About LocalGuard

1. What is LocalGuard

LocalGuard is a parental control system designed to operate in your home environment with clear rules, visibility and control from a single panel.

It stems from a simple idea: parental control shouldn't force you to hand over your family's digital activity to an external provider. The project is designed to be deployed on your network and operate as home infrastructure, not as an opaque service.

2. Operating principles

• Private and local: decisions and state live on your own hardware.
• Absolute privacy: zero telemetry and zero functional dependency on third parties.
• Auditable code: the project can be reviewed, deployed and extended without black boxes.
• Realistic operation: Realistic operation on home hardware or simple environments, without bloated architecture.

3. System architecture

LocalGuard consists of three pieces that work together inside your network:

Core (server)

Go backend that handles logic, orchestration and persistence. It's the brain of the system: makes all filtering decisions, stores logs and exposes the REST API consumed by the panel.

Windows Agent

Native binary installed on each PC you want to monitor. Reports network activity and processes to the Core, applies configured rules and inspects SNI traffic without breaking HTTPS or installing certificates.

Web panel

React frontend accessible from any device on your local network. Displays status, configures rules, schedules and manages devices. It doesn't make decisions on its own — everything goes through the Core.

4. Tech stack

• Backend: Go 1.24, REST API, hexagonal architecture.
• Frontend: React 19, Vite, Tailwind CSS, i18next (6 languages).
• Agent: Go compiled for Windows (amd64), native service with watchdog.
• Authentication: PASETO v4 tokens, bcrypt-hashed passwords.
• Database: SQLite — no external dependencies, portable, trivial backup.

5. Deployment

LocalGuard can be set up in a home or technical environment with a guided installation path and clear documentation.

• Home server or simple VPS as a control point.
• Centralized family panel for rules and tracking.
• No cloud requirements, public domain or external static IP needed.

Founders & Leadership

Privacy by Design

At LocalGuard, privacy is not a setting — it is our fundamental architecture. Unlike commercial solutions that promise privacy while collecting 'anonymous telemetry', our code is designed to make it technically impossible for us to see your data.
