Anthropic has removed a hidden background activity logger from Claude Code after developers flagged a silent process running on their machines that continued transmitting data even when the official opt-out toggle was enabled. The company framed the behavior as a bug and pushed a fix in response to developer complaints.
What developers found
Reports circulated among Claude Code users pointing to a background process running on developer machines with no clear documentation in the product’s privacy notice. The process appeared to log coding-related activity in the background, and users said the official opt-out toggle did not stop it from transmitting data.
How Anthropic responded
Anthropic acknowledged the concern and removed the background logging component. The company framed the behavior as a bug rather than an intentional design choice, and said changes had been pushed to address developer complaints.
Why the disclosure mattered
Coding assistants typically have wide access to local files, terminal commands, and repository contents. When background telemetry runs without an obvious off switch, the trust gap between developers and a vendor widens quickly, especially for teams handling proprietary codebases.
The episode underscores a recurring tension in AI tooling: balancing product analytics with transparent, working privacy controls. Engineers evaluating any AI coding assistant should review what runs locally, what leaves the machine, and whether opt-out settings are actually honored.
