Privacy Policy

Information We Collect

Calculator usage: All time calculations are performed locally in your web browser using JavaScript. No calculation inputs, results, or related data are transmitted to or stored on our servers. Your calculation data remains entirely on your device.

Automatically collected information: When you visit our site, our web servers and third-party services may automatically collect certain technical data, including your IP address, browser type and version, device type and operating system, pages visited and time spent on each page, referring URL (the page that linked you to our site), and approximate geographic location based on IP address.

Cookies: We use three categories of cookies on our site:

How We Use Your Information

We use the information we collect for the following purposes:

• Website analytics and improvement: We analyze aggregate usage data to understand which pages and tools are most popular, identify technical issues, and improve the user experience across our calculators and resource guides.
• Serving relevant advertisements: We display ads through third-party networks to support the free availability of our tools. Information collected by ad networks may be used to show you ads relevant to your interests.
• Ensuring site security: We monitor traffic patterns to detect and prevent abuse, unauthorized access, and other malicious activity.

Advertising

We display advertisements through third-party ad networks, including Google AdSense, to support the ongoing development and free availability of our time calculation tools.

These ad networks may use cookies, web beacons, and similar tracking technologies to collect information about your visits to our site and other websites. This information may be used to serve advertisements tailored to your interests (personalized ads) or to serve general, non-personalized ads based on the content of the page you are viewing.

Google, as a third-party vendor, uses cookies (including the DoubleClick cookie) to serve ads on our site. You can learn more about how Google uses advertising cookies by visiting Google's Advertising Policies.

How to opt out of personalized advertising:

• Manage your Google ad personalization preferences through My Ad Center.
• Opt out of interest-based advertising from participating companies at the Digital Advertising Alliance opt-out page.
• Visit the Network Advertising Initiative opt-out page for additional options.

Please note that opting out of personalized ads does not remove advertising from our site — you will still see non-personalized ads.

Cookies and Tracking Technologies

Essential cookies are necessary for core site functionality. These cannot be disabled without affecting your ability to use certain features of the site.

Analytics cookies (such as those set by Google Analytics) help us measure site traffic and understand user behavior in aggregate. These cookies do not identify you personally.

Advertising cookies (such as those set by Google AdSense and partner ad networks) enable the delivery and measurement of advertisements on our site. These may track your browsing activity across multiple websites.

How to disable cookies: Most web browsers allow you to control cookies through their settings. You can typically find these options in your browser's "Privacy" or "Security" settings. Common browsers provide instructions here: Chrome, Firefox, Safari, and Edge.

Please note that disabling analytics or advertising cookies may reduce the relevance of ads you see and will limit our ability to understand and improve site usage. Disabling essential cookies may affect site functionality.

Third-Party Services

We use the following third-party services that may collect data when you visit our site:

• Google Analytics — for measuring site traffic and usage patterns. See the Google Privacy Policy.
• Google AdSense — for displaying advertisements. See Google's Ad Policies.
• Content Delivery Network (CDN) providers — for delivering site assets quickly and reliably. These providers may log basic request data such as IP addresses for security and performance purposes.

We do not control the privacy practices of these third-party services. We encourage you to review their respective privacy policies to understand how they handle your information.

Data Retention

Analytics data is retained in aggregate form for up to 14 months, consistent with Google Analytics 4 default retention limits. After this period, user-level and event-level data is automatically deleted. Aggregated standard report data may be retained longer for trend analysis.

Server log data (including IP addresses) is retained for up to 90 days for security monitoring purposes and then deleted.

No personal calculation data is stored. Because all calculator operations run in your browser, we have no calculation data to retain or delete.
