Privacy Policy

Last updated: 2026

This page explains what happens to the files you upload, what data we collect, and how advertising on this site works. If anything here is unclear, contact us at kncfilehub@gmail.com.

Files you upload

When you use a tool — splitting, merging, converting, or generating a QR code — the file you provide is uploaded to our storage only to perform that specific task. We do not open, read, or review the contents of your files for any other purpose.

• Uploaded files and the results we generate are automatically deleted from our storage, at the latest within 24 hours, through an automated cleanup process.
• Download links for a completed task expire after a short window (currently 10 minutes) and stop working after that, whether or not the link was used.
• We do not sell, share, or use the contents of your files to train any model or for any purpose beyond completing the task you requested.

Optional accounts

You do not need an account to use any tool on this site. If you choose to create one, we store your username, email address, and a securely hashed version of your password — never your password itself in readable form.

Information collected automatically

Like most websites, our servers log basic technical information for security and reliability — such as IP address, browser type, and request timestamps. This is used to prevent abuse (for example, rate-limiting excessive requests) and is not used to identify individuals.

Advertising and cookies

This site may display advertisements served by Google AdSense and other third-party advertising vendors. These vendors may use cookies and similar technologies to serve ads based on your visits to this site and other sites, and to measure ad performance.

• Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the internet.
• You can opt out of personalized advertising by visiting Google's Ads Settings.
• You can also review or opt out of many third-party vendors' use of cookies for personalized advertising at optout.aboutads.info.

Data security

All uploads and downloads happen over encrypted HTTPS connections. Files are stored using access-controlled cloud storage that isn't publicly browsable.

Your choices

You can use every tool on this site without providing any personal information beyond the file you're processing. If you've created an account and want it deleted, contact us and we'll remove it.

Changes to this policy

If this policy changes in a meaningful way, we'll update the date at the top of this page.
