ConductAtlas Analysis

Why it matters (compliance & governance perspective)

The clause establishes a data controller relationship where Creators assume independent responsibility for personal information provided through publication interactions. This operationally means Substack's privacy commitments do not extend to Creator-controlled processing, requiring users to reference separate Creator privacy policies to understand information handling practices.

Medium May 5, 2026

Substack now discloses that it shares account identifiers, such as email addresses and usernames, with trusted industry child safety organizations to detect and prevent online child sexual exploitation and abuse. The policy also establishes that Substack will respond to privacy rights requests within one month, or up to three months for complex requests, providing more certainty about response timelines. Additionally, the policy clarifies that direct message recipients may retain messages even if you request deletion or delete your account, which is now explicitly stated rather than implied.

Medium Apr 19, 2026

The updated policy no longer commits to responding to privacy rights requests within one month or within three months for complex requests. This removes a procedural timeline that previously bound Substack's response obligations. Additionally, the explicit disclosure that Substack shares account identifiers with child safety consortia to detect online child sexual exploitation has been removed from the policy, though the practice itself is not stated to have ended. The direct message retention language is now framed more directly: recipients may retain messages even if you request deletion or close your account.

Please note that Creators control their own publications; accordingly, when you interact with a Creator's publication in a way that requires your personal information, including when commenting on a publication that you have not subscribed to, that personal information is provided directly to the Creator. ... This Privacy Policy does not apply to any processing of your Personal Information by Substack as a data processor on behalf of a Creator.
