Last Updated: March 25, 2026 · Effective Date: March 25, 2026
Naosuu, LLC. ("Company," "we," "our," or "us") respects your privacy and is committed to protecting it through our compliance with this Privacy Policy. This Policy describes how we collect, process, retain, and disclose personal data about you when you download, install, or use the Naosuu Chrome extension and any associated websites or services that link to this Policy (collectively, our "Services").
Naosuu is a privacy-preserving AI prompt-redaction tool designed specifically for legal professionals. The extension intercepts text you enter into AI platforms (such as Claude.ai, ChatGPT, and Google Gemini), detects personally identifiable information ("PII") and legally sensitive data using an on-device detection pipeline, presents a preflight review panel for your confirmation, redacts identified entities with structured placeholders before the text is transmitted, and then rehydrates the AI's response locally in your browser. Your original sensitive data never leaves your device in unredacted form.
This Policy applies only to information we collect through the Services (the Naosuu Chrome extension and any linked website or web portal operated by us), in communications between you and us, and when you interact with our website or extension landing pages that link to this Policy.
This Policy does not apply to information collected by third-party AI platforms (e.g., Anthropic, OpenAI, Google), the Chrome Web Store, or any third-party website that does not link to this Policy.
Our Services are directed exclusively to legal professionals and are not intended for children under the age of 18. We do not knowingly collect personal data from anyone under 18. If we learn that we have collected personal data from a child under 18 without verification of parental consent, we will promptly delete that information.
A. Information You Provide Directly
Contact Information. If you purchase a subscription or contact us for support, we collect your name, email address, and any other information you voluntarily provide.
Payment Information. Payment processing is handled by our third-party payment processor. We do not store full credit card numbers. We may receive tokenized payment identifiers, billing name, and billing address.
B. Information We Do NOT Collect — Core Privacy Architecture
Prompt Content and Legal Texts. The text you type into AI platforms — including any legal memoranda, client communications, case information, or other documents you process through Naosuu — is never transmitted to our servers. All PII detection and redaction occurs entirely on your device.
Redacted Entities and Placeholder Maps. Session maps are stored in chrome.storage.session, automatically cleared when you close the tab or restart your browser, and never transmitted to our servers.
AI Platform Responses. The responses generated by third-party AI platforms are rehydrated locally in your browser. We do not intercept or store AI-generated content.
We collect information when you purchase or activate a subscription, contact us for support, participate in surveys or promotional activities, or otherwise voluntarily provide us with information.
We do not use any automatic data collection technologies, cookies, nor analytics tools. We do not use behavioral tracking or cross-site advertising tracking technologies. We do not serve targeted advertisements.
We use the information we collect to: process and fulfill subscription purchases and send transactional communications; respond to inquiries and provide customer support; maintain the security and integrity of the Services; comply with applicable legal obligations; and notify you of updates and material changes to the Services.
We do NOT use your information to train machine learning models, sell data to third parties, or engage in targeted behavioral advertising.
chrome.storage.local: Used to store your extension settings (Protection On/Off toggle, Sensitive Session Mode toggle). This data persists on your device and is not transmitted to our servers.
chrome.storage.session: Used to store session-scoped placeholder maps. This data is automatically cleared when you close the tab or restart your browser and is never transmitted externally.
We may disclose personal data to: service providers and contractors (payment processors, cloud hosting, authentication services, customer support platforms); successors in interest in connection with a merger, acquisition, or asset sale; and as required by law, court order, subpoena, or regulatory request.
We do not sell your personal data to third parties. We do not disclose your personal data to advertisers or data brokers.
Naosuu is designed to work in conjunction with Claude.ai (Anthropic), ChatGPT (OpenAI), and Gemini (Google). These platforms are not our service providers. When you use Naosuu, only your redacted prompt text is transmitted to those platforms. Their own privacy policies govern how they handle the redacted text they receive. We encourage you to review the privacy policies of any AI platform you use in conjunction with our Services.
Depending on your state of residency, you may have rights to: access and data portability; correction of inaccuracies; deletion of personal data; opt out of sale or sharing (we do not sell personal data); and opt out of targeted advertising and profiling (we do not engage in these activities).
California Residents: You have additional rights under the CCPA/CPRA. We do not sell or share your personal data as defined under California law.
Nevada Residents: We do not currently sell personal data triggering Nevada's opt-out requirements.
We use commercially reasonable administrative, physical, and technical safeguards. Our core privacy protection is architectural: because prompt content, vault entries, and session maps are processed entirely on your device and never transmitted to our servers, those categories of data are not exposed to server-side security risks. No electronic transmission over the Internet is completely secure; any such transmission is at your own risk.
We retain personal data for as long as reasonably necessary to fulfill the purposes for which it was collected and to comply with applicable legal obligations. Session map data is automatically cleared when you close the relevant browser tab or restart your browser. Account information is retained for the duration of your account relationship and a reasonable period thereafter.
We may update this Policy from time to time. We will notify you of material changes by updating the "Last Updated" date. Your continued use of the Services after the effective date of any update constitutes your acceptance of the revised Policy.
