    "text": "Based on the official Claude Code documentation, here's what you need to know about session history retention:\n\n## Session History Retention Policy\n\n**Yes, session history is automatically deleted, but the timeline depends on your account type:**\n\n**Consumer users (Free, Pro, Max plans):**\n- If you allow data use for model improvement: 5-year retention period\n- If you don't allow data use for model improvement: **30-day retention period**\n\n**Commercial users (Team, Enterprise, API):**\n- Standard: **30-day retention period**\n- Zero data retention: Available with appropriately configured API keys (no server-side storage)\n- Local caching: Your Claude Code client may cache sessions locally for up to 30 days for session resumption (configurable)\n\n## Key Points\n\n1. **30-day automatic deletion** is the default for most users who don't opt into data improvement or who are commercial users\n2. You can change your privacy settings at any time at [claude.ai/settings/data-privacy-controls](https://claude.ai/settings/data-privacy-controls)\n3. **Local session files** stored on your machine (like the `.claude/projects/` directory) are separate from cloud retention and aren't automatically deleted\n4. If you use the `/bug` command to send feedback, that transcript is retained for 5 years\n\nSince your setup logs session timestamps to `.claude/session-timestamps.log`, you might also want to periodically clean up old local session JSONL files if you want to manage your own storage."

    "text": "Perfect. Now I have comprehensive information. Here's the answer:\n\n## The Claim: TRUE (with important clarifications)\n\nYes, Claude Code does automatically delete local session files after 30 days—but this applies to **specific circumstances** and is **configurable**.\n\n### What Actually Happens\n\nClaude Code automatically cleans up local session files (`.jsonl` files in `~/.claude/projects/`) based on a configurable retention period. The default cleanup period is **30 days**, calculated from the last activity date of each session.\n\nHowever, this is important to understand:\n\n1. **Server-side vs. local:** The 30-day retention you might read about in the official data usage documentation refers primarily to server-side data retention for your account type. Local file cleanup is a separate feature.\n\n2. **The local cleanup is configurable:** This is the key detail. You can disable or extend this behavior entirely by adding this to your `~/.claude/settings.json`:\n\n```json\n{\n  \"cleanupPeriodDays\": 99999\n}\n```\n\nThis extends the retention to effectively unlimited (99,999 days). You can set it to any value you prefer.\n\n3. **Not automatic deletion \"on startup\"—it's time-based cleanup:** Claude Code doesn't necessarily delete them when the application starts up. Rather, it removes session files that haven't been used within the cleanup period as part of its maintenance routine.\n\n### Bottom Line\n\nThe statement is **essentially true** but incomplete. Yes, local sessions are deleted after 30 days by default, but:\n- This is configurable via `cleanupPeriodDays`\n- It's based on last activity date, not absolute creation date\n- You can extend or disable it indefinitely if desired\n\nYour custom settings.json doesn't currently have this configured, so you're using the default 30-day cleanup. If you want to preserve your session files longer, add the `cleanupPeriodDays` setting shown above.\n\nSources:\n- [Claude Code Data Usage Documentation](https://code.claude.com/docs/en/data-usage.md)\n- [Claude Code GitHub Issue #4172: Disable auto-deletion of past conversations](https://github.com/anthropics/claude-code/issues/4172)\n- [Don't let Claude Code delete your session logs](https://simonwillison.net/2025/Oct/22/claude-code-logs/)"
