Politique de Cookies

Last Updated: March 2025

This Cookies Policy explains what cookies and similar tracking technologies are, how Calculateur de Ratio (https://www.ratiocalculator.net) uses them, and what choices you have regarding their use.

1. What Are Cookies & Local Storage?

Cookies are small text files that websites store on your computer, tablet, or smartphone when you visit them. They help websites remember your preferences, keep you logged in, and understand how the site is used.

Local Storage (HTML5 Web Storage): In addition to standard HTTP cookies, modern web applications use browser local storage. Local storage allows web pages to store small amounts of data directly in your browser without sending it back and forth to the server with every web request, resulting in faster and more private page loads.

2. How Ratio Calculator Uses Cookies & Local Storage

Ratio Calculator uses minimal cookies and local storage strictly to ensure site stability, preserve your preferred user settings, and display relevant educational content:

  • Language & Regional Preferences: When you choose one of our 18 supported languages, your preference is stored in local storage so that your selected locale is maintained as you navigate between calculator tools.
  • Cookie Consent Confirmation: When you click "Accept Cookies" on our homepage banner, a simple status indicator is saved in your browser's local storage (cookie_consent) so you are not prompted repeatedly on every visit.
  • Zero Mathematical Data Logging: All calculation inputs (such as proportions, ratios, recipe scaling, and gear dimensions) are processed exclusively on your device via client-side JavaScript. We never store, log, or transmit your calculation formulas or numeric entries via cookies.

3. Types of Cookies We Use

A. Essential & Preference Storage (First-Party)

These are necessary for the website to function properly. They remember your language selection, dark/light theme preference, and your cookie consent status. They do not track your personal identity across other websites.

B. Performance & Analytics Cookies

We may use privacy-compliant web analytics tools (such as Google Analytics) to collect aggregate, anonymized metrics on page load times, popular calculator tools, and general visitor device types. This data helps us improve tool responsiveness and calculation algorithms.

To keep all Ratio Calculator tools completely free and accessible without mandatory subscriptions, third-party advertising partners (including Google AdSense) may set cookies on your browser to deliver contextually relevant advertisements.
