Privacy Policy
Last updated: October 1, 2026
This Privacy Policy explains how AllCalculators ("we", "us", or "our") handles information when you visit allcalculators.pro (the "Site"). We built this Site to be useful without requiring you to hand over personal information, and this policy describes exactly what we do and don't collect.
1. Calculator inputs stay in your browser
Every calculator on this Site runs entirely client-side. The numbers you type into a calculator — your weight, income, loan amount, dates, or any other input — are processed directly in your browser using JavaScript and are never transmitted to, or stored on, our servers. We have no record of what you calculate.
The only personal details we collect are the ones you choose to give us through the optional Pro early-access form described in section 5.
2. Information collected automatically
Like most websites, our hosting and analytics infrastructure automatically logs standard technical information when you visit, such as your IP address, browser type, device type, referring page, and the pages you view. This information is used in aggregate to understand traffic patterns and improve the Site, and is not used to identify you personally.
3. Cookies and advertising
We may use cookies and similar technologies for analytics and to serve advertising, including through Google AdSense. Google and its partners may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising by visiting Google Ads Settings, and you can manage or disable cookies generally through your browser settings.
4. Third-party services
We may use third-party services such as Google Analytics and Google AdSense to understand Site usage and display advertising. These providers may collect information as described in their own privacy policies, which we encourage you to review.
5. Pro early-access sign-ups
If you choose to join the AllCalculators Pro waitlist, we collect the name, email address, and optional company name you enter, the name of the calculator you were using, and the date you signed up. Your calculator inputs and results are not sent.
We use these details only to tell you about AllCalculators Pro and related updates. They are stored in our customer relationship management (CRM) system operated by Just4Marketing, and we do not sell them. You can unsubscribe at any time, or ask us to see or delete your details through our Contact Us page.
6. Children's privacy
This Site is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will take steps to delete it.
7. Data security
We take reasonable measures to protect the limited technical information described above. However, no method of transmission over the internet is completely secure, and we cannot guarantee absolute security.
8. Changes to this policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the Site after changes are posted constitutes acceptance of the revised policy.
