As no padlock is shown we appreciate that this is a reasonable question however, the answer is yes, Astute Manager is entirely secure for purchases. Astute Graphics takes the security of customer data very seriously and takes all legal and industry best practices to ensure this.
The Astute Manager uses the same payment and security system that our website uses. So if paying via the Astute Manager or through the website, we securely and directly pass on customer-supplied card information to our reputable payment processor, Stripe via HTTPS / TLS (SSL secure connection). Astute Graphics receives only the final 4 digits of the card for reference from Stripe following successful payment for reference purposes; it never stores full card data.
Stripe have been audited as a PCI level 1 service provider. For more information about their process, please refer to Security at Stripe
