It's no longer possible to make payments directly from the Astute Manager however, as long as you're logged into the Astute Manager then clicking on any of the "buy" links or buttons will automatically log you into the website and load the checkout.
Astute Graphics takes the security of customer data very seriously and takes all legal and industry best practices to ensure this. When making a card payment, we securely and directly pass on customer-supplied card information to our reputable payment processor, Paddle via HTTPS / TLS (SSL secure connection). Astute Graphics and Paddle store only the final 4 digits of the card following successful payment for reference purposes; full card data is never held by either party.
