When you signed up for Tumblr, we asked you to give your age. We use your age for two reasons:
- You must be at least 13 years old to use Tumblr. As stated in our Terms of Service, “We're serious: it's a hard rule, based on U.S. federal and state legislation. ‘But I’m, like, 12.9 years old!’ you plead. Nope, sorry. If you're younger than 13, don't use Tumblr. Ask your parents for a Playstation 4, or try books.”
- You must be at least 18 years old to turn off Safe Mode. If you’re under the age of 18, Safe Mode is enabled for you and you can’t disable it.
Since we go by your birth year and not your exact birthday, you may need to wait until the January 1 of the following calendar year before you can disable Safe Mode. For example, if you said you were 14 when you registered in 2015, you'll have to wait until January 1, 2019. Note that if you registered before your birthday that year, your age will be rounded down in our system.
Your age is calculated according to the age you gave during signup, and it’s not possible to edit that age.
