Internet Protocol address – but note that we permanently delete and hash the last portion of your Internet Protocol address before storing it, thus preventing us from having the ability to use it to transmit any information to your device or to otherwise identify you.

And from the privacy policy itself:
> You may opt out of the automatic collection and sharing of Non-Personal Information described above as follows:
> For the BlockSite browser add-on extension:
> By deselecting the checkbox next to the words “Block Adult Sites” which can be found under the Settings tab of the Options page for the BlockSite extension.
