When you sign up for Tumblr, we determine your year of birth and record it in our database. We use this information in a couple of different ways.
First of all, if you’re a resident of the European Union, as of May 25, 2018, you must be at least 16 years old (or the lower age that your country has provided for you to consent to the processing of your personal data) in order to use Tumblr. In a number of European countries, legislation to change the minimum age is pending. We are carefully monitoring this legislation in case the minimum age in your country changes. 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 calculate your age according to your year of birth. To figure out if you’re 18, our system takes your birth year and subtracts it from the current year. So to be considered “over 18” by our system in 2019, you need to have indicated that your birth year was 2001 or earlier when you signed up.
We are unable to update your age in our system.
