How long can I keep my subdomain?

If a publication remains inactive for more than 6 months, we may reassign its subdomain ([name].substack.com). 

If a publication is inactive for more than three months (but less than six) and its associated subdomain is requested by another publisher, our policy is to ask the publisher for permission to reassign the subdomain to the requester. 

Subdomains may be reassigned at any time at our discretion if we believe that the use of the subdomain poses a security or other risk to our platform, employees, or users.

Please note that in order to keep any subdomain, activity on your publication should be authentic. We reserve the right to use our discretion when evaluating whether content has been published for the sole purpose of domain squatting.
