Our apps stand on a lot of shoulders. This page names the open-source software, frameworks, and services that DeadStick Digital's apps and website rely on. Each project's own license governs how it may be used; the license texts are reproduced in-app under Settings → About → Licenses. If we've forgotten anyone, please let us know and we will correct it.

A note on completeness. The list below names the major frameworks and libraries used by each app at release. Each app bundles a full license file in-app under Settings → About → Licenses that enumerates every transitive dependency with its SPDX identifier and copyright notice; this page is the human-readable summary.

1. ClawMelt

ClawMelt is a Flutter-based desktop app with a Python training engine underneath. It owes its existence to the work of the teams and communities behind:

  • Flutter — cross-platform UI framework, BSD 3-Clause License. © Google LLC.
  • Python — the language that powers the training engine, PSF License.
  • MLX and MLX-LM — Apple's array framework and LLM toolkit for Apple Silicon, MIT License. © Apple, Inc.
  • Hugging Face Hub and the Transformers, Datasets, and PEFT libraries — for model weights, dataset loading, and the LoRA / QLoRA / DoRA adapter implementations, Apache 2.0 License. © Hugging Face, Inc.
  • llama.cpp and the GGUF file format — MIT License. © Georgi Gerganov and contributors.
  • safetensors — tensor serialization format, Apache 2.0 License. © Hugging Face, Inc.
  • The prompt-format conventions popularised by the Stanford Alpaca and ChatML projects.

The in-app Licenses screen lists the full set of direct and transitive dependencies for both the Flutter front-end and the Python engine.

2. BillingBird

BillingBird is a React Native app with the Expo SDK and New Architecture enabled. The teams behind these projects make it possible for a very small studio to ship a universal iOS and Android product:

  • React Native 0.76 (Fabric / TurboModules) — MIT License. © Meta Platforms, Inc. and affiliates.
  • Expo SDK 52 and the Expo modules ecosystem — MIT License. © 650 Industries, Inc. and contributors.
  • React — MIT License. © Meta Platforms, Inc. and affiliates.
  • The Apple iCloud and Google Drive APIs, used to store the optional encrypted sync container in your own cloud account.
  • On-device receipt capture via Apple Vision (iOS) and Google ML Kit (Android).
  • PDF rendering and export via the system PDF APIs on each platform.

3. CarrierPigeonVPN

CarrierPigeonVPN's tunnel is built on the WireGuard protocol and its reference implementations. The cryptographic primitives, key exchange, and the two mobile tunnel providers are made possible by:

  • WireGuard — "WireGuard" and the "WireGuard" logo are registered trademarks of Jason A. Donenfeld. The protocol is the foundation of this app.
  • wireguard-go — the userspace WireGuard implementation in Go, MIT License. © Jason A. Donenfeld.
  • wireguard-apple and wireguard-android — the Apple-platform and Android reference clients, MIT License. © Jason A. Donenfeld.
  • Apple's Network Extension framework (NEPacketTunnelProvider) and Android's VpnService API — the platform primitives without which none of this would be possible.

CarrierPigeonVPN is an independent product and is not endorsed by, affiliated with, or sponsored by the WireGuard project or Mr Donenfeld.

4. Pitot

Pitot is a native document scanning and storage app. Its Apple implementation is built on system frameworks and a small set of local-first storage, OCR, and PDF boundaries:

  • Swift and SwiftUI — the language and UI framework for the Apple app surface.
  • VisionKit, Vision, and Core Image — Apple frameworks used for document camera capture, rectangle detection, perspective correction, image enhancement, and on-device OCR.
  • PDFKit — Apple framework used for local PDF assembly and page-level PDF operations.
  • SwiftData and CryptoKit — Apple frameworks used for local document-library metadata and content identity.
  • Kotlin, Jetpack Compose, Room, CameraX, Google ML Kit, and Google Drive appDataFolder APIs are planned for the Android implementation.

5. Website

www.deadstick.net is a hand-written static site served from GitHub Pages. It relies on:

  • GitHub Pages for hosting, served through Cloudflare for TLS and edge caching.
  • Web3Forms — delivers submissions from the contact form to our inbox. Processing is covered by Section 5 of our privacy policy.
  • hCaptcha — bot protection on the contact form. © Intuition Machines, Inc.

6. Typography & type

The system font stack (SF Pro on Apple platforms, Segoe UI Variable on Windows, Roboto on Android) is used throughout, with no custom webfonts loaded from third parties. This keeps our pages fast and keeps your browser from making extra requests you did not ask for.

7. Trademarks & service marks

Apple, the Apple logo, iPhone, iPad, Mac, macOS, and Apple Silicon are trademarks of Apple Inc., registered in the U.S. and other countries and regions. App Store is a service mark of Apple Inc. Google Play and the Google Play logo are trademarks of Google LLC. Android is a trademark of Google LLC. WireGuard is a registered trademark of Jason A. Donenfeld.

8. Corrections & contact

If a project has been misattributed, a license identifier is wrong, or a dependency has been left out, please send a note through the contact form (topic: Something else) and we will correct this page in the next deployment. If you are a rights-holder and wish to be named differently — or not at all — we will honour that.
