Privacy Policy

1. Overview

This Privacy Policy explains how Knowzeno collects, uses, discloses, stores, and protects information when you use our website, web application, related APIs, emails, and any connected desktop or mobile tools. By using Knowzeno, you acknowledge this Privacy Policy and our Terms of Service.

Knowzeno is a learning and spaced-review service. It may process source notes, audio, learning items, review answers, account information, usage records, and communications you choose to send.

2. Information We Collect

We collect information you provide directly, including account details, profile details, source notes, learning items, review prompts, review answers, audio submitted for transcription, notification preferences, feedback, support messages, and any other content you submit.

We collect information automatically, including device and browser data, IP address, log data, pages viewed, request metadata, referrers, user agent, cookie data, session data, review progress, error data, security events, and service usage data.

We may receive information from service providers and identity providers, including Clerk and any OAuth provider you choose to use. This may include your name, email address, profile image, user identifier, authentication status, and related account metadata.

3. Google OAuth and Google API Data

If you sign in with Google or connect a Google account, we use the Google information authorized by you only to authenticate you, create or maintain your account, secure the service, provide the requested functionality, and communicate with you about the service.

Knowzeno's use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. We do not sell Google user data, use it for advertising, or transfer it except as needed to provide or improve user-facing features, comply with law, protect against security threats, or as otherwise permitted by Google's policies and your consent.

4. How We Use Information

We use information to operate, maintain, secure, personalize, and improve Knowzeno; authenticate users; create and schedule learning items; evaluate review answers; transcribe audio; send service, security, and notification emails; troubleshoot; prevent fraud and abuse; enforce our terms; comply with law; and protect our rights, users, business, and services.

5. Artificial Intelligence Processing

Knowzeno uses AI service providers, including OpenAI, to generate learning items, review prompts, answer evaluations, and transcriptions. Content you submit may be sent to those providers to perform the requested service. AI outputs can be inaccurate or incomplete, and you are responsible for reviewing them before relying on them.

6. Cookies and Similar Technologies

We use cookies, local storage, and similar technologies for authentication, session management, security, review progress, preferences, performance, and basic service operation. Clerk and other service providers may set cookies or similar technologies to provide authentication and security.

7. How We Disclose Information

We may disclose information to service providers and subprocessors that help provide Knowzeno, including hosting, database, authentication, email, infrastructure, AI processing, transcription, security, monitoring, and support providers. We may also disclose information to comply with law, legal process, or government requests; enforce agreements; protect rights, safety, and security; investigate abuse; collect amounts owed; or in connection with a merger, acquisition, financing, restructuring, bankruptcy, or sale of assets.

We do not sell personal information for money. We do not knowingly share personal information for cross-context behavioral advertising.

8. Data Retention

We retain information for as long as reasonably necessary to provide the service, maintain your account, comply with legal obligations, resolve disputes, enforce agreements, prevent abuse, and protect our legitimate business interests. We may retain backups, logs, security records, and legal records after account or content deletion when lawful and reasonably necessary.

9. Security

We use reasonable administrative, technical, and organizational safeguards designed to protect information. No system is perfectly secure, and we cannot guarantee absolute security. You are responsible for protecting your account credentials, devices, and access tokens.

10. Your Choices and Rights

Depending on where you live, you may have rights to access, correct, delete, restrict, object to, or receive a copy of certain personal information. You may also have rights to withdraw consent or appeal a privacy decision. We will honor legally required requests, subject to identity verification and lawful exceptions.

You can contact us at privacy@knowzeno.com. If that address is unavailable, use the support or feedback channel shown in the service.

11. Children

Knowzeno is not intended for children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us personal information, contact us so we can take appropriate action.

12. International Use

We and our service providers may process and store information in the United States and other countries. Those countries may have different privacy laws than your location. By using Knowzeno, you understand that information may be transferred to and processed in those locations.

13. Changes to This Policy

We may update this Privacy Policy from time to time. The updated version will be posted on this page with a new effective date. Your continued use of Knowzeno after an update means you acknowledge the updated policy to the extent permitted by law.
