Final Cut Pro is Apple's professional video editing application for Mac and iPad. It offers a magnetic timeline, isolation of people and objects without a green screen, transcript and visual search, automatic captions, colour grading, audio tools and export to Apple ProRes. On the Mac it can be bought once from the App Store, and it is also included in the Apple Creator Studio subscription. The pages consulted list no one-time purchase for the iPad.
Apple Inc. is a US company. Its privacy policy states that personal data is generally stored by Apple Inc. in the United States and may be transferred to or accessed by entities around the world. For users in the EEA, the UK and Switzerland, Apple Distribution International Limited in Ireland is the controller, and transfers are governed by standard contractual clauses. The product page does not present Final Cut Pro as open-source software and does not describe a vendor-hosted editing service. For a European organisation the relevant point is therefore a US group under US jurisdiction, with commercial software and no open-source option.
