This is what AI said when I asked if the free version was time-limited:
Yes, the free version of Flightradar24 is time-limited. Specifically, the website times out after 30 minutes of continuous use. Additionally, free users are limited to 7 days of historical flight data and only 3 sessions in the 3D view, along with having advertisements displayed throughout the app and website.
