Core local-first application
The repository contains the major firearm inventory, ammunition/reloading, maintenance, photo, security, search, and local-data foundations.

Brass & Powder
A privacy-first, fully offline firearm, ammunition, reloading, maintenance, and range-record application designed to keep sensitive records under the user's control.
ParkedLocal-FirstCross-Platform Foundation
Last updated: October 2, 2026. Brass & Powder is parked at its preserved working-state checkpoint while higher-priority products advance. Its substantial React Native foundation is preserved and available for continued improvement without representing the project as abandoned or archived.
Current State
- The working-state checkpoint is preserved; active feature and release work is parked.
- The app is designed to operate fully offline with local SQLite storage.
- The current project is a React Native implementation targeting Android and iOS.
- Release readiness will be re-audited against current mobile toolchains before wider distribution.
Implemented Foundation
- Firearm inventory with photos and search.
- Ammunition and reloading data including powder, bullets, primers, OAL, velocity, and quantities.
- Maintenance records, costs, and related firearm history.
- PIN lock, biometric authentication, secure key storage, local settings, and offline operation.
Privacy & Architecture
- No cloud account is required for core use.
- User records remain stored locally on the device.
- SQLite provides the local data layer with migration and repository/DAO foundations.
- Release signing secrets are intended to remain outside the repository.
Roadmap
Preserve the current baseline
The existing product remains preserved while Horizon Tech concentrates active engineering time on products closer to external testing and launch.
Re-audit, validate, and prepare release
Before broader distribution, the app will receive a fresh build/runtime audit, Android and iOS validation on current toolchains, remaining blocker remediation, and controlled release testing.
Repository Milestones
Working state preserved before GitHub migration
The current application state was committed as a migration checkpoint.
Security and correctness audit remediation
Multiple critical, high, and medium findings were addressed, including PIN-change verification, transaction correctness, lockout behavior, maintenance correctness, biometric naming, migration error handling, and bootstrap error handling.
