Privacy Policy

Last Updated: May 23, 2025

1. Introduction

Welcome to NatSheets. We are committed to protecting your privacy and ensuring the security of your data. This Privacy Policy explains how we collect, use, and safeguard your information when you use our service.

NatSheets is designed with privacy as a core principle. Our approach to data processing is fundamentally different from most web applications, as we prioritize keeping your actual data within your browser.

2. Browser-Based Processing

Unlike most data analysis tools, NatSheets processes your spreadsheet data entirely within your browser. This means:

• Your actual spreadsheet data (cell values) never leaves your device
• Analysis operations are performed locally in your browser
• We don't store, access, or transmit the contents of your spreadsheets

This architecture provides an unparalleled level of privacy protection, as your sensitive data never travels over the internet to our servers.

3. Information We Collect

3.1 Metadata

To provide our service, we collect and process only the following metadata about your spreadsheets:

• Column names and headers
• Data types of columns (text, number, date, etc.)
• Structure information (number of sheets, rows, and columns)

This metadata allows our AI to understand the structure of your data without accessing the actual values.

3.2 Account Information

If you create an account, we collect:

• Email address
• Name (optional)
• Password (stored securely as a hash)

3.3 Usage Information

We collect anonymized usage data to improve our service, including:

• Types of analysis performed (without the actual queries or data)
• Features used
• Error occurrences
• Performance metrics

4. How We Use Your Information

We use the collected information for the following purposes:

• To provide and maintain our service
• To improve and optimize our AI capabilities
• To personalize your experience
• To communicate with you about your account or our services
• To detect and prevent errors or service abuse

5. Data Storage

Since your actual spreadsheet data never leaves your browser, we don't store this information. For the information we do collect:

• Account information is stored in our secure database
• Metadata is temporarily processed for analysis but not permanently stored
• Usage information is stored in anonymized form

6. Cookies and Local Storage

We use cookies and local storage for the following purposes:

• To maintain your authentication status
• To store your preferences
• To analyze usage patterns (anonymized)

You can configure your browser to reject cookies, but this may limit functionality.

7. Data Sharing

We do not sell, trade, or rent your personal information to third parties. We may share limited information with:

• Service providers who help us operate our platform
• Legal authorities when required by law

All service providers are bound by confidentiality agreements and data processing restrictions.

8. Security

We implement robust security measures to protect your information:

• All communications are encrypted using TLS/SSL
• Passwords are stored as secure hashes, not plaintext
• Regular security audits and updates
• Strict access controls for our employees

9. Your Rights

You have several rights regarding your personal information:

• Access your personal information
• Correct inaccurate or incomplete information
• Delete your account and associated data
• Export your account information
• Object to certain types of processing

To exercise these rights, please contact us at privacy@natsheets.com.

10. Children's Privacy

Our service is not intended for individuals under 16 years of age. We do not knowingly collect personal information from children under 16. If you believe a child has provided us with personal information, please contact us.

11. Changes to this Policy

We may update this Privacy Policy periodically to reflect changes in our practices or for legal reasons. We will notify you of significant changes by email (for account holders) and by posting a notice on our website.
