Legal notice (Impressum)

This is a courtesy translation. The German version of this legal notice is the legally binding one; in case of any discrepancy between the German and the English version, the German version prevails.

1 · Provider

Information pursuant to § 5 of the Digitale-Dienste-Gesetz (DDG — the German act on digital services implementing the provider-information duties of the e-Commerce Directive; not the EU Digital Services Act).

• Provider (Anbieter within the meaning of § 5 DDG): Oliver Wagener
• Address: Ahnekamp 41, 31137 Hildesheim, Deutschland

The provider operates this service as a natural person. There is no entry in a register; the information under § 5 (1) no. 4 DDG (register and registration number) therefore does not apply. No VAT identification number (USt-IdNr.) and no Wirtschafts-Identifikationsnummer (business identification number under § 139c AO, the German Fiscal Code) have been issued; § 5 (1) no. 6 DDG requires this information only "if available".

The address given is the provider's ladungsfähige Anschrift (an address at which legal process can be served); it is not a P.O. box.

2 · Person responsible for the content pursuant to § 18 (2) MStV

The person responsible is Oliver Wagener; the address is the one given under § 1. (MStV: Medienstaatsvertrag — the German Interstate Media Treaty.) (MStV: Medienstaatsvertrag — the German Interstate Media Treaty.)

3 · Contact and how to reach us

• Contact form: zirko.io/gb/contact — the same page exists in every market area in the language of that market, reachable from the footer area of the website
• General inquiries: info@zirko.io
• Support with using the software: support@zirko.io
• Data protection and data subject rights: datenschutz@zirko.io — for the data we ourselves are responsible for: this website, your user account, contract and billing

If your data is in Zirko because a business entered it there, that business is the controller — not we. That applies to everything a craft business keeps in its own area: customers and orders just as much as the working times and wages of its employees. Access to, rectification of or erasure of such data is therefore something you request from your business. If such a request reaches us nonetheless, we do not answer it ourselves: we forward it to the business without undue delay and inform you that we are not the controller (Art. 28 (3) (e) GDPR, § 9 (4) of the Auftragsverarbeitungsvertrag (data processing agreement)). Which data we are responsible for ourselves and which the business is responsible for is set out in the Datenschutzerklärung (privacy policy).

A means of direct communication within the meaning of § 5 (1) no. 2 DDG is available through the email addresses named above and through the contact form. We do not publish a telephone number; it is not among the mandatory information (Court of Justice of the European Union, judgment of 16 October 2008, Case C-298/07).

We reply in German and in English. We do not commit to any response time (§ 6 (5) of the Allgemeine Geschäftsbedingungen (General Terms and Conditions)).

Anyone who has reached us by one of these routes and who afterwards no longer has access to the internet will be given a non-electronic means of communication on request.

What you can expressly request here

Two claims under the Terms are not triggered in the application but requested here. Both are free of charge, and both need no more than text form (Textform within the meaning of § 126b BGB — a legible declaration on a durable medium naming the declaring person; no signature is required) — an email to info@zirko.io is enough.

• Extension of the export period (§ 12 (4) (a) of the Terms). After the end of the contract, access remains in place in read-only form for 30 days. If that time is not enough, we will extend it on request once by 30 days. The request must be received by us before the first period expires.
• Provision of the data by another route (§ 12 (4) (a) of the Terms). If the export in the application is not sufficient in an individual case, we will make the data available by another route on request within 14 days. There is no claim to a particular file format or to a single complete download.

4 · Regulatory authority, professional title, official authorization

The provider makes software available. This activity requires no official authorization; the information under § 5 (1) no. 3 DDG (the competent regulatory authority for activities requiring official authorization) therefore does not apply.

The provider does not practice a regulated profession. The information under § 5 (1) no. 5 DDG (chamber, statutory professional title, rules of professional conduct) likewise does not apply.

The provider does not provide legal, tax or bookkeeping advice. The software supports the creation of accounting documents (Belege) and the recording of data; the assessment for tax and bookkeeping purposes remains with the Customer and their adviser (§ 7 of the Terms).

The supervisory authority responsible for data protection is named in the Datenschutzerklärung (privacy policy); it also states how the right to lodge a complaint under Art. 77 DSGVO (GDPR) is exercised.

5 · Dispute resolution

Zirko is aimed exclusively at Unternehmer (entrepreneurs within the meaning of § 14 BGB — any natural or legal person acting in the exercise of their trade, business or profession) and not at Verbraucher (consumers within the meaning of § 13 BGB); the Terms exclude the formation of a contract with consumers (§ 1 (2) of the Terms).

The European Online Dispute Resolution platform (ODR platform) was shut down on 20 July 2025.

We are neither obliged nor willing to take part in dispute resolution proceedings before a Verbraucherschlichtungsstelle (consumer dispute resolution entity) (§ 36 VSBG — the German Act on Consumer Dispute Resolution).

6 · Liability for our own content, for the content of the businesses and for links

As a service provider (Diensteanbieter, §§ 7 to 10 DDG) we are responsible under § 7 (1) DDG for our own content on these pages in accordance with general law. Under §§ 8 to 10 DDG, however, we as a service provider are not obliged to monitor third-party information that we transmit or store, or to investigate circumstances that indicate unlawful activity. Obligations to remove information or to block its use under general law remain unaffected; liability in this respect is, however, only possible from the point in time at which knowledge of a specific infringement of the law is obtained. If we become aware of an infringement of the law in content of our own, we will remove that content immediately. Our own content is what we publish ourselves: the pages of this website, our help texts and our articles.

What a business creates in Zirko is not our content. Orders, quotes, invoices, customer and employee data belong to the business that entered them; it alone is responsible for them. We do not monitor them and do not check their content. Nor do we remove them of our own accord — for two reasons: we process them exclusively on the instruction of the business (Art. 28 (3) (a) GDPR, § 3 of the data processing agreement), and an issued document must be retained under the tax law of its country and remains unchangeable — it is corrected by a Storno, a cancellation document posted alongside it, and not deleted (§ 6 of the data processing agreement). Anyone objecting to content that a business has stored in Zirko therefore turns to that business. If such an objection nonetheless reaches us, we forward it to that business without undue delay and tell the sender that we are not the controller. What an official or judicial order requires of us remains unaffected.

Our online offering contains links to external third-party websites over whose content we have no influence. We cannot accept any liability for this third-party content; responsibility always lies with the respective provider or operator of those pages. The linked pages were checked for possible legal infringements at the time the links were created; unlawful content was not discernible. Permanent monitoring of the content of linked pages without concrete indications of an infringement of the law cannot reasonably be expected. If we become aware of infringements, we will remove such links immediately.

7 · Copyright

The content and works created by us on these pages are subject to German copyright law. Contributions by third parties are marked as such.

The software used in Zirko employs open-source components; their license terms remain unaffected. We provide an overview on request at info@zirko.io.

8 · Customers outside Germany

Zirko is offered in twenty-three countries. The following applies to the information in this legal notice:

• European Economic Area (Austria, the Netherlands, Luxembourg, Ireland, the Czech Republic, Sweden, Finland, Estonia, Latvia, Lithuania, Malta, Cyprus, Italy, Poland, Romania): The country-of-origin principle under Art. 3 of Directive 2000/31/EC applies, implemented in Germany in § 3 DDG. The obligations that govern are therefore those of a German provider, and they are fulfilled above.
• Switzerland: Art. 3 (1) (s) UWG (Bundesgesetz gegen den unlauteren Wettbewerb — the Swiss Federal Act against Unfair Competition) requires providers in electronic commerce to state clearly their identity and a contact address including an email address. § 1 and § 3 do this.
• United Kingdom: Regulation 6 of the Electronic Commerce (EC Directive) Regulations 2002 requires the name, a geographic address and an electronic contact detail; register and VAT information only to the extent that an entry in a register exists or a VAT liability applies. § 1 and § 3 do this.
• United States, Canada, Australia, New Zealand: There is no general obligation to publish a legal notice there. We fulfill the obligation to identify the sender in commercial emails (CAN-SPAM, CASL, Spam Act 2003) in those emails themselves, not through this page.
• Japan: The Japanese counterpart to a legal notice is not a general provider identification but an advertising duty in distance selling: Art. 11 of the Act on Specified Commercial Transactions (特定商取引に関する法律, Act No. 57 of 1976) requires certain particulars in advertising for 通信販売, among them — under Art. 11 no. 6 in conjunction with § 23 no. 1 of the enforcement ordinance (特定商取引に関する法律施行規則) — name, address and telephone number. These provisions do not apply to our contract: Art. 26 (1) no. 1 of the same Act exempts contracts which the purchaser enters into for the purposes of their business or in the course of a business, and Zirko enters into contracts exclusively with Unternehmer (entrepreneurs; § 1 (2) of the Terms). We state our name, address and electronic means of contact nonetheless — they are in § 1 and § 3; and we do not publish a telephone number here either. A separate matter is the identification of commercial email: Art. 4 of the Act on Regulation of Transmission of Specified Electronic Mail (特定電子メールの送信の適正化等に関する法律, Act No. 26 of 2002) requires every advertising email to display the sender's name and an address at which the recipient can object to further messages. We fulfill that duty — as in the four countries named above — in the emails concerned themselves, not through this page.

Which functions are available in which country is governed by § 9 of the Terms; the invoicing module is not available in all countries.
