Where Perplexity's pages were unclear

Where the pages were unclear

  • No retention period is stated for regular threads in an active account; they appear to stay until you delete them or the account.
  • Incognito: one page says incognito searches are never stored, another says incognito sessions are kept for 24 hours and then expire. Neither says whether incognito chats are excluded from training.
  • Export: the file format and contents are not stated.
  • The exact label of the account delete button was not shown; the page only says the option is at the bottom of the account details page.
  • A note on the memory page says a log of cleared memories may be kept for up to 30 days; it was described in an Enterprise context and it is unclear if it applies to consumers.
