Does Perplexity train on your data?

By default it can. On the consumer tier Perplexity uses your inputs to improve models unless you opt out. Its business tier typically does not.

What we checked

This assessment separates the consumer product from any business plan. It uses the vendor documents linked below; an unverified item is not a pass.

Default data training: Opt-out required; On consumer/free/Pro accounts an 'AI data retention' setting is on by default and can be used to improve models; logged-in users can opt out in Settings > Account, but logged-out users cannot.
Business-tier training: No by default; Perplexity Enterprise Pro and the Sonar API operate under Zero Data Retention and state customer/enterprise data is never used to train models.
Training control: Confirmed; Perplexity AI, Inc. documents a training control. Confirm whether it is enabled centrally or must be set by each user.

Practical risk: On consumer plans data is used to improve models unless you turn off the default-on 'AI data retention' toggle, and reporting alleges Perplexity shared conversational data with ad/tracking platforms (incl. in Incognito).

How to make a decision

Check the precise account tier, written contract and intended data before approving Perplexity. A security certification, DPA or setting can apply to only part of a vendor's service. Keep the source links with your supplier review and revisit them when the vendor changes its terms.
