When you create a Substack profile, by default, posts and notes that you like will appear on your profile.
Tip: Posts you've liked may not appear if the post is on an invite-only publication or if you've chosen not to display the publication on your Substack profile.
How do I make my likes private?
On the web
1. Sign into your Substack account and click on your profile picture. Select Settings.
2. Scroll down to the Privacy section and slide the toggle to the left next to "Show likes on profile" . A grey toggle means that posts and notes you've liked will not be displayed on your Substack profile and your profile won't appear on the Likes list on a post.
On the Substack iOS app
1. Tap on your profile picture and then tap on the Settings icon at the bottom of the screen.
2. Scroll to the Privacy & Safety section.
3. In the Privacy section, tap the toggle next to "Show likes on profile" to disable this function.
4. Moving forward, posts or notes that you've liked will not appear on the Likes tab on your Substack profile.
