Removing an add-on from your account can have major effects on your data and account depending on how much they've been used prior to removal.

If you remove an add-on during a trial period, this will take effect immediately.

If an add-on that is being paid for is removed, it will actually be removed at the end of the existing billing cycle.

Once an add-on has been removed, expect to have data completed removed if the data was reliant on that add-on. You also may lose access to certain areas where the data was being stored.

Before removing an add-on, double check to ensure you've moved data around so that it won't be deleted (if you want to keep the information) and be prepared to lose access to certain connected data.
