The information we collect depends on the context of your interactions with Butterfly and the choices you make (including your privacy settings), the products and features you use, your location and applicable law.

(A) Services 

In general, our Services are intended for use by Service Users. As a result, for much of the personal information (including patient personal information) we collect and process through the Services, we act as a data processor. This means, it is primarily our Service Users that control what personal information we collect through the Services and how we use it. Therefore, if you are a patient of one of our Service Users, and have privacy related questions or concerns about the privacy practices of or the choices the relevant Service User has made to share your information with us or any other third party, you should contact the relevant Service User or review their or (where applicable) their organizations' privacy notices. 

Butterfly is not responsible for the privacy or security practices of its Service Users, which may differ from those set out in this Notice.

Information you provide to us: 

If you are a Service User you (or your team administrator) may provide certain personal information to us through the Services - for example, when you sign up for a Butterfly account to access and use the Services, when you consult with customer support or send us an email or communicate with us in any way (for example, to make a support request).

The personal information we collect may include: 

  • Business contact information (such as your name, job title, organization, phone number, email address and country);

  • Payment information (including your credit card numbers and associated identifiers, billing address and background information, but only where you pay for the Services).

If you ever communicate directly with us, we will maintain a record of those communications and responses. 

Information we collect automatically:

When you use or interact with the Services, we automatically collect or receive certain information through our Services (for example in log files) and through other technologies (such as cookies) about your device and usage of the Services. In some (but not all) countries, including countries in the European Economic Area ("EEA"), UK and Switzerland, this information is considered 'personal data' under data protection laws. For further information please review the section "Cookies and Similar Technologies" below. 

The information we collect includes: 

  • Log and usage data, which is service-related, diagnostic, usage and performance information our servers automatically collect when you access or use our Services and which we record in log files. This log data may include the Internet Protocol (IP) address, device information, browser type and settings and information about your activity in the Services (such as the date/ time stamps associated with your usage, pages and files viewed, searches and other actions you take (for example, which features of you use)), device event information (such as system activity, error reports (sometimes called 'crash dumps') and hardware settings). 
  • Device data, such information about your computer, phone, tablet or other device you use to access the Services. This device data may include information such as your IP address (or proxy server), device and application identification numbers, location, browser type,  hardware model Internet service provider and/or mobile carrier, operating system and system configuration information. If you are using our mobile App, we may also collect information about the phone network associated with your mobile device, your mobile device’s operating system or platform, the type of mobile device you use, your mobile device’s unique device ID and information about the features of our mobile App you accessed.
  • Location data, such as information about your device's location, which can be either precise or imprecise. How much of this information we collect depends on the type and settings of the device you use to access the Services.  For example, we may use GPS and other technologies to collect geolocation data that tells us your current location (based on your IP address).  You can opt out of allowing us to collect this information either by refusing access to the information or by disabling your Location setting on your device. Note however, if you choose to opt out, you may not be able to use certain aspects of the Services.

This information is used to: 

  • maintain the security of the Services;
  • provide necessary functionality;
  • improve performance of the Services;
  • assess and improve Service User's experience of the Services;
  • review compliance with applicable usage terms;
  • identify future opportunities for development of the Services;
  • assess capacity requirements;
  • identify customer opportunities and for the security of Butterfly generally (in addition to the security of our Services); and
  • analyze overall trends, to help us provide and improve our Services, and to guarantee their security and proper functioning.

Some of the data automatically collected within the Services, whether alone or in conjunction with other data, could be personally identifying to you. Please note that this data is primarily used for the purposes of identifying the uniqueness of Service User logging on (as opposed to specific individuals), apart from where it is strictly required to identify an individual for security purposes or as required as part of our provision of the Services to our customers (where we act as a data processor). 

Information we process about our Service Users' patients:  We process certain personal information about our Service Users patients on behalf of our Service Users (where we act as a data processor).  This personal information includes: 

  • Identification and contact data (name, title, date of birth, sex, medical record number (MRN), accession number). 
  • Patient health information ("PHI"), such as MRN data, study description and related metadata (such as comment data from Service Users about an ultrasound study) and  other categories of PHI uploaded by (or on behalf of) the Service Users  in connection with the Services. 

As described above, in most cases, we only process patient personal information on behalf of and as instructed by our Service Users (the data controllers of the personal information).  

However, where permitted by the relevant Service User and applicable law, we may leverage certain patient data collected through the operation of the Services for our internal research and development purposes to develop and improve our Services (for which we will be a data controller).  For these purposes, we only use patient personal information in a de-identified form that does not specifically identify any particular patient (for example, by reference to their name or other identification data).  For example, we may leverage de-identified patient data to train our models and algorithms to better interpret the ultrasound images captured from Butterfly devices, to make more consistent measurements and therefore to improve the functionality of our Services and diagnostic outcomes. To the extent the de-identified patient data is considered personal information under applicable privacy and data protection law, we will ensure that such data is processed in compliance with such privacy and data protection laws (including seeking patient consent where legally required). Please review our Patient Privacy Notice for further information.
