Our Privacy Commitment
Time Duration Calculator is built with privacy at its core. Here's exactly what we do — and don't do — with your data.
No Data Collection
We do not collect, store, or transmit any personal information. Your input values never leave your device.
No Analytics Cookies
We don't use Google Analytics, Meta Pixel, or any third-party tracking scripts. Zero cookies are set for analytics purposes.
Browser-Only Processing
Every calculation runs 100% in your browser using JavaScript. No server-side calls, no API endpoints, no cloud processing.
No Third-Party Data Sharing
Since we collect nothing, there's nothing to share. We have no advertisers, no data brokers, and no third-party partnerships for user data.
Information We Collect
Time Duration Calculator does not collect any personal data. Specifically:
- We do not require account registration or sign-up
- We do not collect names, email addresses, or contact information through the calculator
- We do not store your calculation inputs or results
- We do not use cookies for tracking or analytics
- We do not use fingerprinting or any other identification techniques
If you contact us via our Contact page, we will receive the information you voluntarily provide (such as your name and email address) solely to respond to your inquiry.
How Our Tools Work
All time calculations are performed entirely within your web browser using client-side JavaScript. This means:
- Your input data (times, dates, durations) is processed locally on your device
- No calculation data is transmitted to our servers or any third party
- When you close or refresh the page, all input data is discarded
- We have no technical capability to access your calculation data
Cookies & Local Storage
We may use minimal local storage (not cookies) for:
- Language preferences — to remember your selected language across visits
- Theme preferences — to remember any display settings you configure
This data is stored entirely in your browser's local storage and is never sent to our servers. You can clear this data at any time through your browser settings.
We do not use tracking cookies, advertising cookies, or any third-party cookies.
Third-Party Services
Our website uses the following third-party services:
- Google Fonts — to serve typography (Bodoni Moda and Sora). Google may log standard access data (IP address, browser type). See Google's Privacy Policy.
- Vercel — our hosting provider, which may collect standard server logs (IP addresses, access times). See Vercel's Privacy Policy.
We do not use any advertising networks, social media tracking pixels, or behavioral analytics services.
Children's Privacy
Time Duration Calculator is a general-purpose utility tool that does not knowingly collect information from children under 13. Since we do not collect personal information from anyone, we are inherently compliant with COPPA (Children's Online Privacy Protection Act) and similar regulations.
Data Security
Our website is served over HTTPS to ensure secure communication between your browser and our servers. Since we do not collect or store personal data, the primary security measures are focused on:
- Secure SSL/TLS encryption for all page loads
- Regular security updates to our hosting infrastructure
- Clean, dependency-minimal codebase to reduce attack surface
Your Rights
Under GDPR, CCPA, and other privacy regulations, you have certain rights regarding your personal data. Since we do not collect personal data through our calculator tools, most data subject rights (access, deletion, portability) are inherently satisfied.
If you have contacted us and wish to have your communication records deleted, please email us at contact@timedurationcalculator.com.
Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with a revised "Last Updated" date. We encourage you to review this policy periodically.
Material changes that affect your rights will be prominently noted on our website.
