Consumer impact (what this means for users)

This provision establishes that content posted to Substack is licensed to the platform on terms that survive account deletion, meaning Substack may retain the ability to use, modify, and reproduce that content after a user leaves the service. The agreement separately acknowledges that publicly posted content may remain viewable after account closure to the extent it was copied or stored by other users.

What you can do

⚠️ These actions may provide transparency or partial mitigation but may not fully address the underlying issue. Effectiveness varies by jurisdiction and individual circumstances.
  • Delete Your Data
    Navigate to your account settings page at substack.com/account/settings and select the account deletion option. Note that publicly posted content may remain accessible after deletion as stated in the terms.
