Immediate Delivery After Payment
After successful payment confirmation, purchased digital materials are made available electronically.
All guides, courses, documents, and other learning materials offered through Calthrenia are digital. No physical shipping or delivery is involved.
Payments are processed by a third-party payment provider, such as Stripe, PayPal, Airwallex, or another payment provider available through the website.
We do not store your full payment card details.
Once the applicable payment provider confirms that the payment has been successfully completed, the purchased digital materials will be made available through a download link, email delivery, account access where available, or another electronic delivery method indicated during the purchase process.
In most cases, access is provided shortly after payment confirmation.
However, delivery may occasionally be delayed due to:
payment verification or processing;
delays in communication between the payment provider and our website;
email delivery delays;
temporary technical issues;
security or transaction review procedures;
incorrect customer information provided during checkout.
Access is provided only after we receive confirmation of a successful payment from the applicable payment provider.
How to Access Your Materials
After completing your purchase and receiving successful payment confirmation, you will normally receive a confirmation email containing information about your order and instructions for accessing the purchased materials.
Depending on the digital material and website functionality, access may be provided:
through a download link sent to the email address used during checkout;
through your Calthrenia user account, where account-based access is available;
directly through an order confirmation page;
or through another electronic delivery method clearly indicated during the purchase process.
Download links and access instructions may be unique to your order and are intended only for the purchaser.
We recommend keeping your order confirmation email and purchase information for future reference.
You are responsible for providing a valid and correctly entered email address during checkout.

Where materials are provided through account-based or online access, continued availability may depend on the access period described at the time of purchase.
Digital materials are intended for individual, self-paced study unless otherwise stated.
