Privacy Policy

Introduction

At Data Cleansing Application, we take your privacy seriously. This Privacy Policy explains how we handle your data when you use our service.

Data Processing

Client-Side Processing Only

The Data Cleansing Application processes all files entirely in your web browser using JavaScript. This means:

• Your files are never uploaded to our servers
• Your data never leaves your computer
• We have no access to your files or their contents
• No data is stored or transmitted anywhere

Temporary Storage

When you upload a file:

• The file is temporarily held in your browser's memory during processing
• Once processing is complete and you download the cleansed file, the data is cleared from memory
• Closing the browser tab or window immediately clears all data
• No data persists after you leave the application

Information We Collect

File Data

We do not collect, store, or have access to any files you upload or process through the application.

Usage Analytics

We may collect anonymous usage statistics through standard web analytics tools, including:

• Page views and navigation patterns
• Browser type and version
• Device type (desktop, mobile, tablet)
• General geographic location (country/region level only)
• Time spent on the application

This information is collected anonymously and cannot be used to identify individual users.

You can disable cookies in your browser settings, though this may affect some functionality.

Third-Party Services

Firebase Hosting

The application is hosted on Firebase Hosting (Google Cloud Platform). Firebase may collect standard server logs including IP addresses and access times. These logs are used for security and performance monitoring only.

Google AdSense

We use Google AdSense to display advertisements. Google may use cookies and similar technologies to:

• Serve relevant advertisements
• Measure ad performance
• Prevent fraud

For more information, see Google's Privacy Policy.

External Libraries

The application uses the following JavaScript libraries for file processing:

• Papa Parse: For CSV parsing (runs entirely in your browser)
• SheetJS: For Excel file handling (runs entirely in your browser)

These libraries process data locally in your browser and do not transmit data externally.

Data Security

Since all processing happens in your browser and no data is transmitted to servers:

• Your data is as secure as your local computer
• We recommend using the application on trusted devices only
• Ensure your browser is up to date for the latest security features
• Use HTTPS (the application is served over secure connections)

Your Rights

Since we do not collect or store your file data, there is no personal data for us to manage. However, you have the right to:

• Use the application without providing any personal information
• Opt out of analytics cookies through your browser settings
• Request information about any analytics data we may have collected

Children's Privacy

The Data Cleansing Application does not knowingly collect any information from children under 13 years of age. The service is designed for general use and does not target children.

International Users

The application is accessible worldwide. Since all processing happens in your browser, your data remains in your jurisdiction and is not transferred internationally.

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last Updated" date. We encourage you to review this policy periodically.
