TVP VOD is the streaming platform of Telewizja Polska S.A. (TVP), the Polish public broadcaster. It offers series, programmes, films, TV theatre and premieres of TVP productions, as well as live TV channels. According to Wikipedia, there is a content library alongside paid packages (TVP VOD+, Strefa ABO and Filmy na życzenie) with premium content. You use it at vod.tvp.pl and through apps and devices.
TVP is based in Warsaw and is wholly owned by the Polish State Treasury. There is no foreign parent company, so ownership gives no CLOUD Act signal. Wikipedia reports that the company was placed in liquidation in late 2023 after the president blocked its funding. The service is not open source and is offered by TVP itself as a hosted web service. The pages consulted do not state where the platform hosts data.
