Posture
Routes only to endpoints OpenRouter marks as zero-retention. OpenRouter itself does not store prompts unless you opt in. Still third-party plaintext.
ZDR path
None recorded.
Carve-outs
implicit prompt cache is not treated as retention; plugins and web search keep their own policies; ZDR is claimed by upstream, not verified here
