CalcGeo Cookie Policy

CalcGeo values digital privacy. We operate a zero-surveillance web experience: we do not employ third-party advertising cookies, retargeting pixels, or behavioral profiling trackers.

Zero Advertising Tracking Guarantee

CalcGeo does NOT utilize commercial ad networks, Google Remarketing, Meta Pixels, or cross-site fingerprinting beacons. Any cookies or local storage keys utilized by our platform exist exclusively for technical security or to remember your interface preferences locally on your machine.

1. Understanding Cookies & Web Storage

When you browse modern web applications, your browser can store small packets of text data to maintain continuity between page visits. These technologies primarily include:

HTTP Cookies:

Small text files sent by a web server and stored in your browser. Cookies are transmitted back to the server with subsequent HTTP requests to maintain session state or security tokens.

HTML5 Web Storage (localStorage & sessionStorage):

Client-side storage mechanisms built directly into your browser. Unlike cookies, localStorage data is never automatically transmitted to the server in HTTP request headers. It stays purely on your machine.

2. How CalcGeo Uses Storage Technologies

We strictly categorize all storage mechanisms utilized on CalcGeo into the following classifications:

A. Strictly Necessary Security Cookies

These cookies are vital for the operational integrity and security of CalcGeo. They enable edge firewalls (such as Cloudflare and Vercel edge protections) to detect coordinated bot attacks, mitigate distributed denial-of-service (DDoS) attempts, and maintain TLS session routing. You cannot disable these cookies without impairing website accessibility.

B. Functional Client Preferences (localStorage)

These key-value pairs reside solely in your browser's localStorage. We use them to remember your preferred country, state/province, or calculation currency, eliminating the friction of re-entering regional selections every time you visit. This data is never sent to our servers.

C. Commercial Advertising & Retargeting Cookies — NONE

CalcGeo contains zero third-party advertising cookies. We do not permit data brokers, social media platforms, or marketing networks to drop tracking pixels on your device.

3. Inventory of Stored Items

Below is an exhaustive register of the cookies and local storage keys that may be created during your visit:

4. How to Control, Block or Clear Cookies

You maintain total control over cookies and local storage through your browser settings. You can delete existing cookies, block all cookies, or configure alerts when cookies are dispatched.

5. Global Privacy Control (GPC) & Do Not Track (DNT)

CalcGeo honors browser-level privacy signals including Global Privacy Control (GPC) and Do Not Track (DNT). Because our platform does not sell personal information or participate in behavioral ad targeting, your privacy is completely respected whether these signals are enabled or not.
