Terms of service for Rulecart: Kündigungsbutton
1. Provider and scope
Provider: Julius Scheuerer, c/o COCENTER, Koppoldstr. 1, 86551 Aichach, Germany, hello@rulecart.com. These terms apply to the Shopify app “Rulecart: Kündigungsbutton”. The app is for businesses only (§ 14 German Civil Code), not for consumers.
2. Service
The app adds a cancel link and a cancellation form to a Shopify store, confirms cancellations with a receipt page and an email, and shows them to the merchant. Features and plans are described in the Shopify App Store. Billing, cancellation and plan changes run through Shopify; the app can be uninstalled at any time.
3. No legal advice
The app is a tool. It is not legal advice and does not guarantee that a store meets all legal duties. The merchant checks whether the link, form and texts fit their store and stays responsible for their duties towards consumers.
4. Merchant duties
The merchant switches the link on in the theme, sets an email address for copies, handles incoming cancellations and keeps a second way to cancel (for example by email) for times when the app is unavailable. If the app is not active for a store, the cancellation page names the merchant's email address.
5. Availability
We run the app with ordinary care and monitoring but do not owe a specific availability. Where possible we announce maintenance in advance.
6. Liability
We are liable without limit for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act and where we gave a guarantee.
For slight negligence we are liable only for breach of essential contractual duties (duties whose fulfilment makes the contract possible and on which the merchant may rely), limited to the typical, foreseeable damage. Otherwise liability for slight negligence is excluded.
7. Data processing
For the data that the merchant's customers send through the form, the merchant is the controller and we are the processor. For every merchant on every plan, the European Commission's standard contractual clauses under Art. 28(7) GDPR apply (Implementing Decision (EU) 2021/915, https://eur-lex.europa.eu/eli/dec_impl/2021/915/oj), with the annexes below. They are agreed when the app is installed.
8. Changes, law, venue
We announce changes to these terms at least 30 days in advance in the app or by email; the merchant can uninstall before. German law applies. Place of jurisdiction for merchants is Cologne, Germany.
Annex I: Parties
Controller: the merchant who installs the app (shop domain and email from Shopify).
Processor: Julius Scheuerer, c/o COCENTER, Koppoldstr. 1, 86551 Aichach, Germany, hello@rulecart.com.
Annex II: Description of the processing
Data subjects: the merchant's customers who cancel through the form. Data: name, contract, type of cancellation, the reason where given, requested end of the contract, email address, reference, time of receipt, language. Purpose: to receive, confirm and store cancellations and make them available to the merchant. Duration: each cancellation is deleted three years after the end of the calendar year of its receipt (received in 2026: deleted from 1 January 2030, German time); earlier on a deletion request through the merchant and after an uninstall, when Shopify triggers it (after 48 hours). Deleted data leaves the backups within 30 days.
Annex III: Technical and organisational measures
Encrypted transport (TLS); servers in Germany with a firewall and key-only login; database only on an internal network; daily encrypted backups to a second site with a monthly restore test; access only by the provider; logs without the content of cancellations; abuse protection on the form; deletion through Shopify's privacy webhooks.
