Privacy

As of 4 October 2026

If this translation conflicts with the German version, the German text prevails.

Controller

The controller for the processing of personal data is the operator of ClassicGuide. The contact details are in the Imprint.

Which data

• (a) Account: email address, password (only as a hash at the authentication provider), account type, name, optional phone and place; for dealers also company, business address, UID where it exists, website and short text, plus a public profile slug.
• (b) Listings: vehicle details, description, photographs, price, location (postcode and place).
• (c) Technical data: hosting server logs (IP address, time, page requested) for operational security.
• (d) Listing statistics: number of views, contact enquiries sent and phone numbers revealed, visible only to the advertiser. Message contents are not stored (they go out by email only). To avoid double counting we store a non-reversible daily hash (not the IP address in clear text) and delete it after two days.
• (e) Reach measurement (only with consent): usage data collected by Google Analytics, such as pages viewed, referrer, approximate location, device and browser. Google truncates the IP address and does not store it permanently.
• (f) Newsletter: the email address. You give consent in the footer and confirm it via a link, or you switch it on in the profile. If the address has an account, the sending service also stores the account identifier.

Technically necessary cookies: the login session and a cookie (1 day), so that the same visit to a listing is not counted more than once as a view.

Analytics cookies: the Google tag is on every page (Consent Mode). Analytics cookies (typically _ga and _ga_4QE4C15ET8) are set by Google only after you agree. We store your choice only locally in the browser (localStorage). Advertising cookies stay off. Without consent Google may receive cookieless technical signals, but it does not store analytics cookies.

Purposes

The data are processed to run the platform, to display listings (the name for private individuals; for dealers the company, address, phone and UID where applicable), the public dealer profile, moderation of listings, listing statistics for the respective advertiser, operational security and, only with consent, statistical evaluation of use via Google Analytics. We send the newsletter only after consent.

Processors

• Vercel: hosting of the website.
• Supabase: database, login and storage of listing images; the data are kept in a region in the EU.
• Resend: sending of transactional emails (account confirmation, password reset, contact enquiries, listing status messages, newsletter confirmation) and storage of newsletter contacts and sending of the newsletter.
• Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland: Google Analytics, Google Tag Manager / Google Tag (gtag.js), Google Search Console and Google Maps and Places (see below). The parent company is Google LLC, USA.

Disclosure to Vercel, Supabase and Resend is for performance of the contract and for operation. The Google tag is loaded on every page; storage of analytics cookies and full reach measurement take place only with your consent. Disclosure to Google for maps on garage pages takes place when those pages are opened.

Retention

Account data are kept until the account is deleted. Listings stay stored until the advertiser or account deletion removes them. Server logs are kept only briefly. Google Analytics stores event data for 14 months by default. The local consent stays stored until you change it or clear the browser storage. Newsletter addresses stay stored until you unsubscribe or delete your account. Unsubscribing via the link in an issue, or the switch in the profile, stops sending; the address stays marked as unsubscribed until deletion, so that it is not entered again by mistake. Deleting the account removes the contact.

Rights under the revDSG

You have the rights of access, rectification, erasure and objection. The account can be deleted directly under Profile → Delete account. You can withdraw consent to reach measurement at any time on this page. You withdraw newsletter consent in the profile or via the link in each issue. For further requests, the contact is the one in the Imprint.

Google Analytics, Google Tag Manager and Search Console

We use Google Analytics 4 (measurement ID G-4QE4C15ET8). The measurement tag (gtag.js) is in the HTML of every page and is loaded from googletagmanager.com, the same service through which Google Tag Manager delivers tags. We also use Google Search Console to check how ClassicGuide appears in Google search (indexing, queries). Search Console does not set cookies on this website; Google collects search data independently of a visit here.

Purpose of reach measurement: to understand which pages are used and to improve the platform. No personalised advertising is shown; Google Signals and ad personalisation are switched off.

Disclosure abroad: usage data may be transferred to the USA. Google relies on the EU-US Data Privacy Framework or on standard contractual clauses. Information on Google's processing of data is in the Google privacy policy.

We use Google's consent mode: without your agreement, analytics and advertising cookies stay blocked. If you agree in the notice at the bottom or here, measurement is switched on. Refusing has no disadvantage for use of the platform.

Google Maps and Google Places

On garage detail pages and on event detail pages with an address filled in, a Google Maps map is loaded when the page opens. Your browser then sends your IP address and device details to Google.

We fetch Google reviews (stars and count) from Google on the server once a workshop is recorded there; no visitor data goes to Google in that step. Information on Google's processing of data is in the Google privacy policy.

Disclosure and profiling

Personal data are not passed on to other advertisers. The newsletter itself runs through Resend as processor, only to addresses with consent. Google receives usage data only with consent, as processor for reach measurement. There is no profiling for advertising.
