Your file stays yours.

Updated November 12, 2026.

Local file processing

CommaMend reads and processes selected CSV files in your browser. File contents, edits, and reports are not uploaded to our servers. Closing or refreshing the page clears the working session. Downloads stay on your device.

CSV URL imports

When you enter a URL, your browser connects directly to that source. The source receives the request and your IP address under its own privacy practices. It must permit cross-origin browser requests. We do not use a proxy.

Hosting and analytics

There is no application analytics, advertising, account system, or tracking cookie. The hosting provider may process ordinary network information, such as IP addresses and requested page URLs, to deliver the website. Locally imported file contents are not part of those requests. Fonts are served with the site.

Advertising and your choices

This release does not load advertising scripts or set advertising cookies. If advertising is introduced, this notice will identify the providers and applicable privacy choices before ad serving is activated.

Saving, copying, and sharing

Save options use your browser’s download or file picker features. Copy CSV writes the text to your clipboard when permitted, or lets you select it for manual copying. If you explicitly choose Save or Share CSV, your browser passes the file to the app you select. That app may store or transmit the file under its own privacy settings. CommaMend does not upload the file to perform these actions.

Contact and privacy requests

For privacy questions, email team@klauzi.com or use the contact page. Sending an email shares its contents with the recipient and email providers. Do not attach sensitive CSV files. We can only respond about information actually received through those channels; locally processed CSV contents are not held by this website.

You control your data

Keep backups of important files. CommaMend does not alter the original file on your device. Use the download action to save a new version.
