Privacy Policy
Last updated: September 2, 2026. This website operates strictly as a client-side static utility that does not collect, monitor, sell, or store your personal information.
1. Overview & Commitment
Time Calculator (calculadoradetempo.com) is an independent static utility project developed by echoarc. We believe privacy is a fundamental human right. Our website is built with a zero-data-collection philosophy: we do not require account registration, we do not employ profiling trackers, and we never collect, store, or sell any personal data.
2. Information We Do Not Collect
Because this is a completely static website with no user accounts or server databases, we do not collect:
- Personal Identifying Information: We do not collect names, email addresses, phone numbers, postal addresses, or government identification numbers.
- Financial Information: All tools on this site are 100% free. We do not collect credit card numbers, billing information, or bank details.
- User Calculations & Inputs: Any time entries, work hours, shifts, pay rates, or calculation logs you enter into the calculators remain strictly on your local device.
- Biometric or Location Data: We do not track or request your precise GPS geolocation or biometric identifiers.
3. Client-Side & Local Processing
All mathematical computations—including time addition, time subtraction, decimal hour conversions, work shift duration tracking, and overtime estimation—are executed entirely in your browser using client-side JavaScript. No calculation payload is ever sent over the internet or transmitted to remote servers. If you disconnect from the internet after loading the page, the calculator functions completely offline.
4. Local Storage & Preferences
Our website may use your web browser's native localStorage strictly to store your interface theme preference (Light Mode vs. Dark Mode). This data is stored solely on your physical device, is never transmitted to us or any third party, and can be deleted at any time by clearing your browser's site data or cache.
5. Cookies and Tracking Technologies
We do not use tracking cookies, advertising pixels, cross-site beacons, or digital fingerprinting technologies. We do not partner with third-party data brokers or behavioral advertising networks.
6. Third-Party Assets & Content Delivery Networks (CDNs)
To ensure optimal performance and security, this website may load static font assets from Google Fonts (fonts.googleapis.com) and may be hosted via modern content delivery networks (CDNs). When your browser requests static assets (like web fonts or stylesheets), the CDN servers automatically receive standard technical transmission logs (such as your IP address and browser User-Agent header) as required to deliver web files. These logs are managed per the respective CDN provider's standard security policies.
7. External Links
Our educational guides and FAQ sections may provide links to external websites, such as government labor standards or documentation. We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party websites or services.
8. Children's Privacy
Our service is a general-audience educational and mathematical utility. We do not knowingly collect or solicit any personal information from children under the age of 13.
9. Changes to This Policy
We reserve the right to revise or update this Privacy Policy from time to time. Any modifications will be posted directly to this page with an updated "Last updated" date. Since we do not collect contact details, we encourage users to periodically review this page.
