Where an uploaded file ends up, how long it stays, who can access it and what deletion means. With four approaches for files containing personal data.

In brief
  • An uploaded file goes in full to the provider and is stored there, even if your question concerns one paragraph.
  • In ChatGPT, a file can be retained separately from the conversation: deleting a chat does not automatically remove a stored file.
  • Whether a document is used for training depends on the subscription and the user's settings, not the file type.
