Change plan, cancel, find an invoice

Sign in on diktun.com, then Subscription. That is where you change plan, update your card, find your invoices and cancel.

Changing plan takes effect immediately. Moving up a plan, the difference is pro-rated.

Cancelling erases nothing. The service stays active until the end of the period you already paid for, nothing is charged afterwards, and the account falls back to the free plan: you keep your data, your vocabulary and a reduced allowance.

If a payment fails, your access is not cut off while the bank retries. Cutting off someone's working tool over an expired card would be the surest way to lose them.

Nothing is billed for going over. You cannot receive an invoice higher than your subscription.
