Terms of service

1. Scope and contracting parties

These terms apply to the use of the DomainWarn service (website and application) by businesses within the meaning of § 14 BGB, legal entities under public law and special funds under public law. The provider is Wigandt Technology, owner Johannes Wigandt, St. Georgenstr. 17, 56751 Polch, Germany. No offer is made to consumers; by registering, the customer confirms to act as a business. Deviating terms of the customer apply only if we expressly agree to them in text form.

2. Service

DomainWarn monitors the publicly accessible technical configuration of domains entered by the customer: availability and response time of the website (HTTP), TLS certificates, DNS records, mail servers (MX), SPF and DMARC records and registration data. The service detects changes and outages, manages them as incidents and notifies through the channels configured by the customer. Scope, number of domains, members and channels, check intervals and retention follow from the chosen plan as described on the pricing page.

We owe the provision of the service with the described functionality and serious efforts towards reliable and timely checks and notifications. We do not owe complete detection of every fault, delivery of every notification through third-party services or a specific reaction time. The free tools on the website are a non-binding service without any availability or accuracy commitment.

3. Registration and conclusion of contract

The contract for the free plan is concluded upon completion of registration. The contract for a paid plan is concluded when the customer selects a plan in the dashboard and completes the checkout with our payment provider Stripe. The customer is responsible for the accuracy of their details and the confidentiality of their credentials and must inform us immediately of any suspected unauthorised use.

4. Trial, prices and payment

Paid plans can be tested free of charge at first subscription for the period stated on the pricing page; without cancellation before the end of the trial the paid period begins. All prices are net plus statutory VAT; for customers in other EU countries with a valid VAT ID the reverse charge mechanism applies. Billing takes place in advance for the chosen billing period (monthly or yearly) via Stripe; invoices are provided electronically. A plan change during a billing period is prorated. In case of late payment we may restrict access after a reminder and terminate the contract after an unsuccessful grace period.

We may change prices with six weeks' notice effective from the start of a new billing period. If the customer does not object before the change takes effect, the new price applies; we point out the right to object and its consequences in the notice. If the customer objects, the contract ends at the end of the current billing period.

5. Term and termination

The free plan runs indefinitely and can be ended at any time by deleting the organisation. Paid plans run for the chosen billing period and renew automatically for the same period unless cancelled in the dashboard by the end of the current period. The plan remains active until the end of the paid period; afterwards the free plan with its limits applies. The right to extraordinary termination for cause remains unaffected.

6. Customer obligations

The customer may only enter domains they are authorised to monitor, in particular their own domains or domains of their clients with their consent. Notification targets (email addresses, webhooks, chat channels) must belong to the customer. The customer ensures that recipients of client reports agree to receive them. Prohibited are misuse of the service to probe third-party systems, automated bulk requests to the free tools, circumvention of limits and any use that impairs operation or violates the law. In case of violations we may block individual domains, channels or the account.

7. Availability and maintenance

We aim for an availability of the application of 99.5 % on a monthly average, measured by access to the application. Excluded are announced maintenance windows, disruptions outside our control (network operators, data centre, third-party services, force majeure) and periods caused by the customer. We announce maintenance at least 24 hours in advance in the dashboard or by email where possible.

8. Data protection and processing on behalf

We process personal data in accordance with our privacy policy. Where we process personal data on behalf of the customer as part of monitoring, the parties conclude a data processing agreement pursuant to Art. 28 GDPR, which we provide on request and which becomes part of this contract.

9. Changes to the service

We continuously develop DomainWarn and may change, add or discontinue features provided the core purpose of the service is preserved and the change is reasonable for the customer. We announce material restrictions at least four weeks in advance; in that case the customer may terminate as of the effective date.

10. Liability

We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the Product Liability Act and within the scope of a guarantee given. In case of slightly negligent breach of an essential contractual obligation (an obligation whose fulfilment is a prerequisite for proper performance of the contract and on whose observance the customer may regularly rely) liability is limited to the typical, foreseeable damage, but at most to the fees paid by the customer in the twelve months preceding the damaging event. Otherwise liability for slight negligence is excluded. In particular we are not liable for damage resulting from a fault not being detected or reported, or being detected or reported late or incorrectly, unless one of the above cases applies. The customer is responsible for backing up their own data and for appropriate security measures of their own.

11. Confidentiality

Both parties treat non-public information of the other party that becomes known to them in the course of the contract as confidential. We use the domains and data entered by the customer exclusively to provide the service and, in aggregated, non-attributable form, to improve the service.

12. Changes to these terms

We may change these terms with effect for the future where required due to changes in law, case law, market conditions or the service, and where this does not unreasonably disadvantage the customer. We announce changes at least six weeks before they take effect by email. If the customer does not object before the effective date, the changed terms are deemed accepted; we point out this consequence in the announcement.

13. Final provisions

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. Exclusive place of jurisdiction for all disputes arising from this contract is Koblenz, Germany, provided the customer is a merchant, a legal entity under public law or a special fund under public law. Should individual provisions be invalid, the validity of the remaining provisions remains unaffected. The contract language is German; this English version is for information only and in case of doubt the German version prevails.
