How activation works
Try first
Install Kata Community, use any Pro feature — the 14-day free trial starts automatically. No signup, no card. Everything Pro does works identically during the trial.
Purchase
Complete checkout on Lemon Squeezy. You'll receive an email with
your license key (a single KATA-PRO-… string).
Paste key
Open Preferences → Pro, paste your key, click Verify & Activate.
Kata auto-downloads Kata.App.Pro.dll from the license-verified
Pro channel on next launch — no manual DLL drop.
FAQ
Do I need to buy Pro to use Kata?
No. Kata Community is free and open-source (PolyForm Noncommercial) and stays a full viewer forever — editor, class diagram, 114 smell detectors, diff preview. Every Pro feature (apply refactor, AI diff, cross-language rename, governance report) starts with a 14-day free trial — no signup, no card. After the trial, upgrade to keep applying.
Do I pay for AI on top of the license?
No. Kata calls your own AI CLI (Claude Code, Codex, Cursor, or any MCP-compatible tool). Your existing AI subscription covers all requests — Pro doesn't add a per-request charge.
Can I move my license to another machine?
Yes. Open Preferences → Pro → Deactivate license. This releases the seat on the Lemon Squeezy side so you can activate on a new machine.
What if I go offline?
The license key is Ed25519-signed and verified locally — no network check needed to use Pro features once the key is on disk. Only the initial Pro DLL download and updates need internet (verified through the license-authenticated Pro channel).
Refunds?
Contact dhq_boiler@live.jp within 14 days of purchase for a full refund, no questions asked.
Team / Business — how do renewals work?
Yearly subscription via Lemon Squeezy. Cancel anytime from the Lemon Squeezy customer portal. Your Pro features continue until the end of the paid period.
Why does Windows show a SmartScreen warning?
Kata isn't yet Authenticode code-signed, so on first run Windows shows a blue "Windows protected your PC" screen — click More info → Run anyway to proceed. Code signing is on the roadmap; we didn't want to block the v1 launch on the certificate paperwork (slower for Japan-based indie developers). The warning goes away once we ship signed builds.
