3a. Zero PII Architecture

KKATC does not accept, process, or store personally identifiable information. Questions containing Social Security numbers, EINs, account numbers, routing numbers, credit card numbers, dates of birth, passport numbers, or driver's license numbers are rejected before reaching our AI systems. Any flagged content metadata is auto-deleted within 24 hours via Redis TTL. Raw question content is never stored under any circumstance.

This policy is absolute and non-negotiable. It applies to all KKATC tools including KKATC Tax, KKATC Tax Foundation, KKATC Audit, KKATC Copy, and KKATC Content. Do not submit personal financial data in any prompt. If a question is flagged, the user receives an immediate rejection with instructions to rephrase without personal details.

4. AI Tool Inputs

Questions and prompts you submit to our AI tools (KKATC Tax, KKATC Tax Foundation, KKATC Copy, KKATC Content, and others) are processed by Anthropic's Claude API. By using our AI tools, you acknowledge that your inputs are transmitted to Anthropic for processing in accordance with Anthropic's privacy policy (anthropic.com/privacy).

Do not submit personally identifiable information, Social Security numbers, employer identification numbers, financial account numbers, tax identification numbers, organization names or EINs, donor information, beneficiary information, or other sensitive personal, organizational, or financial data in your prompts. Our tools are designed for general educational use and do not require sensitive personal or organizational data to function. KKATC is not responsible for any sensitive information you voluntarily include in a prompt.
