Does JetBrains AI Assistant / Junie (Individual non-commercial license) train on your code?

Trains on code

Yes, unless you opt out

Default

How to opt out

IDE Settings > data-sharing preferences (JetBrains: 'You may opt out in the product settings'). Preferences apply across all installed JetBrains IDEs.

Retention

Detailed code-related data: 1 year. Other AI inputs/outputs 'may be stored and used for a limited period' for abuse monitoring.

Notes

The JetBrains AI Terms say inputs won't train code-generating models 'unless You expressly agree'; the Product Data notice treats non-commercial licenses as default-on under 'legitimate interest'. We score the stricter, default-on reading.
