Services you connect yourself (e.g. Google, Gmail, Slack, GitHub, Notion) are authorized by you under your own account and are not Kylon subprocessors. Likewise, third-party tools Kylon can call on your behalf through its integration proxy (e.g. Apollo and similar data services) act only when you direct them and are not Kylon subprocessors. We update this list as subprocessors change.
