Collectorly tracks prices and auction results for the UK collector car market. This page explains what we collect, why, and what you can do about it. We are the data controller for the information described here.
We use a small number of cookies. Analytics cookies are only set if you accept them in the banner shown on your first visit — decline and no analytics script is loaded at all, and no click-tracking cookie is set either. We still count that a listing link was clicked, but with nothing that ties it to you or to your other clicks.
| Name | Purpose | Retention | Consent |
|---|---|---|---|
_ga, _ga_* |
Google Analytics 4. Measures how many people visit, which pages they read and roughly where they arrived from, so we know which parts of the site are worth developing. We do not use it for advertising and do not share it with advertisers. | Up to 2 years | Only with your consent |
_clk_sid |
An anonymous, randomly generated ID used to group the outbound clicks made in one browsing session. When you follow a link to a listing on PistonHeads, AutoTrader, Car & Classic or Collecting Cars, we record which listing was clicked so we can see which cars people are interested in. It is not linked to your name or email, and it is not shared with anyone. Without your consent this cookie is not set at all, and if you withdraw consent it is deleted on your next click. | 30 days | Only with your consent |
sb-access-token, sb-refresh-token |
Keep you signed in. Only set once you log in, and strictly necessary for accounts to work. | 1 hour / 7 days | Not required (strictly necessary) |
collectorly_consent |
Remembers your answer to the cookie banner so we stop asking. Stored both in your browser and as a cookie — the cookie is what lets our server know not to set the click cookie above when you have declined. | 1 year | Not required (records your choice) |
theme |
Browser storage, not a cookie, remembering your light/dark preference. | Until you clear your browser | Not required (strictly necessary) |
You can change your mind at any time using the button below, and you can clear cookies from your browser settings whenever you like.
If you create an account, we store your email address, display name, avatar image URL and which sign-in method you used (email or Google). Authentication itself is handled by Supabase; your password is never seen or stored by us. If you use the site's features we also store what you choose to save — your watchlist, favourites, portfolio entries and any photos you upload — along with your email alert preferences.
If you opt in, we send a digest of price changes and new listings matching your watchlist, at the frequency you choose. Every email carries a one-click unsubscribe link, and you can change or switch off alerts from your dashboard at any time.
The vehicle listings and auction results shown on Collectorly are collected from public sources. They are information about cars, not about you, and nothing in this section relates to your personal data.
Under UK data protection law you can ask us for a copy of the personal data we hold about you, ask us to correct it, or ask us to delete it — including deleting your account entirely. You can also withdraw consent for analytics at any time using the button above. To make any of these requests, get in touch. If you are not happy with our response, you can complain to the Information Commissioner's Office at ico.org.uk.
If this policy changes we will update the date at the top of this page.
