Privacy policy

Last updated 24 August 2026. There is not much to say, which is the point.

What we collect

What we do not collect

No accounts, no passwords, no payment details, no advertising trackers, no analytics scripts, and no cookies set by us. The site does not use local storage to identify you. If that changes, this page will change first.

Why we hold the email

To tell you when live alerts and paid tiers launch, and for nothing else. We do not sell, rent, or share addresses. Legal basis under UK GDPR: your consent, which you gave by submitting the form and can withdraw by emailing luke@sleeperlot.com. We delete the address on request and, in any case, within twelve months of the last message we send you if you have not signed up for anything.

Marketplace data is not about you

The auction data behind our estimates is public listing information. It describes items, not people. We never store seller identities, buyer identities, or bidder histories, and we discard individual listing records once they are no longer publicly available on their source, keeping only aggregate statistics.

Where data lives

Static site and waitlist storage: Cloudflare (global edge; data may be processed outside the UK under Cloudflare’s standard contractual clauses). Collection and analysis servers: Hetzner, Germany. Email: Zoho.

Your rights

You can ask what we hold about you, ask us to correct or delete it, or object to its use. Email luke@sleeperlot.com; we answer within a month. If you are unhappy with our answer you can complain to the UK Information Commissioner’s Office (ico.org.uk).

Changes

We will update the date above whenever this policy changes materially.
