4. Payment Handling

4.1 Merchant of Record

Whether you buy a Standard License through the Website or your Standard License is automatically renewed, all payments will be handled through our Merchant of Record, Paddle. As a Merchant of Record, Paddle enables us to sell Standard Licenses for Centias worldwide in a secure and timely manner, while being compliant with local regulations. Paddle will process your payments and send you an invoice after completing your transaction. You will find all transactions made through the Website marked with PADDLE.NET*CENTIAS in your bank statement or credit card statement. For further information please visit paddle.com. Please also make sure to read Paddle's own terms of service.

4.2 Pricing

Prices for the Standard License will be shown based on your location in your local currency. Specific local pricing may apply in several countries. If no local pricing exists for your location it will default to pricing for Germany in Euros and be converted to your local currency instead. Paddle will handle currency conversion automatically. Please be aware that your bank may charge you with additional currency conversion fees or interchange fees.

All prices are exclusive of VAT or any additional taxes. Any taxes will be calculated by Paddle as soon as you enter your invoice address and proceed to checkout. You may also enter business information and a VAT number in the payment process for Paddle to take into account for any tax related pricing.

Prices are subject to change. We will inform you of any pricing changes that would affect you six weeks beforehand by email. Please note, that price differences caused by currency fluctuations and automatic currency conversions do not fall under price changes.

4.3 Standard License Subscription

Whenever you buy a Standard License for the software through our Website, automatic renewal is activated, which means the Standard License will be renewed annually and you will be charged the respective amount. If the automatic renewal is not cancelled on time you will be charged by Paddle for the price of a one-year Standard License. Please refer to the Standard License Agreement document for further information.

5. Delivery and Provision of purchased Standard Licenses

After your purchase has been successful we will create a User account for you with the purchased license attached to it. We will then send you further instructions by the email you've provided us with during checkout. Should an account already exist with that email the license will be added directly to that account instead.

The Software is downloadable through the publicly available NuGet.org package feed. Further instructions on how to download the Software can be found in the documentation.

Updates to the Software are also available through NuGet's package manager.

Your User account will be created directly upon completion of the purchase. You will receive an email with further details that allows you to complete the registration process.

Should you already have a User account upon purchase, any new license you purchase will be added to that account instead. An account will be identified by the email address used during checkout.

6. Refund Policy

If you purchase the Standard License you will have the right to withdraw from your contract within 14 days. We do not require any reasons for withdrawal.

6.1 Consequences of Withdrawal

If your withdrawal complies with the terms outlined in these T&C, you will receive a refund of the original amount through the same transaction method you used during purchase. Please note that refunds are handled by our payment provider Paddle.

After withdrawal your right to use the Software with an active Standard License will expire immediately, as such production domain usage will cease to function.

6.2 Withdrawal Limitations

If you have set a production domain in your account for the purchased Standard License during the 14-day period, withdrawal will not be possible.

During purchase you will be required to acknowledge our Refund Policy and this limitation.
