DateTime Calc, operated under SelectMyBlog, respects your digital privacy. Our temporal tools run exclusively in your client browser. We do not store, record, or transmit your calculated dates, personal timestamps, or calendar entries to external servers.

1. Client-Side Processing Architecture

Unlike traditional web applications that transmit form data across public networks to remote web servers, DateTime Calc processes date and time calculations directly within your local browser memory using ECMAScript temporal APIs. Your calendar inputs, target dates, and interval parameters remain strictly on your local device.

2. Web Server Log Files

DateTime Calc follows standard hosting operational procedures by maintaining basic web server log files. These logs record standard technical connection details, including internet protocol (IP) addresses, browser type, internet service provider (ISP), referring and exit pages, platform type, and date/time stamps. These data points analyze aggregate usage trends and administer server security without linking to personally identifiable information.

3. Advertising Cookies & Web Beacons

We may partner with third-party advertising vendors, such as Google AdSense, to support the ongoing maintenance of our free tools. These third parties use cookies to serve relevant advertisements based on prior visits to this website and other internet domains. You can manage or disable personalized advertising cookies through your browser settings or by visiting the Google Advertising Privacy Policy at https://policies.google.com/technologies/ads.

4. Analytics Disclosures

We use Google Analytics and Microsoft Clarity to understand aggregate visitor traffic patterns, popular device screen sizes, and navigational performance. These tools collect anonymized behavioral metrics without capturing personal calendar entries or user identities.
