Are you legally covered to sell your app?

Audit this project for legal risks before I start charging users. Check the following, in order of severity. For each one, tell me if it's a problem, why it matters, and what to do about it.

1. PRIVACY POLICY
Does this app have a privacy policy?
- Check for a /privacy, /privacy-policy, or similar route
- Check the footer and signup/login pages for a privacy policy link
- If the app collects any user data (emails, names, usage data, analytics) and has no privacy policy, it's a legal liability in the EU (GDPR) and California (CCPA)

2. CODE OWNERSHIP
Based on this project's framework and dependencies, identify which AI builder tools were likely used to generate it. For each one:
- What are the exact code ownership terms on my current plan? Do I own the code outright?
- Does the tool retain any rights to the generated code?
- Can it use my code for training?
- Are there restrictions on commercial use or resale?
- If terms differ by plan (free vs paid), tell me which plan grants full ownership

3. COPYLEFT DEPENDENCIES
Scan package.json (and any lock files) for dependencies with copyleft licenses:
- GPL, AGPL, LGPL, MPL, or similar licenses
- These licenses can require you to release your entire source code under the same license
- For a commercial product you plan to sell, this means you'd have to give away your code
- Check both direct dependencies and significant transitive dependencies

For each finding, report:
- Number (1, 2, 3...)
- Severity: CRITICAL, HIGH, or OK
- File and line number (if applicable)
- What's wrong (one sentence)
- What could happen if you don't fix it (one sentence)
- How to fix it and what could break (one sentence each)

Sort by severity, then by how fast it could hurt you.

IMPORTANT: This is an audit only. Do NOT modify any code. Report what you find and suggest fixes, but do not apply any changes until I explicitly ask you to.
