Effortdex caches its own files and sprite images so it keeps working offline.
A copy of your data from just before your last data update. You won't need this unless a developer asks for it while looking into a bug report.
Move your parties and roster to another device via a shareable link.
Move your parties and roster to or from another device.
Turn this device's roster into a shareable link.
Paste a shared link, or load a saved transfer file.
Effortdex caches its own files (and PokéAPI lookups, including sprite images) so it keeps working offline. "Clear cache" wipes all of it at once — it gets rebuilt fresh on the next load.
Your parties, roster and battle history are safe. They live separately in this browser's storage and are never touched by anything on this page.
Warm up (or clear) sprites for a specific game or generation instead of everything at once. Some titles share the exact same sprite artwork on PokéAPI (e.g. Ruby & Sapphire) — those are listed as one row, since caching or clearing one always does the same to the other.
Caching a whole generation can take a couple of minutes — get a notification when a "Cache" or "Cache all" run finishes, even if you've switched away from this tab in the meantime.
Turns off the service worker and all offline caching entirely — every reload then always hits the real files on the server, never a cached copy. Only useful while actively developing Effortdex itself; the app stops working offline while this is on, so leave it off otherwise. Takes effect immediately (reloads the page).
