Getting Started

Every change syncs to the cloud within a few seconds. No account needed. Changes are also saved locally so the app works offline.

Your collection is tied to a unique ID in your sync link. Think of it like a private key — whoever has the link can view and edit your collection. Keep it private, like a password.

Go to Settings → Copy sync link and open that link on your other device. After the first visit, the plain URL works on that device — but save the link somewhere safe in case you clear your browser.

Sharing

Use Settings → Share All Cards to generate a view-only link. Friends can browse your collection but can't change anything. Never share your sync link — that gives full edit access.

Import & Export

Use Settings → Export collection JSON to download a backup file. If you ever lose your sync link, you can import this file to restore your data.

Go to Settings → Import collection JSON. This replaces your current collection — export first if you want to keep what you have.

Troubleshooting

Check your internet connection. Your data is always saved locally even if sync fails, so nothing is lost — it'll sync next time you're online.

You need to open your sync link on the new device — the plain URL alone won't load your collection in a new browser. Find your link under Settings → Copy sync link.

Avoid it. Each tab saves independently — whichever syncs last overwrites the other, and you may lose changes silently.

Generates a new sync ID and clears your collection. Use this only if your sync link was shared accidentally. All devices using the old link will be disconnected — export first.

Help & FAQ

Card toggles save instantly to your browser and sync to the cloud within a few seconds. Your progress is safe even offline — but save your sync link from Settings. It's the only way to restore your collection on a new device or after clearing your browser.

To share your collection with friends, use Share All Cards in Settings — they get a read-only view. To access your own collection on another device, use Copy sync link and bookmark it. You only need it the first time per device — after that the browser remembers you and the plain URL works fine. Keep the link safe: incognito, new browsers, and clearing browser data all require it again.

Cards are updated manually when new photocards appear on Pocamarket. There's no automatic schedule, so newly released cards may take some time to appear.

Avoid it. Each tab saves independently — whichever syncs last overwrites the other, and you may lose changes silently.
