Privacy Policy

Last updated: January 2025

Overview

At JS Tools, your privacy is our top priority. We've designed our tools to process data entirely in your browser - your data never leaves your device.

Data Processing

All data processing happens locally. When you use our tools to format, validate, or convert data:

  • Your input data is processed entirely in your browser using JavaScript
  • No data is sent to our servers or any third-party servers
  • No data is stored anywhere except in your browser's local storage (for preferences)
  • Your data remains completely private and under your control

Local Storage

We use browser local storage to save:

  • Your theme preference (light/dark mode)
  • Recently used tools for quick access
  • Usage statistics for the "Most Used" section
  • Editor content (optional, to restore your work)

You can clear this data at any time through your browser settings. This data is never sent to our servers.

Analytics

We use Google Analytics to understand how our tools are used and to improve the user experience. Analytics data is anonymized and does not include any of the data you process with our tools.

Analytics may collect:

  • Pages visited
  • Browser type and version
  • Device type
  • Geographic region (country level)
  • Referral source

Cookies

We use minimal cookies for analytics purposes only. No cookies are used to track your personal information or the data you process.

Third-Party Services

Our website may load resources from third-party CDNs (Content Delivery Networks) to deliver the application efficiently. These services may log standard web access data (IP address, browser type, etc.) according to their own privacy policies.

Security

We use HTTPS to encrypt all traffic between your browser and our website. Since all data processing happens locally, your sensitive data is never transmitted over the network.

Children's Privacy

Our service is intended for general audiences and does not knowingly collect personal information from children under 13.

Changes to This Policy

We may update this privacy policy from time to time. We will notify you of any changes by posting the new privacy policy on this page and updating the "Last updated" date.
