You can change your plan any time, no support ticket required.
How proration works
If you upgrade mid-cycle, we charge the difference, prorated to the day. If you downgrade, we apply credit to your next invoice.
Cancelling
Open Settings → Billing → Cancel plan. Your account drops to the Free tier at the end of the current billing period — you keep paid features until then.
What happens to my data?
Nothing. Free accounts keep all their content. We never delete data when a subscription ends.
