Privacy Policy

Privacy is the entire point of this tool.

What we don't do

• We don't upload your file to any server — not ours, not a third party's.
• We don't store, log, cache, or analyze your file's contents.
• We don't use cookies, fingerprinting, or session tracking.
• We don't sell, share, or otherwise transmit your data to any third party.
• We don't require an account, email, or signup.

What we do collect

We use Vercel Web Analytics to record anonymous, aggregate page-view metrics — country, device type, browser, and which page was visited. No cookies are set, and no personally identifiable information is collected. This data tells us how many people visit and roughly where they're from, and nothing more.

We do not run any other analytics, advertising pixels, heatmaps, session replay tools, or third-party trackers.

How your file is processed

When you upload a spreadsheet, the file is read by JavaScript code running inside your browser. The cleaning logic runs locally on your device, and the cleaned file is generated and offered as a download — all without sending any data outside your browser.

How to verify

You don't have to take our word for it. Open your browser's DevTools (right-click → Inspect → Network tab), upload a spreadsheet and process it. You will see zero outbound requests carrying your file's contents. The same network tab shows every byte that leaves your browser.

You can also verify by disconnecting your network after the page loads — the tool will continue to work.

Hosting

The site is hosted on Vercel. Standard request logs (IP address, user-agent, timestamp) may be retained briefly by Vercel for operational purposes — these are infrastructure logs, not application data. We have no direct access to your file at any point.

Changes to this policy

If this policy changes, the “Last updated” date at the top will reflect that. The privacy posture won't change without good reason — keeping your data private is the entire premise of the product.
