Not sure about captchas but the honeypot filter works fine.

Its open source so there probably is a good level of privacy.

Thanks for the quick response.

Okay, then. I am satisfied with this. Is there a private (preferably FOSS) way through which I can use it on Android?

Isn’t that an AI image generator of some sort? I want something that can help me recognise a (famous) person by taking a picture of them or find the Amazon page of a book through its cover.
