Our services are based on the crowdsourcing concept. The feedback you receive when using the various CPR modes is based on data that others before you have collected during their training by certified CPR instructors. The collection of gender, body weight and height data to calculate the body-mass index (BMI) is to customise the data for you based on someone of the same gender trained before you who has the same BMI. Therefore collection of these data is to assist others after you to perform better CPR. The locations of automated external defibrillators (AEDs) are provided by members of the public just like you who value the access to these devices. Just like others before you, the information of these devices provided by you will assists others after you in their times of distress. We hope that the details of these AED locations will be clear and concise, so that others after you will be able to find them in the shortest time possible.

As you use our services, we want you to be clear how we're using information and the ways in which you can protect your privacy.

Our Privacy Policy explains:

  1. What information we collect and why we collect it.
  2. How we use that information.
  3. The choices we offer, including how to access and update information.

We've tried to keep it as simple as possible, but if you're not familiar with terms like cookies, IP addresses, GPS coordinates and browsers, then read about these key terms below first. Your privacy matters to Health Visuals (owner of Crowdsav) so whether you are new to Crowdsav or a long-time user, please do take the time to get to know our practices – and if you have any questions contact us at admin[at]healthvisuals[dot]com.

We collect information to provide better services to all of our users.

We collect information in two ways:

  1. Information you give us. For example, many of our services require you to sign up for a Crowdsav Account. When you do, we'll ask for personal information, like your name, email address, gender, height and weight, or credit card.

  2. Information we get from your use of our services. We may collect information about the services that you use and how you use them. This information includes:

    • Device information
      We may collect device-specific information (such as your hardware model, operating system version, unique device identifiers, and mobile network information including phone number).

    • Log information
      When you use our services or view content provided by Health Visuals, we may automatically collect and store certain information in server logs. This may include:

      1. details of how you used our service
      2. internet protocol (IP) address
      3. cookies that may uniquely identify your browser or your Crowdsav Account.

    • Location information
      When you use a location-enabled Crowdsav service, we may collect and process information about your actual location, like GPS signals sent by a mobile device. We may also use various technologies to determine location, such as sensor data from your device that may, for example, provide information on nearby Wi-Fi access points and cell towers.

    • Unique application numbers
      Certain services include a unique application number. This number and information about your installation (for example, the operating system type and application version number) may be sent to Health Visuals when you install or uninstall that service or when that service periodically contacts our servers, such as for automatic updates.

    • Local storage
      We may collect and store information (including personal information) locally on your device using mechanisms such as browser web storage (including HTML 5) and application data caches.

    • Cookies and anonymous identifiers
      We use various technologies to collect and store information when you visit Crowdsav, and this may include sending one or more cookies or anonymous identifier to your device. We also use cookies and anonymous identifiers when you interact with services we offer to our partners.

We use the information we collect from all of our services to provide, maintain, protect and improve them, to develop new ones, and to protect Health Visuals and Crowdsav users. We also use this information to offer you tailored content – like giving you more relevant CPR feedback and AED locations.

We may replace past names associated with your Crowdsav Account so that you are represented consistently across all our services. If other users already have your email, or other information that identifies you, we may show them your publicly visible Crowdsav Profile information, such as your name.

When you contact Health Visuals, we may keep a record of your communication to help solve any issues you might be facing. We may use your email address to inform you about our services, such as letting you know about upcoming changes or improvements.

We use information collected from cookies and other technologies to improve your user experience and the overall quality of our services.

We will ask for your consent before using information for a purpose other than those that are set out in this Privacy Policy.

Health Visuals may process your personal information on a server located outside the country where you live.

People have different privacy concerns. Our goal is to be clear about what information we collect, so that you can make meaningful choices about how it is used. For example, you can:

You may also set your browser to block all cookies, including cookies associated with our services, or to indicate when a cookie is being set by us. However, it's important to remember that our services may not function properly if your cookies are disabled

Our services provide you with different options on sharing and removing your content.

Whenever you use our services, we aim to provide you with access to your personal information. If that information is wrong, we strive to give you ways to update it quickly or to delete it – unless we have to keep that information for legitimate business or legal purposes. When updating your personal information, we may ask you to verify your identity before we can act on your request.

We may reject requests that are unreasonably repetitive, require disproportionate technical effort (for example, developing a new system or fundamentally changing an existing practice), risk the privacy of others, or would be extremely impractical (for instance, requests concerning information residing on backup tapes).

Where we can provide information access and correction, we will do so for free, except where it would require a disproportionate effort. We aim to maintain our services in a manner that protects information from accidental or malicious destruction. Because of this, after you delete information from our services, we may not immediately delete residual copies from our active servers and may not remove information from our backup systems.

We do not share personal information with companies, organizations and individuals outside of Health Visuals unless one of the following circumstances apply:

We may share aggregated, non-personally identifiable information publicly and with our partners – like researchers, emergency service providers. For example, we may share information publicly to show trends about the general use of our services.

If Health Visuals is involved in a merger, acquisition or asset sale, we will continue to ensure the confidentiality of any personal information and give affected users notice before personal information is transferred or becomes subject to a different privacy policy.

We work hard to protect Health Visuals and our Crowdsav users from unauthorized access to or unauthorized alteration, disclosure or destruction of information we hold. In particular:

Our Privacy Policy applies to all of the services offered by Health Visuals Pte Ltd and its affiliates, excludes services that have separate privacy policies that do not incorporate this Privacy Policy.

Our Privacy Policy does not apply to services offered by other companies, organisations or individuals, or other sites linked from our services. Our Privacy Policy does not cover the information practices of other companies and organizations who advertise our services, and who may use cookies, pixel tags and other technologies.

We regularly review our compliance with our Privacy Policy. When we receive formal written complaints, we will contact the person who made the complaint to follow up. We will work with the appropriate regulatory authorities, including local data protection authorities, to resolve any complaints regarding the transfer of personal data that we cannot resolve with our users directly.

Our Privacy Policy may change from time to time. We will not reduce your rights under this Privacy Policy without your explicit consent. We will post any privacy policy changes on this page and, if the changes are significant, we will provide a more prominent notice (including, for certain services, email notification of privacy policy changes).

IP address

Every computer connected to the Internet is assigned a unique number known as an Internet protocol (IP) address. Since these numbers are usually assigned in country-based blocks, an IP address can often be used to identify the country from which a computer is connecting to the Internet.

GPS coordinates

These include the Langtitude and Longtitude data submitted by your mobile devices fitted with the necessary hardware. The data will be able to pinpoint your location on a map at a specific point in time and place only when the feature of the Crowdsav platform requires to perform its task.
