When you sign up for Tumblr, you provide us with your age. We use this information in a couple of different ways.
First of all, if you’re a resident of the European Union or the United Kingdom, you must be at least 16 years old in order to use Tumblr. In all other regions, you must be at least 13 years old to use Tumblr. No exceptions.
Additionally, you must be at least 18 years old to view blogs that have been either self-flagged or flagged by us as “explicit” per our old policy (before December 17, 2018). While some of the content on these blogs may now be in violation of our policies and will be actioned accordingly, the blog owners may choose to post content that is within our policies in the future.
If you are under 18, you will still not be allowed to click through to see the content of these blogs.
We are unable to update your age in our system.
