Privacy Policy

When you perform an age, date difference, or birthday calculation, the input parameters (e.g. birth dates, ages, years) are transmitted to and calculated on our servers in real time to render the results.

No Application Database: yrCalc does not maintain a user account database, does not require registration, and does not permanently store your submitted calculation data in application databases.

Like virtually all web servers, our hosting infrastructure and Content Delivery Network (Cloudflare) automatically collect standard technical access logs. These logs may include:

• Your Internet Protocol (IP) address
• Browser type and user agent
• Date, time, and requested URL path (which may reflect dynamic calculation parameters)
• HTTP response status code and referrer URL

These logs are maintained strictly for network security, DDoS prevention, rate limiting, and technical troubleshooting. They are not used to build personal marketing profiles or identify individuals.

yrCalc may partner with third-party advertising networks, such as Google AdSense, to serve advertisements on the website:

• Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites on the Internet.
• Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visit to our site and/or other sites on the Internet.
• Users may opt out of personalized advertising by visiting Google Ads Settings or www.aboutads.info.
