Installing TrackShort.
One command with Homebrew and you're done — no warnings. Or download the app directly; that path has one macOS hoop, and it's explained below.
Install with Homebrew
Homebrew removes the download quarantine as it installs, so the app just opens — no Gatekeeper dialog.
Don't have Homebrew?
Paste this first — it's the official installer from brew.sh — then run the command above.
Then open License in the app, paste the key from your account, and press Activate. macOS asks for Input Monitoring the first time you draw a gesture.

Open the DMG and drag TrackShort to Applications.
The usual window with an arrow. Eject the disk image afterwards.
Open it. macOS will refuse the first time.
You'll see "TrackShort" can't be opened because Apple cannot check it for malicious software, or words close to it. This is Gatekeeper, and it says this about every app not signed with a paid Apple Developer certificate. It is not a virus warning and it is not about what TrackShort does. (Homebrew, above, skips this entirely.)
Allow it: System Settings → Privacy & Security.
Scroll to the Security section. There's a line saying TrackShort was blocked, with an Open Anyway button next to it. Press that, confirm, and it opens. You only do this once.
Or strip the quarantine flag in the terminal and skip the dialog:
Grant Input Monitoring, then paste your key.
macOS asks for Input Monitoring the first time TrackShort reads the trackpad — this is the permission the whole product runs on. Accessibility is asked for later, and only if you make a gesture that presses keys. Then open License, paste the key from your account, and press Activate.
Why isn't it signed?
An Apple Developer certificate is a paid yearly subscription, and TrackShort is a one-person product at a one-time price. The trade is honest: use Homebrew and there's no friction at all, or download directly and click through one dialog. The download is served over HTTPS from this site, and the SHA-256 above is what a good download hashes to (shasum -a 256 ~/Downloads/TrackShort.dmg).
Updating
With Homebrew: brew upgrade --cask trackshort. Otherwise TrackShort tells you in Settings → About when a newer version is out and links to the download — it never replaces itself behind your back, because macOS ties your Input Monitoring grant to the exact app it was given to.
