Kernudgeon

Terms of Use

Last updated 13 August 2026

The short version: Kernudgeon is free, it's a work in progress, and you use it at your own risk. The rest of this page says that more carefully.

What Kernudgeon is

Kernudgeon is a macOS app I make. It reads an Xbox controller and sends keyboard shortcuts to Glyphs, so you can kern with your hands off the keyboard.

It's a personal project. It isn't a Fort Foundry product, and it isn't made by, endorsed by, or affiliated with Fort Foundry, Glyphs, Microsoft, or Apple. These terms are between you and me.

It's free

You can download, install, and use Kernudgeon at no charge, for personal or commercial type design work. You don't owe me anything for it.

What you can't do: sell it, rent it, or pass it off as your own, and you can't take it apart to build a competing product. I can stop distributing Kernudgeon or change what it does at any time, though nothing I do reaches back into a copy you already have.

It's a work in progress

Kernudgeon is early software and I'd rather say so than let you find out. It may have bugs, it may behave in ways I didn't intend, and it may stop working the day Apple or Glyphs ships an update. Features can change or disappear between versions. There's no promise of support, fixes, or future releases.

Kernudgeon is provided "as is," without warranty of any kind, express or implied, including any warranty of merchantability, fitness for a particular purpose, or non-infringement.

It types into your font files, so keep backups

Kernudgeon works by holding macOS Accessibility permission and sending real keystrokes to whatever Glyphs window is in front. It drives your font editor the same way your hands would.

That means it can change your work. A stuck trigger, a mapping you forgot, a controller left on the desk with a drifted stick: any of those can put kerning where you didn't want it. Kernudgeon can't tell a wanted keystroke from an unwanted one.

Save often, keep backups, and use version control on files you care about. What ends up in your fonts is your responsibility. I can't undo it, and I'm not liable for it.

macOS will warn you the first time

Kernudgeon isn't notarized by Apple, so macOS refuses to open it on first launch and tells you it can't check the app for malicious software. That's expected, not a sign something's wrong. The Setup steps on the home page walk you through allowing it.

Allowing an un-notarized app is your decision to make. If you'd rather not, don't install it.

Limitation of liability

To the fullest extent the law allows, I am not liable for any damages arising from your use of Kernudgeon. That includes lost or corrupted font files, lost work, lost time, lost income, and any indirect or consequential damages, even where I've been told such damages are possible.

Kernudgeon is free, so my total liability to you is zero.

Some jurisdictions don't allow these limits, so parts of this section may not apply to you.

What I collect

The app collects nothing. Kernudgeon has no accounts, no telemetry, and no advertising. It doesn't phone home. It reads the Glyphs document you have open only far enough to count its masters, and that happens on your machine and goes nowhere.

This website collects a little. I count page visits and downloads so I have some idea whether anyone's using Kernudgeon. That includes your IP address, which I use to tell one visitor from another and then only in aggregate.

I don't sell it, I don't share it, I don't tie it to your name, and there are no advertising trackers on this site. If any of that changes, this page changes with it.

Changes to these terms

I may update these terms as Kernudgeon changes. The date at the top tells you when they last moved. Using a version you download after an update means you accept the terms as they stand then.

Governing law

These terms are governed by the laws of the State of Georgia, without regard to its conflict-of-law rules. Any dispute arising out of them belongs in the state or federal courts sitting in Clarke County, Georgia.

Questions

If something here is unclear, ask before you rely on it.
