The Saudi Central Bank (SAMA) has prohibited local banks from using instant messaging applications like WhatsApp for customer communication. The organization reported a massive drop-off in traffic for the blocked services, though the country’s government made no official statements about the block. In August 2021, the digital rights organization Access Now reported that WhatsApp along with several other social media apps was being blocked in Zambia for the duration of the general election. The ban was prompted by concerns of US authorities potentially accessing user data for such apps because of the CLOUD Act. In December 2021, the Swiss army banned the use of WhatsApp and several other non-Swiss encrypted messaging services by army personnel.
In January 2022, an unsealed surveillance application revealed that WhatsApp started tracking seven users from China and Macau in November 2021, based on a request from US DEA investigators. However, the company did not reveal names of the end users, which according to a research by Citizen Lab include, Saudi Arabia, Bahrain, Kazakhstan, Morocco, Mexico and the United Arab Emirates. In November 2019, WhatsApp released a new privacy feature that let users decide who can add them to groups. On April 5, 2016, WhatsApp and Open Whisper Systems announced that they had finished adding end-to-end encryption to “every form of communication” on WhatsApp, and that users could now verify each other’s keys.

In August of 1785, Blanchard became the first aeronaut to travel more than 200 kilometers in the air with a flight from Lille to Servon. As the balloon neared the French coast, it began to fall again, and the two men took off their coats and pants and threw them out, too, to lighten the load. In fact, about two-thirds of the way across the channel, the balloon began to leak. They launched the balloon from the seaside cliffs of Dover, England. On January 7, 1785, Blanchard crossed the English Channel by balloon with American doctor John Jeffries, who financed the voyage. He was the first vegas casino app balloonist, or aeronaut, to make ascensions in Germany, Belgium, Poland, Austria, and the Netherlands.

On May 9, 2014, the government of Iran announced that it had proposed to block the access to WhatsApp service to Iranian residents. In September 2017, security researchers reported to The New York Times that the WhatsApp service had been completely blocked in China. Another application called GB WhatsApp is considered malicious by cybersecurity firm Symantec because it usually performs some unauthorized operations on end-user devices. In April 2017, the perpetrator of the Stockholm truck attack reportedly used WhatsApp to exchange messages with an ISIS supporter shortly before and after the incident. Rudd publicly called for police and intelligence agencies to be given access to WhatsApp and other encrypted messaging services to prevent future terror attacks.

By early January 2015, WhatsApp had 700 million monthly users and over 30 billion messages every day. Days after the announcement, WhatsApp users experienced a loss of service, leading to anger across social media. Some time in 2013 WhatsApp acquired Santa Clara–based startup SkyMobius, the developers of Vtok, a video and voice calling app. To cover the cost of sending verification texts to users, WhatsApp was changed from a free service to a paid one.

According to the company, messages could be edited within a 15-minute window after being sent. In 2022, WhatsApp added the ability for users to turn off their online status. In August 2022, WhatsApp launched an integration with JioMart, available only to users in India. The Cloud API enables businesses to integrate WhatsApp with other software, have a central WhatsApp account for multiple users and implement advanced automation. In May 2022, WhatsApp launched its Cloud API services (now known as WhatsApp Business Platform) for larger businesses requiring features beyond the WhatsApp Business App.

The application can store encrypted copies of the chat messages onto the SD card, but chat messages are also stored unencrypted in the SQLite database file “msgstore.db”. The feature has to be turned on by the user and provides the option to encrypt the backup either with a password or a 64-digit encryption key. In February 2015, WhatsApp implemented voice calling, which helped WhatsApp to attract a different segment of the user population.
Touring Europe, Blanchard demonstrated his balloons and showcased the modern parachute, which he later used for a successful escape in 1793 when his hydrogen balloon ruptured. She died in Paris on July 16, 1819, falling out of her balloon to her death after fireworks set it on fire. His wife, Marie, continued ballooning and became Europe’s best-known female aeronaut. He fell more than 50 feet from the balloon and never recovered from his injuries. In 1808, Blanchard had a heart attack while on his 60th flight, over The Hague, in the Netherlands.

In a later update on November 30, WhatsApp added a Secret Code feature, which allows those who use locked chats to enter a unique password that hides those chats from view when unlocking the app. In March 2012, WhatsApp improved its location-sharing function, allowing users to share not only their location, but also the location of places, such as restaurants or hotels. Visual effects also became available, adding visual filters to a user’s video feed.
WhatsApp is owned by Meta, whose main social media service Facebook has been blocked in China since 2009. A message that promises to allow access to their WhatsApp friends’ conversations, or their contact lists, has become the most popular hit against anyone who uses the application in Brazil. In April 2017, nearly 300 WhatsApp groups with about 250 members each were reportedly being used to mobilize stone-pelters in Jammu and Kashmir to disrupt security forces’ operations at encounter sites. The messages involved discussing how to make an explosive device and a confession to the attack. In December 2015, it was reported that terrorist organization ISIS had been using WhatsApp to plot the November 2015 Paris attacks. In its revelation via documents received via court, the group claimed that the lawsuit brought against the company by WhatsApp threatened to infringe on its clients’ “national security and foreign policy concerns”.

Open Whisper Systems said that they had already incorporated the protocol into the latest WhatsApp client for Android, and that support for other clients, group/media messages, and key verification would be coming soon after. On November 18, 2014, Open Whisper Systems announced a partnership with WhatsApp to provide end-to-end encryption by incorporating the encryption protocol used in Signal into each WhatsApp client platform. When a user sends a message, it is stored on a WhatsApp server, which tries to forward it to the addressee, and repeatedly requests acknowledgement of receipt. WhatsApp’s voice codec is Opus, which uses the modified discrete cosine transform (MDCT) and linear predictive coding (LPC) audio compression algorithms. Some devices using dual SIMs may not be compatible with WhatsApp, though there are unofficial workarounds to install the app. Similarly to WhatsApp for web, Windows, Mac, and smartwatches, the iPad is a type of linked device that connects and syncs to WhatsApp running on a smartphone.
Researchers and journalists called on WhatsApp’s parent company, Facebook, to adopt measures similar to those adopted in India and restrict the spread of hoaxes and fake news. It was reported that US$3 million was spent in illegal concealed contributions related to this practice. After financial regulators in many regions raised concerns, Facebook stated that the currency, renamed Diem since December 2020, would require a government-issued ID for verification, and the wallet app would have fraud protection. This “Facebook coin” would reportedly be a stablecoin pegged to the value of a basket of different foreign currencies. The project reportedly involved more than 50 engineers under the direction of former PayPal president David A. Marcus. On February 28, 2019, The New York Times reported that Facebook was “hoping to succeed where Bitcoin failed” by developing an in-house cryptocurrency that would be incorporated into WhatsApp.
It became the world’s most popular messaging application in 2015, with 900 million users, and had more than 2 billion active users worldwide in February 2020. As of May 2025, the service had 3 billion monthly active users, making it the most used messenger app. WhatsApp has increasingly drawn its innovation from competing services, such as a Telegram-inspired web version and features for groups. In May 2025, Meta reported WhatsApp had over 3 billion monthly active users globally. On August 24, 2014, Koum announced on his Twitter account that WhatsApp had over 600 million active users worldwide. However, the company did not reveal the names of the end users, which according to research by Citizen Lab include, Saudi Arabia, Bahrain, Kazakhstan, Morocco, Mexico and the United Arab Emirates.
Sample data
In May 2019, WhatsApp was attacked by hackers who installed spyware on a number of victims’ smartphones. Higher usage was reported by frontline clinical staff to keep up with care needs, even though NHS trust policies do not permit their use. Further, the Cabinet Office had claimed that since many messages were not relevant to the inquiry, it only needed to hand over material it had selected as being relevant. A personal device of the former Prime Minister, Boris Johnson, had been compromised by a security breach, and it was claimed that it could not be switched on to recover messages. The researchers notified, Meta (who updated the enumeration problem in October), and deleted their copy of the phone numbers. In 2025, WhatsApp alerted 90 journalists and other members of civil society that they had been targeted by spyware used by the Israeli technology company Paragon Solutions.
He returned to the sky, likely for the first time in four years, in Rouen, France, that August, one of 15 more balloon ascensions he staged in his life. (Some sources suggest Blanchard flew in his balloon while in New York, but others disagree.) Blanchard moved into a “balloon house” to construct a new balloon, but tragedy struck. He got a better reception in Boston, sparking serious interest in ballooning. Ticket sales for his first flight and donations taken up outside the prison failed to raise the $1,500 in expenses he said the flight had cost.
In January 2018, WhatsApp released a standalone business app called WhatsApp Business which can communicate with the standard WhatsApp client. Privacy practices may vary, for example, based on the features you use or your age. The developer, WhatsApp Inc., indicated that the app’s privacy practices may include handling of data as described below. Tap Add member tag and type in your role to show people who you are or how you’re known in this group.These features will roll out over the coming weeks. Or record a voice message for those moments when just text isn’t good enough.Share daily moments through StatusShare your everyday life with those who matter.

On November 25, 2019, WhatsApp announced an investment of $250,000 through a partnership with Startup India to provide 500 startups with Facebook ad credits of $500 each. Both airlines had previously launched customer services on the Facebook Messenger platform. In September 2017, WhatsApp’s co-founder Brian Acton left the company to start a nonprofit group, later revealed as the Signal Foundation, which developed the WhatsApp competitor Signal. On May 18, 2017, the European Commission announced that it was fining Facebook €110 million for “providing misleading information about WhatsApp takeover” in 2014.
Previously the Android and Nokia Series 40 versions used an MD5-hashed, reversed-version of the phone’s IMEI as a password, while the iOS version used the phone’s Wi-Fi MAC address instead of the IMEI. WhatsApp uses a customized version of the open standard Extensible messaging and presence protocol (XMPP). The WebView2-based app has been criticised for its sluggish performance, high RAM usage, and requirement to keep the app running in the background to receive push notifications, compared to the previous native version. In 2023, WhatsApp replaced the Electron-based apps with native versions for their respective platforms. Similar to the WhatsApp Web format, the app, which synchronises with a user’s mobile device, is available for download on the website. Previously the WhatsApp user’s handset had to be connected to the Internet for the browser application to function but as of an update in October 2021 (and integrated by default in WhatsApp as of April 2022) that is no longer the case.
