Privacy Policy

Last updated: January 1, 2025

ExcelErrorFinder.com ("we", "us", or "our") operates the website located at https://excelerrorfinder.com. This Privacy Policy explains how we collect, use, and protect information when you use our free Excel spreadsheet audit tool.

1. Information We Collect

1a. Files You Upload

We do not collect, store, or transmit any spreadsheet files. All file processing is performed entirely within your web browser using client-side JavaScript. Your Excel files never leave your device and are never sent to our servers. We have no server-side processing of your files whatsoever.

1b. Usage Data

We may collect anonymised, aggregated usage data through Google Analytics (if enabled) such as pages visited, time on site, browser type, and country. This data cannot be used to identify you personally and is used solely to understand how users interact with our tool so we can improve it.

1c. Cookies

We use the following types of cookies:

  • Essential cookies: A single cookie (cookie_consent) stored in localStorage to remember your cookie consent preference. This cookie contains no personal data.
  • Advertising cookies: When you accept cookies, Google AdSense may set third-party cookies on your device to serve personalised advertisements. These cookies are governed by Google's Privacy Policy.
  • Analytics cookies: Google Analytics may set cookies to measure site traffic and usage patterns in an anonymised form.

Google AdSense Disclosure: This site uses Google AdSense to serve advertisements. Third-party vendors, including Google, use cookies to serve ads based on prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet. You may opt out of personalised advertising by visiting Google Ad Settings or aboutads.info.

2. How We Use Information

We use the information we collect to:

  • Display relevant advertisements through Google AdSense (the primary means by which this free service is funded)
  • Analyse aggregated usage patterns to improve the tool's functionality
  • Ensure the website operates correctly and securely

We do not sell, rent, or trade any personal information to third parties.

3. Third-Party Services

We use the following third-party services, each governed by their own privacy policies:

4. GDPR Rights (EEA Residents)

If you are located in the European Economic Area, you have the following rights under the General Data Protection Regulation (GDPR):

  • Right to access: You may request a copy of any personal data we hold about you.
  • Right to rectification: You may request correction of inaccurate data.
  • Right to erasure: You may request deletion of your personal data.
  • Right to object: You may object to processing of your data for advertising purposes.
  • Right to withdraw consent: You may withdraw cookie consent at any time by clearing your browser's localStorage and cookies.

Given that we do not collect personal data beyond what AdSense and Analytics gather, most of these rights are most effectively exercised directly through Google's tools at myaccount.google.com.

5. CCPA Rights (California Residents)

Under the California Consumer Privacy Act (CCPA), California residents have the right to:

  • Know what personal information is collected and how it is used
  • Request deletion of personal information
  • Opt out of the "sale" of personal information (we do not sell personal information)
  • Non-discrimination for exercising CCPA rights

6. Data Retention

We do not store your spreadsheet files. Cookie consent preferences stored in localStorage remain until you clear your browser data. Analytics data, if collected, is retained in an anonymised and aggregated form per Google Analytics' data retention settings.

7. Children's Privacy

ExcelErrorFinder is not directed at children under the age of 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 promptly delete it.

8. Changes to This Policy

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