Responding to a post suggesting that Claude Code’s next-message suggestions might collect user-preference training signals, the feature’s developer explicitly said they are not used to collect preference signals. Acceptance counts are used to assess usefulness, with the feature intended to maintain workflow and help users return to sessions. Gray suggestion text can be overwritten or disabled in settings. The cited blog returned a 404, so the introductory page was compared with the developer’s public comments. The original speculation must therefore be distinguished from the response denying it, and that comment alone cannot establish the service’s overall data policy.
