Zango (the “app”) is a personal finance app built by an independent developer. This policy explains what information the app handles, where it is stored, and how you can delete it.
Summary
- Your ledger is stored only on your devices and, if you turn on sync, in the cloud account you choose (a private app space in your Google account, or iCloud).
- The developer does not operate any server that receives your ledger and cannot see it.
- There are no ads, no analytics and no usage tracking.
- We do not sell personal information or share it with third parties.
Information the app handles
| Information | Examples | Where it is stored |
|---|---|---|
| Ledger | Account and card names and numbers (if you enter them), transactions, categories, budgets, scheduled transactions, notes, attachments | Your devices, your sync storage |
| Payment message memory | Merchant names, card names and the accounts you linked them to, message formats the app learned, hash values used to recognize a message it has already seen | Your devices, your sync storage |
| App settings | Language, theme, notification and lock settings | Your devices (some settings in your sync storage) |
| Google account information | Email address, sign-in tokens | Your devices (tokens never leave the device) |
| Backups | Backup files of your ledger (without attachments) | Your devices, an extra folder you choose |
All of this information is entered by you or created on your device while you use the app. The app does not read your contacts, location, photos or message inbox.
Sync
Sync is optional. When it is on, changes to your ledger are saved as files in one of the storage options below and delivered to your other devices that use the same account.
Sync with Google account
When you sign in with Google, the app requests only these permissions:
- App data folder (
https://www.googleapis.com/auth/drive.appdata): to create, read, update and delete sync files in a hidden folder in your Google Drive that only Zango can use. With this permission the app cannot see or change your other Drive files. - Email address (
openid,email): to show which account is connected in the settings screen, and to make sure sync only writes to the account you first connected.
Information received from Google is used only to provide this sync feature and is never sent to a developer server. It is not used for advertising, credit decisions, sale, or training AI models, and it is not read by humans.
Zango’s use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
Sync with iCloud account (iPhone, iPad, Mac)
Sync files are stored in Zango’s container in the iCloud of your Apple account. Storage and transfer are handled by Apple, and the developer cannot access these files.
Payment message input
The app reads a message from the clipboard only when you tap the paste button or ask Siri to record a payment. The message is read on the device; on supported devices (iPhone, iPad and Mac with Apple Intelligence turned on) the app uses Apple’s on-device AI. The original text is not stored — only values such as the date, amount and merchant are filled into the transaction.
AI connection (Windows and Mac, optional)
If you turn on AI connection in settings, an AI tool running on the same computer (such as Claude) can read your ledger and add transactions. This feature is off by default, accepts connections only from the same computer (127.0.0.1), and requires an access token created by the app. Ledger data read by the AI tool you connect is handled under that tool’s privacy policy. Your Google account information and sign-in tokens are never exposed through AI connection.
Other device features
- Notifications: Reminders for scheduled transactions are local notifications scheduled on your device.
- App lock: The app asks the operating system to authenticate you with Face ID, Touch ID, Windows Hello or your device passcode. Biometric data is never passed to the app.
Sharing with third parties
The developer does not receive your information, so it is not shared with or sold to third parties. When sync is on, your ledger files are stored with Google or Apple as you choose, and their privacy policies apply. Once the app is distributed through app stores, a store may share crash reports with the developer if you have agreed to it.
Retention and deletion
Your information stays on your devices and in your sync storage until you delete it.
- On your device: Deleting the app deletes the ledger, backups and sign-in tokens on that device (delete files in an extra backup folder yourself).
- Turning off sync: Disconnecting under More > Sync signs out of your Google account.
- Sync files in Google: In Google Drive on the web, open Settings > Manage apps > Zango > Options > Delete hidden app data. You can remove the app’s access in your Google account under Third-party connections.
- Sync files in iCloud: On iPhone, open Settings > Apple Account > iCloud > Manage Storage > Zango and delete the data.
