Your location information is used to optimize features of the Quell Services.  Certain entries in the Quell Health Cloud are geostamped so that we can provide better data analytics. In no case is your physical location shared with third parties.

Do the Quell Services Use Cookies?

Our website will send a “cookie,” a small text file, to your computer. This allows us to recognize your computer the next time you visit. Also, if you create a shopping cart, and leave without checking out, a cookie will allow us to remember what you were shopping for and keep it in the cart for you. If you do not wish to accept cookies, refer to the “help” file of your internet browser to learn how to block all cookies or receive a warning before a cookie is stored.

NeuroMetrix works with an analytics partner to improve the quality of the Quell services, the websites, and to give you access to more relevant advertising. Our analytics partner may install “persistent cookies” on your computer or mobile device to perform these services when you first visit our website. A persistent cookie remains in your browser after you have left the Quell services website. This allows our analytics partner to track your activity on the Quell services website, and on other sites you visit. If you visit our website, we collect and store some “visitor information” from you. This information may include the name of the domain and host from which you access the internet, the internet protocol (IP) address of the computer you are using, the date and time you visit our website, and the internet address of the website from which linked you to our website. We use this information to measure the traffic on our website. We use this information to make our website more useful to you. We delete this information after some time.

Can Children Use the Quell Services?

The Quell Services are not meant for use by children under 18, and children under the age of 18 are not permitted to create Quell Health Cloud Accounts. If you are the parent of a child under 18 and believe he or she has created a Quell Health Cloud Account, please contact NeuroMetrix at 1000 Winter street, Waltham, Ma, 02451 so the account can be deleted, and your child’s information can be removed from our active systems.

Do the Quell Services Track My Activity Across Websites?

NeuroMetrix may track your activity across multiple websites. When you visit the websites, we automatically collect the name of the website you visited from (called the “referring page”) and the name of the website you chose to visit immediately after ours (called the “exit page”), and information about other websites you have recently visited. This information is used to improve our websites. The Quell Services do not honor the “do not track” settings available on most browsers. When Quell’s website detects the do not track signal from your browser, it will still collect referring and exit page information and other information when you visit our website.

What if I Follow a Link to a Third Party Website?

The websites may include links to other websites.  The fact that we link to a website is not an endorsement, authorization or representation of any affiliation with that third party.  NeuroMetrix does not exercise control over third party websites.  These other websites may place their own cookies or other files on your computer, collect data or solicit personal information from you.  Other sites may follow different rules regarding the use or disclosure of Personal Information that you submit to them.  We encourage you to read the privacy policies and terms of use of such other websites.  Please be aware that our Privacy Policy does not apply to these other third party websites.

Can I Delete My Quell Services Accounts?

Customers can request that their Quell Health Cloud Account be deleted by contacting customer care at 1-800-204-6577. NeuroMetrix is unable to delete any de-identified data created from your Quell Health Cloud Account because NeuroMetrix will be unable to determine which de-identified data was created from your information.  Accordingly, NeuroMetrix may continue to use de-identified data after you delete your account.

Will I Receive Marketing Messages if I Use the Quell Services?

From time to time, NeuroMetrix may use your email address to send promotional messages to you regarding products or services that may be of interest.  You can opt out of receiving promotional emails from NeuroMetrix by hitting the “unsubscribe” link in any email, or by emailing NeuroMetrix at Opting out of promotional emails will not end transmission of important service related emails related to the ongoing use of the Quell services. You may also receive push notifications through the mobile app.  You  may need to activate or opt-in to push notifications, depending on your device, and you can also opt out or turn push notifications off.

Will NeuroMetrix Share My Information?

We may transmit your Personal Information to select business partners for the purpose of providing you information or services which you requested.  In such cases, we require our business partners to adhere to privacy policies comparable to NeuroMetrix’ privacy policies and in all cases, consistent with applicable law.

How Does NeuroMetrix Protect My Information?

NeuroMetrix takes reasonable precautions to protect its information systems from damage or tampering. These include but are not limited to physical, administrative, and technical safeguards. Despite our best efforts, NeuroMetrix cannot promise or guarantee that hackers, cyber-criminals, or others will not be able to access, steal, or modify the information you share with us.

What if I Live in California?

California Civil Code Section 1798.83 permits visitors to the websites who are California residents and who have provided us with “personal information” as that term is defined in Section 1798.83, to request certain information about the disclosure of that information to third parties for their direct marketing purposes.  If you are a California resident, you may contact us in writing at NeuroMetrix, 1000 Winter Street, Waltham, Ma, 02451.

What if I Live Outside of the United States?

You should be aware that the United States and other countries have not harmonized their privacy regulations.  Because NeuroMetrix and its servers are located in the United States and because the Quell Services are directed towards the United States market, our Privacy Policy has been prepared to comply with applicable United States law.  By accessing and/or using the websites or the Quell Services, and providing Personal Information to us, you agree to the level of privacy protection set forth in this Privacy Policy.
