Cortex AI - Your Private Offline AI Assistant

Last Updated: January 9, 2026

TL;DR: Cortex AI is a completely offline AI assistant. We don't collect, store, transmit, or process any of your data. Everything stays on your device. Period. 100% PRIVATE

1. Information We Collect

None.

Cortex AI does not collect any personal information, usage data, analytics, telemetry, or any other information from you or your device.

2. How We Use Information

Since we don't collect any information, we don't use, process, analyze, or share any data.

3. Data Storage

All conversations, settings, and preferences are stored locally on your device only using iOS's secure document storage. This data never leaves your device under any circumstances.

What's Stored on Your Device:

  • Conversations: All your chat history, stored in your device's local file system
  • Language Preferences: Your selected language, stored in local storage
  • App Settings: Pinned conversations and other preferences, stored locally
  • AI Model: Downloaded once on first launch, stored on your device for offline use

Important: No cloud storage, no server synchronization, no remote backups.

4. Data Sharing

We don't share any data because we don't collect any data. There is absolutely no transmission of your conversations, queries, or any other information to external servers or third parties.

5. Third-Party Services

Cortex AI does not integrate with, use, or connect to:

  • Analytics platforms (no Google Analytics, Firebase, etc.)
  • Advertising networks
  • Social media services
  • Cloud storage providers
  • Any third-party APIs or services

One-Time Model Download

On first launch, the app downloads an AI model from a content delivery network (CDN). This is a one-time download only. The model file is approximately 500MB-1GB. After this initial download, the app operates completely offline with no internet connection required.

6. Internet Connectivity

Internet connection is required only for:

  • Initial app download from the App Store
  • One-time AI model download on first launch
  • App updates (optional)

After the model download is complete, you can use Cortex AI entirely offline, including in airplane mode. The app will never attempt to connect to the internet again unless you manually update it.

7. Children's Privacy

Cortex AI does not knowingly collect any information from anyone, including children under the age of 13. Since we don't collect any data at all, the app is safe for users of all ages.

8. Data Security

Your data is secured by iOS's built-in security features:

  • Device Encryption: All data is encrypted when your device is locked
  • App Sandboxing: App data is isolated from other apps
  • No Transmission: Data never leaves your device
  • Local-Only Processing: All AI processing happens on your device

9. Your Rights and Control

Since all data is stored locally on your device, you have complete control:

  • Access: All your data is accessible within the app at all times
  • Modify: Edit or rename any conversation
  • Delete: Delete individual conversations or uninstall the app to remove all data
  • Export: Your conversations remain on your device; you control all data
  • Portability: Data stays with you on your device

10. Changes to This Privacy Policy

If we make changes to this privacy policy, we will update this page and the "Last Updated" date at the top. We will also notify users through app updates if significant changes are made.

Continued use of the app after changes indicates acceptance of the updated policy.
