Cookie Policy
Last updated: September 1, 2026
This Cookie Policy explains what cookies and local browser storage technologies are, how CalcMaster Tools uses them, and your choices regarding cookie management.
1. What Are Cookies and Local Storage?
Cookies are small text files that are placed on your computer or mobile device by websites that you visit. Browser local storage (localStorage) is a modern web standard that allows websites to store small configuration values directly in your browser without transmitting them over network requests.
2. How CalcMaster Tools Uses Cookies & Local Storage
We believe in minimal, purposeful data storage:
- Theme Preferences: We use browser
localStorageto store your display preference (data-theme: "dark"or"light") so the website maintains your selected visual theme on future page visits. - No Personal Calculator Data: None of your calculator inputs (e.g. loan sums, dates, or body weights) are stored in cookies or transferred to server cookies.
3. Third-Party & Advertising Cookies
When third-party advertising partners such as Google AdSense are enabled on our platform, these third parties may place cookies on your browser to measure advertisement effectiveness and display relevant advertisements based on your general browsing interests across the web.
4. Managing and Disabling Cookies
You can control and manage cookies through your web browser settings. Most browsers allow you to:
- View what cookies are stored and delete them individually
- Block third-party cookies
- Block cookies from particular sites
- Block all cookies from being set
- Clear all cookies when you close your browser
Please note that disabling local storage may cause the website to revert to your system default theme on each page load.
5. Changes to This Policy
We may update our Cookie Policy periodically. Any updates will be reflected directly on this page with an updated timestamp.
