  [This explanatory note is devoted to the development of a mobile application for secure storage of user data (the Wallenc software product). It describes analysis of the subject area and analogues, requirements formulation, architecture and user interface design, software implementation in Kotlin (Android, Jetpack Compose, Room, Hilt), testing, and a brief economic assessment.]

  [Implemented: the VaultsManager → vault → storage → files hierarchy (one LocalVault on the device, remote vaults via OAuth), client-side AES encryption, service metadata in Room, and a project-level synchronization contour without passing encryption keys to the provider. The source code is hosted in a private GitLab repository at Southern Federal University. Full source listings are in Appendix A; software documentation is in Appendix B.]
