The sunZapp Sun Protection App - User Agreement


The sunZapp app is a tool to help you enjoy your time in the sun. It was designed by Klein Buendel, Inc. under a contract with the National Cancer Institute (NCI).

If you accept all of the information in this disclaimer, please continue using sunZapp. If you do not agree, do not use this app.

sunZapp is not a medical device. It should not be used to replace the advice of your health care provider. Use sunZapp to help reduce UV exposure and avoid skin damage.  And examine your skin at least once each year. Look for spots and moles that have changed in size, color or texture. If you notice anything, tell your health care provider.

sunZapp provides feedback by estimating the amount of UV at the cell phone’s location. It combines the UV level with information you provide about yourself and your environment.

The app calculates the amount of UV based on forecast UV Index available from the National Oceanic and Atmospheric Administration (NOAA). The forecasts are available in 1-hour intervals for 0.5° square latitude/longitude units over 5 days. The location of the cell phone is obtained from GPS software in the cell phone or from information that you provide.

All UV Index forecasts have inaccuracies because they are predictions. sunZapp does not measure the actual amount of UV. The forecast UV Index can overestimate or underestimate the amount of actual UV that occurs.

The calculations and formulae in the sunZapp app are based on information provided by a variety of sources. In some cases, these data are incomplete. The calculations and formulae cannot be exact. Also, data may change in real time as the UV Index forecast changes or you provide new or more information to the sunZapp app.

Klein Buendel, Inc., the NCI and NOAA cannot be held responsible for any consequence that may result from the use of the sunZapp app.
