Privacy
This page describes what actually happens, not what a template says usually happens. If a sentence here is not technically true of the shipped site, it is a bug.
The short version
DetectMark never receives the text you paste or the images you drop. There is no account, no upload endpoint, and no database. The scanning and cleaning code runs in your browser tab, on your device, and the results never leave it.
What happens to your content
Text you paste stays in the page's memory for as long as the tab is open. It is not written to disk, not stored in your browser's local storage, and not transmitted anywhere.
Images you select are read as a local file object. Parsing, metadata extraction and cleanup all happen in the tab, and a cleaned export is generated locally and handed to your browser's download mechanism.
Closing or reloading the tab discards everything. There is nothing to delete afterwards, because nothing was kept.
What "0 B uploaded" means
It means precisely this: zero bytes of your text or your image have been sent to DetectMark or to any third party during the scan.
It does not mean the page made no network requests at all. The browser loads the page's HTML, JavaScript, CSS and font files like any website, and the Image tab additionally loads the Content Credentials module and its WebAssembly file the first time you use it. Those files are served from this domain. None of them carry your content in either direction.
Cookies, storage and analytics
DetectMark sets no cookies. It writes nothing to local storage, session storage or IndexedDB. The site's own code ships no analytics script, no tag manager, no session replay, and no fingerprinting. One measurement layer exists at the hosting level: Cloudflare's cookieless Web Analytics beacon, injected by the host into pages it serves. It records page-load timing, not page content. It sets no cookies, does no cross-site tracking, and cannot see what you paste or scan, which never leaves your device anyway. That is the whole list. Nothing on this site can read or transmit your content.
Hosting
The site is served by Cloudflare as static files. Like any host, Cloudflare processes the network requests needed to deliver a page and may retain standard server-side request records, such as an IP address, a user agent and a requested path, as part of operating its network. That is request-level infrastructure data about page loads, and it is separate from anything you paste or drop into the tool.
Advertising
No advertising is served today. The layout reserves places where an ad could go, and with no ad provider configured those slots render at zero height with no request made.
If advertising is ever enabled, this page will name the network and describe what it sets before it goes live.
External verification
Some watermarks can only be verified by the provider that created them. If DetectMark ever offers such a check, it will require an explicit click, state the exact payload and the exact destination first, and never run automatically. No provider detection API is publicly available today, so no such request can currently be made.
Children
DetectMark is a general-purpose utility with no account system and collects no personal information from anyone, including children.
