Privacy Policy: Data Protection & Cookies

Effective Date: September 30, 2026 · Last Updated: September 30, 2026

WallCalculator (accessible at https://wallcalculator.app) is committed to protecting visitor privacy. This Privacy Policy details the types of information gathered when accessing the calculators, how that data is utilized, and the rights users maintain regarding personal privacy and third-party advertising cookies.

1. Local Client-Side Calculation Processing

All architectural dimensions, wall lengths, wall heights, stud spacing selections, rough opening counts, drywall specifications, and material cost estimations entered into WallCalculator are processed strictly on the client device inside the web browser using client-side JavaScript.

Project dimensions are never transmitted to external databases, cloud servers, or third-party storage. When the browser tab is refreshed or closed, user input data is cleared unless stored temporarily in the browser local storage for interface theme preferences.

2. Google Advertising Cookies (Google AdSense)

Third-party advertising vendors, including Google, serve advertisements on WallCalculator to maintain free access to all construction estimation tools.

  • Advertising Cookies: Google uses cookies to serve ads on WallCalculator based on a user's prior visits to this website and other websites across the Internet.
  • Personalized Advertising: Google's use of advertising cookies enables it and its partners to serve targeted ads to users based on their browsing visits to WallCalculator and other sites on the World Wide Web.
  • Opting Out of Personalized Advertising: Users may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, users can opt out of a third-party vendor's use of cookies for personalized advertising by visiting AboutAds Choices.

3. Web Analytics (Google Analytics 4)

WallCalculator utilizes Google Analytics 4 (GA4) to evaluate website performance, technical reliability, and user navigation trends. GA4 collects anonymized aggregate data, including device category, screen resolution, browser type, geographic region (country level), pages viewed, and session duration.

IP addresses are anonymized automatically by Google Analytics. This information is utilized solely to optimize page load speeds, improve mobile usability, and identify software errors.

4. Log Files

Like standard web platforms, hosting providers (such as Cloudflare Pages) maintain server log files recording visitor internet protocol (IP) addresses, browser user-agents, referring and exit pages, date and time stamps, and requested resource paths. This data is not linked to personally identifiable information and is maintained strictly for network security and DDoS mitigation.

5. Third-Party Links

The educational articles on WallCalculator contain outbound links to external building code councils and industry organizations (such as the International Code Council and Gypsum Association). WallCalculator has no control over the content or privacy practices of external third-party domains.
