The Mendota Wind Watch app stores the following data about you / your device:
Your data is not shared with any third parties and the database is secured such that only your device (via Auth ID) can access your stored data (alert sensitivity settings; FCM token). The creator of the app also is able to access this information in the database console.
This information uniquely identifies your device, but it does not identify you by name. It is used to ensure your device gets notified when your alert is triggered and is immediately removed from the database when your device is sent a notification.
By default, all alarm data in the database is removed at 8:00pm CST each night. If one choses to make an alarm permanent, that data will be stored as such. However, this data can still be removed if the user chooses to disable the permanent alarm.
