The mobile application does not support repeated updating of its data within the period specified by the state. The developers report that such functionality is not yet available. While there will be an update, it is doubtful that it will be released before July 16, 2024. Although the FAQ in the mobile application states that those liable for military service must update their data within 9 days after changing their address, this cannot be done abroad since the application does not support updating a mobile phone number to a foreign one. It is also important to note that the button to update the actual residential address does not appear on iOS by first using of the mobile application. The data like actually residential address is simply pulled from the registry and cannot be updated.

It is impossible to update data after your first authorisation. It seems was developed for one-time sending information, with no feature to “update” it, as the law requires. So after you enter your data - you cannot change it afterwards.

"👋🏻Hi there!
The Reserve+ doesn’t offer re-updating of personal data. In the next updates, it will be possible to update personal data again. If you need to change your data now, contact the Territorial Center for Recruitment and Social Support or the Center for Administrative and Public Services.
Best regards,
Reserve+ support team"

(Data entered by a person has a high risk of being publicly accessible and in the hands of criminals. Any data from this application has no legal force that confirms this fact. The application is built on the basis of open source developments in which many inconsistencies were found, that is, it is not designed to collect the data it requests. The application does not have the functionality of a request to delete personal data from the database.) The application collects information, because it asks for e-mail, contact phone number and actual place of residence. And also military data. These data are not available in other registers.

Sorry, but all of the mentioned points are simply NOT true.
The application does not collect or share any personal data. It uses the personal data stored in the public register "Oberig" totally in accordance with the Personal Data Protection Law of Ukraine
