License Terms
Short version: one license, one person, used by that person.
- One license, one human. A license is for a single person. You may install it on multiple computers you own, but only one instance may be in use at a time. Licenses are not transferable, shareable, or valid for team or organizational use.
- No reselling or renting access. You may not resell, sublicense, rent, or provide access to Harrington through your license to any other person or entity.
- Human use only. Automation and agents are prohibited. Harrington is designed for human creative work. Use by automated scripts, AI agents, orchestration tools, or any non-human entity — including tools like Claude Desktop, ChatGPT integrations, or similar — is strictly prohibited under any license tier. If an agent is making the decisions, there is no human author. That is the line Harrington will not cross.
- Personal vs. Commercial is a pricing distinction, not a use restriction. Both tiers have identical features and identical terms. The difference is pricing fairness: if you earn professionally from music, the Commercial tier is the right one for you.
Philosophy
The local experience is fully capable — not a stripped-down trial. Premium improves quality, it doesn't unlock basic access. No feature cliffs.
- You stay the author — Harrington suggests, never overrides
- Local-first — your work stays on your machine; works offline
- No subscription for the workbench — buy once, own it through the current major version
FAQ
Which base tier do I need?
Ask yourself: are you a business that makes money from music professionally? If yes — a studio, publisher, or professional songwriter — use the Commercial tier. If you're an individual songwriter, worship leader, student, or part of a non-profit church or organization, the Personal & Non-profit tier is for you.
What does "all 1.x updates included" mean?
Your license covers every update from 1.0 through 1.x — new features, bug fixes, improvements — for no additional charge. When a major version (2.0) eventually releases, existing license holders will be offered an upgrade at a discount. No one gets cut off.
What's the difference between BYOK Premium and Hosted AI?
Both give you the same analysis quality. With BYOK, you supply your own Claude or OpenAI API key and pay those providers directly — more control, often cheaper at low volume. Hosted AI uses a Harrington-managed key — no setup, no provider account, $15/month covers it. Choose whichever fits your workflow.
Does the local AI work without any paid tier?
Yes. The on-device model is included in both base tiers and works fully offline. Premium and Hosted AI add external model access for users who want higher-quality results — they don't gate any local features.
What does Early Access cost?
Nothing. Both Personal and Professional founding creators receive full access — including BYOK — at no charge, in exchange for direct feedback and two video calls with the founder. Post-launch pricing applies to new licenses only; early access users are grandfathered.
Does Harrington send my lyrics to the cloud?
Only if you configure external AI routing (Premium or Hosted AI). The local model runs entirely on your machine. Your songs never leave your device unless you explicitly trigger an external AI request.
