Privacy Policy

The headline

Every calculator executes locally in JavaScript within your browser. The numbers you type — salaries, balances, rates — are never transmitted to our servers, logged, stored, or sold. There are no accounts, so there is nothing to breach.

Information collected automatically

Like nearly all websites, our hosting infrastructure processes standard technical data when pages load: IP addresses (largely anonymized/anonymizable at the CDN layer), user agents, referring URLs, and timestamps. This data enables delivery, security, and abuse prevention.

Analytics

We use aggregate, privacy-respecting analytics to understand which pages are useful. Analytics see page views and referrers — not calculator input values.

Advertising

Ads keep the site free. Advertising partners (such as Google AdSense) may set cookies or use similar technologies to measure and personalize ads under their own policies. You can manage ad personalization through Google Ads Settings or opt out via industry tools like the DAA and NAI choice pages. Browser-level cookie blocking also works against most ad tracking.

Cookies

Essential cookies/local storage may remember interface preferences. Third-party ad cookies fall under the advertising paragraph above. No login cookies exist because there are no logins.

Data sharing

We do not sell personal information. Data shared with processors is limited to hosting, analytics, and advertising functions described above, governed by contract.

Your choices

• Use any calculator fully with ad-blocking enabled if you wish.
• Clear cookies anytime without losing access.
• Email us at privacy@calcprimehq.com with questions or requests.

Children

CalcPrimeHQ targets adults making financial decisions and does not knowingly collect information from children under 13.
