Are my files safe?

Yes. Your files are only used to create your result — they’re never shared and never used to train AI.

Can I use text in any language?

Yes. Latin text is added as real text; other scripts (Chinese, Arabic, Cyrillic…) and emoji are drawn as a sharp image so they always display.

Can someone remove the watermark?

It becomes part of every page's content, so it can't simply be switched off — but anyone with a PDF editor could edit it out. Combine it with Protect PDF if that matters.

Does it work on rotated or landscape pages?

Yes. It's placed on the page as you see it in a viewer, so it stays centred and upright on rotated and landscape pages.
