Privacy Policy

Last updated: January 1, 2026

This Privacy Policy describes how Data File Tool ("we," "us," or "our") collects, uses, and shares information when you visit https://datafiletool.com and use our browser-based CSV tools.

Your Files Stay on Your Device

Data File Tool processes all CSV and data files locally in your web browser. We do not upload, store, transmit, or have access to any files you process using our tools. Your file contents never leave your device and are never sent to our servers or any third party.

Information We Collect

We collect minimal information to operate and improve the website:

  • Usage analytics: If enabled, we use Google Analytics to collect anonymous usage data such as pages visited, referral sources, browser type, and general geographic region. This data does not include file contents or personally identifiable information from your CSV files.
  • Advertising data: If we display ads through Google AdSense, Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this site or other websites. You can opt out of personalized advertising by visiting Google Ads Settings.
  • Theme preference: We store your light/dark theme choice in your browser's localStorage. This data stays on your device and is not transmitted to us.

We do not require account registration and do not collect names, email addresses, or payment information through our tools.

Cookies and Similar Technologies

We and our third-party partners may use cookies, web beacons, and similar technologies to:

  • Remember your display preferences (theme)
  • Measure site traffic and tool usage (Google Analytics)
  • Deliver and measure advertisements (Google AdSense, if enabled)

You can control cookies through your browser settings. Disabling cookies may affect certain features but will not affect the core CSV processing tools, which run entirely in your browser.

Third-Party Services

We may use the following third-party services:

These services have their own privacy policies governing how they handle data.

Children's Privacy

Our services are not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it.

Your Rights

Depending on your location, you may have rights to access, correct, or delete personal data we hold about you. Because we do not collect file contents or require accounts, the personal data we process is limited. To exercise your rights or ask questions, contact us at the email below.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the site after changes constitutes acceptance of the revised policy.
