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

This Cookie Policy explains how WallCalculator utilizes cookies, local storage tokens, and related web technologies to deliver reliable framing tools, maintain user interface preferences, and support third-party advertising partners.

1. What Are Cookies?

A cookie is a small text file placed on a computer, smartphone, or tablet when visiting a website. Cookies allow web applications to identify returning devices, preserve user display choices, and measure visitor traffic volume.

2. Categories of Cookies Used on WallCalculator

WallCalculator utilizes three specific categories of cookies and browser storage mechanisms:

  • Strictly Necessary / Functional Storage: WallCalculator uses browser local storage (specifically the localStorage['theme'] key) to remember whether a visitor prefers Dark Mode or Light Mode. This ensures consistent contrast upon subsequent visits without requiring server accounts.
  • Performance & Analytics Cookies: Google Analytics 4 sets first-party analytical cookies (such as _ga and _ga_*) to distinguish unique visitors and measure aggregate page engagement metrics. These cookies store anonymous client identifiers.
  • Advertising & Marketing Cookies: Third-party advertising vendors, including Google, utilize cookies to serve advertisements based on a user's prior visits to this and other websites across the web. These cookies measure advertisement effectiveness and prevent repetitive ad displays.

3. Managing and Disabling Cookies

Visitors have full control over cookie storage. Web browsers permit users to view stored cookies, delete existing cookies, or block cookies entirely:

  • Google Chrome: Settings > Privacy and security > Cookies and other site data.
  • Mozilla Firefox: Settings > Privacy & Security > Cookies and Site Data.
  • Apple Safari: Preferences > Privacy > Manage Website Data.
  • Microsoft Edge: Settings > Cookies and site permissions > Manage and delete cookies.

To opt out of interest-based advertising cookies from participating advertising networks, visit the Network Advertising Initiative Opt-Out Page or the Digital Advertising Alliance Consumer Choice Tool.
