Terms and conditions

Translation: This English text is provided for convenience. Only the German version is legally binding; in case of differences the German version prevails. Mandatory consumer protection rules of your country of residence remain unaffected.

1. Scope and provider

These terms apply to all contracts concluded via this website (Stackpick). Provider and contracting party: Sunfield – owner: Lukas-Domenik Sonnenfeld, address see Imprint, email: sunfieldsupport@gmail.com (“we”). This offer is directed at consumers and businesses. German law applies (see section “Final provisions”).

2. Countries

We supply consumers with a billing address in: Germany, Austria, Belgium, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Liechtenstein, Norway, Iceland. Consumers in other countries (e.g. the United Kingdom) cannot order, for tax reasons; if such an order is placed, we cancel it and refund the full amount. Businesses may order worldwide except sanctioned countries; EU businesses need a valid VAT ID. We supply digital products and services only – no physical goods, no customs.

3. Conclusion of contract

The packages shown are not a binding offer. Online purchase: on the order page you check package and price, enter your email and country and confirm the required notes. By clicking “Order with obligation to pay” and completing payment with Stripe you make a binding offer; we accept it by order confirmation email, at the latest within two working days after payment. Enquiry: for packages with the button “Enquire” you receive our offer by email; the contract is concluded when you accept it.

4. Prices and payment

All prices are final prices in EUR. As a small business under § 19 German VAT Act no VAT is charged. Any import VAT, local taxes or fees in your country are not charged by us; for businesses outside Germany the reverse-charge rules of your country apply. Payment in advance via Stripe (card, Apple Pay, Google Pay, PayPal and more); for offers by email, payment by invoice.

5. Delivery of digital content and rights of use

Digital content is delivered as a download link by email, usually the same day, at the latest two working days after payment; the link is valid for at least 14 days. You receive a simple, non-transferable, unlimited right of use within the scope of the licence described for the package. Resale, sharing and public distribution are only permitted where the licence expressly allows it. We provide updates required for conforming use.

6. Right of withdrawal

Consumers have a right of withdrawal as set out in the withdrawal policy; you can also withdraw via “Withdraw from contract” in the footer of every page.

7. Warranty and liability

Statutory warranty rights apply. We are liable without limitation for intent and gross negligence, for injury to life, body or health and under the Product Liability Act; for slight negligence only for breach of essential contractual obligations and limited to the typical, foreseeable damage. Our content and tools help you organise things; they do not replace legal, tax, financial or medical advice.

8. Final provisions

Contract language: German and English; the German version of these terms prevails. German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers this choice of law applies only insofar as it does not deprive them of the protection of mandatory provisions of the country of their habitual residence. We do not participate in consumer arbitration proceedings.
