Article 2 – Applicability
These Terms and Conditions apply to every offer made by SF Zero and to every Agreement concluded between SF Zero and the Customer. By placing an order, the Customer confirms that they have read and accepted these Terms.
SF Zero primarily supplies consumers (B2C) through the Website. Business orders (B2B) are accepted only upon request and become valid only after written confirmation. Such orders may be subject to separate pricing, delivery terms, warranties, and payment conditions.
Any deviation from these Terms is valid only if confirmed in writing by SF Zero. SF Zero reserves the right to refuse service, cancel orders, or limit quantities at its discretion.
Article 3 – The Offer
SF Zero takes reasonable care to ensure that all product descriptions, images, ingredient lists, and prices on the Website are accurate and complete. However, obvious errors, typographical mistakes, or pricing inaccuracies do not bind SF Zero.
Product images are intended for illustrative purposes and may vary slightly due to screen settings, supplier updates, or product improvements. Products with limited availability may be indicated as such.
Article 4 – Conclusion of the Agreement
An Agreement is concluded when the Customer completes the checkout process and payment has been successfully received or authorized. Following this, the Customer will receive an order confirmation via email.
SF Zero reserves the right to refuse, limit, or cancel orders for reasons including, but not limited to:
- suspicion of fraud or abuse
- incorrect or incomplete customer information
- insufficient stock availability
- payment authorization issues
- pricing or listing errors
- technical malfunctions or system errors
SF Zero further reserves the right to limit or prohibit orders that appear to be placed by dealers, resellers, or distributors.
Article 5 – Prices and Payment
All prices are listed in U.S. Dollars (USD). Applicable sales tax will be calculated at checkout where required by law.
Payments must be made using the methods offered on the Website, including credit cards, PayPal, and other secure payment providers. SF Zero reserves the right to modify prices at any time; however, price changes will not affect confirmed orders, except in cases of obvious pricing errors.
The Customer is responsible for providing accurate billing and payment information.
Article 6 – Subscriptions and Auto-Renewal
SF Zero offers subscription-based purchases of SF Zero Complete in addition to one-time orders. By selecting a subscription at checkout, the Customer authorizes SF Zero to automatically charge their selected payment method at the agreed interval until the subscription is canceled.
The following key terms apply to all subscriptions:
- The Customer's payment method will be charged automatically on each renewal date according to the selected billing cycle (e.g., every 30 days).
- The Customer will receive an email notification before each renewal charge.
- The Customer may cancel, pause, or modify their subscription at any time through their account or by emailing support@sf-zero.com. Cancellations take effect for all future billing cycles. Charges already processed before cancellation are not refundable, except as provided in the Return & Refund Policy.
- Subscription prices and discounts are clearly displayed at checkout and on the product page. SF Zero reserves the right to change subscription pricing with at least 30 days' advance notice. Existing subscribers will be notified by email and may cancel before any new price takes effect.
- Failure to maintain a valid payment method may result in delayed shipments or automatic suspension of the subscription.
Detailed subscription information, including step-by-step cancellation instructions, is available on the Subscription Policy page on the Website. In case of any conflict between this Article and the Subscription Policy, the Subscription Policy shall prevail to the benefit of the Customer.
Article 7 – Delivery and Shipment
Orders are processed Monday through Friday within 24 hours, excluding holidays. Delivery times stated on the Website are estimates only and are not guaranteed.
SF Zero may ship products directly from suppliers or fulfillment partners. As a result, orders may be shipped in separate packages and may arrive on different dates. Once an order has been shipped, the Customer will receive a Track & Trace code.
SF Zero is not liable for delays caused by carriers, customs authorities, or circumstances beyond its reasonable control. The Customer is responsible for providing accurate and complete shipping information. SF Zero is not liable for delivery issues resulting from incorrect or incomplete address details.
Unless otherwise required by law, risk of loss transfers to the Customer upon confirmed delivery by the carrier.
Optional insured shipping may be offered during checkout for an additional fee. If selected, insured shipping covers qualifying loss, theft, or irreparable transport damage during transit up to the stated insured amount.
