How to Download and Install BatChat on Windows
Follow these steps to get batChat download for windows up and running on your machine. The process takes approximately two to three minutes on a typical broadband connection.
Step 1: Download the Installer
Visit the official BatChat website and navigate to the download page. Select the Windows version to download the batChat installer executable (.exe file). The file size is roughly 80 MB for the current version. Always download from the official source to avoid tampered copies.
Step 2: Verify the Checksum
Before running the installer, verify the SHA-256 checksum provided on the download page. You can do this by opening Command Prompt and running certutil -hashfile batchat-setup.exe SHA256. Compare the output with the hash listed on the website. This step ensures the file has not been altered during download.
Step 3: Run the Installer
Double-click the downloaded executable to launch the installation wizard. Windows may display a SmartScreen warning since the application is not signed by a major publisher. Click “More info” and then “Run anyway” to proceed. The installer will guide you through choosing an installation directory and creating desktop shortcuts.
Step 4: Launch and Log In
After installation completes, launch BatChat from your desktop or Start menu. If you already have an account on mobile, scan the QR code displayed in the app to link your device. New users can register directly within the desktop client using a phone number. Verification is handled via an SMS code.
Step 5: Configure Settings
Once logged in, review the privacy settings. Enable self-destructing messages by default, configure notification preferences, and set up a local passcode for additional security. These settings are optional but recommended for users who want maximum protection.
Troubleshooting Common Installation Problems
Most users install BatChat without issues, but a few common problems come up repeatedly. Here are the fixes for the ones we see most often.
SmartScreen blocks the installer. This is the most frequent complaint. Windows SmartScreen flags any unsigned executable, and BatChat is no exception. Click “More info” then “Run anyway.” If that option does not appear, right-click the .exe file, select Properties, check the “Unblock” box at the bottom, and click Apply before running again.
The app crashes on launch. This usually points to outdated graphics drivers or missing Visual C++ redistributables. Download the latest Microsoft Visual C++ Redistributable from the official Microsoft site and install it. If the problem persists, try running BatChat in compatibility mode for Windows 10.
QR code scanning fails. Make sure both your phone and desktop are connected to the internet. The QR code refreshes every 60 seconds, so if it expires before you scan it, wait for the new one. Also ensure your phone camera has permission to scan within BatChat mobile.
Security Architecture: How BatChat Protects Your Data
Understanding the security model behind your encrypted chat application helps you make informed decisions. BatChat employs a layered cryptographic architecture that goes beyond basic TLS transport encryption.
End-to-End Encryption (AES-256 + RSA-4096)
Every message sent through BatChat is encrypted on the sender’s device before it leaves the application. The server only sees ciphertext and has no ability to decrypt the content. BatChat uses AES-256 for symmetric encryption of message payloads and RSA-4096 for asymmetric key exchange during session setup.
Here is how RSA-4096 key exchange works in practice: when two users start a conversation, each device generates a unique key pair — a public key and a private key. The public key is shared with the other party through BatChat’s key server, while the private key never leaves the device. To establish a shared secret, the sender encrypts a randomly generated AES session key using the recipient’s RSA-4096 public key. Only the recipient’s private key can decrypt this session key. From that point forward, both sides use the AES-256 session key for fast symmetric encryption of all messages in that conversation. According to NIST research, RSA-4096 remains computationally infeasible to break with current classical computing, though BatChat’s roadmap includes a planned migration to post-quantum cryptographic algorithms by 2027.

Secure Remote Password (SRP) Protocol
Authentication uses the SRP protocol, which means your password never travels to the server in plaintext or even as a hash. Instead, SRP performs a zero-knowledge proof that verifies your identity without exposing your credentials. Even if the server database is breached, your password remains protected because the server never actually stores or receives it.
The SRP authentication flow works as follows: when you register, your client sends a cryptographic verifier derived from your password and a random salt to the server — never the password itself. During login, the client and server exchange mathematical proofs based on Diffie-Hellman key agreement. The client proves it knows the password without ever transmitting it or any equivalent that could be used to derive it. This is a standardized protocol (RFC 5054) widely reviewed by the cryptographic community.
This is a significant advantage over applications that use simple hash-based authentication. SRP makes credential stuffing and database leaks far less dangerous for users.
Local Data Encryption
Messages stored locally on your Windows machine are encrypted using the same AES-256 standard. The local database is protected by a key derived from your device’s credentials. If someone gains physical access to your computer, they cannot read your message history without your passcode.
Open Source and Auditable
The BatChat client code is open source and available for public review on GitHub. Independent security researchers regularly audit the codebase. Any vulnerabilities discovered through these audits are patched promptly and disclosed through BatChat’s security advisory channel.

Frequently Asked Questions
Is BatChat free to use on Windows?
Yes. BatChat is completely free with no subscription tiers, no in-app purchases, and no premium features locked behind a paywall. The development is funded through donations and grants from privacy-focused organizations.
Does BatChat work on Windows 7 or Windows 8?
The current version of batChat windows requires Windows 10 or later. Support for older operating systems ended in 2024 due to cryptographic library dependencies that are no longer maintained for those platforms.
Can I use BatChat on multiple Windows devices simultaneously?
Yes. BatChat supports multi-device login. You can be logged in on your desktop workstation and laptop at the same time. Messages sync across all connected devices in real time.
How does BatChat handle file transfers?
Files are encrypted on the sender’s device, uploaded to the server as ciphertext, and decrypted only on the recipient’s device. The server cannot inspect file contents. Supported file types include documents, images, videos, and archives up to 2 GB per transfer.
Is my data stored on BatChat’s servers?
Encrypted message data is stored temporarily to facilitate delivery to offline recipients and multi-device sync. Once all intended recipients have received a message, the server deletes it within 14 days. BatChat does not collect metadata such as message timestamps, delivery receipts, or user locations.
How do I update BatChat on Windows?
BatChat includes an automatic update mechanism. When a new version is available, the application downloads and installs it in the background. You can also check for updates manually in the Settings menu under “About.”
Can I migrate my data from another messenger to BatChat?
BatChat does not currently offer built-in migration tools from other platforms. However, you can export chat histories from most messengers as text or JSON files and import them manually into BatChat’s local storage using the desktop client’s import feature.
What happens if I forget my BatChat passcode?
If you forget your local passcode, you can reset it through the account recovery flow. You will need access to your registered phone number to receive a verification code. Note that resetting the passcode clears the locally cached message database for security reasons. Messages will re-sync from the server for conversations that have not yet been deleted.
Does BatChat support keyboard shortcuts on Windows?
Yes. The desktop client supports a range of keyboard shortcuts for power users. Press Ctrl+N to start a new chat, Ctrl+Shift+M to mute notifications, Ctrl+E to search conversations, and Ctrl+Shift+D to toggle dark mode. A full list of shortcuts is available under Settings → Keyboard Shortcuts.
Can I use BatChat behind a corporate firewall or VPN?
In most cases, yes. BatChat connects over standard HTTPS (port 443) for message delivery and WebSockets for real-time notifications. If your corporate network blocks WebSocket connections, the app automatically falls back to long-polling. For users in restrictive network environments, BatChat also supports proxy configuration under Settings → Network. Check our blog for advanced proxy setup guides.
