Terms of Service for the Shopify app “Extra Carts”.
(1) These terms govern use of the Shopify app “Extra Carts” of Q4 Reach Labs GmbH, Berthold-Litzmann-Str. 12a, 80995 Munich, Germany (the “Provider”) by merchants acting as businesses (§14 German Civil Code); consumer use is excluded. (2) The contract is formed on app installation and acceptance of these terms and the Data Processing Agreement (DPA). (3) The merchant’s relationship with Shopify remains unaffected; billing runs through the Shopify platform.
(1) Extra Carts automatically sends product-recommendation emails to a shop’s existing customers (post-purchase recommendations of similar goods within the meaning of §7(3) of the German Act against Unfair Competition, UWG), measures clicks and attributed orders, and provides a dashboard with a complete evidence trail. (2) Product selection uses the shop’s own purchase-pattern data only; price is not a selection criterion. (3) No guaranteed outcomes: the Provider owes diligent operation of the service, not any particular revenue. (4) Sends occur only where a suitable legal basis exists; if unclear, no send.
(1) The following applies: “Extra Carts charges 9% of the value of each qualified order it demonstrably brings back to your store (merchandise subtotal, excluding shipping and taxes). No subscription, no setup fee, no other charges. An order is billed at the earliest 14 days after payment; orders cancelled or fully refunded within those 14 days are never billed, and later refunds are credited proportionally. Fees are billed monthly and never exceed your approved monthly cap. Your rate can only ever decrease, never increase.” (2) Watch Mode: no fees in the first 14 days after your first send; amounts accrued then are forgiven, never billed retroactively. (3) Cap: you set a per-billing-cycle cap (default USD 200). The cap is a true price ceiling: fees above it are forgiven, never carried over, and are disclosed to you. If fees exceed the cap in two consecutive cycles, sending pauses at the end of the following cycle until you adjust the cap; sending never pauses mid-cycle for billing reasons. (4) Grandfathering: rate cuts apply to existing merchants; rate increases toward an installed merchant are excluded. (5) Orders below €5 qualified value are not billed. (6) Payment processing runs via Shopify (the plan approved at install governs).
(1) Operate the shop lawfully and keep the customer data stored in Shopify — especially the marketing-consent status — accurate. (2) The merchant remains the data controller for end-customer data; the Provider acts as processor under the DPA. (3) The merchant does not use the service for goods or content whose promotion is unlawful.
The Provider operates the service with reasonable availability; maintenance windows and circumstances outside the Provider’s control (notably Shopify or email-service-provider outages) remain reserved. No guaranteed service levels exist.
The Data Processing Agreement (DPA) applies, including §11 DPA (anonymized aggregate statistics; no training of ML/AI systems on merchant data absent Shopify’s prior written consent) and the staged annex model (§12 DPA).
(1) The contract runs indefinitely and ends on uninstall — any time, no notice period. (2) Sending stops immediately on uninstall; orders attributed after uninstall are not billed; accrued due fees remain unaffected. (3) Data deletion per §9 DPA.
Changes to these terms are announced at least 30 days before taking effect, in text form and in the dashboard. If you object, you may terminate (uninstall); §3(4) (no rate increases) is exempt from changes.
(1) The Provider is liable without limit for intent, gross negligence, injury to life, body or health, and under product-liability law. (2) For slightly negligent breaches of essential contractual duties (cardinal duties), liability is limited to the typical, foreseeable damage. (3) Otherwise liability is excluded; in particular there is no liability for the merchant’s lost profits.
German law applies. Venue is Munich where the merchant is a registered trader. Amendments require text form. Should a provision be invalid, the remainder of the contract stays effective. In case of discrepancies between language versions, the German version prevails.
