Introduction
DateCalcPro.com ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website and use our professional date and time calculator tools. We believe in transparency and want you to understand exactly how your data is handled when you use our services. By accessing or using DateCalcPro.com, you agree to the terms outlined in this Privacy Policy. If you do not agree with our policies and practices, please do not use our website.
Information We Collect
Calculator Input Data
When you use our date and time calculators, you input various data such as dates, times, and numerical values to perform calculations. This data is processed entirely within your web browser using client-side JavaScript. We do not transmit, store, or record any of your calculator inputs on our servers. Your calculation data never leaves your device. Once you close or refresh the page, all input data is immediately cleared from your browser's temporary memory. This architecture ensures maximum privacy—your personal dates, project timelines, birth dates, work hours, or any other sensitive information you calculate remains completely private to you.
Automatically Collected Information
Like most websites, we automatically collect certain technical information when you visit DateCalcPro.com. This includes your IP address, browser type and version, operating system, device type (desktop, mobile, tablet), referring website URLs, pages you visit on our site, date and time of your visit, and general geographic location (country or city level, not precise location). This information is collected through standard web server logs and is used solely for website analytics, security monitoring, and improving user experience. We use this data to understand how visitors use our site, identify technical issues, prevent abuse, and optimize our calculators for different devices and browsers.
Cookies and Tracking Technologies
DateCalcPro.com may use cookies and similar tracking technologies to enhance your browsing experience. Cookies are small text files stored on your device that help us remember your preferences and understand how you interact with our site. We may use session cookies (which expire when you close your browser) and persistent cookies (which remain on your device until deleted or expired). We also use third-party analytics services such as Google Analytics to help us understand website traffic patterns and user behavior. These services may use cookies to collect anonymous usage data. Additionally, we may display advertisements through Google AdSense or similar advertising networks, which may use cookies to serve relevant ads based on your browsing history across websites. You can control cookie preferences through your browser settings, though disabling cookies may affect certain website functionality.
How We Use Your Information
The limited information we collect is used exclusively for the following purposes: (1) Providing and maintaining our calculator services – ensuring our tools function correctly across different browsers and devices; (2) Website analytics and improvement – understanding which calculators are most popular, how users navigate our site, and where we can improve usability; (3) Security and fraud prevention – monitoring for malicious activity, preventing abuse, and protecting our infrastructure; (4) Legal compliance – meeting legal obligations and responding to lawful requests from authorities when required; and (5) Advertising – displaying relevant advertisements through approved advertising partners to support our free service. We do not sell, rent, or trade your personal information to third parties for their marketing purposes.
Third-Party Services
DateCalcPro.com may utilize third-party service providers to facilitate our website operations, including analytics services (such as Google Analytics), advertising networks (such as Google AdSense), and content delivery networks. These third parties have access only to the information necessary to perform their specific functions and are contractually obligated not to use it for other purposes. These services may collect information governed by their own privacy policies, which we encourage you to review. We carefully select reputable service providers who maintain high privacy and security standards, but we cannot control their data practices and are not responsible for their privacy policies or actions.
Data Security
We implement reasonable technical and organizational security measures to protect information collected through our website from unauthorized access, disclosure, alteration, or destruction. Our website uses HTTPS encryption to secure data transmission between your browser and our servers. However, please understand that no method of internet transmission or electronic storage is 100% secure. While we strive to protect your information using commercially acceptable means, we cannot guarantee absolute security. Since our calculators process all calculation data locally in your browser without server transmission, your sensitive input data benefits from inherent security—it never traverses the internet or reaches our servers, eliminating a major vulnerability point.
Children's Privacy
DateCalcPro.com is a general-audience website providing professional calculation tools. We do not knowingly collect personal information from children under the age of 13. Our services are not directed toward children, and we do not intentionally gather data from users we know to be children. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately, and we will take steps to remove such information from our systems. We are committed to complying with the Children's Online Privacy Protection Act (COPPA) and similar international regulations protecting children's privacy online.
Your Privacy Rights
Depending on your location, you may have certain rights regarding your personal information under privacy laws such as the GDPR (European Union), CCPA (California), or other regional regulations. These rights may include: the right to access information we hold about you; the right to request correction of inaccurate information; the right to request deletion of your information; the right to object to or restrict certain processing activities; and the right to data portability. Since DateCalcPro.com collects minimal personal information (primarily anonymous technical data through server logs and analytics), and does not store your calculator inputs, there is typically little personal data we hold about individual users. However, if you wish to exercise any privacy rights or have questions about data we may have collected, please contact us using the information provided in our Contact Us page.
Changes to This Privacy Policy
We reserve the right to update or modify this Privacy Policy at any time to reflect changes in our practices, technology, legal requirements, or other factors. When we make material changes, we will update the "Last Updated" date at the top of this policy and may provide additional notice through our website. We encourage you to review this Privacy Policy periodically to stay informed about how we protect your information. Your continued use of DateCalcPro.com after any changes to this Privacy Policy constitutes your acceptance of such changes. If you do not agree with the updated policy, please discontinue use of our website.
Contact Information
If you have questions, concerns, or requests regarding this Privacy Policy or our data practices, please contact us through our Contact Us page. We are committed to addressing your privacy concerns promptly and transparently. For general inquiries about how your information is handled, specific requests to exercise privacy rights, or reports of privacy concerns, we will respond within a reasonable timeframe in accordance with applicable law.
