Suno — privacy & data policy

Provider: Suno. PromptPrivacy score: 32/100. Last verified November 01, 2026.

What happens to your data?

Suno processes your text prompts, audio uploads, and voice samples to generate musical tracks and personalize your experience. It also uses this information to train its underlying AI models and shares it with third-party service providers for hosting, processing, and analytics. Data is primarily stored in the United States and retained as long as deemed necessary for business and legal purposes.

Does it train on your data?

Trains on your content by default. Suno uses your prompts, uploaded media, chat inputs, and voice recordings to train and improve its AI models under legitimate interests.

Can you opt out?

Not specified. The policy indicates that user content is used to train AI models, but it does not describe an opt-out toggle or setting to exclude user content from model training.

Data retention

Suno retains your personal information for as long as reasonably necessary to fulfill service delivery, account administration, legal compliance, and dispute resolution. Biometric information extracted from voice recordings is retained for a maximum of three years following your last interaction, unless otherwise required by law.

Encryption & security

Suno notes that it applies commercially reasonable security measures and safeguards, but it does not specify standard encryption protocols (such as TLS or AES) or third-party audits (like SOC 2 or ISO 27001). The policy explicitly notes that electronic data may not be secure while in transit.

Is it safe for work?

Caution is advised for business environments. Suno trains its models on user inputs by default without an explicit opt-out mechanism, does not detail robust encryption standards, and explicitly notes data may not be secure in transit. Businesses should use custom enterprise agreements where Suno acts strictly as a data processor.
