Virtual practice clients: how your conversations are used
Last updated 9 November 2026
- Virtual practice clients are people made up by Robin. An AI model writes their replies.
- To write each reply, we send the conversation to Anthropic through Vercel’s AI Gateway. Anthropic doesn’t keep it.
- Robin also reads each message you send and gives you feedback on it against the ICF PCC Markers. To do this, we send the conversation to Anthropic in the same way. We store the feedback in Robin, encrypted, and it goes to PostHog with the conversation.
- We also send the full conversation to PostHog, our analytics provider, so that we can read conversations and improve this feature. This is different from the rest of Robin, where we don’t send what you write to PostHog.
- We store the conversation in Robin, encrypted, like your other messages. We keep it until you delete it or your Robin account. When you delete your account, we also ask PostHog to delete its copy.
- Don’t write anything that identifies a real person, such as a client.
- You can stop at any time.
