When it comes to purchasing digital products online, payment security is not just a nice-to-have — it is an absolute necessity. At Dargslan, we understand that your trust is the foundation of our business. That is why we have invested heavily in integrating two of the world's most trusted and widely used payment platforms: Stripe and PayPal.
In this article, we explain exactly how our payment system works, what security measures protect your transactions, and why we chose these two industry leaders as our payment partners.
Two Payment Options, One Seamless Experience
Every customer is different. Some prefer the speed and simplicity of paying with a credit or debit card. Others trust PayPal as their go-to digital wallet and never enter card details on individual websites. We respect both preferences, which is why Dargslan offers both options at checkout.
Stripe — Card Payments Made Simple
Stripe is one of the most trusted payment processors in the world, powering transactions for companies like Amazon, Google, Shopify, and millions of businesses globally. When you choose to pay with a card at Dargslan, Stripe handles the entire transaction.
Here is what happens behind the scenes when you pay with Stripe:
- You enter your card details on our secure checkout page. These details are sent directly to Stripe's servers — they never touch our servers or database.
- Stripe validates the card in real time, checking the card number, expiry date, CVV, and whether the card has sufficient funds.
- Stripe processes the payment using bank-grade encryption (AES-256) and returns a confirmation to our system.
- Your order is confirmed and your eBooks are immediately available for download in your customer account.
Stripe supports all major card brands:
- Visa
- Mastercard
- American Express
- Discover
- Diners Club
- JCB
Stripe also supports Apple Pay and Google Pay on compatible devices, meaning you can complete your purchase with a single tap or click if you have these digital wallets configured.
PayPal — The Trusted Digital Wallet
PayPal has been a household name in online payments for over two decades. With more than 400 million active accounts worldwide, PayPal is one of the most recognized and trusted payment methods on the internet.
When you choose PayPal at Dargslan checkout:
- You are redirected to PayPal's secure login page where you sign in to your PayPal account.
- You confirm the payment within the PayPal interface, using your PayPal balance, linked bank account, or linked card.
- PayPal sends the confirmation back to Dargslan, and your order is completed instantly.
- Your eBooks are available for immediate download.
The advantage of PayPal is that you never need to share your card or bank details with us — everything stays within PayPal's secure ecosystem. This adds an extra layer of buyer protection, including PayPal's own dispute resolution and purchase protection policies.
Automatic Tax Calculation with Stripe Tax
If you are purchasing from within the European Union, you may have noticed that VAT (Value Added Tax) is automatically calculated and applied to your order. This is not something we do manually — it is powered by Stripe Tax.
Stripe Tax automatically:
- Detects your location based on your billing address and IP geolocation.
- Applies the correct VAT rate for your country (e.g., 21% for Germany, 20% for France, 23% for Ireland, 27% for Hungary).
- Handles OSS (One-Stop Shop) compliance for EU cross-border digital product sales, ensuring we meet all EU tax obligations.
- Generates compliant invoices with proper VAT breakdowns for business and personal customers alike.
This means you always see the exact final price including all applicable taxes before you complete your purchase — no surprises, no hidden fees.
Security Measures That Protect You
Payment security is a multi-layered system. Here is a comprehensive overview of every security measure we have implemented:
PCI DSS Compliance
Both Stripe and PayPal are PCI DSS Level 1 certified — the highest level of security certification in the payments industry. PCI DSS (Payment Card Industry Data Security Standard) defines strict requirements for how payment data must be handled, stored, and transmitted.
Because we use Stripe and PayPal as our payment processors, your card details are handled entirely by these PCI-certified companies. Our servers never see, store, or process your raw card numbers. This dramatically reduces security risk and meets the gold standard for payment data protection.
SSL/TLS Encryption
Every page on Dargslan, including the checkout page, is served over HTTPS with TLS 1.3 encryption. This means all data transmitted between your browser and our servers is encrypted in transit, preventing anyone from intercepting your information.
You can verify this by checking the padlock icon in your browser's address bar. The padlock confirms that the connection is secure and that our SSL certificate is valid and up to date.
CSRF Protection
Every form submission on Dargslan, including the checkout form, is protected by CSRF (Cross-Site Request Forgery) tokens. This prevents malicious websites from submitting fake payment requests on your behalf. Each token is unique to your session and expires after use, making replay attacks impossible.
Rate Limiting
Our checkout endpoints are protected by database-backed rate limiting. This prevents automated scripts or bots from attempting to brute-force payments, test stolen card numbers, or abuse the checkout system. If an unusual number of requests are detected from a single source, the system temporarily blocks further attempts.
Content Security Policy
We implement strict Content Security Policy (CSP) headers that control which external resources can be loaded on our pages. This prevents cross-site scripting (XSS) attacks that could potentially inject malicious code into our checkout page. Only whitelisted domains — including Stripe's and PayPal's official JavaScript libraries — are allowed to execute scripts.
HTTP Security Headers
Beyond CSP, we implement a comprehensive set of security headers on every response:
- X-Content-Type-Options: nosniff — prevents MIME type sniffing attacks.
- X-Frame-Options: SAMEORIGIN — prevents our pages from being embedded in malicious iframes (clickjacking protection).
- Referrer-Policy: strict-origin-when-cross-origin — limits referrer information leakage.
- Permissions-Policy — restricts access to sensitive browser APIs like camera, microphone, and geolocation.
- Strict-Transport-Security (HSTS) — forces all connections to use HTTPS, preventing protocol downgrade attacks.
The Checkout Process Step by Step
Let us walk through the entire checkout process so you know exactly what to expect:
Step 1: Add Books to Your Cart
Browse our catalog, find the eBooks you want, and add them to your shopping cart. You can add individual books, bundles, or entire series. Your cart is persistent — it is saved to your account if you are logged in, so you can come back later without losing your selections.
Step 2: Review Your Cart
On the cart page, review your items, quantities, and prices. If you have a coupon code or gift card, enter it here to apply the discount before proceeding to checkout.
Step 3: Choose Your Payment Method
On the checkout page, you will see two clearly labeled options: Pay with Card (Stripe) and Pay with PayPal. Select the method you prefer.
Step 4: Enter Payment Details
If you chose Stripe, enter your card details in the secure payment form powered by Stripe Elements. If you chose PayPal, you will be redirected to PayPal's secure login page to authorize the payment.
Step 5: Confirm and Pay
Review the final total (including any applicable VAT calculated by Stripe Tax) and confirm your purchase. The payment is processed in seconds.
Step 6: Download Your eBooks
Once the payment is confirmed, you are redirected to your order confirmation page. Your purchased eBooks are immediately available for download in your customer library. You will also receive an order confirmation email with download links.
Supported Currencies
Dargslan prices are displayed in EUR (Euro), which is the base currency for all our products. Both Stripe and PayPal handle currency conversion automatically if your payment method uses a different currency. Your bank or PayPal account will show the converted amount based on current exchange rates.
Refund Policy for Digital Products
As a digital product store, we follow EU consumer protection regulations regarding digital content. Once you have downloaded your eBook, the right of withdrawal typically does not apply to digital products that have been delivered. However, if you experience any issues with your purchase — a corrupted file, a duplicate charge, or a product that does not match its description — please contact us and we will resolve the situation promptly.
Refunds, when applicable, are processed through the same payment method you used for the original purchase. Stripe refunds typically appear on your card statement within 5-10 business days. PayPal refunds are usually instant.
Why We Chose Stripe and PayPal
We evaluated several payment processors before selecting Stripe and PayPal. Here is why we chose these two:
Stripe
- Developer-first approach — Stripe's API is the most well-documented and reliable in the industry, allowing us to build a seamless, custom checkout experience.
- Built-in tax compliance — Stripe Tax handles EU VAT/OSS automatically, saving us and our customers the headache of manual tax calculation.
- Advanced fraud prevention — Stripe Radar uses machine learning trained on billions of transactions to detect and block fraudulent payments before they are processed.
- Global card support — Stripe supports cards from virtually every country and all major card networks.
- Instant payouts — Stripe's fast settlement means we can invest in new content more quickly, growing the catalog for your benefit.
PayPal
- Universal trust — PayPal is recognized by consumers worldwide as a safe payment method. Many customers specifically look for the PayPal option before purchasing.
- No card details needed — Customers who are hesitant to enter card numbers on websites can use PayPal as a secure intermediary.
- Buyer protection — PayPal's buyer protection program gives customers an additional safety net beyond our own policies.
- Mobile-friendly — PayPal's one-tap mobile experience makes purchasing on smartphones fast and convenient.
- Balance and bank transfers — Customers can pay from their PayPal balance or directly from a linked bank account, not just cards.
Frequently Asked Questions
Is it safe to enter my card details on Dargslan?
Yes. Your card details are sent directly to Stripe's PCI DSS Level 1 certified servers. Our website never sees or stores your raw card number. The connection is encrypted with TLS 1.3.
Can I use both Stripe and PayPal on the same account?
Absolutely. You can use Stripe for one purchase and PayPal for the next. There are no restrictions — choose whichever method you prefer each time you check out.
Do you store my payment information?
No. We do not store credit card numbers, CVV codes, or PayPal credentials. Stripe and PayPal handle all sensitive payment data on their own secure infrastructure.
What happens if my payment fails?
If a payment fails, you will see a clear error message explaining the issue (e.g., insufficient funds, incorrect card number, expired card). You can try again with the same or a different payment method. No charge is made for failed payment attempts.
Will I be charged extra fees?
Dargslan does not add any surcharges or processing fees to your order. The price you see — including VAT where applicable — is the price you pay. Your bank or PayPal may apply their own currency conversion fees if you are paying in a currency other than EUR.
Can I get an invoice for my purchase?
Yes. Every purchase generates an order confirmation that serves as your receipt. For business customers who need a formal VAT invoice, the order details include all required information including VAT amount and our company details.
Your Security Is Our Priority
We take payment security seriously because we understand what is at stake. Every technical decision we make — from choosing Stripe and PayPal over less-known processors, to implementing CSP headers and rate limiting, to using Stripe Tax for automatic VAT compliance — is driven by one goal: making your purchasing experience as safe, transparent, and hassle-free as possible.
