What We Collect

BestCalc runs entirely in your browser. All calculations are performed client-side. We do not collect, store, or transmit any data you enter into our calculators.

Cookies & Consent

We use Google Consent Mode v2 with Google Funding Choices as our Consent Management Platform (CMP). EU/UK (GDPR) and California (CCPA) visitors will see a consent banner before any advertising cookies are set. You can change your consent choice at any time by clearing your browser cookies and revisiting the site.

• Google Analytics collects anonymized usage data by default (no advertising cookies)
• EU/UK and California visitors must consent before advertising or personalization cookies are set
• Without consent, Google AdSense serves non-personalized ads only

Analytics

We use Google Analytics (gtag.js) to understand which tools are popular and how visitors find us. Google Analytics may use cookies to collect anonymized usage data. You can opt out via Google Analytics Opt-out.

Advertising

We display ads via Google AdSense to support free access to our tools. When consent is granted, Google may use cookies to serve ads based on your interests. You can manage your ad preferences at Google Ads Settings.

For California residents (CCPA): You have the right to opt out of the sale or sharing of personal information. The consent banner provides this option, or you can manage your preferences at Google Ads Settings.

For EU/UK visitors (GDPR): No personal data is processed for advertising purposes without your explicit consent via the consent banner.
