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.
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
We collect information to provide better services to all of our users.
We collect information in two ways:
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.
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:
We may collect device-specific information (such as your hardware model, operating system version, unique device identifiers, and mobile network information including phone number).
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:
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.
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 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.
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 will share personal information with companies, organizations or individuals outside of Health Visuals when we have your consent to do so. We require opt-in consent for the sharing of any sensitive personal information.
If your Crowdsav Account is managed for you by a corporate / organisation administrator (for example, for employees ) then your corporate / organisation administrator will have access to your Crowdsav Account information (including your email and other data). Your domain administrator may be able to:
Please contact your corporate / organisation administrator's for more information.
We will share personal information with companies, organizations or individuals outside of Health Visuals if we have a good-faith belief that access, use, preservation or disclosure of the information is reasonably necessary to:
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.
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:
This is information which you provide to us which personally identifies you, such as your name, email address or billing information, or other data which can be reasonably linked to such information by Health Visuals.
You may access some of our services by signing up for a Crowdsav Account and providing us with some personal information (typically your name, email address and a password). This account information will be used to authenticate you when you access Crowdsav services and protect your account from unauthorized access by others. You can edit or terminate your account at any time through your Crowdsav Account settings.
A cookie is a small file containing a string of characters that is sent to your computer when you visit a website. When you visit the website again, the cookie allows that site to recognize your browser. Cookies may store user preferences and other information. You can reset your browser to refuse all cookies or to indicate when a cookie is being sent. However, some website features or services may not function properly without cookies.
An anonymous identifier is a random string of characters that is used for the same purposes as a cookie on platforms, including certain mobile devices, where cookie technology is not available.
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.
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.
Like most websites, our servers automatically record the page requests made when you visit our sites. These “server logs” typically include your web request, Internet Protocol address, browser type, browser language, the date and time of your request and one or more cookies that may uniquely identify your browser.
Here is an example of a typical log entry where the search is for “cars”, followed by a breakdown of its parts:

22.214.171.124is the Internet Protocol address assigned to the user by the user's ISP; depending on the user's service, a different address may be assigned to the user by their service provider each time they connect to the Internet;
25/Mar/2003 10:15:32is the date and time of the query;
Firefox 1.0.7; Windows NT 5.1is the browser and operating system being used; and
740674ce2123a969is the unique cookie ID assigned to this particular computer the first time it visited Crowdsav. (Cookies can be deleted by users. If the user has deleted the cookie from the computer since the last time s/he visited Health Visuals, then it will be the unique cookie ID assigned to the user the next time s/he visits Crowdsav from that particular computer).
This is a particular category of personal information relating to confidential medical facts, racial or ethnic origins, political or religious beliefs or sexuality.
This is information that is recorded about users so that it no longer reflects or references an individually identifiable user.
