Steady helps independent media makers (such as bloggers and podcasters) earn money. Media makers can offer paid memberships through Steady - these are recurring payments to media makers to finance their work. Since these media makers are often lone warriors or small editorial offices, Steady takes care of billing, debiting and administration of these memberships for them.
If you see a charge from Steady, it is because you support a media maker with a regular contribution.
