Tumblr enables you to share all of the posts you've liked on a separate page, and many Tumblr themes also include a section for a widget that displays your likes on your blog's layout. If you'd like to remove this section and prevent other users from seeing your likes, you must toggle the feature off and remove the Likes widget on your layout.

Step 1

Log in to your Tumblr account, and then click the gear icon on your Dashboard to visit your primary account's settings page.

Step 2

Click the "Dashboard" tab in the main menu, and then toggle the switch next to "Share Posts I Like" in the Likes section to "Off." Tumblr automatically saves your preferences.

Step 3

Click the Home icon on your Dashboard, and then select the "Customize" tab in the main menu to visit the customization settings for your blog's layout.

Step 4

Scroll down your customization settings to see if your theme has a toggle switch to display and hide the Likes widget on your blog; if it does, toggle the switch to "Off."

Step 5

Click the "Save" button, and then click "Exit" to return to your Dashboard.
