Cookie Policy
Last Updated: May 31, 2026This Cookie Policy explains how Calculent.com ("we", "us", and "our") uses cookies and similar local storage technologies to recognize you when you visit our website at https://calculent.com. It explains what these technologies are and why we use them, as well as your rights to control our use of them.
1. What Are Cookies?
Cookies are small data files that are placed on your computer or mobile device when you visit a website. Cookies are widely used by website owners in order to make their websites work, or to work more efficiently, as well as to provide reporting information.
Cookies set by the website owner (in this case, Calculent.com) are called "first-party cookies". Cookies set by parties other than the website owner are called "third-party cookies". Third-party cookies enable third-party features or functionality to be provided on or through the website (e.g., advertising, interactive content, and analytics).
2. How We Use Cookies & Browser Storage
Unlike most modern platforms, Calculent.com operates under a strict **zero-server-footprint design philosophy**. This means we do not log or store your calculations on any remote database. To achieve this privacy while delivering high performance, we rely heavily on safe, local browser storage solutions:
- Local Storage & Session Storage: Used entirely client-side to save your settings. For example, it stores whether you have activated Dark Mode, your bookmarked tools, and your recently visited tools. This is never transmitted to our servers.
- Cache Storage (Service Workers): Used to store static website code, styling sheets, scripts, and fonts. This allows Calculent.com to be PWA-enabled, loading instantly and working perfectly offline.
- Essential Cookies: Extremely basic session items that may be utilized to maintain standard security checks during navigation.
3. Advertising Partners & DoubleClick DART Cookies (Google AdSense)
We may display advertisement banners through Google AdSense to offset the cost of hosting and maintain our platform as a free service. Google AdSense uses cookies to serve contextual and personalized ads to visitors:
- Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visit to Calculent.com and/or other sites on the Internet.
- Google utilizes the DoubleClick DART cookie to track user browsing behavior across the web to serve relevant, personalized advertisements.
- You may opt-out of personalized advertising by visiting Google Ads Settings or managing your preferences in Google's Advertising Privacy & Terms page.
4. How to Manage and Disable Cookies
You have the right to decide whether to accept or reject cookies. You can exercise your cookie rights by setting your preferences in the Cookie Consent Banner that appears when you first visit our site, or by adjusting your web browser controls:
- Browser Controls: You can set or amend your web browser controls to accept or refuse cookies. If you choose to reject cookies, you may still use our website, though your access to some functionality and areas of our website may be restricted. Visit your browser's help menu for more information.
- Clearing Storage: You can clear all local storage, session storage, and cached Service Workers at any time using your browser's "Clear Browsing Data" or "Clear Cache" settings. This will completely reset your Calculent configuration (bookmarks, recent tools, and dark mode toggles).
5. CCPA and GDPR Privacy Protections
Under European General Data Protection Regulation (GDPR) and California privacy acts (CCPA/CPRA), we are fully aligned with the strict standards of digital privacy. Because Calculent.com processes all input calculations **locally inside your device's browser memory**, we do not collect, store, sell, or rent your private financial data or calculation outputs. Third-party ad cookies are governed by Google's strict opt-out compliance models, as outlined in Section 3.
6. Changes to this Cookie Policy
We may update this Cookie Policy from time to time in order to reflect, for example, changes to the cookies we use or for other operational, legal, or regulatory reasons. Please therefore re-visit this Cookie Policy regularly to stay informed about our use of cookies and related technologies.
