It's quite misleading, actually. GBoard uses Federated Learning [0] so that models are trained locally on the device and keywords are not sent to the central server. Both Google and iOS use Federated Learning, Federated Evaluation & Tuning, Differential Privacy, and other privacy-preserving AI techniques and/or on-device ML to avoid sending user data to the server. Both have done so publicly since 2017 and have published many papers and talks on the subject. 0: https://arxiv.org/abs/1602.05629 https://arxiv.org/abs/1602.05629
