What this site collects, and what it doesn’t.

csvsort is built and operated by Spergs, LLC, a Florida limited liability company. We’re the data controller for everything described below.

Privacy questions, data-access requests, and corrections go to privacy@spergs.com.

Your CSV files never leave your device. Neither csvsort.com nor app.csvsort.com has accounts, forms, cookies, analytics, advertising, or anything loaded from another domain. What we do have is the web server’s request log, described in full below.

The csvsort app at app.csvsort.com is a static JavaScript application. When you open a CSV file in it, the file is read, parsed, sorted and exported entirely inside your browser tab. The contents of your file, its column names, and everything you do with it are never transmitted to us or anyone else.

The app stores nothing on your device: no cookies, no localStorage, no sessionStorage. Close or reload the tab and the file and your changes are gone.

Every time your browser loads a page, script or image from csvsort.com or app.csvsort.com, our web server records:

• Your IP address, and any forwarding header your network adds.
• The time, the address requested (including anything after a ?), the response status and size.
• The page that linked you here (the referrer), and your browser’s user-agent string.

From the IP address we also look up the country and the network operator (ASN) it belongs to, using a database kept on our own servers.

How long it’s kept. Our log system keeps these records for up to one year. A daily archive of them is also kept, with no fixed time limit, on storage we own and in Google Cloud (Cloud Storage and BigQuery), which processes it on our behalf.

What it’s used for. Running and securing the sites (debugging, spotting abuse), rough traffic counts, and building and training our own operations tools on log data. We don’t sell these logs, share them with advertisers or data brokers, or use them to build profiles of visitors.

• The contents of any CSV file you open in the app.
• Column names, sort choices, renames, filters, or any other in-app interaction.
• Email addresses or other identifying information through the sites — there are no forms or accounts.
• Cookies of any kind, first-party or third-party.

If you email us at we@spergs.com, privacy@spergs.com, or security@spergs.com, we’ll have whatever you put in the email: your address, your name if you signed it, and the message. We keep that correspondence as long as it’s useful for answering you.

If we make material changes, we’ll update the “Last updated” date at the top of the page. Continued use of the site after a change means you accept it.
