2. Seller of Record
Digital products offered on this website are sold by Paddle.com Market Ltd ("Paddle") as the Merchant of Record. When you purchase a product, your contract of sale is with Paddle, not with WeissExplorers. Paddle handles payment processing, invoicing, tax collection and remittance, and first-line purchase support.
Paddle's Buyer Terms and Conditions apply to your purchase and are available at paddle.com. WeissExplorers is the supplier and author of the product content.
3. Products
The products offered are digital documents (PDF and associated files) containing technical documentation, build instructions, drawings, and bills of materials. Product scope is described on the respective product page.
4. License
Purchase grants you a non-exclusive, non-transferable license for personal, non-commercial use. You may print and store copies for your own use. You may not resell, redistribute, publish, or share the files, in whole or in part, or use them as the basis for commercial manufacture without a separate written agreement.
5. Technical Content — No Warranty of Fitness
The documentation describes a system built and tested by WeissExplorers under specific conditions. It is provided for informational purposes.
Building, modifying, and operating water filtration and pressure systems involves risk. You are responsible for verifying that any component, material, or method is suitable for your application, complies with applicable law and standards in your jurisdiction, and is safe under your operating conditions. Water treated with a system built from this documentation is not guaranteed to be potable.
WeissExplorers accepts no liability for damages, injury, or loss arising from the use of, or reliance on, the documentation, except in cases of intent or gross negligence, and except where liability cannot be excluded under mandatory law.
6. Intellectual Property
All content on this website and in the products — text, drawings, photographs, designs — is the property of WeissExplorers unless otherwise noted. "WeissExplorers" is a registered trademark.
7. Applicable Law
Austrian law applies, excluding conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer protection provisions of your country of residence remain unaffected. Note that for purchases, Paddle's terms and their choice of law govern the sales contract.
8. Changes
These terms may be updated. The version in effect at the time of your purchase applies to that purchase.
