The terms, in plain words.

Who we are

This site is operated by OLTRX, trading as OLTRX, [ADD: entity type] registered in the United States under number [ADD: reg number], at [ADD: address]. You can reach us at hello@oltrx.io. In these terms, “we” and “us” mean that company, and “you” means the person or organization using the site or engaging us.

Using this site

You may read this site, and quote or link to it with attribution. You may not copy it wholesale, scrape it at a rate that degrades it for others, or present it as your own.

Everything on these pages is general information about what we do. It is not professional, legal, financial or technical advice for your situation, and nothing on the site creates a contract on its own. A contract exists only when we have both agreed a written scope.

We try to keep the site up and correct, but we do not promise it will always be available or free of errors.

Quotes and how work starts

Prices shown or discussed before a written scope are estimates, not offers. A project begins when we send you a written scope, setting out what we will build, what it costs and our estimate of when it lands, and you accept it in writing. That scope, together with these terms, is the agreement. Where the two conflict, the scope wins.

Timescales in a scope are estimates made in good faith. They assume you give us what we have asked for when we have asked for it. They are not guarantees, and we are not liable for a delay caused by something outside our control.

Changing what was agreed is fine and normal. Substantial changes may alter the price or the date, and we will tell you before doing the work rather than afterwards.

Payment

Fees, instalments and the invoicing schedule are set out in your scope. Unless it says otherwise, invoices are payable within 14 days.

We may charge interest on amounts more than 30 days overdue at the statutory rate applicable in the United States, and we may pause work on written notice while an invoice remains unpaid. We would rather talk to you first; if cash flow is the problem, tell us.

Fees exclude sales tax or VAT, which is added where it applies. Third-party costs, hosting, domains, paid APIs, licenses , are yours unless the scope says we are covering them.

What we need from you

To do the work we need timely access to the data, accounts, systems and decisions the scope depends on, and a named person who can answer questions and approve things.

You confirm that you have the right to give us the data you give us, and that doing so does not break a law or somebody else’s agreement. If we process personal data on your behalf, we will sign a data processing agreement first.

Who owns the work

You own what we build for you. On full payment, all intellectual property rights in the deliverables made specifically for you pass to you, and we will transfer the repository to an account you control.

Two carve-outs, so there are no surprises later:

• Our pre-existing tools. We reuse our own libraries, templates and starter code across clients. We keep those, and you get a perpetual, worldwide, royalty-free license to use them as part of your deliverables. You cannot resell them on their own.
• Third-party components. Open-source libraries stay under their own licenses, which we will name in the handover. Some carry obligations, and we will tell you which.

Where we license one of our turnkey products for you to run under your own brand, ownership does not transfer; the license terms in your scope govern instead.

We would like to describe the work in general terms as a case study. We will not do that without your written permission, and never with your confidential information or data.

Training, projects and interview help

Our project tracks and sessions are educational. We teach, review your code and unblock you. We do not complete assessed work on your behalf, and we do not write, submit or ghost-produce a take-home task, a coursework submission or an interview exercise for you.

You are responsible for complying with the rules of whoever set the task. Passing off work as your own when it is not can cost you an offer, a reference or a qualification, and that is on you, not on us. If you ask us to cross that line, we will decline and may end the engagement without a refund of time already spent.

We do not promise that a project, a session or a review will get you a job, an interview or a particular grade. Nobody honestly can.

What we promise, and what we don’t

We promise to carry out the services with reasonable care and skill, by people competent to do them, and that the deliverables will materially match the scope we agreed.

If something we delivered does not match the scope, tell us within 30 days of delivery and we will fix it at no charge. That is your primary remedy for defective work.

We do not promise that software will be free of every bug, that a model will reach a particular level of accuracy, that a forecast will prove correct, or that a system will run uninterrupted. Analysis and models describe the data we were given; decisions you take on them remain yours.

Beyond what is written here and in your scope, and to the extent the law allows, we exclude all other terms, conditions and warranties, whether express or implied.

Liability

Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be limited. If you are a consumer, your statutory rights are unaffected.

Subject to that, and where you are engaging us as a business:

• Our total liability arising out of an engagement is capped at the total fees you have paid us under that engagement in the 12 months before the claim.
• We are not liable for loss of profit, revenue, business, goodwill, anticipated savings, or for loss or corruption of data, in each case whether direct or indirect.
• We are not liable for anything caused by your own systems, by a third-party service, or by your use of a deliverable in a way the scope did not contemplate.

Keep your own backups. We keep ours, but yours are the ones you control.

Confidentiality

Each of us will keep the other’s confidential information confidential, use it only for the engagement, and protect it as carefully as our own. This does not cover information that is already public, that you or we already knew, or that we are legally required to disclose. It lasts for five years after the engagement ends, and indefinitely for anything that is a trade secret.

Ending an engagement

Either of us may end an engagement on 14 days’ written notice. Either of us may end it immediately if the other commits a material breach and does not fix it within 14 days of being asked to, or becomes insolvent.

On termination you pay for work done up to that point and for commitments we cannot cancel. We hand over what has been paid for. The clauses on intellectual property, confidentiality, liability and governing law survive.

If you are a consumer

You are a consumer if you are engaging us for purposes outside your trade, business or profession, which will be most people buying a project track, a session or interview help.

Nothing in these terms removes or limits rights you have under consumer law that cannot be removed or limited by agreement. That includes rights to services carried out with reasonable care and skill, and remedies if they are not. The liability cap and the exclusions of indirect loss above do not apply to you.

Your cancellation and refund rights, including the 14-day right to withdraw in the EU and the UK and the 7-day right of regret in Brazil, are set out in the refund policy, which forms part of these terms.

If you are in the EU and we cannot settle a dispute between us, you can approach an approved alternative dispute resolution body. The European Commission lists them by country at consumer-redress.ec.europa.eu, and the European Consumer Centres Network can help with cross-border disputes. (The Commission’s old ODR platform closed on 20 July 2025 and no longer exists.) We would much rather you emailed us first and gave us a chance to put it right.

Governing law

These terms are governed by the law of [ADD: governing law], and the courts of [ADD: courts] have jurisdiction.

If you are a consumer, this does not deprive you of the protection of the mandatory law of the country where you live, and you may bring proceedings in your own local courts.

Changes

We may update these terms. The version that applies to your engagement is the one in force when you accepted your scope; changes do not apply retrospectively. Changes to the site terms take effect when published here.

If any part of these terms turns out to be unenforceable, the rest stays in force.
