This policy explains what information Calc Hives collects, how it is used, and the choices you have. Your privacy matters to us, and we keep data collection to a minimum.
Last updated: August 9, 2026
This Privacy Policy describes how Calc Hives ("we", "us", or "our") handles information when you visit https://calchives.com (the "Site"). By using the Site, you agree to the practices described here. If you do not agree, please discontinue use of the Site.
Our calculators and converters run entirely in your web browser. The numbers and values you type — such as income, loan amounts, weight, height, or measurements — are processed on your device to produce a result. We do not transmit, collect, or store the values you enter into our tools.
If you use our Contact Us form, you may voluntarily provide your name, email address, and a message. We use this only to read and respond to your enquiry. Messages may be delivered through your email application or a third-party form service, and we retain them only as long as needed to address your request.
Like most websites, our hosting provider and analytics or advertising partners may automatically receive standard technical information, including your IP address, browser type, device type, operating system, referring page, and the pages you visit. This information helps us keep the Site secure, understand which tools are useful, and improve performance.
A cookie is a small text file stored on your device. We may use cookies and similar technologies (such as browser local storage) to remember preferences, measure traffic, and support advertising where applicable. Some cookies are set by us; others are set by third parties described below.
You can control or delete cookies through your browser settings. Disabling cookies may affect certain features, but the core calculators will continue to work because they run locally in your browser.
We may use privacy-respecting analytics services (for example, Google Analytics) to understand aggregate, anonymised usage — such as which calculators are most popular and how visitors navigate the Site. Analytics providers process this data on our behalf and may set their own cookies. We do not use analytics to identify individual visitors.
To keep Calc Hives free, we may display advertising, including through Google AdSense or other advertising networks. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
The Site may load resources from trusted third parties, such as Google Fonts for typography and a form-handling provider for the contact form. These providers may receive technical request data (such as your IP address) as a normal part of delivering their service. We choose reputable providers and encourage you to review their privacy policies.
We use the limited information we receive to: operate and maintain the Site; respond to your messages; monitor and improve performance and reliability; keep the Site secure and prevent abuse; measure aggregate usage; and, where applicable, display advertising that helps fund the Site. We do not sell your personal information.
Depending on where you live, you may have rights under laws such as the EU/UK General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA), including the right to access, correct, or delete personal information we hold about you, and to object to or restrict certain processing. Because our calculators do not collect the values you enter, most personal data we might hold relates only to messages you choose to send us. To exercise any right, contact us using the details below.
Calc Hives is a general-audience website and is not directed at children under 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided us personal information, please contact us and we will delete it.
We take reasonable technical and organisational measures to protect information against loss, misuse, and unauthorised access. However, no method of transmission or storage over the Internet is completely secure, and we cannot guarantee absolute security. We retain contact messages only for as long as necessary to respond and keep basic records.
The Site is operated for a global audience. If you access it from outside the country where our service providers operate, your information may be processed in other countries whose data-protection laws may differ from those in your location.
We may update this Privacy Policy from time to time to reflect changes in our practices or for legal reasons. When we do, we will revise the "Last updated" date above. We encourage you to review this page periodically.
If you have any questions about this Privacy Policy or how your information is handled, please reach out through our Contact Us page.
