You are purchasing a service plan based on WaterWatch PRO features. Each plan lets you define locations in multiples of 3, 4 or 5 for the Bronze, Silver and Gold levels, respectively.
For example, if you need 10 locations at the Silver level, multiply the package price by 3, which lets you define up to 12 locations in total. Your monthly payment will be $54 (3 packages x $18/month).
WaterWatch PRO begins monitoring your defined location when you create your paid account. If you began a free trial and upgraded, monitoring for your trial location continues, along with new locations you add. You will be charged each month for the entire month, regardless of the day in the month monitoring began.
Anytime before your FREE trial expires, you may choose to upgrade to one of WaterWatch PRO's Premium Services.
From within the app, go to Settings from the Main Menu. Then select Upgrade. You will be sent a link where you can select the desired upgrade service level.
You may choose to move between service levels at any time. Within the app, choose Settings from the Main Menu. Then select Account, where you will see your current level and options to choose either of the others.
If you change service levels within a month, your billing for the next month will be at the new level. For example, if you begin with Silver and halfway through the month, decide to upgrade to Gold, you will be billed at the Gold level beginning with the billing cycle for the next month.
