Your data stays yours.

DataFlow Tools processes your input entirely inside your browser. There is no conversion server, database, analytics, advertising, tracking pixel, or remote font.

What happens to your input?

Text and files stay in page memory. We never send input or output to an API, logs, analytics, or another party. We do not put input into URLs, cookies, local storage, or session storage. Clear the input, close the tab, refresh, or navigate away to discard it. Your browser may keep its own history or clipboard; those are controlled by your browser and operating system.

What does the host receive?

The static host serves the application files and necessarily receives ordinary page requests, including the page URL, IP address, and browser headers. Your conversion content is never included in those requests. A strict production Content Security Policy blocks application network connections.

Files and clipboard

“Open local file” reads a file on your device; it does not upload it. Copy and paste use your browser’s clipboard permission. Downloads are created locally. This application does not send your clipboard or downloaded content anywhere.

Optional support

If a support link is configured, clicking it opens Buy Me a Coffee in a new tab without a referrer. That website has its own privacy policy. No third-party scripts or embeds load here.
