Our Testing Platform:

The Testing Platform will ask permission to access your mobile device camera to enable you to scan the QR code on your COVID-19 test cartridge or package. If you do not enable this permission, you will not be able to use the test platform. The Testing Platform only uses this permission while activating your test to obtain test cartridge information by reading the QR code if you choose to do so. The Testing Platform does not access any photos stored on your device and does not write to your device’s photo storage. Users who grant this permission can disable it at any time through their device’s app settings, but may not start the test if not enabled while performing a CLEO™ ONE test.


2. Ask permission to access GPS and to use location information

If required, we may collect information in connection with our governmental reporting obligations (which also includes de-identified demographic information) and zip code-level regions (or unidentified geographic units) of test results for public health reporting.

The Test Platform may ask permission to use the location information or GPS information of the user's mobile device to get the user's consent.


3. Ask permission to use Bluetooth

The Testing Platform will ask permission to use the mobile device Bluetooth to operate the CLEO ONE device and perform the Test. While the test is being performed, the mobile device uses Bluetooth to connect with the CLEO ONE device. The App may check the Test process steps of the CLEO ONE device and obtain the test results by Bluetooth pairing communication with the device.


4. Ask permission to access storage 

The App may collect the test taker's name, date of birth, gender, and location information provided by the mobile device, the serial number of the test device, lot information and expiration date of the test cartridge, and the date and time when the test was performed.

To write, read, and store test results transmitted from the test device, the App may ask permission to access the storage of the mobile device.

If the user deletes the App, the user may permanently lose the previous test results stored in the app storage.
