Privacy Policy

Develop21 LLC, 85 Red Hill Road, Princeton, NJ 08540
Effective Date: March 24, 2026 | Last Updated: March 25, 2026

This Privacy Policy describes how Develop21 LLC collects, uses, stores, and protects your personal information when you use our AI-powered advisory platform at app.develop21.ai, our browser extension, and any related services.

1. Eligibility

The Service is available only to individuals aged 18 or older. We enforce this by requiring a valid credit card at account creation. If we learn that we have collected information from a person under 18, we will delete that information and terminate the account.

2. Information We Collect

Account Information: Name, email, password (stored as a cryptographic hash), and payment information (processed by Stripe).

Career and Advisory Data: Resumes, job preferences, salary expectations, work experience, career goals, and responses to AI coaching exercises. We treat all career and conversation data as sensitive personal information with heightened protections (see Section 6).

Conversation Data: The full text of your conversations with AI personas, plus memory summaries generated by our multi-layer memory system. Each product's conversations are isolated from other products.

Browser Extension: When actively triggered, the extension captures visible page content and sends it to our servers for processing.

Usage Data: Device type, browser, IP address, pages visited, features used, error logs, and performance data.

3. How We Use Your Information

To operate the Service, process payments, improve features through anonymized analytics, provide support, prevent fraud, and comply with applicable laws.

4. How We Share Your Information

We do not sell your personal data to third parties.

We share data only with service providers necessary to operate the Service:

Anthropic — AI conversation processing. Your data is not used to train their models.

Voyage AI — Text embeddings for memory retrieval. These are numerical representations that cannot be reversed into original text.

Supabase — Database hosting and authentication. Data encrypted in accordance with Section 6.

Stripe — Payment processing. We never store or see your full card number.

5. Payment and Billing

All payment processing is handled by Stripe. We receive only a tokenized reference to your payment method. Billing records (amounts, dates, tier) are retained for 12 months after account deletion for accounting compliance.

6. Data Security

Encryption at Rest: All conversation content, memory summaries, and uploaded documents are encrypted using AES-256-GCM.

Encryption in Transit: All data transmitted between your browser and our servers uses TLS 1.2 or higher.

Access Controls: Administrative access to your conversation content requires your explicit consent (see Section 7).

While we implement industry-standard security measures, no system is completely secure. We commit to promptly notifying affected users in the event of a data breach.

7. Consent-Based Support Access

Our support team cannot view your conversations by default. If needed, you grant a 24-hour access window by verifying your identity with your password. Access is automatically revoked after 24 hours.

8. Data Retention and Deletion

Your data is retained while your account is active. After cancellation, data is retained for 30 days for export, then permanently deleted. You may request immediate deletion by emailing delete_now@develop21.com.

9. Your Rights

Depending on your jurisdiction, you may request access to, correction of, deletion of, or export of your personal data. To exercise these rights, contact data_requests@develop21.com. We respond within 30 days.

10. Cookies

We use essential cookies for authentication and session management only. We do not use advertising cookies or trackers, and we do not serve ads.

11. Changes

We will notify you by email at least 14 days before material changes take effect.
