I truly want to try it, but these lines give me the heeby jeebies:

  You hereby grant to us, our affiliates and our third party partners (“SPRING Parties”) an unconditional, irrevocable, non-exclusive, royalty-free, sublicensable, transferable, perpetual and worldwide license, to reproduce, use, and modify Your Content in connection with the provision and improvement of the Services and its underlying technologies, as well as for the SPRING Parties' respective business operations, in each case, to the extent permitted by applicable laws.

Which means they own everything that happens on trae and will use it for training, and then:

  You represent and warrant that any names, slogans, trademarks, logos and other designations you use in association with Your Content are owned by or duly licensed to you. You hereby grant SPRING Parties a non-exclusive, royalty-free, perpetual, transferable, sub-licensable, worldwide license to use, modify, reproduce, display, and distribute your relevant names, slogans, trademarks, logos and other designations on the Services for the purposes of operating and providing the Services to you.

Which means that anything you don't own and put on trae will automagically grant them a licence to use it.
