Cookies are small text files that are stored on your device when you visit a website. They are widely used to make websites work more efficiently and provide information to website owners. Cookies help us understand how you use our website, remember your preferences, and improve your overall experience. This Cookie Policy explains how CrystalSummarium uses cookies and similar technologies on our website.
We use cookies for several important purposes: to ensure our website functions properly, to analyse how visitors use our site, to remember your preferences and settings, to provide personalised content and advertisements, and to measure the effectiveness of our marketing campaigns. Cookies help us deliver a better, more personalised experience and enable us to continuously improve our services.
These cookies are essential for the basic functionality of our website. They enable core features such as security, network management, and accessibility. You cannot opt out of these cookies as they are necessary for the website to function properly. These cookies do not store any personally identifiable information.
We use analytics cookies, primarily Google Analytics, to understand how visitors interact with our website. These cookies collect information about how you use our site, including which pages you visit, how long you spend on each page, and any error messages you encounter. This information helps us improve our website's performance and user experience. The data collected is aggregated and anonymous.
Functional cookies enable enhanced functionality and personalisation. They may be set by us or by third-party providers whose services we use. These cookies remember choices you make (such as language preferences) and provide enhanced, more personalised features. They may also be used to provide services you have requested, such as watching videos or commenting on content.
These cookies are used to deliver relevant advertisements and marketing content. We use Google Ads and similar services to show you personalised advertisements based on your interests and browsing behaviour.

Our website uses services from third-party providers that may set their own cookies. These include Google Analytics for website analytics, Google Ads for advertising and remarketing, and Google Fonts for web typography. These third parties have their own privacy policies and cookie practices, which we encourage you to review. We do not control these third-party cookies and recommend checking the relevant third-party websites for more information.
You have several options for managing cookies on our website. You can use our cookie consent banner to accept all cookies, reject non-essential cookies, or customise your preferences by category. You can change your preferences at any time by clearing your browser cookies and revisiting our site, which will show the consent banner again.
Most web browsers allow you to control cookies through their settings. You can typically block all cookies, accept only first-party cookies, or delete existing cookies. However, please note that blocking or deleting cookies may affect your experience on our website and may prevent certain features from working properly. Each browser has different procedures for managing cookies, so please check your browser's help documentation for specific instructions.
We implement Google Consent Mode v2, which adjusts how Google Analytics and Google Ads behave based on your consent choices. When you decline marketing or analytics cookies, these services operate in a privacy-enhanced mode that doesn't use cookies for tracking while still providing aggregated insights. This ensures we respect your privacy preferences while maintaining essential website functionality.
We may update this Cookie Policy from time to time to reflect changes in our practices, technology, or legal requirements. When we make significant changes, we will notify you by updating the "Last updated" date at the top of this policy. We encourage you to review this Cookie Policy periodically to stay informed about how we use cookies.
