Terms of use

§ 1 Scope and contracting parties

(1) These terms govern the use of the service “eunormia” (the “Service”), operated by Michael Fellinger, Neuwiesenstraße 20, 8502 Lannach, Austria (the “Provider”).
(2) The Service is intended exclusively for entrepreneurs within the meaning of § 1 KSchG or § 1 UGB who use it in the course of their commercial or self-employed professional activity. Consumers are excluded from use. By using the Service, the user confirms that they are an entrepreneur.
(3) Conflicting terms of the user do not become part of the contract unless the Provider expressly agrees in writing.

§ 2 Description of services

(1) From invoice data provided by the user (JSON or CII-XML) and optionally a PDF file, the Service generates a structured electronic invoice in ZUGFeRD/Factur-X format (PDF/A-3) and checks the result technically against defined standards (including PDF/A validation and EN 16931 business rules).
(2) The Service performs a purely technical format and rule check. It does not verify the substantive, factual, tax or legal correctness of the invoice and does not replace tax or legal advice (see § 7).
(3) The embedded structured XML data set is always authoritative for the electronic invoice. Results generated without valid authentication carry a watermark and are not intended for production use.
(4) The Provider recalculates totals server-side and rejects invoices whose totals do not reconcile, rather than silently correcting them. This is a technical plausibility check and not a warranty of the correctness of the underlying values.

§ 3 Registration, account and credentials

(1) Certain functions require an account. The user must provide truthful information.
(2) The user keeps credentials and API tokens confidential and is responsible for all activity under their account. Any suspected misuse must be reported without delay.

§ 4 Fees; reservation of paid operation

(1) The Service is currently provided free of charge in test/beta operation. There is no entitlement to permanent free use.
(2) The Provider reserves the right to offer the Service or individual functions for a fee in future. A payment obligation arises only if the user expressly agrees to a paid plan. The Provider will give reasonable advance notice of changes.
(3) Usage quotas may be limited.

§ 5 Obligations and permitted use

(1) The user is solely responsible for the data they enter, its accuracy, completeness and legal admissibility, and for being entitled to process any personal data it contains.
(2) Prohibited in particular: unlawful use, circumvention of access or quota limits, automated overloading, reverse engineering beyond what is legally permitted, and uploading malicious content.
(3) The user remains the sole responsible issuer of their invoices vis-à-vis tax authorities and third parties.

§ 6 Availability, beta character, changes

(1) The Service is provided “as is” and without any guaranteed availability. The Provider owes no particular service level and no uninterrupted availability.
(2) The Service is under continuous development. The Provider may change, restrict or discontinue functions where reasonable for the user.
(3) Maintenance, faults and further development may lead to temporary restrictions.

§ 7 No tax/legal advice; no conformity guarantee

(1) Information on the website, in the blog, in the documentation and in messages of the Service is provided for general technical information and does not constitute legal, tax or other advice. It is provided without warranty as to accuracy, completeness or timeliness.
(2) The Provider does not guarantee that a generated invoice will be accepted by any particular recipient, system, portal or authority, or that it meets all tax/legal requirements in a given case. The technical validation relates solely to the standards and rules implemented at the time of generation.
(3) The user is responsible for verifying the suitability of the result for their specific use case and, where necessary, obtaining professional advice (tax adviser/lawyer).

§ 8 Warranty and liability

(1) As the Service is provided free of charge, the Provider is liable — to the extent permitted by law — only for intent and gross negligence. Any paid operation is governed by the terms then applicable.
(2) Otherwise, liability for slight negligence is excluded. The Provider is not liable for lost profit, indirect damage, consequential damage, loss of data, or damage arising from the non-acceptance or faulty further processing of generated invoices by third parties.
(3) Liability under the Product Liability Act and for personal injury, and for claims that cannot be excluded by law, remains unaffected.
(4) Where liability exists in principle, it is limited in amount to the foreseeable damage typical of the contract.
(5) The user indemnifies the Provider against third-party claims arising from the user’s unlawful or contract-breaching use of the Service.

§ 9 Rights to content

(1) Rights to the data entered by the user and the results generated remain with the user.
(2) All rights to the Service, software, trademarks and content of the Provider remain with the Provider or the respective rights holders. Third-party trademarks mentioned are used descriptively only.

§ 10 Data protection and processing

The processing of personal data is governed by the privacy policy. Where the Provider processes personal data on the user’s behalf in the course of invoice processing, the data processing agreement below (§ 14) applies additionally and forms part of the contract.

§ 11 Term and termination

(1) The usage relationship may be terminated by either party at any time without cause; by the user by deleting their account, by the Provider by blocking/deleting in the event of breaches or by discontinuing the Service with reasonable notice.
(2) As no invoice data is stored, no obligations to return or delete invoice content arise upon termination.

§ 12 Changes to the terms

The Provider may amend these terms with effect for the future and will notify users in an appropriate manner. If the user does not object within 14 days, or continues to use the Service, the amended terms are deemed accepted.

§ 13 Final provisions

(1) Austrian law applies, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods.
(2) The place of jurisdiction is — to the extent permitted — the court with subject-matter jurisdiction at the Provider’s seat.
(3) Should individual provisions be invalid, the remainder of the contract remains effective.

§ 14 Data processing agreement (DPA)

This DPA implements Art 28 GDPR for the processing of invoice content. The user is the controller, the Provider the processor.

Subject/purpose: processing of the personal data contained in invoice data (e.g. invoice recipients) for format conversion and validation.
Nature/duration: exclusively transient, in memory, for the duration of the respective request; no storage, no content logging; deletion occurs automatically when the request completes.
Instructions: processing only on instructions (the request constitutes the instruction).
Confidentiality & TOMs (Art 32): processing only in RAM/tmpfs, TLS transport encryption, no payload logging, access control, hardened hosting in the EU.
Sub-processors: netcup GmbH (hosting/infrastructure, DE/EU). The user consents to this sub-processor; changes will be notified (right to object).
Third countries: no transfer of invoice content to third countries.
Assistance & evidence: support with data-subject rights and notification duties and provision of necessary evidence, to the extent possible given the RAM-only processing.
Termination: as no content is stored, no separate return/deletion is required.
