Cartesia's privacy policy, revised June 14, 2024, says content such as text prompts and voice or audio recordings is used to train and enhance the models, unless you submit an opt-out form. Processing that request stops future training use. It does not undo earlier use. The policy does not state how long audio is kept, whether a speaker must consent before a clone is made, or whether a business associate agreement is offered.
