DeepSeek grants a revocable, non-transferable, non-exclusive right to lawful use under the Terms. Other rights require its written permission, and not exercising a right does not waive it. The separate permission to use Inputs and Outputs, including for model training, remains subject to law and these Terms; it does not transfer the service itself.

Reverse engineering and service scraping are restricted
Under the network-data-theft restriction, DeepSeek lists reverse engineering, disassembly, decompilation, translation or attempts to discover source code, models, algorithms or underlying components, and capturing or copying service content through robots, spiders, other automation or mirrors.

You keep Input rights and receive any Output rights DeepSeek has
Subject to law and the Terms, you retain any rights you have in your Inputs, and DeepSeek assigns any rights it has in your Outputs. “If any” means the clause does not promise that such rights exist. Outputs may be similar to other users’ Outputs, and the assignment does not cover their Outputs.

DeepSeek may use feedback without paying you
By giving feedback, you agree that DeepSeek may use it without restriction or compensation. This concerns feedback, distinct from Section 4.3’s permission to use Inputs and Outputs to a minimal extent for service operation or improvement under encryption and irreversible de-identification conditions, with an opt-out through “Improve the model for everyone.” The text does not state how the two permissions interact when the same content is both feedback and an Input or Output.

If you believe that our service infringes on your intellectual property rights or other rights, or if you find any illegal, false information or behaviors that violate these Terms, or if you have any comments and suggestions about our services, you can submit them by going to the product interface, checking the avatar, and clicking the "Contact Us" button, or by providing truthful feedback to us through our publicly listed contact email as provided in Section 11. We take your opinions seriously and will take legal actions accordingly. We appreciate your feedback, and you agree that we may use it without restriction or compensation to you.
4.3 Under the premise of secure encryption technology processing, strict de-identification rendering, and irreversibility to identify specific individuals, we may, to a minimal extent, use Inputs and Outputs to provide, maintain, operate, develop or improve the Services or the underlying technologies supporting the Services. If you refuse to allow us to process the data in the manner described above, you can opt out by turning off "Improve the model for everyone".

contrast (model-proposed): You can opt out of the stated Input and Output reuse — contrast: Feedback can be used without restriction or compensation; the described Input/Output processing has de-identification conditions and an opt-out.
