Work is counted in small, whole pieces, each with a published price that starts from what the work costs us, plus a margin. Many prices are a tiny fraction of a cent, and every piece is counted at its exact price. 1. Work is counted in small, whole pieces. Starlight measures what it does for you one piece at a time: a frame read from your recording, an item outlined in it, a picture cut out, a millisecond on a graphics processor, a second of storage. Each piece has its own price, and your statement lists how many of each you used. 2. Prices start from what the work costs us. Each price is what it costs us to do that piece of work, plus a margin. The margin also pays for the servers and services that keep Starlight running, so your statement lists only the work you asked for. 3. Tiny prices, counted exactly. Many pieces of work cost a tiny fraction of a cent, and some prices are measured in trillionths of a dollar, such as a megabyte stored for one second. Starlight counts every piece at its exact price, so your balance moves by what you actually used. 4. One balance that stays yours. The Starlight credits you buy pay for Sluice and Scan from the same balance, and they stay on your account until you spend them. If we cannot deliver what you paid for, we refund it. Each price list carries a version, and every line on a statement records the version it was priced at. Each charge is the exact price times the quantity, rounded up to the nearest millionth of a dollar.
