Cortex Privacy Policy

Last Updated: July 26, 2025

Welcome to Cortex. The Cortex application and related services ("Service") are provided by the individual developers known as Vertex ("we," "us," or "our"). This Privacy Policy explains the specific data practices for the Cortex Service and supplements the general Vertex Privacy Policy, which applies to the entire Vertex ecosystem.

This document should be read in conjunction with the general Vertex policy and our Cortex Terms of Service. By using the Service, you acknowledge and agree to the data practices described in these documents. An account created for Cortex is a unified Vertex Account, usable across our ecosystem of apps and games.

A) Information We Collect

We collect information in a few different ways to provide and improve our services:

B) How We Use and Share Information

We use the information we collect primarily to provide, maintain, and secure our services. This includes authentication, enabling features, and communicating with you. More specifically:

1. Offline Models: Privacy and Safety

When you use an offline model, we are committed to providing the highest level of privacy. However, to ensure a safe user experience, we have implemented a hybrid approach:

This approach allows us to ensure a secure and responsible environment while keeping the content of your personal conversations private and on your device.

2. Online Model Data Flow and Moderation

When you use an online model, your data (prompts and images) undergoes a multi-step process designed for safety and functionality. This same safety-first approach also applies when you create a new custom AI model.

3. The Vertex Ecosystem and Data Separation

Your Vertex Account allows for a seamless experience across our products. However, we maintain strict data separation. Your activity, conversations, and technical data from Cortex are never used to track you or personalize your experience (e.g., show ads) in other Vertex apps or games.

4. Handling of User Reports and Content Moderation

To ensure the safety and integrity of our Service, we provide an in-app tool for you to report content you believe violates our policies. When you submit a report, we collect specific data for the sole purpose of investigating the issue, enforcing our Terms of Service, and improving our AI safety mechanisms. The information we collect includes:

This data is handled with strict confidentiality and is used exclusively for content moderation and service improvement. It is never used for advertising, user profiling, or any other purpose unrelated to maintaining a safe and functional environment.

C) Your Rights and Data Control

You are in full control of your data.

D) Transparency and Open Source

We are committed to full transparency. The Cortex application is open source. We encourage you to review our code on GitHub to see exactly how your data is handled.

E) Children's Privacy

Our services are not directed to or intended for use by individuals under the age of 13. In alignment with our Google Play Store target audience declaration, we do not knowingly collect personal information from children under 13.

If we become aware that we have inadvertently collected personal information from a child under 13, we will take immediate steps to delete that information from our systems. If you are a parent or guardian and believe your child has provided us with personal information, please contact us so we can take action.

F) Security

We and our partners use industry-standard security measures. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

G) Limitation of Liability

Cortex integrates with essential third-party services to function, including but not limited to, Cloudflare, Google Firebase, OpenAI, and OpenRouter. We select our partners carefully and implement industry-standard security measures to protect the data we handle. However, we do not control the internal data practices or security of these third parties. Their handling of your data is governed by their own respective privacy policies.

While we strive to work with reputable partners, you acknowledge that using services that rely on a chain of providers carries inherent risks. We encourage you to review the privacy policies of our key partners to make an informed decision. By using our service, you understand and accept that the ultimate responsibility for data security within a third-party's platform lies with that provider.

H) Changes to This Privacy Policy

We reserve the right, at our sole discretion, to modify or replace this Privacy Policy at any time. We will indicate any changes by updating the "Last Updated" date at the top of this Policy. For any significant changes, we will provide a more prominent notice, such as through an in-app notification or by sending an email to the address associated with your account. Your continued use of our Service following the posting of any changes constitutes acceptance of those changes.
