Help & FAQ

Every card you toggle is saved instantly to your browser (localStorage). It also syncs to the cloud in the background after 30 seconds of inactivity — or immediately when you close the tab. This means your progress is safe even if you go offline.

Tap Copy shareable link in the Sync Status section above. Open that link on your other device — it contains your unique ID and will load your full collection automatically. Bookmark it so you always have it handy.

Your local browser data will be lost, but your collection is still safe in the cloud. Just use your shareable link to restore it — that's why it's worth saving somewhere. If you never copied your link, unfortunately the data cannot be recovered.

Cards are updated manually by the site admin when new photocards appear on Pocamarket. There is no automatic schedule — updates happen periodically, so newly released cards may take some time to appear.

Avoid using the app in multiple tabs at the same time. Each tab saves independently — whichever tab syncs last will overwrite the other's changes, and you may lose progress silently.
