Privacy Policy
Last updated: March 21, 2026
1. Introduction
Construction Estimator (“constructionestimator.co,” “we,” “us,” or “our”) respects your privacy and is committed to protecting your personal information. This Privacy Policy explains what data we collect, how we use it, and your rights regarding that data when you use our AI-powered construction cost estimation platform (“the Service”).
2. Information We Collect
2.1 Information You Provide
- Account information: When you create an account, we collect your email address, name, and optionally your company name and phone number.
- Project data: Information you enter into our calculators, including square footage, material selections, ZIP codes, and project descriptions.
- Photos: If you use our AI photo analysis feature, we process the images you upload to generate cost estimates. Photos are stored securely and used only for estimate generation.
- Payment information: When you subscribe to a paid plan, payment processing is handled entirely by Stripe. We do not store your credit card numbers, bank account details, or other payment credentials on our servers.
- Communications: If you contact us via email, we retain the correspondence to respond to your inquiry and improve our Service.
2.2 Information Collected Automatically
- Usage data: We track how many estimates you generate per month for the purpose of enforcing plan limits. For anonymous users, this is tied to a hashed IP address (not your raw IP).
- Device and browser information: We collect standard log data including browser type, operating system, referring URL, and pages viewed.
- Cookies and tracking technologies: We use cookies and similar technologies for analytics and advertising (see Section 5).

We do not sell your personal information to third parties. We do not use your project data or photos for any purpose other than providing the Service to you.
