No, Perchance uses an iframe for sandboxing so the ads/CMP/etc. cannot see any data you input/generate.

Copy-pasting a paragraph from a comment of mine on another thread:

As you probably know, the AI plugin servers are funded by ads. Perchance in general doesn't have any ads, and has always been completely free, but the AI plugins are way too expensive to fund out of my own bank account. So if you're not logged in, you'll see ads on generators that use AI plugins. I figured it's worth mentioning here that unlike basically every other ad-funded site on the internet, Perchance does not trust ads. Perchance has a sand-boxed separation between the actual generator/page contents (which live in a "iframe" - it's basically like a separate browser tab embedded within the page), and the place where ad code runs -- so ads cannot look at your chat/text/image/etc. data in order to guess at more relevant ads. Perchance uses a very reputable advertising company (same one used by Reuters and Aljazeera and several other large companies) so the likelihood of shady ad tech is already extremely low, but there's no need for any trust here, thanks to the sand-boxing that Perchance has. So, in terms of showing you more relevant ads, all they can possibly see is the URL of the page that you're on. That's the only thing that's exposed to ad serving algorithms by visiting a Perchance page, no matter how much information you input into a Perchance generator/page.
