Official effective date: 5 November 2025  

Email: help.app.yb@gmail.com 

1. Introduction  

These Terms of Use (hereinafter – the “Terms”) are drawn up by the developers of the mobile application Opora (hereinafter – the “Application”, the “Mobile Application”, “we”, the “Developer”).  

The terms in these Terms:  

“AI assistant” means an automated service for responding to user queries, implemented locally or with the involvement of external providers;  

“Premium features” means functionality available only by subscription (for example: AI assistant, enhanced search, etc.).  

By installing or using the Opora Application, you agree to comply with these Terms. If you do not agree with the Terms, do not install and do not use the Application.  

2. Description of the Service  

The Application provides users with access to a catalog of legal documents of Ukraine (in particular: the Constitution, administrative and criminal codes, resolutions, ministerial orders, traffic rules and other acts) taken from open official state sources, together with such functions as intelligent semantic search, AI assistant and other premium features.  

We provide services and do not sell legal documents or provide legal consultation.  

3. Use of the AI assistant  

The AI assistant function provides automatic answers to your queries in order to help the user navigate the documents.  

You acknowledge and agree that:  

•  the Application and the AI assistant are not a legal adviser, do not provide individual legal assistance and their answers do not have legal force;  

•  the Application and the AI assistant may provide inaccurate, incomplete or outdated information. You are solely responsible for verifying the information through official sources or with a qualified specialist;  

•  the service is provided “as is” and “as available”. We are not liable for any decisions, consequences or damages that may arise as a result of the use of the Application or the AI assistant;  

•  the use of the Application and the AI assistant is at your own risk. Communication with the AI assistant or support service does not create an attorney-client relationship and does not establish confidentiality as in legal practice;  

•  it is prohibited to use the answers of the AI assistant as a basis for drafting claims, applications, complaints, official documents or other materials of a legal nature that may affect your rights or obligations;  

•  AI responses may contain fabricated or incorrect statements (hallucinations). The user independently verifies the information.  

We do not guarantee that the answers of the AI assistant will be accurate, relevant or correspond to the latest changes in legislation.  

You agree that any advice, texts or links generated by AI are used by you solely at your own discretion.  

You warrant that you have legal grounds to send any texts or materials to the AI assistant and that such materials do not violate the rights of third parties.  

In addition, you agree that:  

•  the results of the AI may contain errors, contradictory conclusions or biases;  

•  the Developer does not carry out an independent verification of the facts and information generated by the AI;  

•  AI models may be improved on the basis of aggregated user data;  

•  in case of doubt you must refer to official sources or a qualified specialist.  

For the technical improvement of the operation of local search and optimization of interaction with the Application, text queries may be sent anonymously and in aggregate to an external analytical service (in particular Mixpanel). The data are not used to identify the user or for marketing purposes.  

We do not store your queries to the AI on our own servers for the purposes of model training. External AI providers (for example, OpenAI, Google or others) may store and use the queries sent to them to improve their services or train models in accordance with their own policies.  

You agree that the use of external AI providers is subject to the policies of these providers and not exclusively to our Privacy Policy. You also agree that the external AI provider may be changed without prior notice to the user of the Application.  

4. Use of local search by documents  

The functionality of local search by documents is provided for processing text queries without transferring data to external AI providers and for the purpose of facilitating navigation and work with the documents.  

The user acknowledges and agrees as follows:  

•  all user text queries are processed locally on the user’s device. No queries are transmitted to external artificial intelligence services for the formation of responses or training of models;  

•  for the technical improvement of the operation of local search and optimization of interaction with the Application, text queries may be sent anonymously and in aggregate to an external analytical service (in particular Mixpanel). The data are not used to identify the user or for marketing purposes;  

•  the use of local search is at the user’s own risk. The Developer is not liable for inaccuracies, errors or incomplete information obtained as a result of the search;  

•  we recommend that you do not send personal data, sensitive information or other materials that should not be processed by external services, even for analytics.  

5. Subscriptions and payments  

The Application uses a subscription model for premium features. Subscriptions are made through Google Play Billing and are managed via Apphud.  

Payment of the relevant fees grants you access to the premium features for the selected period.  

Subscriptions are automatically renewed unless cancelled through Google Play settings before the renewal date.  

You are responsible for all charges associated with your account.  

Refunds are carried out in accordance with the Google Play rules; we do not issue refunds ourselves.  

The Developer reserves the right to change prices, lists of features in tariffs or discontinue the provision of certain premium features. Changes do not affect already active subscriptions until their term expires.  

6. Intellectual property  

All legal documents provided in the Application are public state sources and are not our exclusive property.  

We own and reserve all rights to the code, design, index base, interface and other components of the Application. Copying, modification, distribution or public display of such components without our written consent is prohibited.  

The user is granted a limited, non-exclusive, non-transferable license to use the Application in accordance with these Terms. It is prohibited to temporarily or permanently perform actions that restore or reproduce the internal structure, code or databases of the Application.  

7. Advertising  

In the free version of the Application, advertising may be displayed. You understand and agree that third-party advertising networks may collect data on usage and device identifiers for the personalization of advertising. 

If you have an active premium subscription, the App may operate without ads.

8. User obligations  

You agree not to:  

•  use the Application for unlawful purposes or violate these Terms;

The user is responsible for the materials that they send in queries to the AI (including text, contacts, documents). The user warrants that they do not send materials that violate the rights of third parties or contain harmful elements.  

9. Disclaimer  

The Opora Application is not a legal consultation and does not replace professional legal assistance.  

The AI assistant may provide answers of an analytical or reference nature; however, they should not be perceived as official advice or recommendation.  

We do not guarantee the accuracy, relevance or completeness of the information obtained through the AI assistant or when using any functions of the Application.  

The user assumes full responsibility for any decisions or actions taken on the basis of the information received.  

Updates of legal acts may occur with a delay; we do not guarantee that the document in the Application is the latest valid version.  

No information provided through the Application or the AI assistant may be regarded as official legal, medical or financial advice.  

10. Limitation of liability  

To the maximum extent permitted by applicable law:  

•  the Application is provided “as is”, “as available”, without any warranties, express or implied;  

•  we disclaim all warranties, including warranties of merchantability, fitness for a particular purpose, accuracy or reliability of information;  

•  in no event shall we be liable for any indirect, incidental, special or consequential damages arising out of the use or inability to use the Application or its services, even if we have been advised of the possibility of such damages.

11. Force majeure  

We are not liable for interruptions in the operation of the service caused by force majeure circumstances (lack of internet, changes in Google Play, hosting, AI infrastructure, cyber incidents, OS updates, etc.).  

12. Termination  

We may suspend or terminate your access to the Application or premium features at any time if you violate these Terms or for technical/security/legal/commercial reasons. Upon termination, your license to use the Application terminates, but the provisions that by their nature should remain in force (for example, limitation of liability, disclaimer of warranties, jurisdiction) remain in effect.  

13. Governing law and jurisdiction  

These Terms are governed by the legislation of Ukraine.  

All disputes arising out of or in connection with these Terms shall be resolved in the manner prescribed by the current legislation of Ukraine.  

14. Changes to the Terms  

We may change these Terms at any time. We will publish the updated version and update the “Official effective date”. Continued use of the Application after such changes means acceptance of the new Terms.
