TikTok

Douyin was launched by ByteDance in Beijing, China in September 2016, originally under the name A.me, before rebranding to Douyin (抖音) in December 2016.[19][20] ByteDance planned on Douyin expanding overseas. The founder of ByteDance, Zhang Yiming, stated that "China is home to only one-fifth of Internet users globally. If we don’t expand on a global scale, we are bound to lose to peers eyeing the four-fifths. So, going global is a must."[21] Douyin was developed in 200 days and within a year had 100 million users, with more than one billion videos viewed every day.[22][23]

The app was launched as TikTok in the international market in September 2017.[24] On 23 January 2018, the TikTok app ranked first among free application downloads on app stores in Thailand and other countries.[25]

TikTok has been downloaded more than 130 million times in the United States and has reached 2 billion downloads worldwide,[26][27] according to data from mobile research firm Sensor Tower (those numbers exclude Android users in China).[28]

In the United States, celebrities, including Jimmy Fallon and Tony Hawk, began using the app in 2018.[29][30] Other celebrities, including Jennifer Lopez, Jessica Alba, Will Smith, and Justin Bieber joined TikTok as well and many other celebrities have followed.[31]

On 3 September 2019, TikTok and the U.S. National Football League (NFL) announced a multi-year partnership.[32] The agreement occurred just two days before the NFL's 100th season kick-off at Soldier Field, where TikTok hosted activities for fans in honor of the deal. The partnership entails the launch of an official NFL TikTok account, which is to bring about new marketing opportunities such as sponsored videos and hashtag challenges. In July 2020, TikTok, excluding Douyin, reported close to 800 million monthly active users worldwide after less than four years of existence.[33]

In May 2021, TikTok appointed Shou Zi Chew as their new CEO[34] who assumed the position from interim CEO Vanessa Pappas, following the resignation of Kevin A. Mayer on 27 August 2020.[35][36][37] On 3 August 2020, U.S. President Donald Trump threatened to ban TikTok in the United States on 15 September if negotiations for the company to be bought by Microsoft or a different "very American" company failed.[38] On 6 August, Trump signed two executive orders banning U.S. "transactions" with TikTok and WeChat to its respective parent companies ByteDance and Tencent, set to take effect 45 days after the signing.[39] A planned ban of the app on 20 September 2020[40][41] was postponed by a week and then blocked by a federal judge.[42][43][44][45] President Biden revoked the ban in a new executive order in June 2021.[46] The app has been banned by the government of India since June 2020 along with 223 other Chinese apps in view of privacy concerns.[47] Pakistan banned TikTok citing "immoral" and "indecent" videos on 9 October 2020 but reversed its ban ten days later.[48][49][50] In March 2021, a Pakistani court ordered a new TikTok ban due to complaints over "indecent" content.

In September 2021, TikTok reported that it had reached 1 billion users.[51] In 2021, TikTok earned $4 billion in advertising revenue.[52]

In October 2022, TikTok was reported to be planning an expansion into the ecommerce market in the US, following the launch of TikTok Shop in the United Kingdom. The company posted job listings for staff for a series of order fulfillment centers in the US and is reportedly planning to start the new live shopping business before the end of the year.[53]

On 9 November 2017, TikTok's parent company, ByteDance, spent nearly $1 billion to purchase musical.ly, a startup headquartered in Shanghai with an overseas office in Santa Monica, California, U.S.[54][55] Musical.ly was a social media video platform that allowed users to create short lip-sync and comedy videos, initially released in August 2014. It was well known, especially to the younger audience. Looking forward to leveraging the U.S. digital platform's young user base, TikTok merged with musical.ly on 2 August 2018 to create a larger video community, with existing accounts and data consolidated into one app, keeping the title TikTok.[56] This ended musical.ly and made TikTok a worldwide app, excluding China, since China already has Douyin.[55][57][58]

As of 2018, TikTok was available in more than 150 markets, and in 75 languages.[59][60] TikTok was downloaded more than 104 million times on Apple's App Store during the full first half of 2018, according to data provided to CNBC by Sensor Tower.[61]

After merging with musical.ly in August, downloads increased and TikTok became the most downloaded app in the U.S. in October 2018, which musical.ly had done once before.[62][63] In February 2019, TikTok, together with Douyin, hit one billion downloads globally, excluding Android installs in China.[64] In 2019, media outlets cited TikTok as the 7th-most-downloaded mobile app of the decade, from 2010 to 2019.[65] It was also the most-downloaded app on Apple's App Store in 2018 and 2019, surpassing Facebook, YouTube and Instagram.[66][67] In September 2020, a deal was confirmed between ByteDance and Oracle in which the latter will serve as a partner to provide cloud hosting.[68][69] Walmart intends to invest in TikTok.[70] This deal would stall in 2021 as newly elected President Biden's Justice Department put a hold on the previous U.S. ban under President Trump.[71][72][73] In November 2020, TikTok signed a licensing deal with Sony Music.[74] In December 2020, Warner Music Group signed a licensing deal with TikTok.[75][76][77] In April 2021, Abu Dhabi's Department of Culture and Tourism partnered with TikTok to promote tourism.[78] It came following the January 2021 winter campaign, initiated through a partnership between the UAE Government Media Office partnered and TikTok to promote the country's tourism.[79]

Since 2014, the first non-gaming apps[80] with more than 3 billion downloads were Facebook, WhatsApp, Instagram, and Messenger; all of these apps belong to Meta. TikTok was the first non-Facebook app to reach that figure. App market research firm Sensor Tower reported that although TikTok had been banned in India, its largest market, in June 2020, downloads in the rest of the world continue to increase, reaching 3 billion downloads in 2021.[81]

TikTok tends to appeal to younger users, as 41% of its users are between the ages of 16 and 24. These individuals are considered Generation Z or Gen Z and this audience is part of the generation that grew up in a world filled with internet.[100] Since they grew up surrounded by the internet, social media has become a part of their daily life. Among these TikTok users, 90% say they use the app daily.[101] TikTok's geographical use has shown that 43% of new users are from India.[102] As of the first quarter of 2022, there were over 100 million monthly active users in the United States and 23 million in the UK. The average user, daily, was spending 1 hour and 25 minutes on the app and opening TikTok 17 times.[103]

A variety of trends have risen within TikTok, including memes, lip-synced songs, and comedy videos. Duets, a feature that allows users to add their own video to an existing video with the original content's audio, have sparked many of these trends.

Trends are shown on TikTok's explore page or the page with the search logo. The page enlists the trending hashtags and challenges among the app. Some include #posechallenge, #filterswitch, #dontjudgemechallenge, #homedecor, #hitormiss, #bottlecapchallenge and more. In June 2019, the company introduced the hashtag #EduTok which received 37 billion views. Following this development, the company initiated partnerships with edtech startups to create educational content on the platform.[104]

The app has spawned numerous viral trends, Internet celebrities, and music trends around the world.[105] Many stars got their start on musical.ly, which merged with TikTok on 2 August 2018. These users include Loren Gray, Baby Ariel, Kristen Hancher, Zach King, Lisa and Lena, Jacob Sartorius, and many others. Loren Gray remained the most-followed individual on TikTok until Charli D’Amelio surpassed her on 25 March 2020. Gray's was the first TikTok account to reach 40 million followers on the platform. She was surpassed with 41.3 million followers. D'Amelio was the first to ever reach 50, 60, and 70 million followers. Charli D’Amelio remained the most-followed individual on the platform until she was surpassed by Khaby Lame on June 23, 2022. Other creators rose to fame after the platform merged with musical.ly on 2 August 2018.[106]

One notable TikTok trend is the "hit or miss" meme, which began from a snippet of iLOVEFRiDAY's song "Mia Khalifa." The song has been used in over four million TikTok videos and helped introduce the app to a larger Western audience.[107][108] TikTok also played a major part in making "Old Town Road" by Lil Nas X one of the biggest songs of 2019 and the longest-running number-one song in the history of the US Billboard Hot 100.[109][110][111]

TikTok has allowed many music artists to gain a wider audience, often including foreign fans. For example, despite never having toured in Asia, the band Fitz and the Tantrums developed a large following in South Korea following the widespread popularity of their 2016 song "HandClap" on the platform.[112] "Any Song" by R&B and rap artist Zico became number one on the Korean music charts due to the popularity of the #anysongchallenge, where users dance to the choreography of the song.[113] The platform has also launched many songs that failed to garner initial commercial success into sleeper hits, particularly during the COVID-19 pandemic.[114][115] However, it has received some criticism for not paying royalties to artists whose music is used on the platform.[108] In 2020, more than 176 different songs surpassed one billion video views on TikTok.[116]

In June 2020, TikTok users and K-pop fans "claimed to have registered potentially hundreds of thousands of tickets" for President Trump's campaign rally in Tulsa through communication on TikTok,[117] contributing to "rows of empty seats"[118] at the event. Later, in October 2020, an organization called TikTok for Biden was created to support then-presidential candidate Joe Biden.[119] After the election, the organization was renamed to Gen-Z for Change.[120][121]

TikTok has banned Holocaust denial, but other conspiracy theories have become popular on the platform, such as Pizzagate and QAnon (two conspiracy theories popular among the U.S. alt-right) whose hashtags reached almost 80 million views and 50 million views respectively by June 2020.[122] The platform has also been used to spread misinformation about the COVID-19 pandemic, such as clips from Plandemic.[122] TikTok removed some of these videos and has generally added links to accurate COVID-19 information on videos with tags related to the pandemic.[123]

On 10 August 2020, Emily Jacobssen wrote and sang "Ode To Remy," a song praising the protagonist from Pixar's 2007 computer-animated film named Ratatouille. The song rose to popularity when musician Daniel Mertzlufft composed a backing track to the song. In response, began creating a "crowdsourced" project called Ratatouille The Musical. Since Mertzlufft's video, many new elements including costume design, additional songs, and a playbill have been created.[124] On 1 January 2021, a full one-hour virtual presentation of Ratatouille the Musical premiered on the TodayTix. It starred Titus Burgess as Remy, Wayne Brady as Django, Adam Lambert as Emile, Chamberlin as Gusteau, Andrew Barth Feldman as Linguini, Ashley Park as Colette, Priscilla Lopez as Mabel, Mary Testa as Skinner, and André De Shields as Ego.

Several food trends have emerged on the platform, such as Dalgona coffee. Others include various social trends such as vabbing.

Another TikTok usage that corresponds with engagement and bonds people in society is the use of "challenges." These could be on any related topic such as dances or cooking certain meals. People see other people doing something that is trending and then it continues to spread until it is a viral trend that connects people from all over.[125]

While TikTok has primarily been used for entertainment purposes, TikTok may soon have another use, that of a job resource with the idea that prospective employment seekers would send in videos rather than traditional resumes. The form would most likely be a job search add-on. TikTok has had favorable results in the past with people using the site to find jobs and may be expanding that need, especially in the newer generations.[126]

Around mid-2020, some of the users on the platform started to differentiate between the "alt", "elite", or "deep" side of TikTok, seen as having more alternative and queer users, and the "straight" side of TikTok, seen as the mainstream.[127] Hyperpop music, including artists like 100 Gecs, became widely used on Alt TikTok, complementing the bright and colourful "Indie Kid" aesthetic.[128] Alt TikTok was also accompanied by memes with surrealist or supernatural themes (sometimes being described as cursed), such as videos with heavy saturation and humanoid animals.[129] One of the popular videos from Alt TikTok, gaining 18 million likes, shows a llama dancing to a cover of a song from a Russian commercial by the cereal brand Miel Pops, later becoming a viral audio.[130][131] Some Alt TikTok users personified brands and products in what some referred to as Retail TikTok.[129]

Another popular trend on TikTok is a large number of users putting the same image as their profile picture, known as a profile picture cult or a TikTok cult. Popular examples include "The Step Chickens" (started by the user @chunkysdead),[132] "The Hamster Cult" and the "Lana Del Rey Cult".[133]

TikTok has provided a platform for users to create content not only for fun but also for money. As the platform has grown significantly over the past few years, it has allowed companies to advertise and rapidly reach their intended demographic through influencer marketing.[134] The platform's AI algorithm also contributes to the influencer marketing potential, as it picks out content according to the user's preference.[135] Sponsored content is not as prevalent on the platform as it is on other social media apps, but brands and influencers still can make as much as they would if not more in comparison to other platforms.[135] Influencers on the platform who earn money through engagement, such as likes and comments, are referred to as "meme machines."[134]

In 2021, The New York Times reported that viral TikTok videos by young people relating the emotional impact of books on them, tagged with the label "BookTok," significantly drove sales of literature. Publishers were increasingly using the platform as a venue for influencer marketing.[136]

In October 2020, the e-commerce platform Shopify added TikTok to its portfolio of social media platforms, allowing online merchants to sell their products directly to consumers on TikTok.[137]

Some small businesses have used TikTok to advertise and to reach an audience wider than the geographical region they would normally serve. The viral response to many small business TikTok videos has been attributed to TikTok's algorithm, which shows content that viewers at large are drawn to, but which they are unlikely to actively search for (such as videos on unconventional types of businesses, like beekeeping and logging).[138]

In 2020, digital media companies such as Group Nine Media and Global used TikTok increasingly, focusing on tactics such as brokering partnerships with TikTok influencers and developing branded content campaigns.[139] Notable collaborations between larger brands and top TikTok influencers have included Chipotle's partnership with David Dobrik in May 2019[140] and Dunkin' Donuts' partnership with Charli D'Amelio in September 2020.[141]

Popular TikTok users have lived collectively in collab houses, predominantly in the Los Angeles area.[142]

Iranians cannot access TikTok because of both TikTok rules and Iranian censorship.[143]

The Indian Government banned TikTok along with 58 other mobile apps with Chinese developers or investors, including WeChat, UC Browser and PUBG on 29 June 2020.[144][145] The Ministry of Electronics and Information Technology released a statement saying the apps were "prejudicial to sovereignty and integrity of India, defence of India, security of state and public order."[146][145] It was extended to 47 other apps which the ministry claimed were clones or variants of the banned apps.[145] The ban on TikTok and the 58 other apps was made permanent in January 2021.[147] In February 2021, TikTok announced that due to the ban it will be forced to lay off over 2,000 employees in India.[148]

In June 2021, Law and Life Foundation, a human rights organization, issued a legal notice to the Bangladeshi government that sought the prohibition of “dangerous and harmful" applications such as TikTok, PUBG, and Free Fire, but failed to obtain a response. Soon thereafter, Law and Life Foundation’s lawyers filed a petition with the High Court, sharing the organization’s concerns. In August 2020, the High Court encouraged the Bangladeshi government to prohibit “dangerous and harmful” applications such as TikTok, PUBG, and Free Fire to “save children and adolescents from moral and social degradation.”[149]

Recently more than 2.6 million videos were removed from Bangladesh, according to its recently released Community Guidelines Report for Q4 2021 (October–December 2021). According to the report, Bangladesh ranked 7th worldwide for the largest volume of videos taken down for Community Guidelines violations between October 1, 2021, to December 30, 2021.[150]

On 6 August 2020, then U.S. President Donald Trump signed an order[151][152] which would ban TikTok transactions in 45 days if it was not sold by ByteDance. Trump also signed a similar order against the WeChat application owned by the Chinese multinational company Tencent.[153][41]

On 14 August 2020, Trump issued another order[154][155] giving ByteDance 90 days to sell or spin off its U.S. TikTok business.[156] In the order, Trump said that there is "credible evidence" that leads him to believe that ByteDance "might take action that threatens to impair the national security of the United States."[157] Donald Trump was concerned about TikTok being a threat because TikTok's parent company was rumored to be taking United States user data and reporting it back to Chinese operations through the company ByteDance.[158] As of 2021, there is still the fear that TikTok is not protecting the privacy of its users and may be giving their data away.[159]

TikTok considered selling the American portion of its business and held talks with companies including Microsoft, Walmart, and Oracle.[160]

On 18 September, TikTok filed a lawsuit, TikTok v. Trump. On 23 September 2020, TikTok filed a request for a preliminary injunction to prevent the app from being banned by the Trump administration.[161] U.S. judge Carl J. Nichols temporarily blocked the Trump administration order that would effectively ban TikTok from being downloaded in U.S. app stores starting midnight on 27 September 2020. Nichols allowed the app to remain available in the U.S. app stores but declined to block the additional Commerce Department restrictions that could have a larger impact on TikTok's operations in the U.S. These restrictions were set to take place on 12 November 2020.[162]

Three TikTok influencers filed a lawsuit, Marland v. Trump.[163] On 30 October, Pennsylvania judge Wendy Beetlestone ruled against the Commerce Department, blocking them from restricting TikTok.[163] On 12 November, the Commerce Department stated that it would obey the Pennsylvania ruling and that it would not try to enforce the restrictions against TikTok that had been scheduled for 12 November.[163]

The Commerce Department appealed the original ruling in TikTok v. Trump. On 7 December, Washington D.C. district court judge Carl J. Nichols issued a preliminary injunction against the Commerce Department, preventing them from imposing restrictions on TikTok.[164][165][166]

In June 2021, new president Joe Biden signed an executive order revoking the Trump administration ban on TikTok, and instead ordered the Secretary of Commerce to investigate the app to determine if it poses a threat to U.S. national security.[167]

In June 2022, reports emerged that ByteDance employees in China could access US data and repeatedly accessed the private information of TikTok users,[168][169][170] TikTok employees were cited saying that "everything is seen in China," while one director claimed a Beijing-based engineer referred to as a "Master Admin" has "access to everything."[168][171][172]

Following the reports, TikTok announced that 100% of its US user traffic is now being routed to Oracle Cloud, along with their intention to delete all US user data from their own data centers.[169][171] This deal stems from the talks with Oracle instigated in September 2020 in the midst of Trump's threat to ban TikTok in the US.[173][174][172]

In June 2022, FCC Commissioner Brendan Carr called for Google and Apple to remove TikTok from their app stores, citing national security concerns, saying TikTok "harvests swaths of sensitive data that new reports show are being accessed in Beijing."[175][168]

However, back in March 2022, Bytedance and Oracle negotiated Oracle to take over TikTok's US data storage. After BuzzFeed said China-based employees may have access to US private data, TikTok responded that all US private data are being stored in Oracle's servers.[176] In June 2022, TikTok said that it was moving all of the data produced by its American users through servers controlled by Oracle and it will not expose the personal information of Americans to the Chinese government.[177]

In October 2022, a Forbes report claimed that the ByteDance team planned to surveil individual American citizens for undisclosed reasons. TikTok denied these claims in a series of tweets, saying that this report lacked "both rigor and journalistic integrity."[178][179]

TikTok has been intermittently blocked in Indonesia on different bases.[180][181]

On 11 October 2020, Pakistan became the next country to ban the social media platform after not complying with issues regarding the content on the platform brought up by their government.[182] TikTok representatives have spoken with Pakistani officials in hopes of building better relations and allowing the people of Pakistan to create on the platform.[182]

In April 2022, a spokesman for the Taliban government stated that the app will be banned for 'misleading the younger generation' and that TikTok's content was 'not consistent with Islamic laws'.[183]

There are concerns that some users may find it hard to stop using TikTok.[184] In April 2018, an addiction-reduction feature was added to Douyin.[184] This encouraged users to take a break every 90 minutes.[184] Later in 2018, the feature was rolled out to the TikTok app. TikTok uses some top influencers such as Gabe Erwin, Alan Chikin Chow, James Henry, and Cosette Rinab to encourage viewers to stop using the app and take a break.[185]

Many were also concerned with the app affecting users' attention spans due to the short-form nature of the content. This is a concern as many of TikTok's audience are younger children, whose brains are still developing.[186] TikTok executives & representatives have noted and made aware to advertisers on the platform that users have poor attention spans. With a large amount of video content, nearly 50% of users find it stressful to watch a video longer than a minute and a third of users watch videos at double speed.[103]

In June 2022, TikTok introduced the ability to set a maximum uninterrupted screen time allowance, after which the app blocks off the ability to navigate the feed. The block only lifts after the app is exited and left unused for a set period of time. Additionally, the app features a dashboard with statistics on how often the app is opened, how much time is spent browsing it and when the browsing occurs.[187]

Some countries have shown concerns regarding the content on TikTok, as their cultures view it as obscene, immoral, vulgar, and encouraging pornography. There have been temporary blocks and warnings issued by countries including Indonesia,[180] Bangladesh,[181] India,[188] and Pakistan[189][190] over the content concerns. In 2018, Douyin was reprimanded by Chinese media watchdogs for showing "unacceptable" content.[191]

On 27 July 2020, Egypt sentenced five women to two years in prison over TikTok videos. One of the women had encouraged other women to try and earn money on the platform, another woman was sent to prison for dancing. The court also imposed a fine of 300,000 Egyptian pounds (UK£14,600) on each defendant.[192]

Concerns have been voiced regarding content relating to, and the promotion and spreading of, hateful words and far-right extremism, such as anti-semitism, racism, and xenophobia. Some videos were shown to expressly deny the existence of the Holocaust and told viewers to take up arms and fight in the name of white supremacy and the swastika.[193] As TikTok has gained popularity among young children,[194] and the popularity of extremist and hateful content is growing, calls for tighter restrictions on their flexible boundaries have been made. TikTok has since released tougher parental controls to filter out inappropriate content and to ensure they can provide sufficient protection and security.[195]

A viral TikTok trend known as "devious licks" involves students vandalizing or stealing school property and posting videos of the action on the platform. The trend has led to increasing school vandalism and subsequent measures taken by some schools to prevent damage. Some students have been arrested for participating in the trend.[196][197] TikTok has taken measures to remove and prevent access to content displaying the trend.[198]

The Wall Street Journal has reported that doctors experienced a surge in reported cases of tics, tied to an increasing number of TikTok videos from content creators with Tourette syndrome. Doctors suggested that the cause may be a social one as users who consumed content showcasing various tics would sometimes develop tics of their own.[199]

In March 2022, the Washington Post reported that Facebook owner Meta Platforms had paid Targeted Victory—a consulting firm backed by supporters of the U.S. Republican Party—to coordinate lobbying and media campaigns against TikTok to portray it as "a danger to American children and society", primarily to counter criticism of Facebook's own services. This included op-eds and letters to the editor in regional publications, the amplification of "dubious local news stories citing TikTok as the origin of dangerous teen trends" (such as the aforementioned "devious licks", and an alleged "Slap a Teacher" challenge), including those whose initial development actually began on Facebook, and the similar promotion of "proactive coverage" of Facebook corporate initiatives.[200]

Numerous examples of White TikTokers appropriating content that was created initially by Black content creators have been noted on the platform. In June 2021, the New York Times published an investigation into the practice as part of the Hulu documentary, Who Gets to be an Influencer?[201]

In July 2021, after Megan Thee Stallion released "Thot Shit," there was a general strike by Black TikTokers who refused to make dances to it as they normally would, in protest of the inequity of compensation for Black creators and white creators who appropriated the Black creators' content.[202]

In January 2020, left-leaning media watchdog Media Matters for America said that TikTok hosted misinformation related to the COVID-19 pandemic despite a recent policy against misinformation.[203] In April 2020, the government of India asked TikTok to remove users posting misinformation related to the COVID-19 pandemic.[204] There were also multiple conspiracy theories that the government is involved with the spread of the pandemic.[205] As a response to this, TikTok launched a feature to report content for misinformation.[206]

To combat misinformation in the 2022 midterm election in the US, TikTok announced a midterms Elections Center available in-app to users in 40 different languages. TikTok partnered with the National Association of Secretaries of State to give accurate local information to users.[207]

Based on NewsGuard's Misinformation Monitor published in September 2022, the search feature on TikTok surfaces misinformation in 20% of the cases. The fact-checking organisation analyzed 540 videos and found 105 to contain "false or misleading claims."[208] The questionable videos included harmful misleading information about various topics, including homemade recipes for hydroxychloroquine and abortion, 2020 US election integrity and the death toll of the war in Ukraine.

TikTok's censorship policy has been criticized as non-transparent.[209] Criticism of leaders such as Xi Jinping, Vladimir Putin, Donald Trump, Barack Obama, Mahatma Gandhi[210] and Recep Tayyip Erdoğan[211] has been suppressed by the platform, as well as information relating to the Xinjiang internment camps and the Uyghur genocide.[212][213] Internal documents have revealed that moderators suppress posts created by users deemed "too ugly, poor, or disabled" for the platform, and censor political speech on livestreams.[214][215][216] TikTok moderators have also blocked content that could be perceived as being positive towards LGBT people.[211][217]

In response to the 2022 Russian invasion of Ukraine, TikTok banned new Russian posts and livestreams.[218][219][220] However, a study by Tracking Exposed found out that TikTok had blocked all non-Russian content but has continued to host old videos uploaded by Russia-based accounts and permitted Russian state media to continue posting, described as establishing a "splinternet" within a global social media platform.[221] TikTok's vague censorship has permitted pro-Kremlin news but blocked foreign accounts and critics of the war, as a result "Russians are left with a frozen TikTok, dominated by pro-war content".[222][223]

In October 2019, TikTok removed about two dozen accounts that were responsible for posting ISIL propaganda on the app.[224][225]

Privacy concerns have also been brought up regarding the app.[226][227] In its privacy policy, TikTok lists that it collects usage information, IP addresses, a user's mobile carrier, unique device identifiers, keystroke patterns, and location data, among other data.[228][229] Web developers Talal Haj Bakry and Tommy Mysk said that allowing videos and other content to be shared by the app's users through HTTP puts the users' data privacy at risk.[230]

In January 2020, Check Point Research discovered a security flaw in TikTok which could have allowed hackers access to user accounts using SMS.[231] In February, Reddit CEO Steve Huffman criticised the app, calling it "spyware," and stating "I look at that app as so fundamentally parasitic, that it's always listening, the fingerprinting technology they use is truly terrifying, and I could not bring myself to install an app like that on my phone."[232][233] Responding to Huffman's comments, TikTok stated, "These are baseless accusations made without a shred of evidence."[228] Wells Fargo banned the app from its devices due to privacy and security concerns.[234]

In May 2020, the Dutch Data Protection Authority announced an investigation into TikTok in relation to privacy protections for children.[235][236] In June 2020, the European Data Protection Board announced that it would assemble a task force to examine TikTok's user privacy and security practices.[237]

In August 2020, The Wall Street Journal reported that TikTok tracked Android user data, including MAC addresses and IMEIs, with a tactic in violation of Google's policies.[238][239] The report sparked calls in the U.S. Senate for the Federal Trade Commission (FTC) to launch an investigation.[240]

In June 2021, TikTok updated its privacy policy to include a collection of biometric data, including "faceprints and voiceprints."[241] Some experts reacted by calling the terms of collection and data use "vague" and "highly problematic."[242] The same month, CNBC reported that former employees had stated that "the boundaries between TikTok and ByteDance were so blurry as to be almost non-existent" and that "ByteDance employees are able to access U.S. user data" on TikTok.[243]

In October 2021, following the Facebook Files and controversies about social media ethics, a bipartisan group of lawmakers also pressed TikTok, YouTube, and Snapchat on questions of data privacy and moderation for age-appropriate content. The New York Times reported, "Lawmakers also hammered [head of U.S. policy at TikTok] Mr. Beckerman about whether TikTok’s Chinese ownership could expose consumer data to Beijing," stating that "Critics have long argued that the company would be obligated to turn Americans’ data over to the Chinese government if asked."[244] TikTok told U.S. lawmakers it does not give information to China's government. TikTok's representative stated that TikTok's data is stored in the U.S. with backups in Singapore.
