Qwerty Chat Privacy Policy

Qwerty Chat Privacy Policy

Last updated: February 2026

Qwerty Chat is designed with privacy as its foundation. We believe private communication is a fundamental human right.

Summary

We do not collect any personal information.

  • No personal data collection
  • No analytics or telemetry
  • No tracking
  • No servers storing user data

How Qwerty Chat Works

Qwerty Chat offers two communication modes:

  • Bluetooth Mesh Chat: Fully offline peer-to-peer communication using Bluetooth Low Energy (BLE).
  • Geohash Chat: Internet-based communication using decentralized Nostr relays for geographic rooms.

Arkraft Technica does not collect, store, transmit, or monitor messages, contacts, or usage activity. All data remains on users’ devices.

Camera Permission (QR Code Scanning)

Qwerty Chat requests access to your device’s camera solely for scanning QR codes.

  • The camera is used in real-time to read QR codes.
  • No photos or videos are captured or stored.
  • No camera data is transmitted to servers.
  • All processing occurs locally on your device.

The camera is never used for background recording, surveillance, or facial recognition.

Location & Bluetooth Permissions

Location access is required by the Android operating system to enable Bluetooth Low Energy scanning. This is a system-level requirement.

  • Location is processed locally to discover nearby peers.
  • Precise GPS coordinates are never collected or transmitted.
  • For Geohash Chat, only a coarse geohash (not exact location) is shared with decentralized relays.

We do not collect, store, or share location history.

Data Stored on Your Device

  • Identity cryptographic key (stored locally in secure storage)
  • Chosen nickname
  • Encrypted message history (if enabled)
  • Favorite peer public keys

This information never leaves your device unless you explicitly share it.

Encryption & Security

All private messages use strong end-to-end encryption, including:

  • X25519 key exchange
  • AES-256-GCM message encryption
  • Ed25519 digital signatures
  • Argon2id for password-protected rooms

What We Never Do

  • Sell or trade personal data
  • Create user profiles
  • Require registration
  • Operate centralized message storage

Data Retention

  • Messages are deleted from memory when the app closes (unless room retention is enabled).
  • Cached messages for offline peers may be temporarily stored for up to 12 hours.
  • Identity keys persist locally until you delete the app.
  • Favorite peers remain until you remove them or uninstall the app.

Children’s Privacy

Qwerty Chat does not knowingly collect information from children. The application does not collect personal information from anyone and does not require account registration.

Your Control

  • Triple-tap the app name to instantly wipe all local data.
  • Close the app to disappear from active sessions.
  • Delete the app to remove all stored data.
  • Revoke permissions at any time in device settings.

Privacy is not a feature of Qwerty Chat — it is the architecture.
