Terms of service

1. Scope

Your contracting party is Dmytro Yalanskyi. The full provider details, including the postal address, are in the legal notice.

These terms govern the use of the NormAPI services — the validation and generation API for electronic invoices, the website, and the partner account. The offering is directed exclusively at businesses (Unternehmer within the meaning of § 14 BGB); contracts with consumers are excluded.

Different or additional arrangements — on term, allowance, prices or availability, for example — can be agreed in an individual contract in text form. An individual contract takes precedence over these terms; where it is silent, these terms apply.

2. Service

NormAPI validates electronic invoices (XRechnung, ZUGFeRD) against the current official KoSIT ruleset and generates invoices in these formats from structured data. The ruleset version in force is stated in every API response. We track ruleset updates; their timing is at our discretion.

For paid plans we aim for API availability of 99.5% per calendar month; announced maintenance does not count. The status page shows the current state. The target does not give rise to credits; binding commitments can be agreed in an individual contract.

For free use there is no claim to availability, specific response times, or unchanged functionality.

3. Account and API keys

Any business can create an account itself; no invitation is required. API keys must be kept secret and not passed to third parties; the account holder is responsible for actions taken under a key. If compromise is suspected, a key can be revoked in the account at any time. We may suspend keys in cases of abuse or danger to the service.

4. Acceptable use

The published or individually agreed usage limits (rate limits, quotas) apply. Prohibited in particular: circumventing usage limits, submitting unlawful content, and reselling the service without a separate agreement.

5. Prices and payment

For paid plans, the prices on the pricing page or those agreed in an individual contract apply, net of VAT. Payment is processed by our payment provider Paddle acting as merchant of record, unless an individual contract provides otherwise; its terms additionally apply to the payment transaction. No fees are charged for free use; conditions promised to design partners remain unaffected.

6. Term and termination

Unless an individual contract provides for a different term, paid plans run monthly and can be cancelled at any time effective at the end of the current billing month. The right to extraordinary termination remains unaffected. Refunds are governed by the refund policy.

7. Data protection and processing on behalf

Where the customer has personal data processed through NormAPI — in invoices, for example — we process it on the customer's behalf. The data processing agreement in the version current at conclusion of the contract applies to this and forms part of this contract. The customer receives a signed copy on request. Other processing of personal data is described in the privacy policy.

8. No tax or legal advice

NormAPI is a technical tool. Validation results reflect the state of the machine-checkable ruleset and are no substitute for tax or legal advice. Responsibility for the content and lawfulness of issued invoices remains with the user.

9. Warranty and liability

We are liable without limitation for intent and gross negligence and for injury to life, body, or health. In cases of simple negligence we are liable only for the breach of essential contractual obligations (obligations whose fulfilment makes proper performance of the contract possible in the first place), limited to the foreseeable damage typical for this kind of contract. Liability for data loss is limited to the effort that would have been required had the user performed proper backups. For free use we are otherwise liable only for intent and gross negligence.

10. Changes to these terms

We announce changes to these terms in text form at least four weeks before they take effect. If the user does not object before the effective date, the changed terms apply; the announcement will separately point out this right to object and its consequences. In case of objection, either party may terminate effective on that date.

11. Final provisions

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If the customer is a merchant (Kaufmann), a legal entity under public law or a special fund under public law, the exclusive place of jurisdiction for all disputes arising from this contract is the customer's registered seat. The contract language is German. Should individual provisions be invalid, the remainder of the contract remains effective. Contact for all matters: kontakt@normapi.de.
