Substack

The policy clearly outlines how users can request deletion (via email or postal mail) and explicitly mentions the rights to access, update, and delete data for EEA/UK residents. It does not state any explicit barriers such as excessive identity verification, fees, or extended timelines. The availability of email as a contact channel, alongside postal mail, means physical mail is not a required barrier. The absence of self-service deletion is not considered a barrier according to the scoring guide.
