Terms and Conditions

Last updated: 30 May 2026

These terms apply between Dachs Consulting GmbH and the customer using the hosted Sendity service, unless a separate written agreement says otherwise.

Provider

Sendity is provided by Dachs Consulting GmbH, Mierendorffweg 8, 64572 Büttelborn, Germany.

Service

Sendity provides channel-control authentication workflows. It creates short-lived authentication challenges, verifies matching messages from a channel the user controls and returns a verification result to the customer application.

Email verification is available today. Additional channels require explicit agreement before use.

Customer responsibilities

The customer remains responsible for its users, accounts, permissions, roles and authorization decisions.

• The customer must configure allowed origins, public app identifiers and verification destinations correctly.
• The customer must verify Sendity results server-side before creating or elevating an application session.
• The customer must not use Sendity for unlawful, abusive, deceptive or high-risk use cases without a suitable separate agreement and risk assessment.
• The customer is responsible for informing its own users about the customer’s use of Sendity.

Data protection

The hosted Sendity service is operated in a GDPR-compliant setup on Hetzner infrastructure in Nuremberg, Germany.

A separate data processing agreement under Art. 28 GDPR is required for production use of the hosted service. This applies where Dachs Consulting GmbH processes personal data on behalf of the customer.

Availability and changes

Dachs Consulting GmbH uses reasonable technical and organizational measures to operate Sendity securely and reliably. Specific availability commitments, support response times, service credits or dedicated operational requirements apply only if agreed separately in writing.

Dachs Consulting GmbH may update the hosted service to maintain security, compatibility, performance or legal compliance. Material changes that require customer action will be communicated with reasonable notice where practical.

Acceptable use

The customer must not misuse Sendity, attack or overload the service, attempt to bypass security controls, process unlawful content, infringe third-party rights or use Sendity in a way that harms the service, Dachs Consulting GmbH or other customers.

Open-source components

Sendity may provide open-source client libraries, adapters or reference implementations. Those components are licensed under their respective open-source licenses. The hosted Sendity service remains subject to these terms or the applicable customer agreement.

Liability

Dachs Consulting GmbH is liable without limitation for intent, gross negligence, injury to life, body or health and under mandatory statutory liability. For slight negligence, liability is limited to breaches of essential contractual obligations and to the foreseeable, typical damage, unless mandatory law provides otherwise.

Term and termination

Either party may stop using or providing non-paid evaluation access at any time. Production subscriptions, paid plans, notice periods, export obligations and deletion commitments are governed by the applicable order form, data processing agreement or separate written contract.

Governing law

German law applies, excluding conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. If the customer is a merchant, legal entity under public law or special fund under public law, the courts competent for the registered office of Dachs Consulting GmbH have jurisdiction unless mandatory law provides otherwise.
