  • Store, reproduce, and display your User Content
  • Create derivative works for the purpose of providing the Service
  • Distribute your User Content to authorized collaborators

This license terminates when you delete your content or account. Note that we use a "soft delete" approach where deleted content is marked as deleted but may be retained in our database for backup and recovery purposes. Deleted content is not accessible through the application interface.
