This policy explains how Prismlight Analytics uses cookies. Read it alongside our Privacy Policy.
1. What Cookies Are
Cookies are small text files stored on your device when you visit a website. They help sites work properly, remember preferences, and collect usage information. Cookies can be persistent (they stay until they expire or you delete them) or session-based (they disappear when you close your browser).
2. How We Use Them
We use cookies for three purposes: keeping the site functional, understanding how people use it, and measuring advertising effectiveness. Non-essential cookies are only activated after you give explicit consent.
3. Cookie Categories
3.1 Strictly Necessary
These keep the site working. They cannot be switched off.
| Cookie | Purpose | Duration | Type |
|---|---|---|---|
PHPSESSID | Session state | Session | First-party |
pl_lang | Language preference | 1 year | First-party |
pl_csrf | CSRF protection | Session | First-party |
pl_consent | Your cookie choices | 1 year | First-party |
Legal basis: strictly necessary for the service. No consent required.
3.2 Analytics (consent required)
These help us understand how visitors use the site. Only set after you grant consent.
| Cookie | Purpose | Duration | Type |
|---|---|---|---|
_ga | Distinguishes unique users (random identifier) | 2 years | Third-party (Google) |
_gid | Distinguishes users within a session | 24 hours | Third-party (Google) |
_gat | Throttles request rate | 1 minute | Third-party (Google) |
Legal basis: consent (Art. 6(1)(a) GDPR).
We use Google Analytics consent mode v2. By default, ad_storage and analytics_storage are both denied. When you grant analytics consent, analytics_storage is updated to granted and the scripts load.
3.3 Marketing (consent required)
These track interactions to support advertising on Meta's platforms. Only set after you grant consent.
| Cookie | Purpose | Duration | Type |
|---|---|---|---|
_fbp | Identifies browsers for ad targeting | 3 months | Third-party (Meta) |
_fbc | Stores the last Facebook ad click identifier | 3 months | Third-party (Meta) |
Legal basis: consent (Art. 6(1)(a) GDPR). The Facebook Pixel script is not present on the page at all until you opt in.
4. How Consent Works
On your first visit, a cookie banner appears before any non-essential cookies are set. You can:
- Accept All — enable all categories
- Reject All — keep only strictly necessary cookies
- Manage Preferences — enable or disable categories individually
Your choice is stored in the pl_consent cookie and recorded in our database for compliance. If we update this policy (new version number), the banner will reappear so you can review your preferences.
5. Changing Your Preferences
Click the Cookie Settings button in the footer of any page. The consent panel will reopen. Changes take effect immediately: revoking consent for a category deletes the associated cookies and removes the scripts.
6. Browser Controls
You can also manage cookies through your browser settings. Most browsers let you view, delete, and block cookies. Be aware that blocking strictly necessary cookies may break parts of the site.

7. Third-Party Cookies
The analytics and marketing cookies above are set by Google and Meta respectively. We do not control these cookies. See their privacy policies for details:
- Google Analytics: policies.google.com/privacy
- Facebook/Meta: facebook.com/privacy/policy
8. Changes to This Policy
We may update this Cookie Policy from time to time. When we do, we update the date above and increment the version number. A version change triggers a new consent prompt on your next visit.
