What personal data we collect and why we collect it
Purchases: When you purchase digital products from our store, we collect the information required to process your order and deliver your product. This includes your name, email address, billing address, and payment details. We use this information to process transactions, prevent fraud, send you purchase receipts, and provide you with access to your digital downloads.
Cookies: We use cookies to track your cart contents as you browse our site. These temporary cookies contain no personal data and simply allow the e-commerce checkout system to function smoothly during your visit.
Embedded content from other websites: Pages on this site may include embedded content (such as videos or images). Embedded content from other websites behaves exactly as if the visitor has visited that website. These external websites may collect data about you, use cookies, embed additional third-party tracking, and monitor your interaction with that embedded content.
Who we share your data with: Your personal data is not shared with third parties for marketing purposes. Payment and billing information is shared securely with our authorized payment processing partners strictly to facilitate your transactions.
How long we retain your data: We retain purchase records and related billing information for as long as necessary for administrative, legal, tax, and accounting purposes.
What rights do you have over your data? You can request an export of the personal data we hold about you (such as your purchase history and email address). You can also request that we erase any personal data we hold about you. This does not include any data we are legally obliged to keep for administrative, tax, or security purposes.
