LeaveHomeSafe (Chinese: 安心出行) is a digital contact tracing app launched by the Hong Kong Government on 16 November 2020 to conduct contact tracing in Hong Kong. It can be used as a companion of the Hong Kong Health Code system for registered users.[1][2][3]

The application can be downloaded for free, allowing users to record their whereabouts. Although it does not require GPS positioning, the user must authorize LeaveHomeSafe to use their mobile's communication network, camera lens and notification function and prevent it from going to sleep. It also captures other apps running on the phone, and the personal information collection statement of LeaveHomeSafe stated that the visit records submitted by the app to the Department of Health will be retained for seven years for confirmed COVID-19 cases only. The visit record, which by itself in isolation is not personal data, will be kept in users’ mobile phones for 31 days and will then be erased automatically.[4][5]

Privacy became the most controversial issue surrounding the app, prompting the use of fake LeaveHomeSafe apps which were later banned by the Government (with some were arrested for using them).

On May 3, 2022, FactWire reverse-engineered the Android version of "LeaveHomeSafe" and discovered that the program has a built-in face recognition module with features including the recognition of facial features and location, which led to another controversy about the privacy of the app.[6]

On January 8, 2023, the Hong Kong Government announced that the "LeaveHomeSafe" system would cease operation and no longer be updated. Users are still able to use other features such as the PCR Testing Registration Code.[7]

History

On 24 November 2020, Hong Kong's Chief Executive Carrie Lam said at a press conference that citizens will be encouraged to use it voluntarily, but it is not ruled out that citizens will be required to enter and exit designated premises (including restaurants, etc.). They must use the LeaveHomeSafe mobile app.[8] On the next day, the Hong Kong government stated that more than 12,000 public and private venues have been included in the list, including shopping centres, cinemas, government agencies, parks and restaurants, among which more than 1,000 restaurants of various types have participated.

The Office of the Government Chief Information Officer announced that as of 17 February 2021, LeaveHomeSafe had more than 1 million downloads.

Starting from 28 January 2021, the government stipulates that citizens entering government buildings or offices must scan the QR code on their mobiles with the LeaveHomeSafe app before they can enter.[9]

On 2 February, the Chinese Temples Committee stated that it is necessary to scan the QR code of LeaveHomeSafe to enter the Che Kung Temple in Sha Tin. The Wong Tai Sin Temple requires that from the first day of the Lunar New Year to the 15th of the first lunar month, believers who enter the temple must scan the LeaveHomeSafe QR code before they can get an "Entry Permit".[10]

On 10 February, the government announced that starting from 1 March, government employees and citizens must scan the QR code to record the name, contact number, and date and time of the visit when entering all government premises. On the 18th of the same month, the government required restaurants and other designated premises to force customers to use LeaveHomeSafe to record the whereabouts of citizens, otherwise they will be fined for 3 to 14 days.[11]

On 22 February, the number of downloads of LeaveHomeSafe exceeded 2.69 million. In addition to topping the download list in Hong Kong. However, in the App Store for Apple mobile phones, LeaveHomeSafe is only downloaded by registered users in 45 countries, and only Hong Kong and Macau rank first in downloads. Some netizens said that no one around them used LeaveHomeSafe, but the number of downloads increased sharply. In addition, there were comments that were not related to LeaveHomeSafe, such as game micro-transaction advertisements. Therefore, there's doubt that through the service company, the application finds people to download a large number of relevant programs and give them five-star praise, so as to raise the download ranking list of LeaveHomeSafe. Compared with Google Play, because the App Store has stricter controls on the "Ranking list", So it is more difficult to brush high downloads. The government Facebook page "Tamar Terrace" stated that the program can be used by people who live in Hong Kong or travel on business or travel. The government did not commission any person or organization to purchase any online advertisements, but it did not answer the number of repeated downloads of LeaveHomeSafe.[12][13]

On 2 August, the government released a new version of LeaveHomeSafe v2.1, which integrated privacy-preserving AI technology developed by a research team from Hong Kong Baptist University. The new AI technology enables automatic check-out when the user leaves a venue, resulting in more precise contact tracing. The team leader, Prof. Jianliang Xu, explained that it adopts a decentralized design and does not require network connectivity. He emphasized that the program's computations do not involve central servers and do not collect users' personal data or location information. This is in contrast to systems in Singapore, South Korea, and Mainland China that centrally collect user data.[14][15]

Starting from 1 November 2021, the government stipulates that citizens entering government buildings or offices must scan the "LeaveHomeSafe" QR code on their mobile phones before entering. Writing personal information is no longer allowed as an alternative.[16][17] The policy was extended to cover all premises starting from 9 December. The Government published the Technical Specifications, Security Risk Assessment and Audit Report and the Privacy Impact Assessment Report of the app a day later.[4]

On 22 May 2022, the government announced an official support hotline 18 months later of the app being launched.

The “LeaveHomeSafe” telephone hotline 2626 3066 will be launched tomorrow to handle public enquiries about installing or using the “LeaveHomeSafe” mobile app, from updates of the app to storing and display of the vaccine pass. LeaveHomeSafe hotline to start

The hotline will operate from 7am to 9pm daily. They can also seek assistance from staff at the OGCIO mobile support stations at 25 MTR stations on the use of "LeaveHomeSafe".

New functions of the app was announced on 27 January 2022, including displaying vaccination record.[18]

On 13 December 2022, the Government announced that the public would no longer have to scan the "LeaveHomeSafe" venue QR code upon entry of a premises to take effect on the 14th December 2022.[19] Furthermore, on the 28th December 2022, the Government announced that the vaccine pass would no longer have to be scanned upon entry of the required premises.[20]

Permissions

According to the permission statement of "LeaveHomeSafe" written on the Google Play, the permissions include using the camera, taking photos and videos, accessing device and application software records, capturing running application software, receiving internet data, controlling the vibration of the device, execute at startup, prevent the device from going to sleep, complete network access.[21]

According to the "Record App Activity" function at Apple IOS 15, this application will link to different websites to exchange data, including:

  • www.regqr.gov.hk
  • www.leavehomesafe.gov.hk
  • firebaselogging-pa.googleapis.com
  • device-provisioning.googleapis.com
  • firebaseinstallations.googleapis.com

Reactions

When LeaveHomeSafe was launched, it was questioned for requesting too many permissions, including "read USB content" and "check Wi-Fi connection." Afterwards, LeaveHomeSafe was updated, and the required permissions were reduced from 15 to 7. However, according to the version 1.1.4 of the application, the permission of the application still includes the retrieval of the running applications.

According to the program development forum, this is a tool that can help hackers invade. While the travel records that LeaveHomeSafe uploads to the government will be kept for 7 years, the records in the app will only be kept for 31 days. Johnny So, barrister and a member of the Progressive Lawyers Group, thinks that it is unacceptable and dangerous for the government to force citizens to use programs. It is believed that it will set a bad precedent, and people think that the government is invading personal privacy on the grounds of fighting the epidemic.

Some restaurants indicated that they would rather only do takeaways than having customers scan the QR code at the restaurant. They were worried about whether they could protect their privacy. Some hot pot restaurants pointed out that the related arrangements would not help the business too much. Some restaurants even post a QR code that mimics LeaveHomeSafe, but after scanning it with a mobile phone, it will link to an unrelated website.[22][11][23]

In February 2021, the Hospital Authority Employees Alliance questioned that LeaveHomeSafe is for monitoring the public, not for epidemic prevention. Subsequently, the Innovation and Technology Bureau and the Hospital Authority issued articles to refute the allegations. Patrick Nip, Civil Service Secretary, said that the LeaveHomeSafe program has no tracking function and will not reveal privacy. The Hospital Authority Employees Alliance issued a statement in response, saying that the Innovation and Technology Bureau misled the public and made it difficult for the public to feel at ease. It also criticized the government's poor performance in epidemic prevention and if the government continues to ignore public opinion, it will only further deepen public grievances. The organization stated that in the next week it will continue to appeal to citizens in different areas to boycott LeaveHomeSafe.[24]

Controversies

Download statistics questioned

Except for Hong Kong, Macao and China, downloads for the app "LeaveHomeSafe" ranks first in countries including Antigua and Barbuda, Bermuda, Bahamas, Belize, Cape Verde, Fiji, Micronesia, Guinea-Bissau, Iceland, Cayman Islands, Laos, Niger, Papua New Guinea, Solomon Islands, Turks and Caicos Islands as well as British Virgin Islands. Some countries mentioned above do not have a close relationship or frequent communications with Hong Kong, some netizens thinks that "someone" has asked for help from some company to increase downloads.[25]

Mandatory use

The Government stipulates that starting from 1 November 2021, people must scan the "LeaveHomeSafe" QR code when entering government venues, including hospitals and markets, and cannot use handwritten forms to write down personal information as an alternative. This is different from what the SAR government claimed at the beginning they will not force people using "LeaveHomeSafe" and is being criticized as backlash.[26]

Except for people under 12 and aged 65 or above, and people with disabilities who have difficulty in using "LeaveHomeSafe", all persons entering the following premises must use the "LeaveHomeSafe" app to scan the QR code on the spot after registering. It is forbidden to write down personal information on paper as a substitute. Since 29 April 2021, the mandatory scanning was extended to some restaurants, bathrooms, bars or pubs, party rooms, nightclubs etc. Starting from 9 December 2021, all restaurants and places of public entertainment required the scan.[27]

A community organization concerned about the issue of the homeless people stated that it is observed that less than a quarter of the homeless people in Hong Kong have their own smartphone, but the government has not stated whether the homeless people can be exempted and worried that the use of public facilities, such as the Social Welfare Department, sports centre and the Labor Department will be affected. They describe that "the government is setting a new poverty line".[28]

An injured man with a bloody head rushed to the accident and emergency department of Queen Elizabeth Hospital and being forced to scan the QR code of the "LeaveHomeSafe" before entering the accident and emergency department. However, citizens are already required to provide personal information when registering at the accident and emergency department, requesting emergency patients to use the "LeaveHomeSafe" being criticized as unnecessary, disturbing and annoying to the public.[29]

The Hong Kong government stated that starting from 1 November 2021, citizens entering the market are forced to use "LeaveHomeSafe". It is forbidden to write down personal information as substitute. Some people stated that they would not enter the market and would change to buy food from stalls outside the market or supermarkets. Some vendors said that some customers called to request diplomatic receipt of goods outside the market. Some vendors expected that the business would be reduced by 20 to 30%, thinking that the measures are unfair to them.[30] Chen Yuen-fai (陳袁輝), the chairman of Yau Ma Tei Market Tenants Association (油麻地街市枱商聯會), pointed out that there are difficulties in implementation. The current government market suffer the shortage of manpower, it is difficult to arrange people to check every entrance and exit. As a result, people can get into the market in some entrances and exits without checking their "LeaveHomeSafe". It is estimated that the entire Hong Kong needs 2,000 security guards to fulfill the needs. He also worries that people will reduce entering to the government market, preferring to patronize to the street vendors, criticizing the measures causing fewer business to the merchants.[31]

Fake apps

On 1 November 2021, the police has arrested five people in Immigration Tower for using an imitation app. Three of these were government employees and the other two were contractors.[32] More were arrested later for using it in the restaurant.
