Donations
Every surplus cent from pay-to-deliver verifications is donated, split equally between The Internet Archive and the Electronic Frontier Foundation.
The first annual donation batch hasn't shipped yet. Pay-to-deliver verifications are collecting surplus into the charity pool now; it will be donated in the next annual cycle and listed verbatim here.
We don't show a running "$0 donated" counter to avoid creating an impression of a feature that doesn't exist yet. The page will populate as soon as the first batch is committed.
How the math works
When an inbox owner has enabled pay-to-deliver verification, the sender pays a small fee via Stripe Checkout. On every paid verification, Captchainbox keeps 40¢ + 3% of the gross. This covers Stripe processing fees plus a small operating margin so we don't lose money as the inbox owner raises their price. Everything above that pools into a charity fund and is donated annually, split 50/50 between the two charities below. Inbox owners receive no money; the incentive is friction, not profit.
On a 50¢ payment, ~8¢ goes to charity. On a $5 payment, $4.45. On a $20 payment, $19. The exact split of every payment is stored in our ledger; the table below shows what actually shipped.
