This article is about our consumer products such as Claude Free, Pro, Max and when accounts from those plans use Claude Code. For our commercial products such as Claude for Work and the Anthropic API, see here.
Anthropic retains your personal data for as long as reasonably necessary for the purposes and criteria outlined in our Privacy Policy.
Standard Retention Timeframe
Controlling Your Chats
You control your chats with Claude and can delete your conversations at any time. When you delete a conversation it’s:
Removed from your chat history immediately
Deleted from our back-end storage systems within 30 days
If You Allow Us to Use Your Data to Improve Claude
If you allow us to use your chats or coding sessions to improve Claude, we may retain your data in a de-identified format for up to 5 years in our model training pipelines. This retention period only applies to new or resumed chats after the model training setting has been enabled. You can learn more about how our models are trained here.
You can change your privacy settings with respect to model training at any time following these steps here.
If you decide to turn off the model improvement setting, we will not use your previous or new chats or coding sessions for future model training. Additionally, if you delete a chat from your chat history, it will not be used to train future models. Your data will still be included in model training runs that are already in progress, or in models that have been trained.
Your Incognito chats are not used to improve Claude, even if you have enabled Model Improvement in your Privacy Settings. Learn more about Incognito chats.
Usage Policy Violations
We retain inputs and outputs for up to 2 years and trust and safety classification scores for up to 7 years if your chat or session is flagged by our trust and safety classifiers as violating our Usage Policy.
Feedback Data
Where you have provided feedback to us (e.g. by submitting feedback through our thumbs up/down button or sent bug reports), we retain data associated with that submission for 5 years. Learn more.
Additional Information
We may anonymize or de-identify your personal data for research or statistical purposes, in which case we may retain this information for longer.
In all cases, we may retain chats and coding sessions as required by law, to resolve disputes, or as necessary to combat violations of our Usage Policy.
