Privacy & Cookies

Plain English. Last updated 28 July 2026.

What we store

• Your account — email, username, and a hashed password. We never store the password itself.
• Your collection — the items you mark as owned, prices you paid, your decks and watchlists. This is private to your account and is never shown to anyone else unless you deliberately publish a profile or share a deck.

Cookies we use

• Strictly necessary: one session cookie that keeps you signed in. Login cannot work without it. No consent is required by law, and it is never used for tracking.
• Optional — analytics: anonymous usage statistics so we know which pages are useful. Only set if you choose “Accept all”.
• Optional — referral: marketplace links (eBay and similar) may set tracking cookies so we earn a small commission if you buy. It costs you nothing and never changes the price you pay. Only with “Accept all”.

You can change your choice at any time from the in-app privacy page.

What we don’t do

• We do not sell your data. Ever.
• We do not share your collection with anyone unless you explicitly make something public.
• We do not run advertising networks on the site.

Your rights and contact

You can export or delete your account data at any time — email [email protected] and we will action it. If you are in the EU or UK, that includes your GDPR rights of access, rectification, erasure and portability.
