1. Scope and relationship to Wilken Terms

These supplementary terms (“StayBooking Terms”) apply to the purchase, licensing, and use of the StayBooking WordPress plugin and related online services (checkout, license server, customer area/dashboard) of Wilken UG (haftungsbeschränkt), Braugasse 14C, 50859 Cologne, Germany (“Wilken”, “we”).

The general Terms and Conditions of Wilken UG (haftungsbeschränkt) (“Wilken Terms”) also apply. StayBooking is an add-on product. The StayBooking Terms cover product-specific matters; otherwise and for gaps, the Wilken Terms apply. If there is a conflict on StayBooking-specific questions, the StayBooking Terms prevail.

Other brands or products of Wilken UG (haftungsbeschränkt), including VirtusNova and Inclusio, remain governed by their own published or individually agreed terms and are not replaced by these StayBooking Terms.

2. Contracting party and B2B only

The contracting party is exclusively Wilken UG (haftungsbeschränkt). StayBooking is offered only to entrepreneurs within the meaning of Section 14 of the German Civil Code (BGB). Consumers within the meaning of Section 13 BGB are excluded. By ordering or completing checkout, you confirm that you are an entrepreneur acting in the course of your trade, business, or profession.

If you accept these terms on behalf of a company or other legal entity, you represent that you have authority to bind that entity.

3. Subject matter and services

StayBooking is a WordPress plugin for direct booking and management of hotel or lodging offers on your own website. What is owed is the feature package named at checkout or in the order confirmation, in the version installed at delivery. If neither names a package, the scope follows the product description on wilken.solutions at the time of order.

The recurring fee buys the right to keep using that version on the licensed website, plus efforts to fix defects in the purchased functions. Those efforts are not a promise of a particular result, do not reduce the price, and do not create a right to cancel because of a defect.

New modules, product improvements, and customer wishes are not owed. Wilken may ship updates when Wilken decides to. No date and no particular content is owed. Suggestions and feature requests are not an order and create no claim. If Wilken builds on a suggestion, the rights stay with Wilken. The function may be offered to other customers. The suggesting customer acquires no exclusive right in it and no right to have it enabled, unless it is already part of that customer’s purchased package.

Live support, a promised response time, remote maintenance, training, and setup are not included unless ordered separately.

Hosting, domain, backups, availability, and operation of your website are not part of this license. StayBooking runs on your infrastructure. Website creation, photography, and a PMS connection are not part of this license. Proposals, conversations, and other materials expand the scope only when they are expressly named in the order confirmation or at checkout.

A partial package enables only part of the software, including by feature flags. You have no right to disabled areas and no right to the behaviour of the full product. Faults that arise because modules are missing or only part of the software is active are not a defect. They do not require Wilken to enable the missing modules and they do not create a claim for damages. If a function that is itself in the purchased package fails, only the duty to try to fix it applies.

StayBooking is not warranted as a system already proven in production with your guest data. The duty to pay exists whether or not you actually use the software.

During an individually agreed minimum term, purchased feature flags are not withdrawn except for security or legal reasons. New modules remain not owed. The price agreed for the minimum term applies for that term. For a renewal, Wilken may adjust the price with the cancellation notice that applies to that renewal.

In the customer area on wilken.solutions you can buy, manage, and cancel licenses, open installation guides, and view billing information. A request does not create a support entitlement. Access is via magic link and/or an optional password.

You do not acquire ownership of the plugin or source-code rights beyond the license granted here. Services not expressly described (e.g. individual PMS integrations, accounting advice, tax advice, website design, hosting of your WordPress installation, operation of your booking database) are not owed.

4. Self-hosting, data responsibility, and no guest data storage at Wilken

StayBooking runs on your own WordPress installation (“self-hosting”). Booking, guest, payment, and other operational data collected or processed via StayBooking on your website is generally stored in your WordPress database and on your infrastructure. Wilken does not centrally store, host, or process such guest and booking data for your business purposes.

You are solely responsible as data controller for processing personal data of your guests and other end users in connection with StayBooking on your website. Wilken processes personal data in connection with StayBooking only to the extent required for licensing, checkout, contract performance, and operation of wilken.solutions (see the StayBooking Privacy Policy).

To activate and periodically validate a license, your WordPress installation may contact Wilken’s StayBooking license server. Only license-related technical data is transmitted (e.g. license key, domain, validation result), not your guest or booking records.

5. No guarantee of occupancy, revenue, PMS compatibility, or tax correctness

StayBooking is a technical tool for booking on your website. Wilken does not warrant any particular occupancy rate, minimum number of bookings, revenue, profit, or commercial success of your lodging business.

A PMS connection is not owed. Wilken does not owe error-free transfer to a property management system and is not liable for double bookings or lost reservations. The same applies to channel managers and other third-party software. Integrations, interfaces, or exports may be limited, changed, or discontinued.

Wilken does not compensate lost bookings, lost occupancy, cancellations, overbookings, claims by your guests, or portal commissions you pay instead.

Pricing, tax, VAT, and levy logic in the plugin supports your configuration. Wilken does not warrant the tax, accounting, or legal correctness of prices, tax rates, levies, or invoice content. You remain solely responsible for the correct tax and legal design of your offer.

Communications with Wilken are not legal, tax, or accounting advice.

6. Defect notice, fixes, and your website

The period for defects in purchased functions is 30 days and starts with the first Stripe invoice for that license. Staging or another preview environment does not start the period and does not use it up. During the period you may report defects in purchased functions in text form. The report names the function, the time, and the steps. Wilken will try to fix it. After the period, the delivered version is accepted.

During those 30 days and afterwards there is no claim for compensation for revenue, data loss, or outage. An agreed minimum term and the duty to pay remain. Without your cooperation and without your own test bookings during the 30 days, the duty to try a fix is suspended.

You back up your WordPress installation before installing StayBooking and before every update. Wilken does not centrally store booking or guest data, does not create backups, and does not owe restoration.

No availability of your website, no service level, and no particular response time is owed. An outage of hosting, WordPress, email, a payment service, Stripe, or the license server is not a defect in the license.

WordPress, PHP, your theme, other plugins, email delivery, and a payment service you connect are yours. Changes to them, and failed guest emails or payments, are not a defect. Wilken is not a payment institution.

You keep a reservation path that does not depend on StayBooking.

7. License

The subscription grants a limited, non-exclusive, non-transferable, non-sublicensable license to use StayBooking on the licensed apex domain (label domain from checkout) while the subscription remains active and these terms are complied with.

One license covers one apex domain (e.g. example.com); subdomains of the same apex domain (e.g. www.example.com, booking.example.com) are generally covered unless expressly agreed otherwise. Simultaneous use on multiple apex domains requires separate licenses. Resale, rental, service-bureau use, or making StayBooking available to third parties without Wilken’s consent is prohibited. Sharing installation information with contractors (e.g. agencies) to set up StayBooking on your licensed domain is permitted.

Multiple licenses may be managed under one customer account; each license may be linked to its own Stripe subscription. Reverse engineering is permitted only to the extent mandatory law requires.

8. Contract formation, subscription, payment, and cancellation

The contract is formed when online checkout (including payment authorization) succeeds and the license(s) are activated. Prices are net plus applicable taxes (including automatic calculation via Stripe Tax where enabled). You must provide accurate billing and, where applicable, VAT ID details at checkout.

Service providers, agencies, and other representatives may purchase on behalf of an end client (“purchase on behalf”). In that case, the invoice recipient named on the invoice is the contractual party for billing and payment; the login email is used for technical license management. The person completing checkout declares their authority to act.

Each license is typically billed as its own subscription (monthly or yearly) and renews automatically for the selected interval unless cancelled in time. You may add further licenses in the customer area; then the prices shown at the time of the add-on order apply. Checkout authorises the charges described there, including later renewals at the agreed interval, for as long as the contract continues.

In the customer area you can buy and manage licenses and declare cancellation (Cancel subscription). A cancellation is effective only if it is declared in the customer area and also confirmed by email to info@wilken.solutions. The customer area alone or the email alone is not enough. Both must arrive within the deadline.

Unless a separate contract sets another deadline: for a yearly subscription, cancellation must arrive at least one month before the end of the current yearly period and takes effect at the end of that period. If it arrives later, the subscription renews for another year. For a monthly subscription, cancellation must arrive by the 15th of a month and takes effect at the end of the current billing period. If it arrives after the 15th, it takes effect only at the end of the following billing period.

A separately concluded contract, in particular one with a longer minimum term, keeps its own cancellation deadline. The customer area and the email are still both required. During a minimum term the customer area does not end the contract early. An individual minimum term and package limit in an order confirmation prevail over these standard deadlines.

After an effective cancellation, access continues until the cancellation takes effect. The right to use then ends. Prepaid periods are generally non-refundable except where mandatory law requires otherwise.

Invoices and payment methods can be managed in the customer area and/or via the Stripe customer portal. Payments are processed via Stripe.

9. Suspension and deactivation of the license

Wilken may suspend or permanently deactivate access to the customer area, license validation, and/or plugin updates at any time, in particular for non-payment, failed charges, chargebacks, breach of these terms, abusive use, unauthorized multi-domain use on unlicensed domains, or where Wilken is legally required to suspend access.

Suspension or deactivation does not affect your sole responsibility for booking and guest data stored on your WordPress installation. Wilken does not create backups of such data and cannot restore your operational data upon suspension.

10. Privacy

Processing of personal data in connection with purchasing and licensing StayBooking is described in the StayBooking Privacy Policy and, additionally, the Wilken UG Privacy Policy. See the StayBooking Subprocessor List for processors used.

We store license data (license key, domain, plugin version, validation result, and related contract data) with a processor in Frankfurt (EU).

For guest and booking data on your website, you are the controller and must inform your guests accordingly.

11. Warranty and liability

To the extent permitted by law, StayBooking is provided “as is” and “as available”. Wilken does not warrant uninterrupted or error-free operation, security against third-party attacks, or fitness for your particular business purposes. Faults that come from a partial package or from disabled feature flags are not a defect. An outage of your website, your hosting, or the license server is not a defect and is not a promised availability.

Wilken is liable without limitation for intent and gross negligence and for injury to life, body, or health. For slight negligence, Wilken is liable only for breach of material contractual duties (cardinal duties), limited to typical foreseeable damage.

To the extent permitted by law, Wilken’s aggregate liability arising out of or relating to StayBooking is limited to the net fees you paid for the affected StayBooking services in the twelve (12) months preceding the event giving rise to the claim.

To the extent permitted by law, Wilken is not liable for unauthorized access, hacking, malware, security incidents, data loss, data corruption, or outages on or relating to your WordPress installation, hosting, database, backups, or StayBooking configuration. Wilken does not create backups of your booking or guest data and does not owe their restoration.

Liability for indirect damages, lost profits, lost bookings, lost occupancy, business interruption, or claims by your guests or third parties relating to your booking or privacy practices is excluded except for intent, gross negligence, or mandatory liability.

The above limitations do not apply where the German Product Liability Act or other mandatory rules provide otherwise.

12. Customer obligations

You provide accurate company, billing, and contact details, email address(es), and domain labels and keep customer-area and WordPress credentials confidential. You use StayBooking lawfully and will indemnify Wilken against third-party claims arising from your website, booking processes, content, guest data processing, or use of StayBooking, except to the extent caused by Wilken’s intent or gross negligence.

You are solely responsible for the security, availability, maintenance, and regular backup of your WordPress installation, database, and all booking and guest data processed via StayBooking. You back up before installing StayBooking and before every update. You implement appropriate technical and organizational measures (e.g. updates, backups, access controls, SSL/TLS).

If you want to use the 30-day period after the first Stripe invoice, you run your own test bookings and describe defects with the function, the time, and the steps. You keep a reservation path that does not depend on StayBooking.

You obtain all required consents, notices, and legal bases for processing personal data of your guests and ensure a privacy-compliant booking flow. If you share access information with third parties (e.g. agencies), you remain responsible for their lawful use within your license.

13. Changes and governing law

Wilken may amend these StayBooking Terms for the future, especially for legal, case-law, or product reasons. Material changes will be communicated appropriately (e.g. email or website notice). Objection and continuance rules in the Wilken Terms apply correspondingly where relevant.

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. Venue for merchants is Cologne where permitted. Mandatory protective rules of your place of business remain unaffected to the extent they apply to entrepreneurs.

Visibility

The homepage is enough. We pull the important inner pages ourselves.

Where should the report go?

We send the one-time code and the report link by WhatsApp. Email stays available as a second path.

One last step, then we start

After this you get a short WhatsApp code. The check starts only then. The link arrives by WhatsApp and email, not on this page.

Your check is running

This usually takes 2 to 5 minutes. We send the link by WhatsApp and email, not on this page.

Almost there

Confirm, then we start the report

We sent a six-digit code to your WhatsApp. Enter it here and the check begins. Email stays available as a second path.

Where should a copy go?

WhatsApp is the first path. Email is the backup if the chat does not arrive.

Two checks are enough for now

We already have a clear picture. The useful next step is a 30-minute video call with Tim, not another document.
