Privacy Policy
The honest summary: Onzi does not collect, store, or send your personal data. Everything you do in the app stays on your device. No account, no sign-up, no tracking.
What we collect
Nothing. Onzi works 100% offline — it creates no account, asks for no email, requires no login, and sends no information to any server of ours.
- We do not collect your name, email, phone number, or location.
- We use no analytics tools and no trackers.
- We show no ads and sell no data — there is no data to sell.
Camera and sticker scanning
The app requests camera access only to recognize a sticker's code and number at the moment you scan it. The image is processed locally, on your device, and is never saved or uploaded.
Where your data lives
Your progress, your duplicates, and your trades are stored only in your device's local storage. You are the sole owner of this information.
- If you delete the app, this data is removed with it.
- Backups and exports (when you use them) stay on your own device or wherever you choose to save them.
QR Code trading
Trades happen directly between two devices, scanning a QR Code face to face. Trade information is exchanged between the devices involved — it never passes through our servers.
Third-party services
Onzi embeds no advertising or tracking SDKs. The app stores (App Store and Google Play) may collect download and usage statistics under their own policies, over which we have no control.
Children's privacy
Because it collects no personal data, Onzi is safe for all ages. We neither request nor store information from anyone, including children.
Changes to this policy
If we change this policy, we will update the date at the top of this page and publish the new version here. Since we have no way to contact you, the best way to stay informed is to revisit this page.
