It has been tried several times in the past with limited success, but now confidence is high that there is a broadly compatible release of Privoxy for Android devices.

It is available at Sourceforge or here, the project’s mirror site.

This release statically links all dependencies in order to be as compatible as possible, at the cost of raising the binary’s size from ~600K to ~1.1MB; it was considered well worth the size growth¬†in order to be applicable to the widest range of Android devices and versions.

So far Privoxy for Android has been tested on point releases of Android 4 & 5, and on a Samsung tablet, a Samsung Galaxy S4 phone and a Oneplus 2 phone.
