What every HANNCREST app shares

Why choose native macOS apps over Electron?

Truly native

Written in Swift & SwiftUI for macOS — no Electron, no web wrappers. Light on CPU, memory and battery.

Private by design

No account, no sign-in, and zero analytics SDKs inside the apps. Your everyday work stays on your Mac.

Local-first

Core features run on your Mac. Online tools, model downloads, licensing and support reports connect only when needed.

Honest pricing

Generous free tiers and one-time Pro purchases. No subscriptions, ever — buy once, own it.

Transparency & Architecture

Why should you trust HANNCREST?

Most Mac utilities have quietly turned into cloud analytics, background daemons, and forced subscriptions. We built HANNCREST on the exact opposite principles. Here is the unvarnished truth about what runs in our apps, what doesn't, and how you can verify it yourself.

  • ✓ 100% On-Device Core Processing
  • ✓ Zero In-App Analytics & Crash Telemetry SDKs
  • ✓ Lifetime One-Time Ownership (Zero Subscriptions)
  • ✓ Native Swift & SwiftUI for macOS
App Cloud Required? Account / Sign-in In-App Telemetry What Leaves Your Mac Independent Verification
Vitals No None 0 KB · Zero SDKs 0 KB for core monitoring (reads local IOKit, sysctl & SMC in-memory); optional Pro tools like the speed test, DNS benchmark and phone-push alerts connect only when you run them Inspect with Little Snitch, LuLu, or Wireshark: no background traffic outside the features you trigger
Breeze No None 0 KB · Zero SDKs 0 KB for scanning & cleanup (local APFS filesystem only); the Updates detector checks Homebrew/App Store/Sparkle for new versions online, on request No analytics or tracking SDKs in the binary, on either build
StealthShare No None 0 KB · Zero SDKs 0 KB for window masking. Local native on-screen frosted overlay masks drawn via Core Graphics window coordinates Never captures, streams, or records screen pixels to disk or network
Aura No None 0 KB · Zero SDKs 0 KB for rewriting after one-time model download Turn off Wi-Fi: local models rewrite in airplane mode
WhisperType No None 0 KB · Zero SDKs 0 KB for dictation after one-time Whisper model download Audio lives in RAM during dictation and is wiped immediately

Runs locally on your Mac

Every app is compiled in native Swift & SwiftUI. AI inference runs locally on Apple Silicon GPUs and the Neural Engine — no remote API keys, no cloud latency, and no dependency on third-party servers staying online.

Proof: Disconnect your internet completely. Every rewrite, dictation, and scan still works — only features that are inherently online (like a network speed test, model download, or license activation) use a connection.

Zero in-app telemetry SDKs

Not a single analytics or crash-reporting SDK is linked into our Mac app binaries — no Firebase, no Mixpanel, and no Sentry telemetry. (This website uses Google Analytics separately; see our website privacy policy.)

Proof: Inspect app binaries with strings /Applications/AppName.app/Contents/MacOS/* | grep -i analytics — zero telemetry libraries.

Buy once, own it forever

Software is a tool, not a landlord. When you purchase an app, your license is verified via Apple receipt or Lemon Squeezy license activation. There are no monthly subscriptions and no recurring surprise charges.

Proof: 1-time Pro purchases with 14-day trials (and 10 free daily minutes in WhisperType). All future updates for the major version are included.

What are our technical boundaries & system requirements?

We believe trust is earned through complete technical honesty before purchase, not after.

● Vitals Compatibility & Builds

Runs on macOS 13+ (Ventura or later) on both Apple Silicon and Intel Macs. Available directly and on the Mac App Store; the direct build includes hardware readings that Apple’s App Store sandbox restricts (compare the builds).

● Breeze File Safety

Breeze moves files to the macOS Trash first so you can restore anything you ever need; it never permanently deletes behind your back unless you use The Shredder. System Integrity Protection (SIP) protects critical Apple files from any third-party cleaner.

● StealthShare Scope

Does not require Screen Recording permission — it masks windows using native on-screen frosted overlay panels positioned via Core Graphics window coordinates. It masks designated background apps and desktop items, but cannot censor sensitive information or tabs inside an unmasked active window you choose to share.

● WhisperType & Aura AI Requirements

Local AI models require Apple Silicon (M1/M2/M3/M4) for Neural Engine & GPU acceleration and a one-time model download over Wi-Fi. WhisperType and Aura are available now; Aura needs Apple silicon and macOS 15 or later, and is $24.99 once after its 14-day trial.
