Effective Date: September 1, 2026
These Terms of Use (hereinafter: Terms) govern the use of the digital service OfficeZero (a graph-based knowledge base, document editor, and RAG-based conversational assistant; hereinafter: Service) at the website https://officezero.eu, as well as the conclusion of the contract between the Service Provider and the user of the Service (hereinafter: User).
2.1. The contract between the User and the Service Provider (hereinafter: Contract) is deemed concluded and a contractual relationship arises from the moment the User registers an account in the Service and confirms acceptance of these Terms.
2.2. The Contract is concluded for an indefinite period, unless otherwise provided in campaign conditions or special agreements.
2.3. If the User acts on behalf of a legal entity, they confirm that they hold all authority to bind said legal entity to the Contract.
2.4. The Service Provider reserves the right to unilaterally amend the Terms at any time. The User will be notified of amendments to the Terms via e-mail or within the Service environment at least 30 (thirty) calendar days before the changes take effect.
3.1. OfficeZero is a Software-as-a-Service (SaaS) platform providing the User with a graph-based knowledge base, document processing, and an artificial intelligence-based (RAG – Retrieval-Augmented Generation) query and conversational system.
3.2. The web application of the Service is responsive to screen size and suitable for use across various types of devices, ranging from modern smartphones and tablets to desktop computers.
3.3. The User acknowledges that on smaller screens, performing high-information-density tasks and operations (including using the document editor and graph analysis) may be inconvenient or functionally limited due to physical screen dimensions.
3.4. To ensure the best user experience and maximum utilization of screen space, it is recommended to install the web application directly onto your device (as an installable Progressive Web App / PWA), which removes control interfaces reserved by the browser.
3.5. A functioning internet connection and a modern, up-to-date web browser are required to use the Service. The Service Provider is not liable for interruptions or malfunctions resulting from the User's devices, outdated software, or internet connection failures.
4.1. Use of the Service is based on an internal account billing system. The User can add funds to their account ("Add funds") via payment methods offered on the platform (bank link, payment card, etc.). The top-up amount is freely chosen by the User, but may be subject to a minimum transaction amount of EUR 10 to cover transaction processing costs.
4.2. Upon selecting or changing a Service plan, the periodic cost of the chosen plan is fixed. A corresponding amount equal to the cost of the selected plan is reserved (held) from the User's account balance. The reserved amount guarantees Service availability for the respective billing period.
4.3. The User has the right to change or cancel their plan at any time. Upon changing or cancelling a plan, the system automatically calculates a pro-rata settlement for the days actually used, for which a final invoice is issued and debited from the reserved amount. Any remaining reserved funds beyond actual usage are immediately released from the reservation. Upon changing a plan, funds are reserved in the amount of the new plan. Amounts released from reservations remain in the User's account balance.
4.4. If the User consumes additional volume-based services beyond the plan, their cost will be deducted from the User's available account balance or reserved according to the rules of the service.
4.5. Provision of the Service and availability of functionalities are guaranteed provided that the User's account balance (considering the ratio of available and reserved funds to actual invoices) is not negative. If the available account balance is exhausted and reservations do not cover the service volume, the Service Provider has the right to restrict access to the Service until the balance is topped up.
4.6. Refund of unused available funds is carried out in accordance with Section 11.3 of these Terms.
4.7. For every deposit made to the account and for each period of actually provided service/plan, the system automatically generates a compliant invoice or payment confirmation, which is made available to the User on the platform and/or sent by e-mail.
5.1. A consumer who is a natural person has a legal right to withdraw from a contract concluded online within 14 days.
5.2. By agreeing to these Terms and launching the use of the Service (or making a payment), the User gives explicit prior consent for the immediate commencement of the provision of the digital service before the expiration of the 14-day withdrawal period.
5.3. The User acknowledges and confirms that they lose their 14-day right of withdrawal from the moment access to the Service is granted and provision of the service has commenced.

7.4. In any event, the total aggregate financial liability of the Service Provider to the User is limited to the amount actually paid by the User to the Service Provider during the three (3) months immediately preceding the occurrence of the damage.
7.5. The Service is primarily designed and adapted for the legal framework and market needs of the European Union.
