Privacy Policy

Privacy-First Philosophy

At DeckTools (accessible from https://decktools.app), our primary commitment is protecting your privacy. Unlike traditional cloud-based utilities, every single tool and calculator on DeckTools executes 100% locally on your computer or mobile device using client-side JavaScript, Canvas, and HTML5 Web APIs.

1. Zero Server-Side Data Collection

When you enter financial figures into our calculators, paste code into our formatters, or upload files into our converters, that data is processed entirely within your local browser sandbox. It is never transmitted, saved, uploaded, or analyzed on any external server.

2. Local Storage and Preferences

We use standard HTML5 LocalStorage solely to remember your chosen theme preference (Dark Mode or Light Mode). No personally identifiable information (PII) is ever written to your local storage or cookies.

3. Anonymous Analytics

We use standard privacy-respecting analytics to measure aggregated website metrics (such as page visits and device screen sizes) to help us improve performance and responsive layout. No user calculation inputs or transformed files are ever recorded.

4. Contact Inquiries

If you contact us via our Contact Form, your submitted name and email address are used solely to reply to your inquiry or feedback. We do not sell, rent, or share contact information with any third-party marketing companies.

5. Questions or Feedback

If you have any questions regarding our Privacy Policy, please reach out directly through our Contact Us page.
