Brave Leo — privacy & data policy

Provider: Brave. PromptPrivacy score: 86/100. Last verified July 26, 2026.

What happens to your data?

When you use Brave Leo, your prompts and context are sent to a server to generate a response but are not stored or used for training. Conversation history is stored locally on your device only if you choose to enable it, and you can clear this data at any time.

Does it train on your data?

Brave explicitly states they do not use conversations for model training.

Can you opt out?

Yes. You can disable conversation storage in settings, clear history, or stop using the service.

Data retention

Ephemeral; discarded soon after chat is completed. Feedback is retained for 1 year.

Encryption & security

Transport layer encryption is used; large prompts may be cached temporarily. Specific industry certifications like SOC 2 or ISO are not mentioned.

Is it safe for work?

Yes, the privacy-first design, lack of model training, and local storage of history make it suitable for most business use cases, though enterprise-specific compliance certifications are not explicitly listed.
