Manage Private Compute Core on Android

Private Compute Core (PCC) is a safe, isolated space on your Android phone. It enables smart features like Proactive Assistance, which suggests helpful information and actions across your apps.

By default, PCC keeps your info on your phone. Sometimes, features like Proactive Assistance need help from your assistant app or server to complete a request. For example, it can find a flight time from an email while you text a friend. When that happens, your phone sends only what is needed. It saves a temporary activity log on your device so you can review what was sent.

Important: Data inside PCC is private to you. To make sure only you can see your personal info, your phone locks these logs with your screen lock.

Check your Private Compute Core activity logs

To check your activity logs on your Android device:

1. Open your phone’s Settings app.
2. Tap Security & privacy Privacy dashboard Private Compute Core.
   • On some devices, you can just tap Privacy Private Compute Core.
3. Enter your PIN, password, or biometric.
4. Check or download your logs:
   • View on screen: Tap Proactive Assistance logs to check recent activity by date.
   • Download a copy: Under “Download logs,” tap Download to save an audit .json file to your device.

Important:

• Under “Download logs,” you may find “No logs available.” This happens when no requests have been sent out of PCC during the logging window, or if you cleared them.
• Only requests sent from PCC by Proactive Assistance are currently available in the log.
• PCC does not log general internet activity from other apps or websites on your device.

Manage or delete your saved logs

On the Private Compute Core screen, you can:

• Turn off and delete logs: Turn off Use data logging, then tap Turn off.
  • This immediately erases all saved PCC history on your phone.
• Delete current logs: Tap Delete Delete.
• Turn off Proactive Assistance: Tap Proactive Assistance logs > Proactive Assistance settings.

Choose your logging mode

When Use data logging is on, you are in control of how much detail your device logs:

• Limited: The default logging mode. Keeps an easy-to-read summary. To protect your privacy and storage, these logs are automatically deleted after 72 hours or when log storage is full.
• Detailed: Keeps complete technical logs. These logs are automatically deleted after 12 hours or when log storage is full.

Learn what’s included in your logs

When you check your Proactive Assistance logs or your downloaded .json files, you’ll find:

• Request sent: The question or request sent out of PCC.
• Response (Answer received): The reply sent back for your task.
• Foreground App: The app you used when help started.
• Default digital assistant: The assistant that handled the request.

Can’t find Private Compute Core on your device
