Where your card details live
They live with Polar, and nowhere else. myClerkBook never receives, transmits or stores a card number. Card details are entered into Polar’s own payment form inside the checkout window, and what reaches myClerkBook is the outcome of the payment, not the instrument.This is a deliberate architectural boundary rather than a limitation. Keeping
card data entirely out of myClerkBook is what keeps it out of scope for card
handling, which is the strongest guarantee available: we cannot lose what we
never hold.
What you can pay with
Polar accepts major debit and credit cards. The exact set available to you depends on your country and is shown in the payment form at checkout, so the form is the authority, not this page.Changing your card
Adding or changing a saved card is done through Polar’s own portal, reached from any receipt Polar sends you. That hand-off exists for the same reason as everything above: the page that takes a card number has to be Polar’s.Currency
Plans are priced in US dollars. Your bank converts at its own rate on the day, and may add its own foreign-transaction fee. Neither the rate nor the fee is set by myClerkBook or by Polar.The currency your plan is priced in has nothing to do with the currency your
books are kept in. A book kept in ZAR is unaffected by the plan being billed
in USD.
