The €9 base covers the included amounts. Above them, each item is billed in blocks on its highest count during the month. For example, if you run 60 monitors for two days and 20 for the rest of the month, that month includes 2 extra blocks of 25 monitors: €8. Removing things before the month ends doesn’t lower that month’s bill; the next month starts from your new count. Notification emails are counted differently: on the month’s total, not the peak.
Price changes. We never raise your price automatically. Before any increase, we give you at least 60 days’ notice, and a yearly plan keeps its price until its next renewal. Read the price-change policy (draft).
