§ 1 Scope

(1) These Terms and Conditions (hereinafter “T&C”) apply to all contracts between Cambium Holding UG (haftungsbeschränkt), brand WiderrufButton (hereinafter “Provider”), and the customer regarding the use of the SaaS service “WiderrufButton”.

(2) WiderrufButton is intended exclusively for entrepreneurs within the meaning of § 14 of the German Civil Code (BGB). Use by consumers is not provided for. By registering, the customer confirms that they are an entrepreneur.

(3) Deviating, conflicting or supplementary terms and conditions of the customer shall only become part of the contract if the Provider has expressly agreed to their validity in writing.

§ 2 Subject of the contract

(1) The Provider supplies the customer with a SaaS-based JavaScript widget that integrates a legally compliant withdrawal function pursuant to § 356a BGB (in conjunction with EU Directive 2023/2673) into the customer’s online shop.

(2) The widget enables the shop’s end customers (consumers) to submit withdrawal declarations through a two-step process. The Provider supplies the technical infrastructure, the widget, the API and the management dashboard.

(3) WiderrufButton does not provide legal advice. The Provider supplies a technical solution. The legal assessment and implementation of withdrawal obligations rest with the customer.

§ 3 Registration and conclusion of contract

(1) Registration takes place via the website widerrufbutton.net using an email address and a magic-link procedure.

(2) The contract is concluded upon successful registration and the selection of a plan.

(3) The customer is obliged to provide truthful information when registering and to keep their data up to date.

The Provider offers the following plans:

All prices are net prices plus statutory VAT.

§ 5 Prices and payment

(1) Billing is monthly or annual, depending on the chosen billing period. A discount is granted for annual payment.

(2) Payment is processed via the payment service provider Stripe. The following payment methods are available: credit card and SEPA direct debit.

(3) In the event of late payment, the Provider reserves the right to restrict access to the service after prior reminder. Withdrawals already submitted remain unaffected by any suspension.

§ 6 Free trial period

(1) New customers receive a free 14-day trial period with the full premium feature set (custom colours, custom branding without “Powered by”, unlimited withdrawals).

(2) After the trial period ends, the withdrawal button remains permanently free and legally compliant to use, albeit within the limited Free scope (10 withdrawals/month, standard design, “Powered by WiderrufButton” notice). The full feature set is available with a paid plan. There is no automatic conversion into a paid plan without the customer’s express consent.

§ 7 Term and termination

(1) The contract is concluded for an indefinite period and may be terminated monthly at the end of the respective billing period.

(2) Termination can take place at any time via the termination button in the dashboard under “Settings” → “Cancel subscription” (pursuant to § 312k BGB – termination button requirement).

(3) After termination, access remains until the end of the paid period. Thereafter the widget is deactivated and the dashboard is switched to read-only access.

(4) The right to extraordinary termination for cause remains unaffected.

§ 8 Availability

(1) The Provider aims for a service availability of 99.5% on an annual average. This excludes scheduled maintenance windows, which are announced in advance where possible.

(2) No guarantee is given for uninterrupted availability. The Provider is not liable for outages caused by force majeure, network disruptions or the actions of third parties.

§ 9 Customer obligations

(1) The customer is responsible for properly embedding the widget in their online shop and ensuring that the withdrawal button is accessible to consumers.

(2) The customer is obliged to process incoming withdrawals within the statutory deadlines. WiderrufButton merely provides the technical infrastructure.

(3) The customer may not use the widget improperly, in particular not to process data that goes beyond the intended purpose (withdrawal).

§ 10 Liability

(1) WiderrufButton does not constitute legal advice. The Provider gives no warranty that use of the widget fully satisfies all of the respective customer’s legal requirements. The customer is obliged to ensure legal compliance independently or with legal counsel.

(2) The Provider’s liability for slight negligence is excluded, unless material contractual obligations (cardinal obligations) are breached. In the event of a breach of cardinal obligations, liability is limited to the foreseeable damage typical for the contract.

(3) In any case, liability is limited to the total amount of the remuneration paid by the customer in the last 12 months.

(4) The above limitations of liability do not apply to damage resulting from injury to life, body or health, nor to intentional or grossly negligent conduct.

(5) No warranty for functionality and availability. The Provider supplies the widget “as is”. There is no claim to continuous availability, undisturbed operation or error-free function of the widget. In particular, no liability is assumed for impairments caused by browsers, end devices, networks, third-party scripts, CDN outages, content security policies, caching systems, ad blockers or other factors outside the Provider’s sphere of influence. The liability limitations of this paragraph apply only within the scope of paragraphs (2) to (4); liability for the breach of material contractual obligations (cardinal obligations) as well as for intent, gross negligence and damage resulting from injury to life, body or health remains unaffected.

(6) No liability for warning letters or legal consequences. The Provider assumes no liability for warning letters, lawsuits, fines or other legal measures imposed on the customer or third parties due to the use or non-use of the widget. The customer is themselves obliged to ensure the legally compliant integration and configuration of the widget as well as compliance with all statutory requirements (including, but not limited to, § 356a BGB, EU Directive 2023/2673 and national implementing laws).

(7) No liability for data loss. The Provider is not liable for the loss of data insofar as the damage is based on the customer’s failure to perform data backups and thereby ensure that lost data can be restored with reasonable effort.

(8) Confirmation of receipt by email. Confirmations of receipt are sent via third-party providers (SMTP providers). The Provider gives no warranty for delivery by these third-party providers, for spam-filter classification, delayed delivery or outages of the email infrastructure. The customer is obliged to check the confirmation-of-receipt log in the dashboard regularly and, in the event of failed delivery, to ensure notification of the consumers independently.

§ 11 Data protection

The processing of personal data takes place in accordance with our privacy policy.

Insofar as the Provider processes personal data on behalf of the customer within the scope of the service (withdrawal data of end customers), a data processing agreement pursuant to Art. 28 GDPR is concluded. The DPA is available in full and can be saved or printed as a PDF.

§ 12 Amendments to the T&C

(1) The Provider reserves the right to amend these T&C with effect for the future, provided that the amendment is reasonable for the customer, taking into account the interests of the Provider.

(2) The customer will be informed of amendments by email at least 4 weeks before they take effect. If the customer does not object within 4 weeks of receiving the amendment notice, the amended T&C are deemed accepted. The Provider will inform the customer of the right to object and the significance of the deadline in the amendment notice.

§ 13 Final provisions

(1) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods.

(2) The place of jurisdiction for all disputes arising from and in connection with this contract is, to the extent legally permissible, the Provider’s registered office.

(3) Should individual provisions of these T&C be or become invalid, the validity of the remaining provisions shall not be affected thereby.

Last updated: June 2026. These T&C apply to the use of WiderrufButton by entrepreneurs within the meaning of § 14 BGB. For questions: info@ateliernodus.com.

Note: WiderrufButton is not legal advice and not a law firm. We provide a technical solution that reflects the statutory requirements of § 356a BGB to the best of our knowledge; the service alone cannot guarantee complete legal certainty for your individual shop. A legal review is recommended.

Cambium Holding UG assumes no liability for legal consequences arising from the use of the widget. Details in § 10 Liability.
