Security Guarantees & Quick FAQs

Everything runs locally in your browser with zero data logging.

Is my text, code, or data sent to any server?

No. NakedPrompt executes 100% locally on your computer inside your web browser. No backend server, cloud database, or AI model ever receives your prompts or text. You can verify this by checking your browser's Network tab or even using the app completely offline.

How does token reduction save costs and context window space?

AI models (OpenAI, Anthropic, Google) charge per token and have finite context windows. Stripping redundant HTML clutter, zero-width characters, and excess whitespace reduces token usage by 15% to 50% without altering the meaning of your text.

What types of sensitive data are automatically masked?

Email addresses, international phone numbers, SSNs, credit card numbers (Luhn checked), IPv4/IPv6 addresses, OpenAI API keys (sk-...), AWS credentials (AKIA...), GitHub tokens (ghp_...), and Bearer auth tokens.

Can I inspect the original values or restore them?

Yes! Click the 'PII Dictionary' button above the output window to see all masked items and their corresponding placeholders during your session.
