Cookie policy
Cookies and similar browser storage hold small pieces of data in your browser. This site uses them to remember your consent choice, measure how the site and its tools are used, offer optional feedback surveys, and record which campaign brought you here. Optional storage is denied by default. Where Google Consent Mode is configured in advanced mode, supported Google tags may send limited cookieless pings before consent, without reading or writing advertising or analytics cookies. PostHog browser analytics, journey linkage and surveys start only after analytics consent.
Consent is managed by CookiePal with Google Consent Mode v2. The choice is passed to supported tags so they adjust storage and network behaviour. Non-Google services such as Clarity and PostHog browser analytics are separately gated by the analytics category. Without analytics consent, or when Global Privacy Control or Do Not Track is enabled, the PostHog browser library is not started and no fp_journey_id or PostHog browser persistence is created.
The Signal Plan scanner may send an anonymous server-side reliability event whether or not analytics consent is granted. It uses a new random scan_id for that run, creates no cookie or reusable person profile, disables geographic enrichment, and contains only derived counts, true-or-false indicators, duration and finite failure codes. It is not linked to a browser journey unless analytics consent exists.
The cookies and browser storage we use
Strictly necessary
| Cookie | Purpose | Duration |
|---|---|---|
| cookiepal-consent | Stores your consent choices per category | 1 year |
Analytics (only with consent)
| Cookie | Purpose | Duration |
|---|---|---|
| _ga | Google Analytics: distinguishes visitors | 2 years |
| _ga_Q7VJTMJ0MM | Google Analytics: keeps session state | 2 years |
| _clck | Microsoft Clarity: visitor identifier for session recordings | 1 year |
| _clsk | Microsoft Clarity: links actions within one session | 1 day |
| fp_journey_id | Fire Pixel: a random pseudonymous identifier used to join explicit product-journey events without using a name or email address | Up to 90 days |
| ph_<project-token>_posthog | PostHog first-party cookie and browser-storage record used for the consented pseudonymous journey and survey display state | Valid for up to 90 days; the browser-storage copy is cleared on the next Fire Pixel visit at or after its fixed deadline |
| fp_posthog_expires_at | Fire Pixel browser-storage deadline used to ensure expired PostHog state is never reused | Up to 90 days |
PostHog EU Cloud receives explicit allowlisted events only. Autocapture and PostHog session replay are disabled. Form contents, email addresses, scanned URLs or domains, raw scanner results and public tag IDs are excluded. The Signal Plan URL field, result area and contact inputs are also excluded from capture and masked as a defence in depth control.
Attribution (first-party, only with consent)
| Cookie | Purpose | Duration |
|---|---|---|
| ddTrafficSource / ddTrafficMedium / ddTrafficCampaign / ddTrafficCampaignTerm / ddTrafficCampaignContent | Records the source, medium and campaign that brought you to the site (last non-direct) | 90 days |
| ddAdClickIdGclid / ddAdClickIdFbclid / ddAdClickIdMsclkid / ddAdClickIdGbraid / ddAdClickIdWbraid | Stores ad click identifiers from Google, Meta and Microsoft ads so an enquiry can be attributed to the click that produced it | 90 days |
| _fp_attr | HttpOnly edge-attribution record. Set only after the CookiePal advertising category is accepted; otherwise any older edge cookie is cleared | 90 days |
These attribution cookies are first-party and are not directly accessible to third-party advertising scripts. They are attached to your enquiry only if you submit the contact form, and the associated identifiers may then be used to report the conversion to the advertising platform that produced the click.
Changing your mind
Use the button above to reopen the consent banner and change or withdraw consent at any time. Withdrawing analytics consent opts that browser out of PostHog capture and deletes fp_journey_id plus PostHog's first-party cookie and browser-storage record. You can also clear or block cookies in your browser settings; the site and Signal Plan work without the optional ones.
