You agree to the privacy policy below, and the Privacy Policy for Substack, the technology provider.

This is not an official privacy policy, but I wanted to be transparent about what I do with the data that Substack shares with me.

Subscriptions: if you subscribe, Substack shows me your email address. I do not sell, share, or monetize this information, but I periodically back up the subscriber list. This is so that if platform takes a turn for the worse, I can still reach you and possibly migrate to another newsletter service.

Likes, shares, comments: on Substack, all these activities are public and are linked to your profile; that profile may be identifiable depending on what you opted to share. The usual internet rules apply: while you can edit or delete public posts, it’s not always possible to put toothpaste back in the tube.

Activity metrics: the platform shows me stats about article views, link clicks, and so forth. I occasionally look at the info to understand which articles appeal to readers, but I am not pawning off any of it.

Third-party integrations: some articles embed videos that are hosted on Vimeo; their business model is to charge me money, not to show you ads. As for outgoing links: I try to link to high-quality sites, but I offer no guarantees.

Beyond this, Substack corporate privacy policy applies. In common with most online platforms, the policy is fairly open-ended — but as with Vimeo, they currently make money by charging for a specific service, not following you around.
