Data sharing prompt appears every session despite account setting being disabled

Description

The data sharing prompt ("Help improve Claude") appears at the start of every new Claude Code session, even though I have already disabled data sharing in my Claude account settings.

Steps to Reproduce

1. Go to https://claude.ai/settings/data-privacy-controls
2. Disable the "Help improve Claude" / model improvement setting
3. Start a new Claude Code session
4. The prompt still appears asking about data sharing
5. Select "No"
6. Start another new session
7. The prompt appears again

Expected Behavior

Once the data sharing preference is disabled in my Claude account settings, Claude Code should respect that preference and not prompt me again.

Actual Behavior

The prompt appears every single session, regardless of my account-level privacy settings being configured to opt out.

Environment

• OS: Windows
• Claude Code version: Latest (auto-updated)
• Account type: Pro subscription with data sharing disabled

Suggested Fix

Either:

1. Sync and respect the account-level privacy setting properly, or
2. Provide a local configuration option (e.g., in .claude.json or settings) to permanently disable this prompt
