Privacy Policy

This privacy policy describes how NERIUM handles user data during the Cerebral Valley plus Anthropic Built with Opus 4.7 hackathon, April 2026. NERIUM is a hackathon submission in test mode at evaluation time.

1. Data We Collect

NERIUM at submission state collects minimal data. If you provide an Anthropic API key under the bring-your-own-key pattern, the key is stored only in browser sessionStorage and never transmitted to NERIUM servers. Account-related data (if you create an account) includes email, hashed password, and Ed25519 public keypair for identity registry. Usage telemetry (page views, feature interactions) is collected via structlog server-side for debugging only.

2. Third-Party Services

NERIUM uses the following third-party services that may collect their own data per their respective policies: Vercel (hosting and CDN), Vercel Postgres via Neon (database), Upstash Redis (cache), Stripe (test mode payment processing, no real money), Resend (transactional email), and Anthropic (Claude API when bring-your-own-key is active). Refer to each provider for their individual privacy policies.

3. Cookies and Local Storage

NERIUM uses sessionStorage to persist a user-provided Anthropic API key during the active session only. No tracking cookies. No advertising cookies. No cross-site tracking.

4. Data Retention

Account data is retained while the account exists. Usage telemetry is retained for 30 days then purged. API keys provided via bring-your-own-key are never persisted server-side.

5. Your Rights

You may request data deletion by opening an issue at the GitHub repository. NERIUM commits to a 30-day response window during the hackathon evaluation period and shorter response times post-launch.

6. Children

NERIUM is not directed at children under 13. We do not knowingly collect data from children.

7. Changes

This privacy policy may be updated post-hackathon. The latest version will always be at this URL.
