Do Cursor’s privacy rules apply to extensions? For example, we’re interested in trying the Mermaid extension with Cursor but want to make sure our data is still secure.

Thank you!

Thats a good question as there is currrently no mention of marketplace @deanrie . However note that most extensions are made by 3rd parties who usually have to comply with VSCode marketplace requirements. Some may have telemetry which you can turn off.
