| Retention | Until account deleted; 30 days to purgeShow detailsHide detailsPerplexity states it retains personal information as long as the account is active and removes it from its servers within 30 days of account deletion, which is requested through a form rather than a settings button. Incognito sessions expire within 24 hours and are not recoverable. Opting out of AI training applies only to data collected after the opt-out; data already collected for training cannot be removed. | Erased at guest-session end by defaultShow detailsHide detailsTwo distinct behaviours. In guest mode the conversation is erased when the session ends and nothing is persisted at all. With an account, chat history is saved only if you choose to keep it, and it is stored under zero-access encryption — Conversation Keys wrapped by a Master Key wrapped by your own PGP keypair, which is unlocked by your password. The operator states it stores no metadata such as timestamps, IP addresses, or chat context alongside either. |
