Privacy Policy

Knowledge Hunter — a product of Luminous Gateway, LLC

Last Updated: May 23, 2026

Summary (Plain-Language Overview)

This summary highlights the key points of our privacy practices. Please read the full Policy below for details. Luminous Gateway, LLC ("we," "us," or "our") provides Knowledge Hunter (the "Service"), a consumer mobile app for working with sources, chats, and AI-generated content.

1. Scope and Roles

This Privacy Policy describes how Luminous Gateway, LLC collects, uses, discloses, retains, and otherwise processes personal information in connection with the Service, including the Knowledge Hunter mobile app, the websites at knowledgehunter.ai and share.knowledgehunter.ai, and related backend services. Luminous Gateway, LLC is the controller (or equivalent) of the personal information we process to provide the Service. Where we process information on behalf of a third party (for example, content you import via Notion), the third party may also have its own role and obligations.

2. Categories of Information We Collect

We collect the following categories of information:

2.1 Account and Authentication Data

2.2 User-Provided Content

2.3 Subscription and Billing Identifiers

2.4 Usage and Device Data

2.5 Integration Data

2.6 Communications

3. Sources of Information

We obtain information from the following sources:

4. How We Use Information

We use information for the following purposes:

Where applicable law (such as the EU/UK GDPR, the laws of California, Brazil, Canada, Australia, Japan, South Korea, India, and similar regimes) requires us to identify a legal basis or justification for processing, we rely on one or more of the following, depending on the activity:

Where local law uses different terms (e.g., “business purposes” under California law), we rely on the closest equivalent justification permitted by that law.

6. AI Processing and Transparency

Knowledge Hunter is built around AI features. This section explains how AI processing works in the Service.

6.1 What goes in (Inputs)

When you ask a question, summarize a source, or otherwise use AI features, we send your inputs — which can include your prompt, the content of selected sources, related conversation history, and metadata — to one or more AI or data providers via our Cloud Functions.

6.2 What comes out (Outputs)

The provider returns AI Output, which we display to you and store with your Account so you can revisit it. AI Output may be inaccurate, incomplete, biased, outdated, or otherwise unsuitable for a particular purpose.

6.3 Providers we currently use

Each provider has its own privacy practices, security posture, and retention policies. We may add, change, or remove providers as the Service evolves and will update this Policy when we do. Each provider may use your inputs and the resulting AI Output to operate, secure, monitor, evaluate, and improve its services and models, including for training and refining AI models, in accordance with its own terms. We do not fully control or audit a provider’s internal handling of data, and by using AI features you consent to this provider-side processing. If you do not want your inputs to be processed in this way, do not use the Service’s AI features.

6.4 Quality and safety limitations

Although we apply reasonable filtering and abuse-prevention measures, AI Output may include errors, fabrications (“hallucinations”), or content that resembles third-party material. Do not rely on AI Output as professional advice or in high-risk contexts. You are responsible for reviewing AI Output before relying on it.

7. How We Share and Disclose Information

We share information with the categories of recipients described below.

7.1 Service Providers and Processors

We use trusted vendors to deliver the Service, including:

These providers process information under written agreements that limit their use of personal information to the purposes for which we engage them, except for de-identified or aggregated data and except as otherwise required by law.

7.2 Public Sharing by You

If you create a Share Link (for example, on share.knowledgehunter.ai), the Content and AI Output behind the link is publicly accessible to anyone who has the URL, with no Account required. Search engines and other third parties may index, copy, or archive the page. Do not share sensitive personal, confidential, or regulated information through Share Links.

We may disclose information when we believe in good faith that disclosure is necessary to: (a) comply with applicable law, regulation, legal process, or governmental request; (b) enforce these Terms, including investigation of potential violations; (c) detect, prevent, or otherwise address fraud, security, or technical issues; or (d) protect against harm to the rights, property, or safety of Luminous Gateway, LLC, our users, or the public.

7.4 Business Transfers

If we are involved in a merger, acquisition, financing, reorganization, bankruptcy, or sale of assets, information may be transferred as part of the transaction, subject to standard confidentiality protections. We will notify you of any change of controller as required by law.

We share information with other parties at your direction (for example, when you authorize an integration) or with your consent.

7.6 No Sale of Personal Information

We do not sell personal information for money. We do not engage in cross-context behavioral advertising. Some jurisdictions define “sale” or “share” broadly; if and to the extent any of our disclosures fall within those broad definitions, we will provide the disclosures and opt-out mechanisms required by applicable law.

8. Public Content and Share Links — Important Warning

Anything you make publicly available through Knowledge Hunter — including any URL on share.knowledgehunter.ai — is accessible to anyone who has the link. We do not authenticate or limit who can view a Share Link. Once a link is public, third parties may save, copy, repost, or index it. We may not be able to remove copies stored elsewhere. Do not include any personal, sensitive, confidential, or regulated information in anything you intend to share.

9. Data Retention

We retain your Account, your Content, AI Output, and associated metadata until you delete them or delete your Account. You can delete your Account at any time using the in-app account deletion feature, which removes your Account and your associated stored Content from our active systems. Some categories of information may be retained for limited additional periods where necessary to:

Third-party providers may retain logs or data they process on our behalf for their own technical, security, or compliance purposes, subject to their own retention policies.

10. Security

We use a combination of administrative, technical, and physical safeguards designed to protect personal information, including encryption in transit (TLS/HTTPS), encryption at rest where supported by Google Cloud / Firebase, identity and access controls, secure authentication, principle-of-least-privilege access for our team, audit logging, and ongoing monitoring. No system is perfectly secure, and we cannot guarantee the absolute security of any data. You are responsible for using a strong, unique password and for keeping your device and credentials safe.

11. Children’s Privacy

Knowledge Hunter is intended only for users 18 years of age and older. We do not knowingly collect personal information from anyone under 18. If we learn that we have collected personal information from a person under 18, we will delete that information and terminate the Account. If you believe a child under 18 has provided us with personal information, please contact support@knowledgehunter.ai.

12. International Data Transfers

We are headquartered in the United States and use cloud infrastructure (including Google Cloud / Firebase) and AI providers with operations in the United States and other countries. When you use the Service, your information may be transferred to, stored in, and processed in the United States and other jurisdictions whose data-protection laws may differ from those in your country.

Where required by applicable law (such as the EU/UK GDPR), we rely on appropriate transfer mechanisms, such as the European Commission’s Standard Contractual Clauses, the UK International Data Transfer Addendum, equivalent mechanisms, your explicit consent, or the contractual necessity of providing the Service. By using the Service, where permitted by law, you acknowledge these transfers.

13. Your Privacy Rights

Depending on where you live, you may have rights with respect to your personal information, including:

Some rights only apply in certain jurisdictions and may be subject to legal exceptions. We will respond to verifiable requests as required by applicable law.

14. How to Exercise Your Rights

To exercise any of the rights described above, email us at support@knowledgehunter.ai from the email address associated with your Account, and tell us which right you would like to exercise. We may need to verify your identity before fulfilling certain requests, for example by asking you to confirm information about your Account. If you would like an authorized agent to act on your behalf, we may ask the agent to provide written authorization and may also contact you to verify the request.

You may also delete your Account and associated Content directly from within the app using the in-app account deletion feature.

15. Account Deletion

You can delete your Account at any time from within the app. Account deletion will: (a) remove your Account credentials from Firebase Authentication; (b) delete your user profile and the chat, source, and message data stored under your Account in Cloud Firestore; and (c) cancel ongoing AI processing for your Account. Some residual data may persist for a limited time in encrypted backups, anti-abuse logs, or where retention is required by law, as described in Section 9. Deleting your Account does not by itself cancel an active Subscription. To stop billing, cancel through Google Play (for Android Subscriptions) or contact us at support@knowledgehunter.ai to cancel a Stripe-billed iOS Subscription before deleting your Account; Subscriptions billed by Apple must be canceled in your Apple ID settings.

16. Cookies, SDKs, and Similar Technologies

The Service uses SDKs and similar technologies to authenticate users, persist sessions, deliver core functionality, and measure performance, including SDKs from Firebase, RevenueCat, and Superwall. The websites at knowledgehunter.ai and share.knowledgehunter.ai may use a small number of strictly necessary cookies and, where applicable, performance cookies. Where required by law, we will request your consent before setting non-essential cookies and provide controls to manage them.

17. Communications and Notifications

We may send you transactional emails (e.g., email verification, security notices, billing notifications) and, where you opt in, push notifications or product updates. You can unsubscribe from non-transactional emails using the link in the email or by contacting support@knowledgehunter.ai. You can manage push notifications in your device settings.

18. Region-Specific Disclosures

18.1 California (CCPA/CPRA)

If you are a California resident, the categories of personal information described in Section 2 correspond to categories under the California Consumer Privacy Act (CCPA), as amended by the CPRA. We collect this information for the business and commercial purposes described in Section 4. We disclose information to the categories of recipients described in Section 7. We do not sell personal information for money and do not knowingly engage in cross-context behavioral advertising.

If you are in another jurisdiction with a comprehensive privacy law (such as Brazil’s LGPD, Canada’s PIPEDA/Quebec Law 25, Australia’s Privacy Act, Japan’s APPI, South Korea’s PIPA, or India’s DPDP Act), the rights and obligations described in this Policy are intended to be implemented in a manner consistent with applicable law.

19. Changes to This Policy

We may update this Privacy Policy from time to time. We will post the updated version in the Service and update the “Last Updated” date at the top.
