Privacy Policy
Effective Date: April 27, 2026
QuillanAI Inc. d/b/a Zuben — A Delaware Corporation
Contents
This Privacy Policy describes how QuillanAI Inc. d/b/a Zuben (“Zuben,” “we,” “our,” or “us”) collects, uses, discloses, retains, and protects personal information when you visit our website, create an account, or use the Platform. It also describes your rights under applicable privacy laws and how to exercise them. This Privacy Policy applies to all individuals who interact with Zuben, including Subscribers, Authorized Users, website visitors, and prospective customers. It does not apply to information processed by Subscribers through the Platform on behalf of their clients — Subscribers are the controllers of that data, and their own privacy policies govern their clients' information.
Article I — Information We Collect
1.1 Account Information
When you create an account or subscribe to the Platform, we collect information necessary to establish and manage your subscription, including your name, email address, business name, job title, billing address, and payment information. If you are an Authorized User added by a Subscriber, we collect the information the Subscriber provides to us about you (typically your name and email address).
1.2 Subscriber Data
When Subscribers and Authorized Users use the Platform, they provide Subscriber Inputs (prompts, queries, documents, and context) and the Platform generates Outputs (work products, analyses, and memoranda). As described in our Terms of Service, Subscriber Data is processed solely to deliver the Platform services and is never used to train our AI models. Subscriber Data may contain personal information about the Subscriber's clients or other third parties — Zuben processes this information at the direction and on behalf of the Subscriber, who is the controller of that data.
1.3 Usage Data
We automatically collect information about how you interact with the Platform, including: feature utilization data, session timestamps and duration, work product types generated, error logs, browser type and version, operating system, IP address, device identifiers, and referring URLs. This data is collected in aggregate, de-identified form that cannot be used to reconstruct Subscriber Data or identify any individual's Subscriber Inputs or Outputs.
1.4 Communications
When you contact us for support, provide feedback, or otherwise communicate with us, we collect the content of those communications along with your name and contact information.
1.5 Cookies and Tracking Technologies
Our website and Platform use cookies and similar technologies to maintain session state, authenticate users, remember preferences, and collect analytics data. We use:
- Strictly Necessary Cookies — required for the Platform to function (authentication, security, session management). These cannot be disabled.
- Analytics Cookies — help us understand how the Platform is used so we can improve it. We use analytics providers with IP anonymization enabled.
- Preference Cookies — remember your settings and preferences across sessions.
We do not use advertising cookies or tracking pixels. We do not sell personal information. We do not engage in cross-context behavioral advertising.
Article II — How We Use Your Information
2.1 Service Delivery
We use your information to provide, maintain, and improve the Platform, including to process Subscriber Inputs and generate Outputs, manage your account, process payments, provide customer support, and communicate with you about your subscription.
2.2 Platform Improvement
We use aggregate, de-identified usage data (not Subscriber Data, Subscriber Inputs, or Outputs) to monitor Platform performance, identify and fix errors, analyze usage patterns, and improve the Platform's features and functionality.
2.3 Security and Fraud Prevention
We use your information to detect, prevent, and respond to security incidents, fraud, abuse, and violations of our Terms of Service and Acceptable Use Policy.
2.4 Legal Compliance
We use your information as necessary to comply with applicable laws, regulations, legal processes, and governmental requests.
2.5 Communications
We use your contact information to send transactional communications (account confirmations, billing notices, security alerts, service updates) and, with your consent where required, promotional communications about new features or services. You may opt out of promotional communications at any time.
2.6 No Training on Subscriber Data
We do not use Subscriber Data, including Subscriber Inputs and Outputs, to train, fine-tune, retrain, improve, or otherwise develop any machine learning model, artificial intelligence system, algorithm, or derivative technology. This prohibition is absolute. It is set forth in our Terms of Service and restated here for clarity.
Article III — How We Share Your Information
3.1 Service Providers (Subprocessors)
We share personal information with third-party service providers who perform services on our behalf, including cloud infrastructure providers, payment processors, analytics providers, and customer support tools. Each service provider is bound by written agreements imposing data protection obligations no less protective than those in this Privacy Policy.
3.2 Legal Requirements
We may disclose personal information if required by law, regulation, legal process, or governmental request, or if we believe in good faith that disclosure is necessary to protect our rights, the safety of any person, or to detect and prevent fraud or security issues. Where legally permitted, we will provide you with advance notice of such disclosure.
3.3 Business Transfers
In connection with a merger, acquisition, reorganization, bankruptcy, or sale of all or a portion of our assets, personal information may be transferred to the acquiring entity. We will provide notice before your personal information becomes subject to a different privacy policy.
3.4 With Your Consent
We may share your information for any purpose disclosed to you at the time of collection with your consent.
3.5 No Sale of Personal Information
We do not sell personal information. We do not share personal information for cross-context behavioral advertising. We have not sold or shared personal information in the preceding twelve (12) months.
Article IV — Data Retention
4.1 Subscriber Data
Subscriber Data (including Subscriber Inputs and Outputs) is retained in encrypted form during the active session and for the Retention Period specified in the applicable Terms of Service or Order Form (default: 30 days) following each session, solely to enable retrieval and download of Outputs. Upon expiration of the Retention Period, Subscriber Data is automatically and irreversibly purged from all active systems. Subscribers may trigger immediate deletion at any time through the Platform's data management interface.
Upon expiration or termination of a subscription, Subscriber Data is available for export for thirty (30) days and thereafter deleted within thirty (30) days, except to the extent retention is required by applicable law.
4.2 Account Information
We retain account information for as long as your account is active and for a reasonable period thereafter to comply with legal obligations, resolve disputes, and enforce our agreements. After account closure, we retain only the minimum information necessary for these purposes and delete the remainder.
4.3 Usage Data
Aggregate, de-identified usage data is retained for up to twenty-four (24) months for analytics and Platform improvement purposes. This data cannot be used to identify any individual or reconstruct any Subscriber Data.

- Right to Data Portability. You have the right to obtain your personal information in a portable, readily usable format.
- Right to Non-Discrimination. We will not discriminate against you for exercising your privacy rights. We will not deny services, charge different prices, or provide a different quality of service because you exercised a privacy right.
- Right to Appeal. If we deny your privacy rights request, you have the right to appeal that decision. See Section 5.4 below.
5.2 How to Exercise Your Rights
You may submit a privacy rights request by:
- Emailing us at privacy@zuben.ai;
- Using the privacy request form on our website; or
- Writing to us at our physical address.
We will verify your identity before processing your request. For access and deletion requests, we will verify your identity using at least two data points matching the information we maintain about you. If we cannot verify your identity, we will notify you and explain what additional information is needed.
5.3 Response Timelines
We will acknowledge your request within ten (10) business days and provide a substantive response within forty-five (45) calendar days of receipt. If we require additional time (up to an additional forty-five (45) days), we will notify you of the extension and the reason.
5.4 Appeal Process
If we deny your privacy rights request in whole or in part, we will provide a written explanation of the basis for the denial and instructions for submitting an appeal. You may appeal by emailing privacy@zuben.ai with the subject line "Privacy Rights Appeal." We will respond to your appeal within sixty (60) days. If we deny your appeal, we will provide you with information on how to contact your state's attorney general or other relevant regulatory authority.
5.5 Authorized Agents
You may designate an authorized agent to submit privacy rights requests on your behalf. Authorized agents must provide written proof of authorization (such as a power of attorney or a signed authorization form) and we may verify your identity directly before processing the request.
5.6 Universal Opt-Out Mechanisms
We honor Global Privacy Control (GPC) signals and other universal opt-out mechanisms recognized under applicable law. When we detect a GPC signal, we treat it as a valid opt-out request for the sale and sharing of personal information associated with that browser or device.
Article VI — Sensitive Data
6.1 Sensitive Personal Information
We do not intentionally collect sensitive personal information (as defined by applicable state privacy laws) directly from users as part of the account creation or subscription process. However, Subscriber Data uploaded to the Platform may contain sensitive personal information about the Subscriber's clients or other third parties. Zuben processes this information at the direction and on behalf of the Subscriber, who is responsible for obtaining any required consent for the processing of sensitive data.
6.2 Children's Information
The Platform is designed for use by licensed attorneys, law students, and legal professionals. It is not directed to individuals under the age of sixteen (16), and we do not knowingly collect personal information from children. If we learn that we have collected personal information from a child under 16, we will promptly delete it.
Article VII — Security
7.1 Security Safeguards
We maintain administrative, technical, and physical safeguards designed to protect personal information against unauthorized access, use, alteration, disclosure, and destruction. These safeguards are described in our Terms of Service and include encryption in transit and at rest, access controls, regular security assessments, incident detection and response procedures, and employee security training. Zuben is pursuing SOC 2 Type II certification. While we implement commercially reasonable security measures, no system is completely secure, and we cannot guarantee the absolute security of your information.
Article VIII — Automated Decision-Making Technology
8.1 How the Platform Uses Automated Processing
The Platform uses artificial intelligence and automated processing to generate Outputs (legal research, analysis, and work products) based on Subscriber Inputs. This processing is performed at the direction and under the supervision of the Subscriber and its Authorized Users, who are licensed attorneys responsible for independently reviewing, verifying, and approving all Outputs before use.
8.2 No Automated Decisions with Legal or Similarly Significant Effects
Zuben does not use automated decision-making technology to make decisions that produce legal or similarly significant effects on consumers without human involvement. All Outputs are advisory in nature and require human review and approval before use. The Platform does not make hiring decisions, credit decisions, insurance decisions, or other consequential determinations about individuals.
8.3 California ADMT Disclosure
To the extent the California Privacy Protection Agency's regulations on Automated Decision-Making Technology (ADMT) apply to the Platform, this Section 8 constitutes the required disclosure. Subscribers and Authorized Users have the right to opt out of ADMT and to request information about how the Platform's automated processing functions. Because all Platform Outputs require human review and approval by a licensed attorney before use, the Platform operates as a decision-support tool under attorney supervision, not as an autonomous decision-making system.
Article IX — State-Specific Disclosures
9.1 California Residents (CCPA/CPRA)

10.1 Cross-Border Data Transfers
The Platform is operated from the United States and is designed for use by attorneys licensed in the United States. If you access the Platform from outside the United States, your information may be transferred to, stored in, and processed in the United States, where privacy laws may differ from those in your jurisdiction.
