This App is made available to you by the Pfizer company identified below.  The App ZeckTag is a service to avoid tick bites.


“Personal Data” is data that identifies you as an individual or relates to an identifiable individual. The Personal Data processed through this App consists of (necessary data marked ( *)):

  •  User’s name
  • Location of the tick bite
  • Date and time of the tick bite
  • Photos taken by user (for ex.: photo of the tick bite)

The App will indicate, such as through an asterisk, which Personal Data is required for the App to function.  If you do not provide such data, we will not be able to provide you with the App’s features. 


We do not receive any Personal Data that you enter into the app.  The data is stored within the App on your mobile device and will remain under your own control and responsibility.

You may choose to share reports or other messages generated by the App with others.  If you do, the report will be sent to the person(s) you designate using other functionality on your device.


We may use tracking technologies to recognize you as you use or return to the App so that we can understand how the App is used, optimize user engagement with the App and customize and enhance your experience.  These technologies collect certain data automatically, such as: 

  • Data about your device, such as your screen resolution, operating system, device manufacturer and model, and language. We use this data to ensure that the App functions properly. 
  • Data about your use of the App, including content viewed, features used and the dates and times of your interactions with the App. We use this data to understand how users engage with the App and to customize and improve the App experience.

We use third-party services that use cookies and/or similar technologies to collect and analyse data about App use and to report on activities and trends to improve user experience.  Such services may also collect data regarding the use of other websites, apps and online services. To learn more about how this information is used and to limit and/or modify the use of such information, please go to respectively.


Your Personal Data is stored on your device.  It is not transmitted to us.  If you lose your device, you will also lose the Personal Data stored on it, and the data may be vulnerable to exposure, especially if you have not enabled secure access for your device (such as through a password or fingerprint authentication).  In addition, if you choose to share reports or other messages generated by the App with others electronically, you are advised to first check the security features of your email or other applicable communications features on your device, as they do not operate within the App.

For your convenience, the App may give you the opportunity to back up the Personal Data stored on the App with a third-party storage provider.  Pfizer has no responsibility for any data that you choose to share with that provider.  


You may stop all collection of Personal Data by the App by uninstalling the App.  You may stop the receipt of push notifications through your device settings.

We will retain the data we collect from your use of the App for as long as needed or permitted in light of the purpose(s) for which it was obtained and as outlined in this Privacy Notice.  The criteria used to determine our retention periods include:  (i) the length of time we have an ongoing relationship with you and provide the App to you; (ii) whether there is a legal obligation to which we are subject; or (iii) whether retention is advisable in light of our legal position (such as in regard to the enforcement of the App Terms of Use, applicable statutes of limitations, litigation or regulatory investigations).


The data we collect through the App may be stored and processed in any country where we have facilities or in which we engage service providers, including in the United States and where our affiliates operate.

This Privacy Notice does not address, and we are not responsible for, the data collection, use, disclosure or security practices, or other practices, of any third party, including any third party operating a service to which the App links.  The inclusion of a link within the App does not imply our endorsement of the linked service.
