Cookie Policy

This policy explains how Calcumetrics (calcumetrics.com) uses cookies and browser local storage, their exact technical purposes, and how you can control your preferences.

1. Functional browser storage (localStorage)

We use client-side localStorage solely to remember your immediate UI preferences between visits:

• cm_currency: Stores your preferred display currency symbol (e.g. INR, USD, EUR, GBP) for universal calculators.
• cm_theme: Stores your dark mode or light mode appearance preference.
• cm_consent: Stores your analytics cookie choice from the cookie banner or Cookie settings.

This data stays strictly on your local device. It is never transmitted to our servers or accessible to third parties.

2. Web analytics: Google Analytics 4 & Cloudflare

We utilize two analytics layers to ensure platform stability and understand aggregate visitor usage:

• Google Analytics 4 (First-party cookies): GA4 may set first-party cookies (such as _ga and _ga_*) to distinguish anonymous browser sessions. GA4 is configured with Google Consent Mode v2 (defaulting ad storage and personalization to denied). Visitors in the EEA, United Kingdom, and Switzerland are asked first: analytics cookies stay off until you accept them. Calculator inputs, financial figures, and loan details are strictly excluded from all telemetry.
• Cloudflare Web Analytics (Cookieless): Provides aggregate, privacy-first pageview and performance measurements without using cookies, local storage, or device fingerprinting.

Embedded calculator widgets: Our calculator widgets embedded on other websites (served from calcumetrics.com/embed/) set no cookies, use no local storage, and load no Google Analytics or advertising scripts.

3. Advertising cookies (Google AdSense)

Calcumetrics plans to display third-party advertisements served by Google AdSense to keep our tools free. Advertising cookies are not set today; before ads are enabled, we will add a Google-certified consent platform for EEA, UK, and Swiss visitors and update this policy.

• Third-party vendors, including Google, use cookies (such as the DoubleClick cookie) to serve ads based on prior visits to this website or other websites on the Internet.
• Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visits to our site and other sites across the Internet.
• You can manage or opt out of personalized advertising at Google Ad Settings or via www.aboutads.info.

4. Self-hosted typography & zero external font tracking

All web fonts (including Inter and Playfair Display) are self-hosted locally directly on our own domain servers. We do not load fonts, scripts, or stylesheets from Google Fonts or third-party CDNs, ensuring that your IP address and browser headers are never transmitted to external font services.

5. How to control and delete cookies and storage

You can turn analytics cookies on or off at any time with Cookie settings in the site footer; turning them off also deletes existing _ga cookies. You can clear your stored preferences (such as remembered currency) and delete cookies at any time by clearing your browser's local storage and cache in your browser settings. To opt out of interest-based advertising across participating networks, you may visit the Digital Advertising Alliance opt-out or Google Ad Settings.

6. Questions and updates

If you have questions about our cookie or local storage practices, please contact us at hello@calcumetrics.com. We update this policy whenever storage mechanisms change.
