Cookie Policy for Skiller Calculator Hub

August 26, 2026

Introduction

At Skiller Calculator Hub, we are committed to protecting your privacy and ensuring a transparent online experience. This Cookie Policy explains what cookies are, how we use them, and how you can manage your preferences when using our free online calculators.

What Are Cookies?

Cookies are small text files stored on your device (computer, tablet, or mobile) when you visit a website. They are widely used to make websites work more efficiently, provide a better browsing experience, and provide information to the owners of the site.

How We Use Cookies

We use cookies and similar technologies (like local storage) for several essential purposes:

  • Essential Functionality: To remember your login status (Email, Google, or GitHub) so you can access your personal cabinet and saved favorites.
  • Calculator Performance: To securely cache your entered numbers and results locally on your device so you don’t lose them if you accidentally refresh the page.
  • Analytics and Improvements: To understand how visitors interact with our 150+ calculators, helping us improve performance and tool usability.
  • User Preferences: To remember your preferred interface settings.

Types of Cookies We Use

  • Strictly Necessary Cookies: These are required for the core functionality of the site, such as login, security, and proper page navigation. These cannot be disabled.
  • Performance and Analytics Cookies: These help us track visits and traffic sources so we can measure and improve the performance of our site. They help us know which pages are the most and least popular. All data is aggregated and anonymous.
  • Functional Cookies: These allow the website to remember choices you make (such as your saved favorite calculators in your personal cabinet) to provide enhanced, more personal features.
  • Targeting Cookies: These cookies may be set through our site by our advertising partners (if used in the future). They may be used by those companies to build a profile of your interests and show you relevant advertisements elsewhere.

Third-Party Cookies

In addition to our own cookies, we may also use various third-party cookies to support our platform. These include:

  • Google Sign-In: To securely authenticate you via your Google account.
  • GitHub Sign-In: To securely authenticate you via your GitHub account.
  • Analytics Services (e.g., Google Analytics): To help us understand user behavior.
  • CookieYes: To remember your consent preferences regarding cookie usage.

Data Stored in Your Account

When you log in to your personal cabinet (via Email, Google, or GitHub), we store encrypted data on our secure servers. This includes your favorites and your calculation history. We never sell your personal data. All entered metrics are cached locally and encrypted for your security.

Managing Your Cookie Preferences

You can accept or reject non-essential cookies via the cookie consent banner provided by our CookieYes plugin. You can also set your browser to refuse all or some browser cookies, or alert you when cookies are being sent. If you disable strictly necessary cookies, parts of the site, such as the login feature for your personal cabinet, may not function correctly. You can also clear your browser’s local storage at any time to erase cached calculator inputs.

Updates to This Policy

We may update this Cookie Policy from time to time to reflect changes in technology, regulation, or our business practices. Any changes will be posted on this page with a revised date. We encourage you to review this policy periodically to stay informed about how we protect your data.
