Plan balance is valid for 30 days from payment; anything unused at the end of the period clears. Checks draw on plan balance first and fall back to permanent balance. The plan renews every 30 days — sign in, open Billing history and turn off auto-renewal to stop the next charge; your current period and balance are unaffected.
Permanent top-ups can be paid by card or cryptocurrency. 30-day plans use secure hosted card checkout and renew automatically every 30 days. Balance is added after payment confirmation.
