hello@brunoribeiro.proFrequently asked questions
Do I need internet to use Onzi?
No. Onzi works 100% offline. You may only need a connection to download the app from the store; after that, everything works without internet.
How does sticker scanning work?
Point the camera at the back of the sticker and the app recognizes the code and number automatically. With one tap you add or remove the sticker from your collection — no typing required.
How does QR Code trading work?
Show your QR Code or scan a friend's to open a face-to-face trade session. Onzi compares both collections and instantly shows which stickers each person needs — all offline.
Is my data safe?
Yes. Your data stays only on your device. Onzi creates no account, collects no personal information, and sends nothing to servers. See the Privacy Policy for details.
Is Onzi free?
Yes, Onzi is free, with no ads and no subscription.
Which languages is the app available in?
Onzi is available in Portuguese, English, and Spanish.
