Terms of Service

Last updated: 26 August 2026

These terms govern your use of invexsys.com and, unless we have signed a
separate agreement with you, the services INVEXSYS provides. Where a signed
agreement exists, that agreement takes precedence over these terms.

Who we are

INVEXSYS, a limited liability company registered in Egypt, of 9 El Azraa Church St, Rod El-Farag, Cairo, Egypt.

What we provide

We provide technology consulting, custom software development, digital
marketing services, and connected-device (IoT) integration work, together with
ongoing support and hosting for systems we build. Individual engagements are
defined in a written proposal or statement of work that sets out the scope,
the deliverables, the timeline and the fees.

Nothing on this website is an offer to contract. Descriptions of our services
are for information; the terms of any engagement are those in the proposal you
sign.

Using this website

You agree not to:

• use the site in a way that breaks any applicable law;
• attempt to gain unauthorised access to it or to any system connected to it;
• interfere with its operation, or with anyone else’s use of it;
• copy or republish its content without our written permission.

Contacting us and messaging

You may contact us by phone, email, the contact form, or on WhatsApp, Facebook
Messenger and Instagram. When you message us on one of those platforms, that
platform’s own terms apply to the conversation in addition to ours.

We reply to business enquiries during business hours. We are not able to
guarantee a response time on messaging channels, and messages sent through them
should not be used for anything urgent or safety-critical. We will not send you
marketing messages unless you have asked us to, and you can tell us to stop at
any time.

Fees and payment

Fees, currency, payment schedule and any expenses are set out in the proposal
for each engagement. Unless that proposal says otherwise, invoices are payable
within 14 days of issue. We may suspend work on overdue
accounts after giving reasonable notice.

Intellectual property

Our name, logo, and the content of this website belong to us.

For work we produce for you: on full payment, you own the deliverables
specified in your proposal. We keep ownership of anything we developed before
the engagement, and of general tools, libraries, methods and know-how we reuse
across clients — you get a perpetual licence to use those to the extent they
are embedded in your deliverables. Third-party and open-source components keep
their own licences, which we will identify.

Confidentiality

Each of us will keep the other’s confidential information confidential, use it
only for the engagement, and return or destroy it on request. This does not
apply to information that is already public, that we already had, or that we
are legally required to disclose.

Warranties and liability

We will perform our services with reasonable skill and care. Beyond that, and
to the extent the law allows, this website and our services are provided as
they are, without other warranties.

We are not liable for indirect or consequential loss, for lost profits, or for
lost data where you have not kept a reasonable backup. Where we are liable, our
total liability for an engagement is limited to the fees you paid us for that
engagement in the twelve months before the claim. Nothing here limits liability
that cannot be limited by law.

Ending an engagement

Either of us may end an engagement by giving written notice as set out in the
proposal. On termination you pay for work performed up to that date, and we
hand over the deliverables produced and paid for.

Governing law

These terms are governed by the laws of the Arab Republic of Egypt, and the
courts of Cairo have exclusive jurisdiction over any dispute.

Changes

We may update these terms; the date at the top shows when we last did. Changes
apply to engagements agreed after the change, not retrospectively.
