion.
• Documents uploaded through a website review request are deleted after 30 days.

• Website analytics events are retained for up to 400 days.
• Account information is retained until you delete your account.
• Job metadata (project name, status, timestamps) is retained for account history purposes.

6. Data Sharing

We do not sell, rent, or share your personal data or uploaded documents with third parties except:

• Anthropic, our document analysis provider, solely to perform the analysis you request
• Our hosting and infrastructure providers (under data processing agreements)
• When required by law or court order

7. Cookies and Sessions

We use first-party cookies for form security, authentication, and website analytics. We set no third-party or advertising cookies.

If your browser sends a Do Not Track or Global Privacy Control signal, we do not set cg_vid or cg_sid, and we discard website analytics events server-side.

8. Your Rights

You have the right to:

To exercise these rights, contact us at admin@changeguardsoftware.com. We will respond within 30 days.

9. Security

We implement industry-standard security measures including encrypted connections (HTTPS), hashed passwords (using scrypt), and access controls. No internet transmission is 100% secure; use the Service at your own risk for highly sensitive materials.
