zebrinoZebrino Privacy Policy
Effective date: 4 October 2026
Zebrino puts the cards you carry for their barcode (loyalty, library, gym, membership and similar cards) on your Zepp OS watch. This policy explains, in plain words, what Zebrino does with your information. The short version: your cards stay on your phone and your watch. Zebrino has no servers, no accounts, no ads and no tracking.
What Zebrino stores
Only what you put in, plus what it needs to work:
- Your cards: name, card number, barcode value and type, colour, and the optional note, balance, unit and expiry date you add.
- Your settings: screen brightness for scanning, card order, and whether suggestions are on.
- On the watch only: the barcodes ready to display, when the cards were last synced, which cards you used recently and, if suggestions are on, at which times of day you usually show each card, so the right card can come first.
Zebrino does not collect your name, e-mail address, location, contacts, health or fitness data, or any identifier for advertising.
Where it is kept
- On your phone, inside the Zepp app, as the settings of the Zebrino mini app.
- On your watch, in Zebrino's private storage.
Cards travel only between your phone and your watch, through the Zepp app's own connection. Zebrino never sends your data to its developer or to anyone else, and it does not connect to the internet.
The Zepp app and your watch are made by Zepp Health. How the Zepp app itself handles data is covered by Zepp Health's privacy policy.
What Zebrino never does
- No accounts and no sign-in.
- No advertising, no analytics, no tracking of any kind.
- No sale, rental or sharing of your information.
- No third-party SDKs. Zebrino includes two open-source libraries that run entirely on your devices: bwip-js (draws the barcodes) and ZML (messages between watch and phone). Neither sends data anywhere.
Permissions
Zebrino uses one permission: local storage on the watch, to keep your cards available when your phone is out of reach.
Your control
- Edit or delete any card in Zepp app › Profile › your watch › App settings › Zebrino. Changes reach the watch at the next sync.
- Suggestions can be switched off, and what the watch has learnt can be erased with Reset suggestions in the same settings.
- Backups are created only when you ask for one, as text you copy yourself. Zebrino keeps no copy.
- Uninstalling Zebrino from your watch removes the app and its data from the watch. To clear your cards from the Zepp app as well, delete them in Zebrino's settings before uninstalling.
Card numbers
Card numbers can be personal, so the watch's card list shows only the last four digits of numbers longer than six characters; the full number appears on the card screen you open. Anyone holding your unlocked watch could open your cards, just like a physical wallet. Keep your watch's passcode on if that matters to you.
Children
Zebrino is a general-audience utility. It does not knowingly collect information from anyone, including children, because it does not collect information at all.
Changes to this policy
If this policy changes, the new version will be published at zebrino.app/privacy with a new effective date. Because Zebrino does not collect data, a change can never apply to data collected before it.
