Cookie Policy

Last updated: 26 July 2026

The short version

Ninja Systems currently uses only cookies and similar technologies that are needed to make the site work securely - such as keeping a signed-in session and basket available. We do not currently set analytics, advertising or social-media tracking cookies through this website. If we introduce a non-essential technology, we will ask for your clear choice before it is placed or read.

What cookies are

Cookies are small text files that a website may save on your computer, phone or other device. Similar technologies can store or access information in a browser in other ways. They can help a website remember a session, protect an account, retain a basket, remember a preference, measure use or support advertising. This policy explains the technologies used on the Ninja Systems website and how you can control them.

Why we use them

Strictly necessary

Allows the site to deliver features you request, including signing in, protecting forms, retaining your basket and supporting checkout.

Performance

Would help us understand use of the site. We do not currently use these cookies.

Marketing

Would help measure ads or tailor advertising. We do not currently use these cookies.

NamePHPSESSID
PurposeProvides a secure server-side session. This supports sign-in, form security, the basket and other actions you ask us to perform.
DurationSession; normally removed when you close your browser.

This cookie is strictly necessary. Blocking it may mean that account features, your basket, checkout or security controls do not work properly.

Third parties and payments

When you choose to pay, checkout is handled by Stripe on its hosted payment page. Stripe may use its own cookies or similar technologies to provide and secure its payment service. Those technologies are controlled by Stripe when you use its service. Please read Stripe’s privacy policy for further information.

Links to third-party websites, including social platforms or review services, may take you to a service with its own cookies and privacy practices. We do not control those third-party technologies.

Consent for non-essential cookies

Where the law requires it, we will ask for your consent before using non-essential cookies or similar technologies, including analytics or advertising technologies. You will be able to accept or reject those optional technologies as easily as each other, and you may change your choice later. We will update this policy and any cookie controls when we add or remove technologies.

We do not treat continued browsing, scrolling or closing a notice as consent for non-essential cookies.

How to manage cookies

Most browsers let you review, delete or block cookies through their settings. Blocking all cookies can affect the way websites work, including ours. You can also use private browsing, clear your browser data, or choose a browser extension that limits tracking. Your browser provider can tell you how to make these choices for your specific device.

Legal basis and your privacy

We rely on the strictly necessary exemption for the essential site session described above. If a cookie or similar technology also involves personal data, our handling of that data is explained in our Privacy Policy. For non-essential cookies, we will rely on consent where required.

This policy is intended to be read with our Privacy Policy and Terms. It does not limit any rights you have under applicable data-protection law.

Changes and contact

We may update this policy when the technology we use changes, or when the law or guidance changes. The latest version will always be posted on this page with a revised “last updated” date.

If you have a question about cookies or your personal information, contact support@ninjasystems.co.uk. You may also raise a concern with the UK Information Commissioner’s Office. Its guidance on cookies and similar technologies explains the UK rules in more detail.
