No. Everything runs in your browser - your file never leaves your device. How this is verifiable
A watermark like "CONFIDENTIAL", "DRAFT" or a company name makes a document's status clear at a glance and discourages unnoticed reuse. This tool provides a real editor for that: your page appears as a preview, your text sits semi-transparently on top, and you see every change instantly.
Drag the watermark freely with mouse or finger to where you want it - not just into a fixed corner. Rotate it steplessly via the rotate handle (diagonal is common); pick opacity, size and color alongside. For continuous protection enable tile mode, which repeats the text across the whole sheet. If the document has several pages you can page through the preview and, if needed, limit the stamp via the page field.
Everything happens locally in the browser: the page is only rendered for display, the finished PDF is produced with pdf-lib - nothing is uploaded, precisely the key point for confidential documents. Honestly placed, though, a watermark stays a visible marking, not a protection mechanism: it signals status or origin and deters careless forwarding, but it can be removed again with effort and encrypts nothing. If the content should truly be locked, a password via “Protect PDF” belongs with it. The tiled layout makes a clean removal harder, while the freely placed one stays more discreet and barely disturbs reading.

Yes, enter a range like "1-3,5". Empty = all pages.
For an image/logo use "Image watermark in PDF"; this tool does text watermarks.
Not by this tool - the watermark becomes part of the page content.
