Privacy Policy
Last updated: September 2026 · Effective Date: January 1, 2026
Summary of Core Privacy Principles
- Client-Side Calculation: All calculations you enter (dimensions, thickness, pricing) are processed locally in your browser and never sold.
- No Mandatory Accounts: BuildCalc is 100% free and does not require account creation or registration to use any calculation tools.
- Local Storage: Your measurement units, language selection, and saved projects are stored in your device's browser localStorage for your convenience.
1. Information We Collect
We believe in minimal data collection. When you use BuildCalc, we may collect information in the following ways:
- Voluntary Information: If you submit an optional request for contractor bids or contact us for support, we receive the name, email address, phone number, and postal code that you provide.
- Local Storage Preferences: We use browser localStorage to remember your preferred language (English, Spanish, Hindi, etc.) and measurement system (Metric vs. Imperial).
- Standard Web Logs: Like virtually all websites, our hosting servers automatically log standard anonymous technical data such as IP address, browser user-agent, operating system, referring URL, and pages visited.
2. How We Use Your Information
We use collected data solely for:
- Delivering accurate instant calculation tools and unit conversions.
- Fulfilling voluntary requests for local contractor estimates and material bids.
- Monitoring site uptime, infrastructure security, and performance metrics.
- Complying with applicable legal obligations.
3. Cookies and Analytics
BuildCalc may use standard first-party cookies and privacy-respecting analytics to analyze anonymous visitor traffic patterns and optimize mobile usability. You can configure your browser to reject cookies or notify you when cookies are being set.
4. Third-Party Services & External Links
Our site may contain links to external third-party services, supplier directories, or industry reference guides (e.g. ASTM standard specifications, state transportation departments). BuildCalc is not responsible for the privacy practices or content of third-party domains.
5. Data Retention & Your Rights
Because calculation inputs are executed in your browser runtime and saved in your device's browser memory, you can clear all stored calculator history and language preferences at any time by clearing your browser's site data and cookies.
