Privacy Policy

Last Updated: December 21, 2024

Privacy First Promise: Domain Filter Tool processes all files locally in your browser. We do not collect, store, transmit, or have access to any files you upload or process. Your data never leaves your device.

1. Information We Do NOT Collect

Domain Filter Tool is designed with privacy as the core principle. We want to be crystal clear about what we DO NOT collect:

  • Uploaded Files: We never upload, store, or process your files on our servers. All file processing happens entirely in your browser using JavaScript.
  • Domain Lists: We cannot see, access, or store any domain names from your files.
  • Personal Information: We do not collect names, email addresses, phone numbers, or any personally identifiable information.
  • User Accounts: We don't have user accounts, logins, or registration systems.
  • File Content: We have no ability to view or access the content of files you process.

2. How the Tool Works (Technical Explanation)

Understanding how our tool works helps explain our privacy commitment:

  1. Local Processing: When you upload a file, it's read entirely within your web browser using the FileReader API. No data is transmitted to any server.
  2. Browser Memory: The file content is temporarily stored in your browser's memory (RAM) during processing.
  3. Client-Side Operations: All cleaning, filtering, deduplication, and sorting operations are performed by JavaScript running in your browser.
  4. Export Downloads: When you export results, the file is generated locally in your browser and downloaded directly to your device.
  5. Memory Clearing: When you close the browser tab or navigate away, all processed data is immediately cleared from memory.

3. Analytics and Cookies

Anonymous Analytics: We may use privacy-respecting analytics tools (such as Google Analytics with IP anonymization enabled) to understand general usage patterns, such as:

  • Number of visitors to the website
  • Pages viewed and navigation patterns
  • Browser type and device information
  • Geographic region (country level only)
  • Referral sources (how users found our website)

Important: Analytics tools only collect aggregate, anonymous data about website usage. They do NOT track, collect, or have access to any files you upload or domain data you process.

Cookies: We may use essential cookies for website functionality and analytics cookies to understand usage patterns. You can disable cookies in your browser settings, though this may affect analytics collection.

4. Third-Party Services

Google AdSense: We may display advertisements through Google AdSense. Google may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising by visiting Google's Ads Settings.

Important: Third-party advertising services do NOT have access to files you upload or domain data you process through our tool.

5. Data Security

Since we don't collect or store your data, there's no server-side data to secure. However, we take security seriously:

  • HTTPS Encryption: Our website is served over HTTPS to ensure secure communication between your browser and our web server.
  • No Backend Database: We don't have any database storing user data because we don't collect user data.
  • Browser Security: All processing happens within your browser's secure sandbox environment.
  • No File Uploads: Files are never transmitted over the internet to our servers.

6. Your Rights and Control

Because we don't collect personal data or user files, there's no data to access, modify, or delete. You have complete control over your files at all times:

  • Files remain on your device during processing
  • Close the browser tab to clear all processed data from memory
  • No data persists after you leave the website
  • No account deletion required because we don't have accounts

7. Children's Privacy

Our tool is designed for professional use and is not directed at children under 13. We do not knowingly collect personal information from children. Since we don't collect personal information from anyone, this applies universally.

8. International Users

Domain Filter Tool can be used from anywhere in the world. Since all processing happens locally in your browser, your data never crosses international borders or leaves your device. This means we're inherently compliant with international data protection regulations including GDPR, CCPA, and similar laws.

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or legal requirements. Any changes will be posted on this page with an updated "Last Updated" date. We encourage you to review this policy periodically.

Material changes that affect how we handle data will be prominently announced on our website.

Summary

Bottom Line: Domain Filter Tool is built from the ground up with privacy as the core principle. We cannot access your files because they're processed entirely in your browser. We don't collect personal information. We don't store domain data. Your privacy is completely protected by design, not just by policy.
