There's around a dozen issues about this, the oldest one is from a bit under a year ago (though the author marked it closed... prematurely I'd say): https://github.com/anthropics/claude-code/issues/4172 https://github.com/anthropics/claude-code/issues/4172 or this one from December, still open: https://github.com/anthropics/claude-code/issues/9258 https://github.com/anthropics/claude-code/issues/9258 Some more fun facts about this: - it is silent, not announced anywhere, and calls rm on your data - setting the days to zero doesn't disable it, it immediately rm's ALL your chats - even setting it to _something_ big doesn't prevent data loss if you launch Claude Code in some modalities (certain subagents, etc) that don't load this config key but perform deletion anyway (with the 30 day default)
