Cancellation is scheduled for the end of the paid period, with a confirmation email and date; until then you can reactivate. Full refund within 14 days.
Cancelling
Under Billing, use "Cancel subscription". Cancellation is scheduled for the end of the period already paid: you keep access until that date, with no future charges, and receive an email confirming the day access ends. There is no lock-in or cancellation fee.
Reactivating
While the paid period has not ended, "Reactivate" undoes the schedule and the subscription continues normally at the next charge. After the period ends, just choose a plan again: the company's data is still there, nothing is deleted by cancelling.
Refund
The guarantee is 14 days: if you request cancellation within the first 14 days of a paid subscription, the amount is refunded in full through the same payment method. Details are in the Refund Policy.
