Monte Carlo publishes a conventional enterprise privacy policy with strong customer data ownership terms and a full set of data rights, but it says nothing about AI model training, names no retention period, and does not commit to a breach notification timeframe.

What Monte Carlo's privacy policy and terms of service say about your data

Customer owns its data

The terms state that the customer retains all right, title and interest in the data it makes available, and that Monte Carlo's licence to that data extends only as far as necessary to provide the service.

No AI training disclosure

The privacy policy and terms contain no statement about whether customer data or inputs are used to train models, and no opt-out mechanism is described.

Retention left open-ended

Data is kept "as long as it is necessary or relevant" for the purposes it was collected for, with no number of days, months or years given anywhere in the policy.

Security described only in generalities

Protection is characterised as "industry-standard security measures" without naming encryption, access controls or a security certification, and no breach notification timeframe is promised.

What the policy is silent or vague on

Not stated: keeping user inputs out of model training
Not stated: a way to opt out of training
Not stated: whether training use differs by plan
Not stated: shorter retention for AI conversation logs
