Privacy
Browsing requires no account. Searches and language choices appear in page URLs; avoid putting personal information in searches. Cloudflare serves pages and Supabase stores the reference index and submitted corrections. Technical request data can be processed for security and reliability. The scan worksheet stays in this browser and is saved only when you choose Save. Correction messages and optional email addresses are stored for review; do not submit VINs, registration numbers or other sensitive information. We use aggregate page, language, country, referral-category, code-lookup, search-result and crawler counts to improve this reference. The analytics database does not store raw IP addresses, fingerprints, free-text queries or full referrer URLs. IP-derived hashes are used temporarily for rate limiting. Language preferences are stored locally in your browser. Administrators use a necessary login cookie. Aggregates are retained for up to 25 months; security rate-limit records expire after 2 days. Contact us through the correction form for privacy requests.
Advertising and privacy choices
Where advertising is enabled, we use Google AdSense. Google and its advertising partners may use cookies, local storage, web beacons, IP addresses and device identifiers to deliver and measure ads and, with the required consent, personalize them. Third parties may place and read cookies in your browser. Google’s certified consent management platform provides the applicable consent and privacy messages. You can accept, decline or manage the choices offered, and revisit them using the privacy choices link. Declining optional advertising does not restrict code lookup or reading. Google may serve limited ads where permitted. Retention and processing by Google and its partners follow their own policies; the retention periods above describe our own aggregate analytics only.
In supported US states, Google’s Do Not Sell or Share My Personal Information link provides the applicable opt-out choices. Our manual ad unit also refrains from requesting an ad when the browser sends Global Privacy Control or Do Not Track. Google’s own privacy controls and data policies still apply.
