Privacy Policy

Last Updated: May 16, 2026

Welcome to BloxMulti. This Privacy Policy explains how we handle your data when you use the BloxMulti desktop application ("the App") and our website.

1. Information We Collect

BloxMulti is designed as a standalone, local Windows desktop application. We prioritize your privacy and collect minimal data.

• Local Data: The App stores your account session tokens (encrypted via Windows DPAPI), window layouts, saved servers, and settings locally on your device. We do not transmit this local data to external databases.
• Telemetry and Analytics: We do not track keystrokes, personal in-game activity, or sell behavioral telemetry.

2. Account Authentication & Premium

To access Premium features and account synchronization, BloxMulti allows you to sign in using Google or Discord. When authenticating, we only collect the minimum information required to manage your account and subscription:

• Email Address: Used as your unique account identifier to link and verify your Premium license.
• Basic Profile Information: Such as your display name and avatar URL, provided securely during OAuth authentication.

We use this information strictly for licensing and authentication. We never sell your personal information to third parties.

3. Google Drive Synchronization

BloxMulti offers an optional Cloud Sync feature that utilizes your Google Drive to store application backups. To provide this service securely and with maximum privacy, we use the "appDataFolder" scope:

• Restricted Access: BloxMulti only has access to a hidden, application-specific folder on your Google Drive. We cannot see, read, or modify any other files or folders in your personal storage.
• Local Encryption: All data (including accounts and settings) is encrypted locally on your machine using AES-CBC-256 with PBKDF2 key derivation and your private password before upload. We cannot decrypt your backup.
• Direct Connection: Your data is transmitted directly between your device and Google's servers. At no point does your backup data pass through or reside unencrypted on our servers.

4. Third-Party Services & Libraries

• Roblox: BloxMulti interacts with the Roblox client to manage sessions and instances. BloxMulti is not affiliated with, maintained, authorized, endorsed, or sponsored by Roblox Corporation.
• Microsoft Edge WebView2: The App uses WebView2 for rendering its interface, which operates under Microsoft's diagnostic standards.
• nlohmann/json: The App utilizes this open-source C++ library for offline configuration parsing.

5. Data Security

Your local account data and cookies reside solely on your computer, secured with Windows Data Protection API (DPAPI). Only license verification records and referral tallies are stored in our secure database.

6. Changes to This Policy

We may update this Privacy Policy from time to time as we add new features. We will notify users of any significant changes via updates to the application or our website.
