SEO OS software licence

The terms attached to every SEO OS purchase, for all three editions.

Version 1.1 · 2026 · Licensor: Emeka Eje, trading as Slipper Digital · Governed by the laws of the Federal Republic of Nigeria · [email protected]

This agreement governs your use of SEO OS V4.0.0. It is a licence to use software, not a sale of the software and not a transfer of its intellectual property.

Read it once. It is written to be understood without a lawyer sitting beside you, and it is deliberately short about the things that are standard and specific about the things that are not: what you may do with the source, what happens when this software changes a live client site, and what has and has not been proven in production.

1. What this licence is, and is not

WHAT THIS LICENCE IS

A perpetual, non-exclusive, non-transferable, worldwide licence to use SEO OS V4.0.0 in your own paid client work, for a one-time fee. You keep the files. There is no renewal, no subscription, and no expiry on the edition you bought.

WHAT THIS LICENCE IS NOT

It is not a transfer of ownership. The Software, its architecture, its detector and scoring logic and its naming remain the property of the Licensor.

It is not a reseller or redistribution agreement. You may use the Software to earn money from your clients. You may not sell, publish or hand on the Software itself, in whole or in part, modified or unmodified.

It is not a hosted service. Nothing here obliges the Licensor to run anything on your behalf, and no part of your engagement data is routed through a Licensor server by the Software as delivered.

It is not a partnership, agency or employment relationship. Your client work, your commercial decisions and your liabilities are your own.

3. Grant of rights, by edition

Each edition carries its own grant. Everything in section 4 onwards applies to all three.

Solo

$249 one-time licence, perpetual, standalone workbench

Covers one named Delivering Consultant

Use the Standalone Workbench for paid client work.

Produce and keep your own client deliverables.

Edition boundary. Solo does not include the companion service. By itself the workbench does not run the automated crawler, JavaScript rendering, search and analytics integrations or any production execution connector. Those capabilities are licensed with Professional and Agency.

Professional

$399 one-time licence, perpetual, full consultant operating system

Covers one named Delivering Consultant

Everything granted under Solo.

Run the Companion Service on machines you control.

Edition boundary. Professional does not include source code, the self-hostable build, or the right to re-brand the software itself. Those are licensed with Agency.

Agency

$1,250 one-time commercial licence, perpetual, source included

Covers every Delivering Consultant working inside the Licensee firm, with no count limit

Everything granted under Professional.

Operate across your whole firm.

Modify and extend the Software for the Licensee's own use.

Host the compiled front end on infrastructure you control.

White-label builds you produce.

Edition boundary. Agency is a licence to operate, extend and brand the Software inside the Licensee firm. It is not a reseller agreement and not a right to distribute the Software, modified or unmodified, to anyone outside that firm.

4. Restrictions

The following are prohibited under every edition. Any of them is a material breach and ends the licence without refund.

You may not redistribute the Software.

You may not operate it as a service for third parties.

You may not claim authorship of the Software.

You may not remove the notices.

You may not transfer the licence.

6. Your client work

Reports, exports, tickets, proposals and any other deliverable you produce with the Software belong to you. The Licensor claims no rights in them, receives no royalty on them, and takes no interest in your client relationships. Client data stays wherever you run the Software.

7. Standard commercial terms

7.1  Payment and delivery

The fee is due in full at purchase. Delivery is the download package for the edition purchased, together with the support term below. Nothing further is required from the Licensor for this licence to have delivered what it promises.

7.2  Taxes

Fees are exclusive of any applicable taxes, VAT, GST or withholding tax, which are the Licensee's responsibility. A payment platform may collect and remit tax on the Licensor's behalf where it is required to.

7.3  Third-party components

The Software includes open-source components, each under its own licence. Those licences are reproduced in the THIRD_PARTY_NOTICES file supplied with the package and are unaffected by this agreement. Where a third-party licence grants the Licensee more than this agreement does in respect of that component, the third-party licence governs that component.

7.4  Responsibility for Production Changes

This is the term that matters most in practice. The Software can write changes to a live site. The Licensee is solely responsible for:

The Software requires explicit consultant approval before execution, applies an additional confirmation gate to canonical and robots or indexing changes, performs a drift check before writing, records a pre-write snapshot, and offers rollback with post-rollback verification. Those controls are safeguards, not guarantees. The Licensor is not responsible for the content, correctness or effect of any change the Licensee approves.

7.5  What has and has not been proven

The Licensee acknowledges the state of verification published with this version:

These statements are made as at the release of this version and are the basis on which the licence fee is paid.

7.6  Data and credentials

The Software is local-first. The workbench and the companion service are designed to run under the Licensee's control, and the Software as delivered does not route engagement data through a Licensor application server. Any credential, API key or token the Licensee configures is the Licensee's to protect. External providers receive only what is necessary for a connection the Licensee explicitly configures.

7.7  No warranty

The Software is provided "as is". To the maximum extent permitted by law, the Licensor disclaims all implied warranties, including merchantability, fitness for a particular purpose and non-infringement, and makes no warranty that the Software will be uninterrupted or error-free, or that its use will produce any particular ranking, traffic, revenue or other business outcome. Its value depends on skilled application.

7.8  Limitation of liability

To the maximum extent permitted by law, the Licensor's total liability under this agreement is limited to the fee the Licensee paid. The Licensor is not liable for indirect, consequential, incidental or special damages, including lost profits, lost traffic or revenue, lost business opportunity, loss of data, or the cost of restoring a system the Licensee changed.

7.9  Indemnification

The Licensee indemnifies the Licensor against claims, damages and liabilities arising from the Licensee's use of the Software in client work, including client disputes, changes made to client systems and business losses attributed to the Licensee's services.

7.10  Updates and editions

Point releases within the purchased major version, where the Licensor publishes them, are provided at no further cost. Nothing obliges the Licensor to publish updates on any schedule or at all, and no part of the fee is contingent on one. A future major version may be offered as a separate paid edition.

7.11  Support

Every edition includes 30 days of email support from the date of purchase, by writing to [email protected]. Support covers:

Support does not include custom development, changes built for the Licensee's workflow, or work on the Licensee's client sites. There is no set response time. Support ends 30 days after purchase whether or not it has been used, and ends with the licence if a refund is issued.

7.12  Changes to these terms

The Licensor may publish revised terms for new licensees at any time. A Licensee who has already purchased keeps the terms in force at the time of their purchase.

7.13  Governing law

This agreement is governed by the laws of the Federal Republic of Nigeria. The parties submit to the courts of that jurisdiction.

8. Refund and termination

14-day fit guarantee

Within 14 days of purchase the Licensee may request a full refund for any reason, by writing to [email protected] with the word "refund" in the subject line. On refund, the rights granted by this licence end immediately and the Licensee must delete the Software from their systems, including any build or deployment made from it.

After the guarantee window

After 14 days the Licensor does not offer a refund as a matter of policy. That is a statement of the Licensor's policy and nothing more. It does not limit two things that sit outside this agreement:

However a refund is issued, the rights granted by this licence end and the deletion obligation above applies.

Termination by the Licensor

The Licensor may terminate this licence immediately, without refund, if the Licensee redistributes the Software, operates it as a service for third parties, claims authorship of it, removes its notices, or transfers the licence.

Termination by the Licensee

The Licensee may stop using the Software at any time. No refund is due after the 14-day window, subject to the paragraph above.

After termination

On termination for breach, the Licensee must stop using the Software and delete it, including any modified build and any hosted deployment. Engagements already in progress may be completed only with the Licensor's written agreement. Client deliverables the Licensee has already produced remain the Licensee's. Confidentiality survives termination.

9. Acknowledgment

By downloading, installing or using the Software, you confirm:

This licence takes effect on payment clearance and is evidenced by the purchase receipt. No signature is required.

This document was prepared for the Licensor's own use and is not legal advice. Have a qualified lawyer in your jurisdiction review it before you rely on it.
