Cursor vs JetBrains

On what the policies say, JetBrains is the better choice for your data: graded C against Cursor's D.

Grades read the plan most people are on. Each company's full entry has every plan, every clause and the archived copy it was read from.

Cursor

With Privacy Mode off, Cursor trains on your codebase, prompts and editor actions. The switch is free on every plan — but you have to find it.

Verdict

By default: Trains on you by default
The way out: A self-serve opt-out exists
What D means: On by default. An opt-out exists, but you have to go looking for it.
Last checked: 5 Oct 2026

JetBrains

JetBrains' AI terms undertake not to train on your code unless you expressly agree. The data sharing that feeds training is off by default on paid licences and on by default on free ones.

Verdict

By default: Trains on you by default
The way out: A self-serve opt-out exists
What C means: On by default, and the product tells you so. One switch, in settings, on every plan.
