We know subscriptions can be annoying, and have tried to make it easy to cancel your account. Just go to Account >> Plan & Usage and then select "Change Plans" and either the "free" plan if you would like to keep access to your data, but not be charged, or "permanently delete your account," if you would like all your data and billing info wiped from our servers.
Option 1: Switch to Free
First step is to go to your account in the top right corner, rollover, and then click Plans & Usage:
On the next screen, look at the bottom of the screen below all the paid plan, and click switch to free plan.
Option 2: Permanently Delete Your Account
You can also click "permanently delete your account," right from the main page, as shown below:
Your card will no longer be charged (see below). The change will be effective immediately, but does not work retroactively. For example, if you realize you were just charged for a month, and cancel a few days later, your credit card will never be charged again, but you will not get a refund for that last month. You will always have access to your data without paying a dime, but you do have to remove any ethnio code from your servers, or you'll hear from us, rather quickly. And you won't be able to pay incentives using Ethnio without an active paid account. If you want to completely delete your account, like how we wish Facebook would allow us to delete an account, then simply drop us an email saying you would like your account completely deleted. That would be permanent deletion — wiped from all backups and never to be seen again.
