🛡️ Privacy & Security

Your accounts belong to you. Your data should stay under your control.

Keychain is designed to minimize unnecessary data collection and protect sensitive authentication information.

🔐 Encrypted Local Storage

Microsoft authentication tokens are stored locally in an encrypted vault using AES-256-GCM. The encryption key is generated randomly and stored separately from your Minecraft instance.

On supported Windows systems, the key is additionally protected using Windows Data Protection API (DPAPI).

🌐 Secure Microsoft Authentication

Keychain uses OAuth 2.0 with PKCE to authenticate Microsoft accounts through your default web browser.

Your Microsoft password is entered directly on Microsoft's official website, never into Keychain.

🚫 No Tracking or Analytics

Keychain does not include built-in analytics, advertising trackers, or a developer-operated account synchronization service.

Network connections are still required for Microsoft authentication, Xbox and Minecraft services, session refreshing, and loading Minecraft skins.

💾 Local-First Account Management

Your saved accounts remain on your computer. Sharing account data between your own Minecraft instances is optional, and Keychain does not require a separate developer account.

🔓 Open Source & Transparent

Keychain's source code is publicly available on GitHub under the MIT license, allowing anyone to inspect how authentication, account management, and encryption are implemented.

Privacy note: Local encryption protects against accidental exposure of copied account files, but cannot guarantee protection against malware or someone with access to your running computer.
