Hi @bastigruenwald,
Via the web client, depending on the integration type and the user interaction to it, data may be passed through an odrive proxy as opposed to directly from the source. In this case the raw data is being streamed (over end-to-end TLS encrypted transport) from the source to the requesting client/user via the odrive proxy.
This is why you will see downloads coming from proxygen.odrive.com. During this process none of the user data is retained or even cached, beyond the small stream buffer during the real-time streaming.
