It’s a bit of a hassle, but after closing the Windows command, you can restart the program and use it indefinitely. The results you worked on will still remain in the workspace folder.

Yeah, felt like it positions itself as open source project here and on GitHub, but buries the cost in other pages... Doesn't even say the subscription cost anywhere I could find (in English). Not a huge fan of this advertising model.

I haven’t looked at the code, but can you just patch out the 30 minute limit?

Looks to me like the app code is compiled into pyd files. One could try and decompile. Interestingly, it's licensed as MIT.
