Your reading account

Everything the meter knows is in this browser: the balance, every page opened with the share read and what it cost, what you declined and why, and your top-ups. Export it as JSON; nothing is sent anywhere unless you choose to. A new browser or cleared site data starts again with the starting credit.

How the meter works, and why it works this way, is on the billing model. The account needs JavaScript: the balance lives here, not on a server.
