CancerBuddy Privacy Policy

Your privacy comes first

The Bone Marrow & Cancer Foundation has created CancerBuddy as a welcoming, safe, empowering resource for patients, caregivers and survivors. This means:


You decide what personal information to share.

  • Personal information is requested to access and optimize App features. Opt-outs are provided, so that users can decide what information they choose to share and delete their data entirely.

Only your first name will be seen by the community.

  • Safeguards are built into the App to help protect personal information and younger App users. Community Guidelines established in the Terms of Use reinforce respectful conduct by all.

 Information will be shared with select outside parties.

  • Information/data sharing is limited to CancerBuddy and BMCF service providers, partners and sponsors, as outlined in our policy.

Changes to this Policy can be reviewed anytime.

  • This helps ensure informed consent – and your questions are always welcome.

4. Policy Changes

The Bone Marrow and Cancer Foundation, Inc. (hereinafter, “BMCF,” or “we” or “our”) owns and operates the Cancer Buddy mobile application (the “App”).  This Privacy Policy (the “Policy”) is intended to provide you with information regarding our policies, practices and procedures as they relate to information we collect through the App, including the types of personal information we collect on the App, how we may use that information and with whom we may share it. Please note that this Policy applies only to our information-gathering, processing and sharing practices through the App, and therefore it does not apply to any of the information (and related practices) that we may collect via other means, methods or channels – such as offline, the BMCF website, or any other means.

1. Information we collect

What personal information does the App collect, and how is it used?

You can download the App to your mobile device without having to provide us with any personally identifying information.  However, if you want to utilize any of the functionality of the App, you will need to register and then login to your account. If you register and create an account, you will be asked to provide some personally identifiable information, including your name and email address. You will also be asked to provide a user name – please note that your user name will be publicly displayed when you use the App, so please don’t choose a user name that can identify you if you do not wish to be identified.  In regard to the information that we collect when you register, we sometimes use this information to communicate with you, or as further described in this Policy. 

How is non-personally identifiable information/data collected and used?

The App may collect certain non-personally identifiable information automatically from your use of the App and its functions in order to allow us to monitor and improve the user experience and diagnose issues. We may collect this information ourselves, or through third-party analytic services such as Google Analytics.  A representative, non-exhaustive list of the types of non-personally identifiable information collected may include: the mobile network you’re using, your internet protocol address, operating system, screen size and other default system operations. 

Additionally, we may use such technologies like cookies (small files stored by your mobile web browser or “webview”), beacons, or unique device identifiers to identify your mobile device, and  collect information on your online activities. We may use this information internally to help us provide you with a more personalized user experience.

We also track usage events in the App, and if you register then we may tie that usage with personally identifiable information (e.g., whether and to whom you may have shared your activities with); usage may also be linked to a particular mobile operating system, app version, and mobile device.  We do not resell or redistribute this information for commercial gain, and all of this information is stored in your account in a database that is hosted by BMCF.  

How can you opt out?

You can manually delete any information in your account at any time, and you can also stop us from collecting information via the App by uninstalling, deleting or otherwise removing the App from your mobile device. We will retain any user-provided data for as long as you use the App and for a reasonable time thereafter. Please note that some your user-provided information may be required in order for the App to function properly, or we may be required to retain certain information pursuant to applicable law or regulation.

If you would like to request that we delete the personally identifiable information that you have provided to us via the App, please contact us at This email address is being protected from spambots. You need JavaScript enabled to view it. and we will endeavor to respond to any commercially reasonable requests within a reasonable timeframe.

Does the App track your location?

No, this App does not collect precise real-time location information of your mobile device. 

2. Safeguards

How does the App help keep data secure?

Your privacy is important to us, and we have put in place security systems designed to prevent unauthorized disclosure and use of your private information.  In the case of any third-party providers, we have asked for similar assurances. The security systems in place are structured to deter and prevent hackers and others from accessing your information. Due to the nature of Internet communications and evolving technologies, however, we cannot provide, and disclaim, assurance that such information and communications will remain free from loss, misuse, or alteration by human error or third parties who, despite our security measures efforts, may obtain unauthorized access. 

How are younger App users protected?

The App is intended for users aged 13 and up, and we do not knowingly or intentionally solicit data from or market to children under the age of 13. As specified in the Terms of Use, individuals who are less than 13 years of age are only permitted to use the App with parental/guardian consent and supervision. If you are a parent or guardian and become aware that your child has provided us information without your consent, please contact us at This email address is being protected from spambots. You need JavaScript enabled to view it. to request that we delete such information.  We will delete such information from our files within a reasonable amount of time from your request.

3. Information & data sharing

Instances in which we may share information with third parties

We may disclose all of the information (described herein) that we collect, as stated in this Policy, including in accordance with the terms set forth in this section.

Additionally, we may disclose both personally and non-personally identifiable information as follows:

  • as required by law, such as to comply with a subpoena or similar legal process;
  • when we believe in good faith that disclosure is necessary to protect BMCF’s rights, protect your safety or the safety of others, investigate fraud, or to respond to a government request;
  • with service providers who work on behalf of BMCF, such as the BMCF application developers and technical team. These service providers will be given access to such information only for the purposes related to the App, and will be asked to adhere to the rules set forth in this Policy;
  • if we are involved in any type of organizational change, in which case you will be notified via email or prominent notice of any change of ownership, and you will also be informed of any choices you may have regarding the use of your information at that time.

Sponsor interactions

The App may present sponsored content and certain community features may be sponsored by third parties. Links from sponsored content may lead to third-party websites, which are subject to separate privacy policies and terms of use.
