The trial, and what happens when it ends
Fourteen days, no card. Nothing is charged at the end because nothing was collected.
The trial runs on the Growth plan for fourteen days with the limits open, so you see the product rather than a cut-down version of it. No card is taken, so nothing can be charged when it ends.
If you do not subscribe
The workspace becomes read-only. It is not deleted, every record stays readable, and export keeps working — including on the last day. Data you put in is yours and leaving with it is a feature, not a request.
Changing plan
Plan changes take effect from the start of the next period. Cancelling stops the renewal and the subscription runs to the end of the period you have already paid for.
If this did not answer it, open a ticket from your workspace — it arrives with your account attached, so nobody has to ask you which agency you are. Support is included on every plan.
