Cookie Policy

01 Introduction

Like many websites, our site may use cookies and comparable technologies to operate effectively, remember your preferences, and understand how visitors interact with our content. We aim to be transparent about these technologies so that you can make informed decisions. This Policy applies to the website operated by Keystone and does not cover the practices of third-party sites or services that we do not control.

02 What Are Cookies

Cookies are small text files that a website places on your device when you visit. They allow the site to recognize your device, store certain information about your visit, and improve your overall experience. Cookies may be set by the website you are visiting, known as first-party cookies, or by other organizations whose services appear on the page, known as third-party cookies. Similar technologies such as local storage, pixels, and tags can perform comparable functions, and references to "cookies" in this Policy include these technologies where relevant.

03 Why We Use Cookies and Similar Technologies

We use these technologies for a limited set of purposes, which may include to:

• Enable core functionality and allow the website to operate correctly;
• Remember your preferences, such as your selected display theme;
• Understand, in aggregate, how the website is used so we can improve it;
• Maintain the security and integrity of the website.

We do not use cookies to collect more information than is reasonably necessary for these purposes.

04 Types of Cookies We Use

The technologies used on our website generally fall into the following categories:

• Strictly necessary — required for the website to function and for features you request, such as page navigation and security. These cannot usually be switched off without affecting the website.
• Functional — used to remember choices you make, such as your light or dark display preference, so the website behaves the way you expect on return visits.
• Performance and analytics — where used, these help us understand how visitors engage with the website in aggregate, so we can improve content and usability.
• Targeting — we do not use cookies to build advertising profiles of you. If this ever changes, we will update this Policy and seek consent where required.

05 Display Preference Storage

Our website lets you switch between a light and a dark display theme. To remember your choice between visits, we store a small preference value in your browser's local storage on your own device. This value relates only to your display preference, is not used to identify you, and is not shared with any third party. You can clear it at any time through your browser settings, after which the website will return to its default theme.

06 First-Party and Third-Party Cookies

First-party cookies are set directly by our website and are used to support its operation and your preferences. Third-party cookies, where present, are set by external providers whose functionality may appear on our pages. Any third-party technologies are governed by the privacy and cookie policies of the respective providers, and we encourage you to review those policies. We do not control how third parties use information collected through their own technologies.

07 Other Tracking Technologies

In addition to cookies and local storage, websites may use technologies such as web beacons, pixels, and tags. These are typically small pieces of code that can help measure usage or confirm that content has loaded. Where we use such technologies, they serve the same limited purposes described in this Policy and are subject to the same commitment to data minimization.

08 How Long Cookies Last

Cookies may be either session-based or persistent. Session cookies are temporary and are removed when you close your browser. Persistent cookies remain on your device for a defined period or until you delete them, and allow the website to remember information across visits, such as your display preference. The duration of any given cookie depends on its purpose, and you can remove stored data at any time through your browser controls.

09 Managing Your Preferences

You have control over cookies and similar technologies. Most browsers allow you to view, manage, block, or delete cookies and to clear local storage. You can usually find these options in your browser's settings or preferences menu. You may choose to accept all cookies, to be notified when a cookie is set, or to refuse cookies altogether. Please note that refusing or deleting certain cookies may affect the functionality of the website.

10 Browser Controls

The exact steps for managing cookies vary by browser and device. In general, you can adjust these settings in the privacy or security section of your browser. Help resources provided by your browser explain how to clear cookies and site data, block cookies from specific sites, and manage stored data. If you use multiple browsers or devices, you may need to update your preferences on each one separately.

11 Do Not Track Signals

Some browsers offer a "Do Not Track" feature that signals your preference not to be tracked. There is currently no uniform industry standard for how such signals should be interpreted. Our website responds to clearly expressed preferences where reasonably able to do so, and we limit our use of tracking technologies to the purposes described in this Policy regardless of whether such a signal is present.

12 Consequences of Disabling Cookies

You are free to disable cookies and clear stored data at any time. If you do so, parts of the website may not function as intended, and certain preferences, such as your selected display theme, may not be remembered between visits. Strictly necessary technologies are important for the website to operate correctly, and disabling them may limit your ability to use some features.

13 Third-Party Services

Where our website relies on third-party services, those providers may use their own cookies or similar technologies subject to their own policies. We are not responsible for the practices of these third parties. We encourage you to review the relevant provider's privacy and cookie policies to understand how they collect and use information through their technologies.

14 Updates to This Cookie Policy

We may update this Cookie Policy from time to time to reflect changes in the technologies we use, our practices, or legal requirements. The updated version will be posted on this page with a revised "last updated" date. Your continued use of the website after the changes take effect indicates your acceptance of the revised Policy. We encourage you to review this page periodically to stay informed.
