Our Privacy-First Approach

At ExcelDataCleaner, we believe your data is yours. That's why we've built our Excel and CSV cleaning tool to process everything directly in your browser. Your files never leave your device, and we never see or store your spreadsheet data.

What We Don't Collect

• Your spreadsheet files or their contents
• Column names, row data, or any cell values
• File names or metadata from your uploads
• IP addresses or device fingerprints

What We Do Collect

We collect minimal information necessary to provide our service:

• Email address (optional): Only if you choose to save your account or upgrade to Pro
• Usage count: A simple counter to track your 3 free cleanings (stored locally in your browser)
• Payment information: Processed securely by our payment provider (Iyzico) - we never see your card details
• Basic analytics: Anonymous usage statistics to improve the service (e.g., page views, button clicks)

How Your Data is Processed

All file cleaning happens entirely in your browser using JavaScript. When you upload a file:

1. The file is read directly in your browser's memory
2. Cleaning operations are performed locally on your device
3. The cleaned file is generated in your browser
4. You download the result directly - no server upload or storage

Cookies and Local Storage

We use browser local storage to remember your usage count and authentication status. This data stays on your device and is never transmitted to our servers unless you explicitly choose to sync your account.

Third-Party Services

We use the following trusted third-party services:

• Iyzico: For secure payment processing (Pro subscriptions)
• Analytics: For anonymous usage statistics to improve our service

These services have their own privacy policies and security measures.

Your Rights

You have the right to:

• Request deletion of your account and associated data
• Export any data we have about you (email and subscription status)
• Opt out of analytics tracking
• Cancel your subscription at any time

Data Security

Since your files never leave your browser, they're protected by your device's security. Any data we do store (email, subscription status) is encrypted in transit and at rest using industry-standard security practices.

Changes to This Policy

We may update this privacy policy from time to time. We'll notify you of any significant changes by updating the "Last updated" date at the top of this page.
