Privacy Policy.
Last updated: September 24, 2026
1. Privacy-First Architecture
CalculateTimes (calculatetimes.com) is engineered from the ground up as a private scientific utility. We firmly believe that routine mathematical calculations — such as clock additions, employee timesheets, shift punch hours, and calendar dates — are private to you and should never be observed, logged, or monetized by third parties.
2. 100% Client-Side Calculations
All calculations performed on CalculateTimes execute entirely within your web browser’s JavaScript engine on your device. When you enter start and end times, compute hourly wages, add break periods, or select calendar dates, that data exists solely in your device’s volatile memory.
No calculation data is transmitted over the Internet or stored on our servers.
3. Zero Cookies & No Tracking
CalculateTimes does not set or read any HTTP tracking cookies, advertising beacons, canvas fingerprinting scripts, or cross-site surveillance identifiers. We do not partner with ad networks or behavioral data brokers.
4. Local Device Storage (LocalStorage)
To provide a seamless user experience, CalculateTimes saves only your presentation preferences locally on your machine using standard browser localStorage. Specifically:
calculatetimes_theme: Remembers your interface appearance (Light Mode vs. Dark Mode).calculatetimes_format: Remembers your preferred clock notation (12-Hour AM/PM vs. 24-Hour Military).
These items never leave your browser and can be cleared at any time via your browser settings.
5. Hosting Infrastructure & Server Logs
Like all web properties, our static web hosting infrastructure receives standard network transmission data required to deliver requested HTML, CSS, and SVG files (such as your IP address and user-agent string). These temporary diagnostic access logs are discarded routinely and are never correlated with calculation activities.
