1. OVERVIEW & ZERO-DATA COLLECTION GUARANTEE
--------------------------------------------------------------------------------
Calyx Labs Inc. ("we", "our", or "us") builds privacy-first Android applications
(including Calyx PGP Client and Zappy Bird) as well as Linux distributions and
security utilities (including Calyx Linux, Calyx Terminal, and the Calyx Security
Operations Center).

OUR CORE PRIVACY PRINCIPLE IS SIMPLE:
WE COLLECT NO DATA WHATSOEVER ON OUR USERS.

We do not collect, store, transmit, log, profile, share, or sell any personal
information, device identifiers, usage telemetry, crash analytics, location data,
contacts, or cryptographic material.

2. INFORMATION WE DO NOT COLLECT
--------------------------------------------------------------------------------
When you download, install, or use any Calyx Labs Inc. application from the
Google Play Store or our official repositories:

  * NO Personal Data: We never ask for or collect your name, email address,
    phone number, physical address, or demographic information.
  * NO Telemetry or Analytics: Our apps contain zero third-party analytics SDKs,
    tracking pixels, behavior loggers, or crash reporting agents.
  * NO Advertising Identifiers: Our apps contain no third-party ad networks and
    never read or transmit your Google Advertising ID (AAID).
  * NO Cloud Key or File Syncing: All cryptographic operations, keyrings, files,
    notes, and game scores remain 100% locally stored on your device.

3. APPLICATION-SPECIFIC PRIVACY DETAILS
--------------------------------------------------------------------------------
A. Calyx PGP Client (Package: com.calyxlabs.pgpclient)
   - 100% Local Keyring: All OpenPGP keys (RFC 4880 / RFC 9580, ML-KEM-1024 +
     ML-DSA-87 Post-Quantum suites), passphrases (PBKDF2 + AES-256-GCM),
     encrypted notes, and encrypted file containers (.asc / .pgp) are generated
     and processed strictly offline on your local device hardware.
   - Camera / QR Verification: When using QR code key verification, camera data
     is processed strictly in volatile memory on-device to decode the QR code
     and is never stored or transmitted anywhere.
   - File Access: Selecting local files for encryption or decryption uses the
     standard Android Storage Access Framework (SAF) on your device. Files
     never leave your device.

B. Zappy Bird (Official Release v1.0.0)
   - Local Storage: High scores, preferences, and power-up settings are saved
     strictly on your local device.
   - WiFi Versus Mode: Local WiFi multiplayer communicates directly between
     peer devices on your local network without routing personal data through
     any external Calyx Labs Inc. tracking servers.

C. Calyx Linux, Calyx Terminal & Calyx Security Operations Center (SOC)
   - All system hardening checks, network tunnel inspections, Tor/VPN routing
     monitors, RAM wiping routines, and terminal operations execute locally on
     your machine with zero phone-home telemetry.

4. THIRD-PARTY SERVICES
--------------------------------------------------------------------------------
If you download our Android applications through the Google Play Store, Google
LLC may collect standard store installation metrics governed by your Google
account settings and the Google Privacy Policy (https://policies.google.com/privacy).
Calyx Labs Inc. itself receives no personally identifiable information from
your use of our software.

5. CHILDREN'S PRIVACY (COPPA COMPLIANCE)
--------------------------------------------------------------------------------
Because Calyx Labs Inc. collects no personal data, usage data, or device
identifiers from any user of any age, our applications fully comply with the
Children's Online Privacy Protection Act (COPPA) and international equivalents.
