ZengChat - Private Chat on Your Wi-Fi

ZengChat lets you chat privately with people on the same Wi-Fi network, without relying on mobile data for local conversations. Discover nearby users automatically and send messages directly over your local network with a fast, lightweight chat experience.

What makes ZengChat different
Local network chat: Works with people connected to the same Wi-Fi or local network.
Privacy-first messaging: Your local chats are not uploaded to our servers.

Direct encrypted communication: Messages are protected with AES-256-GCM and RSA-2048 key exchange.

Privacy and data control
Local chat messages are stored on your device for your convenience.
You can delete messages and clear conversations at any time.
You can delete your account from Settings > Delete Account by confirming your password.
Account deletion starts immediately and typically completes within minutes.
Deletion removes your Firebase account, profile, feedback, block-list records, and local app data tied to your account.
Messages already delivered to another person remain on their device.

Permissions
Local network / Wi-Fi: To discover and connect with nearby devices
Photos / Media: To send and save images and videos you choose to share
Contacts: Optional, only if you want to share a contact
Biometrics: Optional, only if you enable app lock
Internet: Required for sign-in, account services, premium, ads, and feedback features

Requirements
Both devices must have Wi-Fi enabled and be on the same local network
Android 7.0 or later
Age 13+

Notes
Local chatting is designed for people on the same network.
Some account-related features rely on Firebase services.
Delivered messages stay on recipients' devices unless they delete them.

Make local conversations simple, fast, and private with ZengChat.
