Is any data used to train LLMs collected in IntelliJ prior to v2025.3.1?

Situation

Some users are concerned that if the 'Data Sharing' option (or another) was briefly enabled e.g. via a trial or exploring other features and products in versions prior to 2025.3.1, there will be data stored from them that can be used to train JetBrains models in the future.

Question

Is any data used to train LLMs collected in versions of IntelliJ prior to 2025.3.1 with the data sharing option enabled?

Answer

No. Until the upcoming release 2025.3.1, the Data Sharing option does not send any detailed code-related data, even if it was manually enabled in the settings. The new data collection model will only apply starting with 2025.3.1.
