Substack's updated privacy policy removes language describing a one-month response timeline for certain privacy rights requests and eliminates explicit disclosure about sharing account identifiers with child safety consortia. The policy now states recipients of direct messages may keep those messages even if deleted or the account is removed, without the prior qualifying language that noted this despite platform functionality. The updated terms no longer specify response deadlines or detail the child safety data sharing practice.

2 protections removed

Consumers: Substack no longer commits to a specific timeframe for responding when you ask to access, correct, or delete your data.

Consumers: The policy no longer explicitly describes the practice of sharing identifiers with child safety organizations.

What this means for you

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.
