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.
View change record →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.

"Prospective sellers or buyers: We may share and/or transfer customer information in connection with the sale or merger of our business or assets (subject to local laws). Also, if we go out of business, enter bankruptcy, or go through some other change of control.Excerpt from Substack's Privacy Policy
1. REGULATORY LANDSCAPE: This provision engages GDPR Article 6 lawful basis requirements for data transfers in M&A contexts, as well as FTC guidance on the treatment of customer data in business transactions. CCPA requires disclosure of the categories of third parties to whom personal information is transferred. State AG offices have historically taken action regarding consumer data transfers in bankruptcy or acquisition contexts. 2. GOVERNANCE EXPOSURE: Low to Medium. Business transfer data sharing provisions are standard across the industry, but the absence of specific user notification procedures or data use limitation commitments for acquiring entities is a due diligence consideration. 3. JURISDICTION FLAGS: EU/EEA users may have heightened exposure if a business transfer results in personal data being transferred to an entity outside the adequacy framework. California users have CCPA rights that may apply to notification in the event of a business transfer affecting their data. 4. CONTRACT AND VENDOR IMPLICATIONS: Organizations using Substack for business-critical functions should be aware that platform ownership and data governance practices could change in the event of a merger, acquisition, or bankruptcy without specific notification requirements established in this policy. 5. COMPLIANCE CONSIDERATIONS: Compliance teams should monitor for Substack corporate transactions that could trigger data transfer to new entities and assess whether updated data processing agreements or transfer impact assessments would be required in that event.
