The pricing plans are available here: https://cluelabs.com/pricing

You will see Location under each plan. This is how many times you can look up a user's location in a month. One use event occurs each time you use a trigger in Articulate Storyline (or an action in Adobe Captivate) to look up the learner's location. For example, in a scenario where your course checks the learner's location when it first opens, and 5 learners open your course: you will use 5 credits.

You can track your current usage and your remaining credits on this page: https://cluelabs.com/account/usage

There is a default email notification that goes out when you exhaust 80% of the credits for the month, so this will give you enough time to make arrangements if needed. You can choose to upgrade to the next plan if you’d like to keep using location in your courses or do nothing. If you run out of credits, you will not be able to look up locations for the remainder of the billing period, and the credits will reset with the next billing cycle. You can verify that the notification is turned on (or turn it off if needed) on the Account page.
