These General Terms and Conditions apply to all services provided by QROVA (Miliienko Studio, Oleksandr Miliienko, Ober-Erler-Straße 34, 53547 Kasbach-Ohlenberg) via the website qrova.io.
QROVA offers a SaaS platform for creating, managing and analysing dynamic QR codes as well as for doing one's own bookkeeping and managing receipts. The available features depend on the selected plan (Free, Pro, Business, Agentur).
(1) The contract for the use of QROVA is concluded by registering on the platform and selecting a plan. For paid plans, the user submits a binding offer by clicking the correspondingly labelled button (“Order with obligation to pay” („Zahlungspflichtig bestellen“) or equivalent); the contract is concluded upon confirmation by the provider or upon successful completion of the payment process via Stripe.
(2) In the ordering process, the user states whether they are concluding the contract as a consumer (Verbraucher, § 13 BGB – German Civil Code) or as a business (Unternehmer, § 14 BGB). This information is decisive for the application of the statutory right of withdrawal (Widerrufsrecht) (Section 6). A statutory right of withdrawal exists exclusively for consumers.
(3) The provider stores the text of the contract and, after conclusion of the contract, sends the user a confirmation of the contract on a durable medium (email together with PDF) pursuant to § 312f BGB. The confirmation can additionally be accessed in the customer account under My contract documents.
(1) The prices shown on the website at the time of the order apply. QROVA is offered by the provider under the small-business scheme (Kleinunternehmerregelung) pursuant to § 19 of the German VAT Act (Umsatzsteuergesetz, UStG). Pursuant to § 19 UStG, no VAT is charged or shown; the prices stated are final prices.
(2) The Pro plan can be booked at a price of EUR 7 per month or EUR 67 per year, the Business plan at a price of EUR 10 per month or EUR 96 per year, and the Agentur plan at a price of EUR 19 per month or EUR 190 per year. The Free plan is free of charge.
(3) Payment is processed via the payment service provider Stripe (Stripe Payments Europe Ltd.). For this purpose, the user provides a valid means of payment. Depending on the selected billing period, the fee is collected monthly or annually in advance; the first debit takes place in accordance with Section 5 (free trial). For the annual plan, the full annual amount is collected with the first debit.
(4) When paying by SEPA direct debit, the user grants, in the payment process, a SEPA direct debit mandate in favour of Stripe Payments Europe Ltd., which carries out the collection on behalf of the provider. The period for advance notice (pre-notification) is shortened to one day before the collection. The user ensures that the account has the necessary funds. Costs incurred by the provider as a result of a returned direct debit (Rücklastschrift) for which the user is responsible may be charged by the provider in the actual amount; the user remains entitled to prove that the damage was lower.
(5) In addition, Stripe's general terms and conditions apply to the payment processing.
(1) Paid plans (Pro, Business, Agentur) begin with a free trial of 14 days from conclusion of the contract. No fee is charged during the trial. The free trial can be used once per customer and means of payment.
(2) The user is informed already when ordering that, after expiry of the 14-day trial, the subscription automatically converts into a paid subscription without any further declaration, unless it has been terminated or effectively withdrawn from beforehand.
(3) The first debit of the fee via Stripe takes place on the 15th day after conclusion of the contract (first day after expiry of the trial). If the user terminates or withdraws within the trial, no debit takes place.
(4) This trial arrangement does not affect the consumer's statutory right of withdrawal under Section 6; it does not replace it.
Consumers have the following statutory right of withdrawal. Businesses (§ 14 BGB) have no right of withdrawal.
Right of withdrawal. You have the right to withdraw from this contract within fourteen days without giving any reason. The withdrawal period is fourteen days from the day of the conclusion of the contract.
To exercise your right of withdrawal, you must inform us (Miliienko Studio, Oleksandr Miliienko, Ober-Erler-Straße 34, 53547 Kasbach-Ohlenberg, email: info@qrova.io) of your decision to withdraw from this contract by means of a clear statement (e.g. a letter sent by post or an email). You can also use the electronic withdrawal function on our website for this purpose. If you use this option, we will send you confirmation of receipt of such a withdrawal without delay (e.g. by email).
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal. If you withdraw from this contract, we shall reimburse to you all payments received from you without undue delay and at the latest within fourteen days from the day on which the notice of your withdrawal from this contract was received by us. We will carry out such reimbursement using the same means of payment as you used for the initial transaction, unless expressly agreed otherwise with you; in no event will you be charged any fees as a result of such reimbursement.
Note on withdrawal during the free trial: Since no payment is made during the 14-day trial, no reimbursement takes place in the event of a withdrawal within this period, because no payment has been made. You do not owe any compensation for value (Wertersatz) for the use during the trial (§ 357a(3) BGB).
(1) The Free plan runs for an indefinite period and can be ended at any time by deleting the account.
(2) Depending on the user's choice, paid subscriptions have a term of one month (monthly subscription) or one year (annual subscription) and are each extended by the same period unless they are terminated in due time. Consumer contracts can be terminated at any time after the initial term with a notice period of one month (§ 309 no. 9 BGB).
(3) Termination can take place at any time via the dashboard, the Stripe customer portal or the termination function on our website; for continuing obligations with consumers, the provider provides a termination button pursuant to § 312k BGB.
(4) The right of both parties to extraordinary termination for good cause remains unaffected.
(1) The user can change their plan at any time (upgrade or downgrade). A change to a higher-value or differently structured paid plan is deemed to be the conclusion of a new paid contract.
(2) With each such conclusion of a contract, a new 14-day withdrawal period under Section 6 begins for consumers, as well as, where applicable, a new billing period. Before the change is confirmed, the provider informs the user of the new price, the billing period and the renewed right of withdrawal.
(3) Fees already paid in advance for the previous plan are taken into account pro rata as part of the offsetting processed via Stripe.
We strive for an availability of 99%. Maintenance work is announced in advance where possible. No guarantee of uninterrupted availability is given.
We are liable without limitation in cases of intent and gross negligence. In cases of slight negligence, we are liable only for breach of essential contractual obligations, limited to the foreseeable damage typical of the contract. The details are governed by the section “Liability” below.
Details on data processing can be found in our privacy policy.
The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods (UN-Kaufrecht). If the user is a consumer with habitual residence in another state of the European Union, mandatory consumer protection provisions of that state remain unaffected (Art. 6 Rome I Regulation, Rom-I-VO).
The contract language is German. Only the German version of these General Terms and Conditions and of the other contract documents (data processing agreement (Auftragsverarbeitungsvertrag), information on the right of withdrawal) is authoritative. The user interface can be switched to English, Russian or Ukrainian; translations are for information purposes only and are not binding.
Should any provision of these General Terms and Conditions be invalid, the validity of the remaining provisions shall remain unaffected.
As of: 27 September 2026
(1) QROVA is software for doing one's own bookkeeping, for managing receipts and receipt data, and for creating and evaluating QR codes. QROVA provides the user exclusively with technical tools for recording, organising and evaluating their data on their own responsibility.
(2) QROVA provides no tax advice, no bookkeeping assistance with individual advice, no legal advice and no auditing. All notes, categorisations, posting suggestions, account assignments and evaluations provided by the software – including the AI features (e.g. “LISA”, receipt OCR) – are non-binding, automatically generated suggestions of a general nature and do not replace individual advice from a member of the tax-advisory or legal-advisory professions.
(3) The user bears sole responsibility for the substantive accuracy, completeness and admissibility under tax and commercial law of the recorded data and entries and of the evaluations created. The user is obliged to fulfil their tax and statutory obligations on their own responsibility and to check the results before use.
(4) The provider expressly recommends consulting a tax advisor (Steuerberater) or another person authorised to provide commercial assistance in tax matters for the final assessment of tax and legal matters and for the preparation of tax returns and annual financial statements.
(1) The provider is liable without limitation for damage resulting from injury to life, body or health that is based on an intentional or negligent breach of duty by the provider or by a legal representative or vicarious agent (Erfüllungsgehilfe) of the provider, as well as for damage based on intent or gross negligence on the part of the provider, its legal representatives or vicarious agents.
(2) The provider is furthermore liable without limitation insofar as it has guaranteed the presence of a characteristic (Beschaffenheit), and in accordance with the provisions of the Product Liability Act (Produkthaftungsgesetz).
(3) In the event of a slightly negligent breach of an essential contractual obligation (cardinal obligation, Kardinalpflicht), the fulfilment of which is a prerequisite for the proper performance of the contract in the first place and on compliance with which the user may regularly rely, the provider's liability is limited to the damage that is typical of the contract and foreseeable at the time the contract was concluded.
(4) Any further liability of the provider is excluded. In particular, the provider is not liable for slightly negligent breaches of obligations that are not essential contractual obligations (cardinal obligations).
(5) Insofar as the provider's liability is limited or excluded under the preceding paragraphs, this also applies to the personal liability of the provider's legal representatives, employees and vicarious agents.
(6) Insofar as liability exists in principle and is not unlimited under paragraphs 1 and 2, liability is limited in amount to the damage that is typical of the contract and foreseeable, but at most to the amount that the user paid to the provider as a fee for the use of QROVA in the twelve (12) months preceding the damaging event. In the case of free use (Free plan), liability in cases of simple negligence is limited to a maximum of EUR 50. The limitation of liability in amount does not apply in the cases of paragraphs 1 and 2.
(1) The user is responsible for regularly backing up their data stored in QROVA. For this purpose, the provider provides export functions in the formats PDF, CSV and DATEV.
(2) The user is obliged to create their own backup copies of their data via the export functions provided, at intervals reasonable for them, but at least before the end of the contractual relationship and before significant changes to their data stock.
(3) In the event of data loss, the provider is liable, in accordance with the above liability provisions, only for the effort that would have been required to restore the data even if the user had backed up the data properly and regularly. If the user fails to carry out the data backup that can reasonably be expected of them, they bear contributory fault (Mitverschulden) that reduces or excludes the claim (§ 254 BGB).
Insofar as the user processes personal data of third parties with QROVA (e.g. contact, customer or receipt data), the provider acts as a processor within the meaning of Art. 28 GDPR (DSGVO). For this, the separately concluded data processing agreement (Auftragsverarbeitungsvertrag, AVV) applies, which is accepted during onboarding.
