This Licence Agreement ("Agreement") sets out the terms under which you (the "Licensee") may install and use the Kerno software (the "Software"). It applies to every paid tier — Pro, Lifetime, and White-label — and to the free trial mode. By installing or using the Software you agree to these terms.
1. Grant of licence
Subject to payment of the applicable fee and these terms, we grant you a non-exclusive, non-transferable, revocable licence to install and run the Software on infrastructure you own or lawfully control, subject to the per-tier limits below.
- Pro ($899 one-time). One production instance. One year of updates from the date of purchase. Your licence to run the last released version is perpetual; continued access to new releases after year 1 requires either a $299/year renewal or a Lifetime upgrade.
- Lifetime ($1,999 one-time). One production instance. All future updates, forever, for as long as Kerno is commercially available.
- White-label ($4,999 one-time, per brand). One production instance rebrandable under one brand identity you control. Includes the right to resell access to that branded instance to end-users on your terms, provided those end-users only interact with the instance you host. You may not redistribute the Software itself.
- Free 7-day trial. A trial licence key valid for 7 days, single instance, for internal evaluation only. After 7 days the Software enters a grace period and then locks unless replaced with a paid licence. Not for production use, client work, or redistribution. One trial per email address.
2. What the licence does not permit
- Redistributing the Software, in source or binary form, to third parties.
- Removing, obscuring, or altering the "Powered by Kerno" attribution on non-White-label tiers.
- Using the Software to provide a multi-tenant hosted service to third parties, except under the White-label tier.
- Reverse-engineering, decompiling, or disassembling the Software, except to the extent such restriction is prohibited by applicable law.
- Using the Software for any unlawful purpose, or in a manner that infringes the rights of third parties.
3. Updates and renewals
- Pro licences include 12 months of updates from the date of purchase. After 12 months you can continue to run the last released version indefinitely.
- To continue receiving new releases after year 1 on Pro, you may pay $299/year for another 12 months of updates, or upgrade to Lifetime for the difference in price.
- Lifetime licences receive all future updates for the commercial life of the product.
- "Updates" means new versions of the Software released by us. It does not include bespoke development, custom agents, or one-off features — those are separate consulting engagements.
4. Licence key and verification
- We issue a licence key by email within 48 hours of payment clearing.
- Your running instance of the Software may contact our licence-verification server periodically to confirm the key is valid. We do not transmit your data, prompts, or any operational content as part of this check — only the key and a minimal request identifier.
- If verification fails (expired, revoked, or our server unreachable) the Software enters a 7-day grace period during which a banner is shown. If the failure persists beyond 7 days the Software restricts functionality until the key is renewed or the verification server is reachable again.
5. Support
- All paid tiers include email support: first response within 48 hours, best-effort resolution.
- Lifetime and White-label tiers additionally include priority handling.
- Support covers bug reports, licence-key issues, and general usage questions. It does not cover consulting work (custom integrations, tuning agents to your workflow, etc.) — for that, see our consulting options.
6. Your data stays yours
The Software runs on your infrastructure. Your inbox index, conversation history, and learned preferences are stored in your database, on your server. We have no access to them. See the Security page for a detailed data-flow description.
7. Warranty and limitation of liability
The Software is provided "as is" and "as available". We make commercially reasonable efforts to ensure it works as described, and will fix verified defects during the update window. We make no warranty that the Software will meet every customer's specific needs, which is why we offer a free 7-day trial and a 14-day money-back guarantee on every paid tier.
To the maximum extent permitted by applicable law, our total liability to you in connection with this Agreement is limited to the amount you paid for the licence in the 12 months immediately preceding the claim. We are not liable for indirect, incidental, or consequential damages (lost profits, lost data, business interruption). Nothing here limits liability for death or personal injury caused by negligence, or for fraud.
8. Termination
- You may stop using the Software at any time. If you're within the 14-day window you can request a refund; otherwise the fee is non-refundable.
- We may terminate this licence if you materially breach it (e.g. redistribution, White-label resale without a White-label licence). In practice we'll contact you to resolve it before terminating.
- On termination, you must uninstall the Software and destroy or return all copies.
9. Governing law
This Agreement is governed by the laws of England and Wales unless otherwise agreed in writing.

This Licence Agreement is a reasonable starting point drafted in good faith. It is not a substitute for independent legal advice. We recommend you have your own counsel review it before entering a significant engagement.
