Cookies & browser storage

Storage supports sign-in, your preferences and recovery of unsaved work.

Sign-in cookies

pokedex_session — 30 days

Keeps you signed in. It is HttpOnly, SameSite=Lax and Secure on HTTPS. Signing out removes this browser’s session; deleting your account invalidates all sessions.

pokedex_signin — 10 minutes

Protects the sign-in exchange against forgery and mismatched responses. A successful sign-in removes it.

Preference cookie

senseiset_browse — 1 year

Set only when you choose “Continue without an account” on the welcome page, so this device opens the catalogue straight away next time. It holds the value 1 and nothing else. Delete it to see the welcome page again.

Local and session storage

The app uses keys beginning with pokemon_ir_, scoped to your account when signed in. They hold collection and inventory caches, selected prints, preferences (the colour theme is kept for this device rather than per account), hidden/kept cards, cached card data, prices, pending-save recovery information, and where you were in the app (the tab, filters, scroll position and any open binder or card) so a reload puts you back there. Local storage remains until cleared; session storage normally lasts for the tab’s session. Signing out does not erase these recovery caches.

Clear this site’s data in browser settings to remove stored data. Export or save pending work first. Account deletion attempts to clear only the deleted account’s keys in the browser making the request. It cannot erase other devices, downloaded files or copies already open in another tab.

Consent and external services

The app has no advertising and no tracking cookies. We count page visits with Cloudflare Web Analytics, which sets no cookies and stores nothing in your browser; it reports totals only, never individual visitors (see Privacy). The sign-in cookies are used to provide secure account access. A consent banner is not used, because nothing here stores information on your device beyond what the service strictly needs. Any further measurement must not be added without assessing consent requirements first.

Sign-in providers and external card-image services may process network information when your browser connects to them. Links to eBay and Cardmarket set nothing on this site; eBay may set its own cookies once you are on eBay. See Privacy.
