1. What Are Cookies?
Cookies are small text files placed on your device when you visit a website. They help websites work efficiently and provide owners with information about how users interact with their pages.
CalculatorSky uses cookies to remember your preferences, keep your session secure, and understand how our tools are used so we can improve them.
Cookie-Free Calculations
All calculator logic runs entirely in your browser. Your inputs — loan amounts, salaries, investment figures — are never sent to our servers. Cookies only handle preferences and analytics, never your calculation data.
2. How We Use Cookies
We use cookies for the following purposes:
- Theme preference — Remembering whether you prefer light or dark mode so you don't have to set it on every visit.
- Session management — Keeping your session active and secure while you navigate between calculator pages.
- Analytics — Understanding which calculators are most popular, how users navigate the site, and where we can improve (only with your consent).
- Advertising — Serving relevant ads through Google AdSense to keep CalculatorSky free for everyone (only with your consent).
We do not use cookies to collect personal identification information, track you across other websites, or sell your data to third parties.
3. Types of Cookies We Use
Essential Cookies
These cookies are required for the website to function. They cannot be disabled. They do not store personally identifiable information.
Preference Cookies
These remember your settings (such as dark/light mode) so your experience is consistent across visits. You can clear these by clearing your browser's local storage.
Analytics Cookies
Used via Google Analytics (GA4) to collect aggregated, anonymous data about how visitors use CalculatorSky. This helps us understand traffic patterns and improve our tools. These are only loaded after you give consent.
Advertising Cookies
Google AdSense may place cookies to show relevant advertisements. These cookies may track your browsing across websites to personalise ads. They are only active with your consent.

7. Your Choices
When you first visit CalculatorSky, a cookie consent banner gives you a clear choice:
- Accept All — Enables analytics and advertising cookies in addition to essential ones.
- Decline — Only essential cookies run. Analytics and advertising cookies are blocked.
You can change your preference at any time by clearing your browser's localStorage for calculatorsky.com and reloading the page. The consent banner will reappear.
Essential Cookies Always Active
Theme preference and consent records are stored in your browser's localStorage (not traditional cookies) and are strictly necessary for the site to function correctly. These cannot be disabled.
8. Cookie Consent
CalculatorSky complies with GDPR, ePrivacy Directive, and other applicable privacy regulations. We obtain your explicit consent before loading any non-essential cookies.
Our consent system works as follows:
- A consent banner is shown on your first visit.
- Your choice is stored locally and respected on all subsequent pages.
- Analytics (GA4) and advertising (AdSense) only load after "Accept All" is clicked.
- Declining does not affect your ability to use any calculator or converter.
9. Policy Updates
We may update this Cookie Policy from time to time to reflect changes in our practices, technology, or legal requirements. When we make significant changes, we will update the "Last Updated" date at the top of this page.
We encourage you to review this policy periodically. Continued use of CalculatorSky after changes are posted constitutes your acceptance of the updated policy.
