01 · Bugs & help
Report a bug or ask for help
Stuck, confused, or something broke? Email us with your Kerf version and a quick repro. Small team, usually a few business days — sometimes faster if the fix is obvious.
We actually read these.
Three places to reach us, split by intent so nothing gets lost. The fastest paths are from inside Kerf — the Help → Report a problem menu item and the avatar menu both prefill the right channel with your app version and platform.

02 · Features

All feature work is prioritised from the public backlog. Upvote what matters to you, or open a new discussion. We read everything; we can't build everything.
03 · Security
Report a security issue
Privately, please — don't file a public issue. We acknowledge within 72 hours and work to a 90-day coordinated disclosure by default. Full policy in SECURITY.md.
Frequently asked
How do I get my Pro license on a new machine?
Sign in with the same Smoothgrain account you used to buy Kerf (avatar menu → Sign in). The license travels with your account, not the device. If you're stuck, email support@smoothgrain.app.
How do I get a refund?
LemonSqueezy handles billing. Email us at support@smoothgrain.app within 14 days of purchase and we'll sort it — no forms, no friction.
Does Kerf collect data?
No analytics or telemetry inside the app itself. The auth flow and license check call our server (smoothgrain.app); that's it. The files you edit never leave your machine.
Is the source code public?
The Kerf app source is private, but all bug reports and feature requests live on the public kerf-issues repo so you can see what's being worked on.
I'm not sure which channel to use.
Default to support@smoothgrain.app. We'll redirect you if it's better suited to the public tracker.
Still stuck?
and we'll help you sort it. Or email support@smoothgrain.app if that's easier.
