2. What Data We Collect

We collect no data. Nexus AI is a fully local application. All user data — conversations, memories, contacts, files, API keys, email credentials — is stored exclusively on your personal computer. No data is transmitted to our servers because we do not operate any servers.

3. What Data Third Parties Receive

When you use Nexus AI, the following third-party services receive data directly from your computer as part of their normal operation:

  • Google Gemini API — your voice and text inputs are sent to Google for AI processing. Governed by Google’s AI Terms of Service.
  • Google Calendar, Drive, Tasks, Gmail API — if you connect your Google account, data flows between your computer and Google’s servers. Governed by Google’s Terms of Service.
  • Telegram API — if you set up Telegram remote control, messages are routed through Telegram’s servers.
  • Email providers — Gmail, Yahoo, or Outlook servers process your emails as part of standard email functionality.

Nexus AI does not add, modify, or intercept data sent to these services beyond what is necessary for the requested functionality.

4. Data Storage

All data is stored at %LOCALAPPDATA%\NexusAI\ on your Windows computer. This includes:

  • Configuration files (API keys, email credentials, preferences)
  • Conversation history (SQLite database)
  • Long-term memory (JSON file)
  • Knowledge base (Markdown files + vector database)
  • Reminders and tasks cache

No data is stored on any remote server owned or operated by Nexus AI.

5. Your Rights Under GDPR

Because all data is stored locally on your computer, you have full control at all times. You can:

  • Access your data by opening the files in %LOCALAPPDATA%\NexusAI\
  • Delete your data by uninstalling the application and selecting “Remove all data”
  • Export your data by copying the NexusAI folder

No request to us is necessary because we never possess your data.

6. Children’s Privacy

Nexus AI is not intended for use by children under the age of 16. We do not knowingly collect data from minors.

7. Changes to This Policy

Any changes to this privacy policy will be posted on this page. Since we collect no data, changes are unlikely.
