Last updated: June 19, 2026 · Nusselt Management GmbH
These Terms and Conditions (Terms) apply to all agreements between Nusselt Management GmbH, Drachenseestr. 4a, 81373 Munich (hereinafter "Provider") and customers for paid use of the WordPress plugin WP Dienstplan in the Basic or Pro version (hereinafter "Plugin").
Deviating, conflicting, or supplementary terms and conditions of the customer do not become part of the contract unless the Provider expressly agrees in writing.
The free Basic version of the Plugin is available on WordPress.org and is subject exclusively to the GNU General Public License v2 (GPL). These Terms apply only to paid licenses.
The presentation of the Plugin and prices on wp-dienstplan.de does not constitute a binding offer but rather an invitation to submit an order.
The ordering process is handled through the subscription management platform Fakturia (a product of Luminea IT Services GmbH, Mühlweg 1, 82054 Sauerlach). By submitting the order in the Fakturia checkout, the customer makes a binding offer to conclude a license agreement. The contract is formed when the Provider confirms the order via email and transmits the license key.
The Provider reserves the right to reject orders without providing reasons, particularly in case of suspected misuse.
The contract language is German. The contract text is not separately stored after contract formation; the customer receives the Terms as part of the order confirmation via email.
All prices are inclusive of applicable sales tax (currently 19% in Germany). Annual licenses are offered as follows:
The free version of the plugin remains available at no license fee. Which features are included in each tier is defined in the current pricing overview at wp-dienstplan.de and the feature list (as published at the time of contract formation). In the plugin under “Dienstplan → Plans”, the same comparison table is shown; features not yet available are marked “Coming soon”.
Billing is annual in advance. Invoices are issued by Nusselt Management GmbH and sent via email.
Payment can be made through the following methods:
The payment methods actually available may vary depending on country and order and are displayed in the checkout.
For all payments except PayPal, the Provider uses the payment processor Stripe Payments Europe, Ltd., 1 Grand Canal Street Lower, Grand Canal Dock, Dublin D02 H210, Ireland. Stripe processes payment data on behalf of the Provider. Stripe's terms of use and privacy notices supplement these terms (stripe.com/de/privacy).
Payments via PayPal are processed directly through PayPal (Europe) S.à r.l. et Cie, S.C.A., 22–24 Boulevard Royal, 2449 Luxembourg. PayPal's terms of use and privacy notices supplement these terms (paypal.com/de/privacy).
If the customer chooses SEPA Direct Debit as the payment method, they grant the Provider a SEPA Base Direct Debit Mandate for recurring payments of the annual license fee.
The customer agrees to receive advance notice of debit at least 2 days before payment collection via email. This deviates from the standard statutory notice period of 5 business days; the customer explicitly consents to this shortened period upon issuing the mandate.
The customer is entitled to reimbursement from their bank in accordance with agreed terms. They may request reimbursement of the debited amount within 8 weeks from the date of debit. The terms agreed with the customer's bank apply in this regard.
Notice: By confirming payment in the checkout, the customer issues the SEPA standing order mandate and agrees that Nusselt Management GmbH and Stripe, the payment processor, may collect payments from their account via direct debit in accordance with these Terms. The customer simultaneously instructs their bank to debit their account accordingly.
If a payment cannot be collected or the customer defaults on payment for any reason, the Provider is entitled to temporarily deactivate the license key and thus the activation-based Pro features of the Plugin until the outstanding amount is paid in full. All stored data (schedules, members) remain and are still accessible via the free Basic version.
In case of chargeback or rejected payment, the customer bears the resulting bank fees of the respective payment processor (Stripe or PayPal) in actual amount. Additionally, the Provider charges a processing fee of EUR 20.00 per chargeback operation.
The assertion of further damages is reserved. The customer has the right to prove that damage has not occurred or has occurred in substantially less amount.
The Provider reserves the right to change license prices. Price changes are communicated to the customer via email to the registered address at least 6 weeks before the next renewal date. Changed prices apply from the next renewal period.
If the customer does not object to the price change by the renewal date, this is considered acceptance. The customer has the right to terminate the contract before the renewal date (Section 9 of these Terms) if they do not agree to the price change.
Upon purchase, the customer receives a non-exclusive, non-transferable license to use the Plugin on the websites defined in Section 7.2 for the duration of the paid license period.
The PHP source code of the Plugin is licensed under GPL v2 and freely accessible. The commercial license entitles the holder exclusively to use activation-based features and receive updates and support for the license duration. The buyer acquires no ownership of the software.
Each license allows simultaneous activation on one production website and one staging or development environment of the same project. Activation on additional independent websites requires an additional license for each.
Staging environments are automatically recognized by the Plugin through typical features (URL patterns such as .local, .staging, dev. or WordPress environment type) and consume the staging slot, not the production slot.
During the license period, the customer is entitled to all published Plugin updates and email support at Cookie settings info@wp-dienstplan.de. Updates are installed via the WordPress dashboard.
After expiration of the license, the last installed Plugin version and the free Basic version may continue to be used. No entitlement to further updates or support exists after expiration.
Pro customers receive priority processing of support inquiries (Priority Support).
The license agreement has a minimum term of one year from contract formation. It automatically renews for an additional year unless terminated in a timely manner (Section 9.2). The customer is reminded of the renewal date via email. At the renewal date, the license fee for the new year is automatically deducted (SEPA standing order) or charged via the selected payment method.
The customer may terminate the contract at any time at the end of the current contract year. Termination must be received by the Provider no later than 1 month before the respective renewal date to be effective for the current renewal period. Later termination becomes effective at the next possible date (end of the following contract year).
The following methods are available for termination:
The Provider confirms receipt of termination via email. Already paid amounts are not refunded upon termination at contract end; the license remains active until the original expiration date.
The Provider is entitled to terminate the contract for cause without notice, particularly in case of material breach of Section 7.3 of these Terms (unauthorized transfer or manipulation of the license key). In case of extraordinary termination by the Provider due to a reason attributable to the customer, no refund of already paid amounts is due.
Upon expiration or termination of the license, the Pro features of the Plugin are automatically deactivated. All stored data (schedules, members, shifts) remains completely intact and continues to be readable via the free Basic version. No data is lost.
The following right of withdrawal applies exclusively to customers who are consumers within the meaning of Section 13 of the German Civil Code (BGB). Customers ordering as entrepreneurs (Section 14 BGB), legal entities under public law or special public-law funds – including associations, municipalities, aid organisations and fire departments – do not have a statutory right of withdrawal.
Right of Withdrawal
If you are a consumer, you have the right to withdraw from this contract within fourteen days without providing any reason. The withdrawal period is fourteen days from the date of contract formation.
To exercise your right of withdrawal, you must inform us (Nusselt Management GmbH, Drachenseestr. 4a, 81373 Munich) by clear statement. You may use the "Withdraw from contract here" button in the footer of our website (wp-dienstplan.de/en/withdrawal.html), send an email to ihre-lizenz@wp-dienstplan.de, or contact us by post.
It is sufficient to send the notice of withdrawal before the withdrawal period expires.
Consequences of Withdrawal
If you withdraw from this contract, we shall refund to you all payments received from you without undue delay and in any case not later than fourteen days from the day on which the notice of your withdrawal of this contract was received. We shall use the same means of payment for the refund as you used for the original transaction, unless expressly agreed otherwise; you will incur no charges for this refund.
Expiration of Right of Withdrawal for Digital Content
Notice: The right of withdrawal expires early if the customer has explicitly confirmed during the ordering process that the Provider may begin executing the contract (provision of the license key and Plugin download) before the withdrawal period expires, and the customer has simultaneously confirmed their knowledge that they lose their right of withdrawal by this consent (Section 356(5) BGB – German Civil Code).
This confirmation is not currently captured separately in the checkout process. Whether the requirements of Section 356(5) BGB are met must be assessed on a case-by-case basis.
The Plugin is provided as software in its current version at the time of contract formation. The Provider warrants the Plugin's conformity to contract in accordance with the published feature description.
No warranty is provided that the Plugin will be compatible with future WordPress versions, PHP versions, or third-party plugins. Updates are regularly provided to maintain compatibility with current WordPress versions.
The limitation period for warranty claims is two years from contract formation.
The Provider is liable without limitation for damages arising from injury to life, body, or health and for damages based on intent or gross negligence. Liability under the German Product Liability Act (Produkthaftungsgesetz) remains unaffected.
In case of negligent breach of essential contractual obligations (cardinal duties), liability is limited to typical foreseeable damages. Otherwise, liability for slight negligence is excluded.
For all claims based on slight negligence, the Provider's liability is additionally capped at twice the annual licence fee paid by the customer in the current contract year, but no more than EUR 1,000.00 per claim. Liability for indirect damages, lost profits, or consequential damages is excluded to the extent permitted by law.
Liability for data loss is limited to the typical restoration costs that would have been incurred with regular and appropriate data backup by the customer. The customer is obliged to create regular backups of their entire WordPress installation, including the database, and to keep them at a location separate from the production system.
The Plugin is a tool to support shift scheduling. The Provider accepts no liability for the legal or regulatory conformity of the shift schedules actually created with the Plugin (for example compliance with working-time rules, minimum-wage rules, collective agreements, operational, fire-service, EMS or association regulations) – this responsibility lies with the customer (see Section 13a).
The Plugin assists in drawing up shift schedules; however, the customer alone is responsible for ensuring that the schedules they create comply with all applicable legal, regulatory and organisational requirements. This includes in particular:
The Provider does not provide legal advice. Where required, the customer must obtain professional legal advice, particularly regarding the lawful implementation of scheduling and data-protection requirements.
For information on the processing of personal data in connection with this contract and use of this website, please see our Privacy Policy.
When the customer installs and operates the Plugin on their own WordPress installation, the customer is the sole controller within the meaning of Article 4(7) GDPR for all personal data processed within the Plugin (e.g. data on employees, volunteers or members). The Provider has no access to such data and does not act as a processor unless a separate data processing agreement pursuant to Art. 28 GDPR is concluded in individual cases (e.g. during a support session in which the customer grants the Provider access to their WordPress installation).
The European Commission provides a platform for online dispute resolution (ODR), accessible at ec.europa.eu/consumers/odr. Our email address is: info@wp-dienstplan.de.
We are neither obligated nor willing to participate in dispute resolution proceedings before a consumer arbitration body. Our preferred method of contact for issues is direct communication via email.
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).
For merchants, legal entities under public law, or public special funds, the exclusive place of jurisdiction for all disputes arising from or related to this contract is Munich.
Consumers as defined in Section 13 BGB may bring actions either at their general place of jurisdiction (customer's residence) or at the seat of the Provider in Munich.
Should any provision of these Terms be or become invalid, the validity of the remaining provisions is unaffected. Invalid provisions shall be replaced by valid provisions that achieve the economic purpose of the invalid provision.
The Provider reserves the right to modify these Terms with reasonable notice (minimum 6 weeks) via email. If the customer does not object within the notice period, the new Terms are deemed accepted. The right to object and the right to terminate remain unaffected.
