Ukraine (country) and Ukrainian (language) are both supported. We're cleaning up the way the languages and countries are listed, but if you re-install, you will find Ukraine towards the top of the list (just above United Kingdom).

Not sure what happened here - versions of the software above 1.2.20 should accept all postcodes worldwide. We'll report this as a bug and address it in the next version.

Sorry for the slow reply to this. To reply to your points and hopefully reassure you:

1/ There's no age limitation on the software (but please use a real age so we're able to identify and report on trends in political advertising).

2/ We're interested in people's self-identified political views because it helps observe trends in who's targeting who, and how accurate political advertisers are in reaching people who share their views. E.g. if you report as being left-wing, but see lots of adverts from right-wing parties, there are interesting questions raised about how well campaigns are doing their job.

3/ We don't sell data.

4/ Our campaign is for parties and social media platforms to be more transparent about political advertising and for regulators to respond. Nothing else.

5/ The permissions on the software are broader than we'd like them to be. This is a limitation of the browser extension format. Anyone who wants can review our code on our Github, to confirm that the software only identifies advertising in the feed, much like an adblocker does.

Sorry for the slow reply - we had some early issues with trying to identify different formats of zip-code from around the world, but have now fixed this and the software should work wherever you live.
