1. What Are Cookies?

A cookie is a small text file that is placed on your device (computer, mobile phone, or tablet) when you visit a website. Cookies are widely used to make websites work more efficiently and to provide information to the website owner.

Most cookies contain a unique identifier called a cookie ID, which is a string of characters that websites and servers associate with the browser on your device. This allows websites to:

  • Remember your preferences and settings
  • Understand how you use the website
  • Track conversions and affiliate sales
  • Provide personalized experiences
  • Analyze website performance

Cookies do not contain viruses or malware and cannot access other files on your device. However, they do allow websites to collect information about your browsing activity.

2. Cookie Categories

Cookies can be classified by type and by purpose. We use the following categories:

2.1 Essential Cookies

These cookies are necessary for the website to function properly. They enable core functionality such as:

  • Maintaining your session while browsing
  • Remembering your login information
  • Securing transactions and preventing fraud
  • Complying with legal requirements

Legal basis: Contract and legal obligation. These cookies are necessary for the website to function and do not require consent.

2.2 Preference Cookies

These cookies store information about your preferences and choices to enhance your experience:

  • Language and locale preferences
  • Saved plant wishlists and searches
  • Display preferences (dark mode, layout choices)

Legal basis: Consent and legitimate interest. While not strictly necessary, these cookies significantly improve user experience.

2.3 Analytics Cookies

These cookies help us understand how visitors use our website so we can improve it. They collect anonymous data about:

  • Pages visited and time spent on each page
  • Links clicked and user flow
  • Browser type and operating system
  • General geographic location
  • Traffic sources and referrals

Privacy-friendly approach: We use Plausible Analytics and PostHog, which are GDPR-compliant analytics tools that:

  • Do not track individual users across websites
  • Do not use cookies for tracking (in the case of Plausible)
  • Aggregate data to prevent individual identification
  • Comply with all UK GDPR requirements

Legal basis: Consent and legitimate interests in understanding user behavior to improve our service.

2.4 Affiliate and Marketing Cookies

These cookies track your interactions with retailer links to enable our affiliate commission program:

  • Tracking which retailer links you click
  • Recording if you complete a purchase
  • Verifying commission eligibility
  • Preventing fraud and duplicate commissions

Important: Affiliate cookies may be set by third-party networks (Awin, CJ Affiliate, Amazon Associates) and are governed by their privacy policies. These networks may track your activity across multiple websites.

Legal basis: Contract (our affiliate agreements) and legitimate interests in operating our affiliate program.
