Specific mentions include Hungarian domestic intelligence, national police in El Salvador, and multiple US law enforcement departments. potatoguy stated the data reveals "highly sensitive details about an individual's habits, interests, and nearly every aspect of their private life." Further pointing out lemmydev2 noted the technology moved from the Israeli firm Cobwebs Technologies to its successor, Penlink, following a July 2023 merger.
