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 inlocalStorageto 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

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 erasure: You may request deletion of your personal data.
- Right to object: You may object to processing of your data for advertising purposes.
