The answer

Yes, according to Anthropic's own pages.

Anthropic says a deleted chat leaves your history immediately and is removed from back-end storage within 30 days, barring legal or safety holds.

The steps

How to do it in Claude

  1. 1.Your chats, until you delete them. A deleted chat leaves your history right away and is removed from back-end systems within 30 days.
  2. 2.If you let Anthropic train on your chats, it may keep them in a de-identified form for up to 5 years. If you do not, the standard period is 30 days.
  3. 3.Feedback you send, like a thumbs up or down, is kept for 5 years, whatever your training setting.
  4. 4.Chats flagged by safety systems can be kept for up to 2 years, and their safety scores for up to 7 years.
  5. 5.Memory: Claude saves what it learns about you as topics. Memory is on by default for Free, Pro and Max. Deleting a chat does not remove memories made from it.
  6. 6.Your projects and account details stay until you delete them or your account.

The 5-year period applies to new or resumed chats after you allow training.
