I don't know about datadog, but they have a flag on claude code to disable telemetry and you can also override the base url to have it point to your own reverse proxy, for example I use Tailscale Aperture which lets me inspect everything and I highly recommend
There's all kinds of telemetry being collected and sent to data brokers, for ad targeting (not directly through Anthropic but third-parties), etc. See this study led by IMDEA Networks in Europe: https://leakylm.github.io/
> The study identifies three main issues: the exposure of conversation permalinks to third-party trackers; the ability to link these interactions to user identities through tracking mechanisms; and the presence of privacy controls and policies that may not accurately reflect actual data flows.
> One of the main findings is the potential transmission of information related to user conversations, such as chat titles, URLs (permalinks), or associated metadata, to third-party trackers such as Meta or Google, along with cookies and other identifiers.
> The study also identifies mechanisms that could enable linking activity in AI systems to real user identities. The combination of identifiers such as cookies (commonly used in tracking services), hashed email addresses, and server-side tracking techniques could facilitate the creation of persistent profiles and user re-identification.
