With so many social networks to keep track of, it's not surprising if your kid's obsession with the Tik Tok app leaves you scratching your head. So what is it exactly?

Tik Tok is a free social media app that lets you watch, create, and share videos -- often to a soundtrack of the top hits in music -- right from your phone. It was originally available as musical.ly in the U.S. but was rebranded when the two apps merged in August 2018. With more than 100 million users, Tik Tok is incredibly popular, owing in part to its slick mash-up of features from other kid favorites. As with the lip-synching app Dubsmash, users can watch and record videos of themselves lip-synching to popular music and sound bites. As they did on the now-defunct Vine, kids can create short, shareable videos ranging from funny to serious. And just like YouTube, Tik Tok is an interactive world of videos that lets you connect with friends and admirers through likes, comments, and even duets.

Tik Tok - including musical.ly even spawns its own celebrities. Almost overnight, musical.ly sensations like Baby Ariel and Jacob Sartorius have gained internet fame, especially with kids and teens.

But with so much information out there, it can be a challenge for parents to know if it's really safe. While Tik Tok videos are mostly harmless, creative fun, there are real concerns about kids using the app. As with any social network, you have to use privacy settings to limit how much information you and your kids are sharing. Kids can post stuff without reviewing or editing it first. There have even been reports of online predators using the app to target younger users.

Read Common Sense Media's full review of Tik Tok - including musical.ly, and help your kids use it safely with answers to parents' most frequently asked questions below.

What is Tik Tok - including musical.ly?

Tik Tok is a social network for sharing user-generated videos, mostly of people lip-synching to popular songs. It was originally called musical.ly (pronounced MU-zik-lee). Users can create and upload their own videos where they lip-synch, sing, dance, or just talk. You can also browse and interact with other users' content, which covers a wide range of topics, songs, and styles.

How safe is Tik Tok - including musical.ly?

Using any social network can be risky, but it's possible for kids to safely use the app with adult supervision (and a private account). When you sign up for Tik Tok, your account is public by default, meaning anyone can see your videos, send you direct messages, and use your location information. Parents should make sure to turn on all privacy settings for accounts kids are using, so only people you know can interact with your videos or message you on the app. 

How does Tik Tok - including musical.ly work?

Tik Tok users sign up with a phone number, an email address, Facebook, or Instagram. Once logged in, you can search popular creators, categories (comedy, animals, sports), and hashtags to find videos. Or you can use your phone contacts or social media followers to find friends already on the app. Many kids on Tik Tok like to create videos, but plenty of people don't post themselves -- they just use the app to find and follow content creators.

Is Tik Tok - including musical.ly appropriate for kids?

Because of Tik Tok's emphasis on popular music, many videos include swearing and sexual lyrics, so it may not be age-appropriate for kids to use on their own. It's also easy to find people wearing revealing clothing and dancing suggestively, although Tik Tok won't let you search for objectionable content such as "sex" or "porn." If you supervise your kids and stick to songs you already know from the radio, Tik Tok can be a kid-friendly experience.

What age is Tik Tok - including musical.ly recommended for?

Common Sense recommends the app for age 16+ mainly due to the privacy issues and mature content. Tik Tok requires that users be at least 13 years old to use the app and that anyone under the age of 18 must have approval of a parent or guardian -- but there are plenty of young tween users. If your younger kid or tween wants to use the app, the account should belong to an adult who can monitor what younger users are browsing and sharing.

How are Tik Tok - including musical.ly and live.ly related?

When Tik Tok merged with musical.ly, the developers shut down live.ly and directed livestreamers to LiveMe, a different live video app. Musical.ly and live.ly were created by the same developers and linked together. But where musical.ly was based on recorded videos, live.ly was a live-streaming service, which can be a riskier option for kids and teens. You could use one account for both services and move between the two apps depending on the features you want to use, but this is no longer available within Tik Tok. 

How can you make your Tik Tok - including musical.ly account private?

To make your Tik Tok account private, go to your profile page and select the three-dot icon in the top-right corner. Select Privacy and Safety. There, toggle the switch for "Private Account." You can also edit who can send you comments and direct messages, and who can do a duet with you.

How do I delete a Tik Tok - including musical.ly video?

To delete a Tik Tok video that you have posted to your account, select the video you want to delete from your profile. From there, tap the "..." icon in the bottom-right corner and select Delete or the trash can icon. You will be asked if you are sure you want to delete the video. Then it will be removed from your profile.

How can I delete a Tik Tok - including musical.ly account?

To delete a Tik Tok account, go to your profile, then select the "..." icon in the top-right corner. Select Manage My Account. From there, you must add a phone number if you haven't already. This must be a working number, as they will text you a code to verify the number and later to verify deleting the account. Once you've added a phone number, an option at the bottom of the Manage My Account menu will appear, asking, "Thinking about removing your account?" Tap the phrase, which will lead you to a new page prompting you to enter a verification code. Choose "Send Code" to receive a text message with the verification code. Enter the number, then select Continue. You will be given information on what is entailed in deleting the account. Choose Continue once again for a final confirmation that you want to delete your account, then tap Delete Account. 

How can I use Tik Tok - including musical.ly with my kids?

You can provide a buffer between kids and iffy content by watching with your kids and making videos together. Offer to hold the camera or turn it around to do a selfie duet. You can post it or save it as "private" so only you can see. The app also lets you share videos by email, text, or other social media where you can better control who sees it, so kids can perform for friends and relatives instead of a wider network of people.

How do you do a duet on Tik Tok - including musical.ly?

Tik Tok has a feature that allows two users who aren't in the same place to perform a duet. Both users must follow each other to make it work. One user creates and posts a video, and then a mutual follower can tap the "..." icon at the bottom right of the video and select "start duet now!" The second user can then lip-synch along with the first person, either swapping back and forth or in a split screen.

How can I monitor my kid's activity on Tik Tok - including musical.ly?

Other than blocked search terms, there's no way to filter out content on Tik Tok, so kids using the app on their own might come across age-inappropriate videos. Parents can and should share an account with kids under the age of 13. For older kids, ask about their favorite video creators and get to know their videos (with or without your kid). Also, take the time to regularly look at the most popular songs, videos, and challenges.

What if my kid wants to get famous on Tik Tok - including musical.ly?

While the safest way to use Tik Tok is with a private account, the social nature of the app and the rapid success of its stars might have your kids begging to set it to public. There's huge enticement to get famous, which could encourage kids to do things they wouldn't normally do to get a larger audience. They may also become obsessed with "likes" and virtual approval. Encourage and model safe behavior, and make sure to set limits on the type of information your kid shares.

Thanks for this article. My daughter is using Tik Tok and wants to make her account public. Her profile doesn't have any identifying information, but I'm trying to determine how location info might be exposed by this app. It says in the article that public accounts allow users to "use your location information" by default, but I can't find any settings in the app related to "location," nor can I find any info on the web about this. It seems to me that the only way a user could share their location would be by literally saying in their profile bio "I live in Los Angeles" or something. Does anyone know about this?
