TheCalcHub.app ("TheCalcHub," "we," "us," or "our") provides free online calculators and conversion tools. This Privacy Policy explains what information we collect, how we use it, and the choices available to you when you use thecalchub.app (the "Site").
Calculator Inputs
The numbers and values you enter into our calculators are processed entirely in your web browser using JavaScript. This data is not transmitted to our servers, stored in a database, or shared with any third party. When you close or refresh the page, your inputs are gone.
Information We Collect Automatically
Like most websites, our hosting provider and analytics tools automatically collect certain information when you visit the Site, including your IP address, browser type and version, device type, operating system, referring URL, pages viewed, and the date and time of your visit. We use this information in aggregate to understand how the Site is used and to maintain its performance and security.
Analytics
We use Google Analytics, loaded through Google Tag Manager, to understand how visitors use the Site. We may also use Microsoft Clarity, which records anonymized session data such as clicks, scrolls, and mouse movements to help us improve page layout and usability. These tools use cookies and similar technologies and may collect information such as your approximate location, derived from your IP address, browser, and device. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.
Advertising
TheCalcHub.app displays advertisements served by third-party advertising networks, including Google AdSense, and may participate in additional advertising programs such as Ezoic or Mediavine as the Site grows. These networks may use cookies, web beacons, and similar technologies to collect information about your visits to this and other websites in order to show you advertisements about goods and services that may interest you.
- Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and other sites on the internet. You can opt out of personalized advertising through Google Ads Settings or the Digital Advertising Alliance's opt-out page at aboutads.info.
- Visitors located in the European Economic Area, the United Kingdom, and Switzerland will be asked for consent to the use of cookies for advertising and analytics purposes before any non-essential cookies are set.
Cookies
Cookies are small text files stored on your device. We use, and allow third parties to use, cookies for the following purposes: essential cookies required for basic Site functionality, analytics cookies that help us understand how visitors use the Site, and advertising cookies that help deliver and measure relevant ads. You can control or delete cookies through your browser settings. Disabling cookies may affect how the Site displays advertisements but will not affect your ability to use our calculators.
Children's Privacy
TheCalcHub.app is not directed to children under the age of 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 so we can remove it.
Data Security
We take reasonable measures to protect the information collected through the Site. However, no method of transmission over the internet or electronic storage is completely secure, and we cannot guarantee absolute security.
Your Rights and Choices
Depending on your location, you may have rights under laws such as the EU General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA), including the right to access, correct, or delete certain information, and the right to opt out of the sale or sharing of personal information for targeted advertising. Because TheCalcHub.app does not require registration and does not collect personal information directly, most of these rights relate to the cookies and analytics described above, which you can manage through your browser and the opt-out tools listed in this policy.
Changes to This Policy
We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page indicates when this policy was last revised. Continued use of the Site after changes are posted constitutes acceptance of the revised policy.
