I need a self-contained mobile and web app that runs on both iOS, Android, and web browsers and functions as a secure vault for personal records. Inside the app, a user can create a new entry, attach text details, images, or full documents, and then view, edit, or delete those entries whenever needed. Everything has to live in a well-structured local database, with metadata stored alongside any file the user uploads so it stays searchable and organized. Access to the vault must be gated by biometric authentication—Face ID, Touch ID, or the Android equivalents. Once unlocked, the user should move through a clean, minimal interface that makes adding or browsing records feel as familiar as a standard notes app. Under the hood, I will need basic CRUD endpoints so future services can sync or back up data once we expand; for now, they can remain minimal and self-hosted. The exact schema, encryption approach, and any third-party libraries will be finalized after we sign an NDA, which is required before code or design assets are shared. At delivery I expect: • A fully compiled iOS, Android, and Web app build ready for internal testing • Modular-based source code with clear documentation of the database layer, biometric integration, and API endpoints • A concise README that lets another developer spin up the project in one step If you specialize in secure storage and cross-platform toolkits like Flutter or React Native and can hand over clean, well-commented code, let’s talk; I can get the NDA to you right away.

Hello, I’m Muhammad Awais. I will deliver a secure, offline-first Personal Record Vault for iOS, Android, and web, with a clean, minimal UI that feels like a notes app. The app will let you create entries, attach text, images, or documents, and view, edit, or delete them, all stored in a well-structured local database with metadata for fast search. Access is gated by biometric authentication (Face ID/Touch ID/Android equivalents). The architecture will be modular, with a clear data layer, biometric integration, and minimal self-hosted endpoints to support future syncing. I’ll provide comprehensive documentation for the database, biometric integration, and API endpoints, plus a concise README to spin up the project. The exact schema, encryption approach, and any libraries will be finalized after we sign an NDA. Deliverables include fully compiled iOS, Android, and Web builds for internal testing; modular source with inline comments; and a one-step setup guide. Bid: 1200 USD. Duration: 22 days. 1) Do you have a preferred cross-platform toolkit (Flutter or React Native) or should I propose one? 2) Do you have any encryption or key management requirements for local data (at-rest encryption, biometric integration scope)? 3) Do you have a preferred local data schema or should I design a flexible, search-friendly model for entries and metadata? 4) What NDA timing and data handling constraints should we follow before sharing code or design assets? 5) What are your expectations f

Greetings, We can build your self-contained cross-platform vault app for iOS, Android, and web, with secure local storage, metadata indexing, CRUD operations, and biometric authentication (Face ID/Touch ID/Android equivalents). Users will have a clean, minimal interface for adding, browsing, editing, or deleting entries with text, images, or documents. A few questions to align scope, 1. Any preferred cross-platform framework, Flutter or React Native? 2. Should encryption be client-side only, or is server-side backup anticipated? 3. Are there file size or type restrictions for uploads? Our team delivers modular, secure, cross-platform apps with clean code, documented database layers, biometric integration, and ready-to-test builds. Let us chat so we can review your requirements and propose milestones, bid amount is a placeholder to submit. Regards, Yasir LEADconcept PS: We can share past secure storage and cross-platform projects to demonstrate our expertise.

I have signed the NDA as mentioned in your job post, so I’m ready to discuss the technical approach in detail and move forward immediately. What you’re building is essentially a personal, biometric secured vault that must feel as simple as a notes app while behaving like a secure records system under the hood. That balance between usability and security is exactly where I focus. How I’d approach this • Build a single cross platform codebase using Flutter or React Native that runs consistently on iOS, Android, and Web • Implement biometric gated access using Face ID, Touch ID, and Android Biometrics with secure fallback handling • Design a clean, minimal UI for creating, browsing, editing, and deleting records with text, images, and documents • Store everything in a structured local database with searchable metadata tied to each file • Encrypt sensitive data at rest and clearly separate storage, cryptography, and UI layers for maintainability • Expose lightweight CRUD APIs so future sync or backup services can plug in without refactoring The result is a self contained vault today, but architected so it can grow into a synced or backed up system later without compromise. If you’re looking for clean architecture, strong security fundamentals, and a calm user experience, I’m ready to proceed under the NDA and propose the final stack and timeline. Best regards Jenifer

Hi — Elias from Miami. I read your vault brief and I’m very interested. I build secure cross-platform apps (Flutter & React Native) with strong local DB designs, biometric gating, and minimal CRUD endpoints for future sync. I’ll deliver compiled iOS/Android/Web builds, modular source, docs for DB + biometrics + API, and a 1-step README. NDA before sharing code/design is fine. A few targeted questions to scope correctly: Q1: Encryption — do you want device-only encryption (keys in Secure Enclave/Keystore) or end-to-end with a user passphrase that we never send to the server? Q2: File types & limits — which document/image formats and max file size per record should I design for (e.g., PDFs up to 50MB)? Q3: Local DB preference — SQLite (with SQLBrite/Drift), Realm, or do you want a recommendation based on offline-first indexing/search requirements? Q4: Biometric fallback & recovery — if biometrics fail or device is lost, should we support PIN/Phrase recovery, cloud-backup restore, or a combination? If this looks good I’ll sign your NDA and prepare a short proposal with milestones and sample apps. Cheers — Elias.

Hello, I will build a simple and secure vault app that feels familiar, like a notes app, but keeps personal records safe. I will make sure users can add text, images, and documents, and manage everything easily inside a clean interface. I will lock access behind Face ID, Touch ID, or the Android equivalent so privacy comes first. Behind the scenes, I will keep the data well organized in a local database and prepare clean endpoints so syncing or backups can be added later. I will keep the code modular, documented, and easy for another developer to pick up after handover. Looking forward to discussing further. Best Regards, Kamran.
