Privacy Policy

Effective Date: February 25, 2026

1. Introduction

Welcome to the Simple Date Calculator, a lightweight, browser-based utility for calculating days between dates and adding or subtracting days from any date. We are deeply committed to your privacy. This tool operates entirely client-side using only JavaScript and the browser's native Date API. Because of this design, we collect, store, transmit, or process absolutely no personal data or user input. This Privacy Policy explains our zero-collection approach in clear terms.

2. Information We Do Not Collect

We do not collect any information from you, including:

  • Personal Identifiable Information — names, emails, phone numbers, addresses, or any other identifying details.
  • Usage or Technical Data — IP addresses, browser fingerprints, device types, screen resolution, or location.
  • Input Data — any dates you enter, day counts, or calculation results remain exclusively in your browser memory and are never sent anywhere.
  • Analytics or Tracking Data — we do not use Google Analytics, Matomo, cookies, pixels, beacons, or any third-party tracking service.

All processing happens locally in your browser. Once you close or refresh the page, no trace of your activity remains with us.

3. How the Tool Operates

When you use the Simple Date Calculator:

  • You enter dates and numbers directly into form fields.
  • All calculations are performed using JavaScript's built-in Date object.
  • Results are displayed instantly on the same page.
  • No network requests are made except for loading static assets (HTML, CSS, JS) from the hosting server or CDN.
  • Any temporary values (e.g., form inputs) exist only in browser memory or session storage (if you refresh) and are never persisted or transmitted.

4. Third-Party Services & Hosting

The site is statically hosted (e.g., on GitHub Pages or similar). We do not integrate advertising, analytics, or any data-collecting third-party scripts. All libraries (if any) are either bundled or loaded from trusted CDNs without tracking capabilities.

5. Cookies and Similar Technologies

We use no cookies, localStorage (beyond possible temporary form persistence by the browser), sessionStorage for tracking, or any other persistent identifier. Your visit is completely stateless from our perspective.

6. Children's Privacy

This tool is not directed at children under 13. We do not knowingly collect data from children. If you believe a child has used the service, please contact us.

7. Changes to This Policy

We may revise this Privacy Policy occasionally. Updates will appear here with a new effective date. Continued use after changes constitutes acceptance.

8. Contact

For questions about this policy, reach out via the project's GitHub repository issues (if applicable) or the contact method listed on the site.

By using the Simple Date Calculator you acknowledge and accept this zero-data-collection privacy model. Your dates and calculations stay yours alone.
