1. Introduction
This Cookie Policy explains how CheckVIN.eu (“CheckVIN”, “we”, “us”) uses cookies and similar technologies, such as your browser’s local storage, on our Website. By clicking “Accept” or adjusting your cookie preferences through the cookie banner, you consent to the use of cookies as described in this Policy.
For information on how we process personal data, please see our Privacy Policy.
2. What Are Cookies?
Cookies are small text files that are stored on your device when you visit a website. They help us deliver essential functionality, improve performance, personalize content and measure how users interact with our Website.
Cookies may be:
Session cookies (deleted when you close your browser)
Persistent cookies (remain until they expire or are deleted)
First-party cookies (set by CheckVIN)
Third-party cookies (set by external providers)
3. Types of Cookies We Use
Our cookie banner groups cookies into four categories:
3.1 Necessary Cookies (Always Active)
These cookies are essential for the operation of the Website and cannot be disabled. They enable core functionality such as:
remembering your language and country
payment processing and checkout
navigation and page loading
fraud prevention, rate limiting and security measures
Examples may include:
Stripe cookies on the checkout page (secure payment processing and fraud prevention)
security cookies that Cloudflare may set to protect the Website against bots and attacks
checkvin_lang: remembers the language version of the Website you use (1 year)
cv_offer: keeps a discount code from a promotional link until you order (30 days)
local storage entries that remember your cookie choice and your country, for prices in your currency (checkvin_country, cv_country)
session storage entries that keep the VIN, the report language and any discount code while you order
cv_bypass and cv_admin_token: used only by CheckVIN staff (maintenance access and the admin area) and never set for visitors
Legal basis: Legitimate interest (Art. 6(1)(f)).
3.2 Preference Cookies
These cookies store your chosen settings, such as:
kilometres or miles in your Report (checkvin_units, stored in local storage)
display preferences
They help provide a more consistent and personalized experience across visits.
Legal basis: Consent (Art. 6(1)(a)).
3.3 Analytics Cookies
Analytics cookies help us understand how visitors use our Website so we can improve performance, usability and reliability.
We use:
Google Analytics, loaded through Google Tag Manager (with anonymization where required)
PostHog (product analytics, user journeys and feature usage), collected through our subdomain k.checkvin.eu
Analytics cookies may collect data such as:
device type, browser type, OS
pages visited and time spent
IP address (shortened or anonymized when possible)
interaction patterns
Analytics data is used solely for performance evaluation and website optimization.
If you do not accept analytics cookies, we still measure visits without cookies and without storing anything on your device:
Google Tag Manager loads in Google’s consent mode, so Google Analytics receives only cookieless signals (such as a page view) with no cookies, no identifiers stored on your device and no ad click identifiers
PostHog counts page views without cookies or local storage, using a hash of your IP address and browser that changes every day and cannot be traced back to you
our own visit count adds a one-way hash of your IP address, browser and the day to a daily count of unique visitors; the hash cannot be reversed and no address is kept
As soon as you accept analytics cookies, Google Analytics and PostHog use their normal cookies; if you later withdraw your consent, they go back to cookieless measurement at once.
Legal basis:
Consent (Art. 6(1)(a)) for Google Analytics and PostHog with cookies
Legitimate interest (Art. 6(1)(f)) for the cookieless measurement described above and for our own visit count, which stores the time of your last counted visit in local storage (checkvin_visitor_tracked) so a visit is counted at most once an hour
3.4 Marketing Cookies
Marketing cookies help us:
measure the effectiveness of campaigns
deliver relevant offers
track conversions and referral performance
understand user engagement with promotional content
We use the Meta Pixel to measure the effectiveness of our ad campaigns, track conversions and deliver targeted advertising based on your interaction with our Website. We also use the OpenAI pixel to measure conversions from our ads. A local storage entry (cv_purchase_ followed by the order number) makes sure a purchase is reported to these tools only once.
These may include cookies used by email delivery tools (e.g., Brevo), tracking whether promotional messages were opened or clicked.
Marketing cookies are optional and disabled by default.
Legal basis: Consent (Art. 6(1)(a)).
4. Third-Party Cookies Used on Our Website
We may use cookies or tracking technologies provided by:
Google (Google Tag Manager and Google Analytics): analytics and performance measurement; cookies only with consent, cookieless signals without it
Stripe: secure payment processing and fraud prevention cookies on the checkout page
Brevo: email engagement tracking (whether our emails were opened)
Cloudflare: security cookies that protect the Website against bots and attacks
Meta Platforms (Meta Pixel): marketing, ad tracking, conversion measurement and retargeting, with consent
PostHog: product analytics and user behavior tracking; cookies only with consent, cookieless counting without it
OpenAI (OpenAI pixel): conversion measurement for our ads, with consent
