This Privacy Policy explains how Corsac Vantage LLC (“Corsac Vantage,” “we,” “us,” or “our”) collects, uses, and protects information when you use The Prompt Den (the “Service”), a product offered under The Foxhall Factor brand. We respect your privacy and aim to be plain about what happens with your data.

1. Information we collect

a. Information you give us

  • Account info: email address, name (if provided), and authentication tokens from Google when you sign in with Google.
  • Prompts and inputs: the prompts you create, edit, or run; the variables you fill in; the voice samples and custom instructions you provide to train your voice profile.
  • Feedback: messages, bug reports, and prompt requests you submit through the feedback widget.
  • Billing info: if you subscribe to a paid plan, our payment processor (e.g., Stripe) collects payment details. We do not store full card numbers ourselves.

b. Information collected automatically

  • Usage data: the prompts you view, run, or save; AI model calls and token counts (for billing and cost tracking); approximate timestamps.
  • Device and connection data: browser type, operating system, IP address, referring page, and page URL at the time of feedback submission.
  • Cookies and similar technologies: see our Cookie Policy.

c. Information from third parties

When you sign in with Google, we receive basic profile info (email, name, profile picture) from Google in accordance with your Google account settings.

2. How we use your information

  • To create and maintain your account;
  • To deliver the Service — including sending your prompts to AI providers to generate output you request;
  • To personalize your voice profile and tailor AI outputs to your writing style;
  • To process payments and manage subscriptions;
  • To respond to your feedback, bug reports, and prompt requests;
  • To send transactional emails (account, billing, security) and, if you opt in, marketing emails;
  • To monitor usage, prevent fraud, and enforce our Terms of Service;
  • To improve the Service and develop new features;
  • To comply with legal obligations.

3. AI providers and your prompts

When you use AI-powered features (generate, enhance, run with AI), the contents of your prompt — including your voice profile and any input you provide — are transmitted to a third-party large language model provider, currently Anthropic (Claude) or Google (Gemini), depending on your tier and the feature. These providers process your prompt to generate output and operate under their own privacy and data-handling commitments:

As of our last update, Anthropic and Google state that API inputs and outputs are not used to train their public models. We don't use your prompts or outputs to train our own models. Do not submit information you would not be comfortable sharing with these providers.

4. Who else sees your data

We share information only with:

  • Service providers who help us operate the Service:
    • Supabase — database, authentication, file storage;
    • Anthropic and Google — AI model APIs (see Section 3);
    • Stripe — payment processing (if you subscribe to a paid plan);
    • Resend — transactional email (account, feedback digest);
    • Vercel — hosting and content delivery.
  • Authorities when required by valid legal process (subpoena, court order) or to protect our rights, your safety, or the safety of others.
  • Successors if we sell, merge, or transfer the Service or its assets to another business; we will notify you of any material change in how your data is handled.

We do not sell your personal information.

5. Data retention

  • Account data is retained while your account is active and for a reasonable period after deletion for backup and legal purposes.
  • Prompts, voice profiles, and saved content are retained until you delete them or close your account.
  • Feedback submissions are retained indefinitely to track product history, unless you ask us to delete them.
  • Billing records are retained as required by tax and financial laws (typically 7 years).

6. Your rights and choices

Depending on where you live, you may have rights to:

  • Access the personal data we hold about you;
  • Correct inaccurate data;
  • Delete your data (subject to legal retention requirements);
  • Export your data in a portable format;
  • Object to or restrict certain uses;
  • Withdraw consent for marketing emails (unsubscribe link in every email).

To exercise any of these rights, email info@corsacvantage.com. We respond to verified requests within 30 days.

7. Texas, California, and other state residents

We operate from Texas, where the Texas Data Privacy and Security Act gives Texas residents the rights summarized in Section 6. If you are a California resident, the California Consumer Privacy Act (CCPA/CPRA) gives you similar rights, including the right to know what categories of personal information we collect and the right to non-discrimination for exercising those rights. We do not sell or share personal information for cross-context behavioral advertising. To exercise CCPA rights, email info@corsacvantage.com with “CCPA Request” in the subject line.

8. International users

The Service is operated from the United States. If you use the Service from outside the U.S., your information will be transferred to and processed in the U.S. and other countries where our service providers operate. By using the Service, you consent to that transfer.

9. Security

We use industry-standard safeguards (encrypted connections, row-level access control, principle of least privilege) to protect your data. No system is perfectly secure. If we learn of a security incident that affects your data, we will notify you as required by applicable law.

10. Children

The Service is not directed to children under 18. We do not knowingly collect personal information from anyone under 18. If you believe a minor has provided us with personal information, contact us and we will delete it.

11. Changes to this Policy

We may update this Privacy Policy from time to time. The “Last updated” date at the top reflects the most recent change. Material changes will be notified by email or in-product notice.
