Twitter apologies for sharing personal data

Twitter said in a statement that it had “recently found issues” where users’ setting choices may not have worked correctly.

Since May 2018, people who clicked or viewed an ad in the Twitter mobile app may have had their data shared with measurement and advertising partners.

That data may have included ‘likes’, ‘retweets’ and country codes.

In addition, since September 2018, Twitter said it might have shown users ads “based on inferences we made about the devices you use, even if you did not give us permission to do so”.

The company said it fixed the problem on 5^th August and that it was still investigating who was affected.
