By default all of our plans go on month-to-month basis.
You can downgrade, upgrade, pause and continue any of the plans at any point of time. As long as you have an active subscription, the campaign credits you've acquired accumulate overtime if not used.
Each plan (exc. Universe) comes with the possibility of purchasing additional campaign credits for 250€$300 per credit.
The campaign credits can be used to unlock all the data points for any of your previous or upcoming campaigns.
