Privacy Policy
Last updated: April 17, 2026
1. Overview
ExcelInsight ("we", "our", or "the Service") is a free, browser-based Excel and CSV analytics tool. This Privacy Policy explains what limited information is collected when you use ExcelInsight and how it is handled.
2. Files & Data You Upload
Files you upload to ExcelInsight (.xlsx, .xls, .csv) are processed entirely within your web browser. Your spreadsheet data is never uploaded to our servers, stored, or shared with any third party. When you close or refresh the page, the file and all derived analysis are discarded from memory.
3. Local Storage
We store small preferences (selected theme and language) in your browser's
localStorage so the site remembers your settings on your next visit. This data never leaves your device.4. Cookies & Analytics
ExcelInsight may use minimal first-party cookies for site functionality. Third-party services described below may set their own cookies.
5. Advertising — Google AdSense
We use Google AdSense to display advertisements. Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this and other websites. You may opt out of personalized advertising by visiting Google Ads Settings or www.aboutads.info.
6. Third-Party Services
Beyond Google AdSense, we do not knowingly share any information with third parties. Hosting infrastructure may collect standard web logs (IP address, user agent, request timestamps) for security and reliability purposes.
7. Children's Privacy
ExcelInsight is not directed to children under 13, and we do not knowingly collect personal information from children.
8. Your Rights
Because we do not collect or store personal data on our servers, there is generally nothing for us to delete on your behalf. You can clear browser-side preferences at any time by clearing your browser's site data.
9. Changes to This Policy
We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page indicates when the latest revision was made.
