Careful

Last checked 10 Nov 2026 · Reviewed by Aaron Simmons, security practitioner · How we decide

AssemblyAI's terms say customer data, including audio inputs, may be used to train its models, and that the opt-out applies only to the extent the customer's pricing plan allows it. Paid customers can sign a business associate agreement from the Data Controls page. It is not on until they do. A day count for audio, and a rule for consent before cloning a voice, were not in the terms, privacy policy, or the agreement we read.

Data-safety checklist

Trains on your data by default

Yes

The terms say AssemblyAI may use customer data to develop its products and to train its artificial intelligence and machine learning models. The opt-out is described as applying to the extent of the customer's pricing plan. Customers are also forbidden from using AssemblyAI output to train their own speech models.

How to opt out

Steps

AssemblyAI points customers to its documentation on opting out of the model improvement program, and says availability depends on the pricing plan. We did not treat that help page as a fact about which plans are included, because this review used the terms for the rule itself.

Data retention

What they keep

Unknown for audio. The privacy policy says personal data is kept as long as needed to provide the services or for the purposes it was collected. It does not state a number of days for recordings.

BAA / HIPAA

Yes

AssemblyAI publishes a business associate agreement and says paid customers can sign it from the Data Controls page in the dashboard. Signing is not automatic.

Controls

The customer is responsible for the legality of uploaded audio. A data processing addendum is incorporated into the terms. The training opt-out is plan-dependent rather than described as off for every organization.
