Cookie Policy

What are cookies and local storage?

Cookies are small alphanumeric text files placed on your browser or hard drive by websites you visit. They are widely implemented across the web to maintain secure user sessions, remember site configuration preferences, and provide aggregated reporting telemetry.

In addition to traditional HTTP cookies, our website leverages modern HTML5 Local Storage. Unlike cookies, Local Storage data does not get transmitted with every web request, reducing network bandwidth while preserving your unit preferences.

Categories of cookies we utilize

1. Strictly Necessary Cookies: Essential for core website navigation, routing, cybersecurity rate-limiting, and asset delivery via content delivery networks (CDNs). The site cannot function properly without these.

2. Functional Preferences (Local Storage): Used to store your active unit selection (Square Feet vs. Square Meters, US Dollars vs. British Pounds / Euros) and preferred calculation mode. This data remains strictly within your browser sandbox.

3. Performance & Analytics Cookies: Deployed via Google Analytics to aggregate anonymous metrics such as page interaction time, device viewport sizes, and popular calculator routes. These insights guide our design and usability improvements.

4. Advertising Cookies: Utilized by Google AdSense and accredited advertising exchange partners to deliver relevant, non-intrusive advertisements and prevent fraudulent ad impressions.

Third-party services and lifespans

Session cookies expire automatically when you terminate your browser session. Persistent cookies remain active on your hard drive for a defined period (typically ranging between 30 days and 24 months) or until manually purged by the user.

Third-party advertising and analytics vendors set cookies subject to their independent privacy policies. We do not transmit sensitive personal identifiers to any analytics partner.

How to manage, block, or delete cookies

You hold full autonomy over cookie permissions. You can modify your browser settings to accept all cookies, alert you whenever a cookie is issued, or reject cookies altogether.

Furthermore, our website respects Global Privacy Control (GPC) and Do Not Track (DNT) header signals communicated by compliant browser applications. Note that disabling cookies entirely may impair dynamic styling or require re-selecting your preferred units on each visit.

Policy revisions and updates

We may periodically revise this Cookie Policy to reflect technical architecture improvements or evolving global data privacy statutes. Continued navigation of the site following updates indicates your consent.
