The company said "certain data" of mobile users such as country code may have been shared with advertising partners since May 2018 "even if you didn't give us permission to do so."

Twitter also said since September 2018 it may have shown ads "based on inferences" made about users' devices, without consent.

The issues were "fixed on August 5" and Twitter says it  is conducting an investigation into who may have been impacted.
