Privacy Policy
This Privacy Policy explains how Juno Wallet (“we”, “us”) handles information when you use the Juno Wallet mobile app and our related services (including our backend API).
Key principles
- Non-custodial: your seed phrase and spending keys stay on your device and are never sent to our servers.
- Minimize data: we do not require accounts, names, emails, or phone numbers to use the app.
- No trackers: we do not include advertising SDKs or sell personal information.
Information processed on your device
The app stores wallet data locally on your device (for example: wallet configuration, addresses, and transaction state). Sensitive information (including your seed phrase) is intended to remain on-device.
The app uses OS-provided security features (such as the iOS Keychain / Secure Enclave where available) and app-level encryption for local storage and backups.
Information sent to our backend (when you use network features)
To provide wallet functionality such as syncing and transaction broadcast, the app can communicate with
our backend API (for example: https://api.thejunowallet.com/v1).
Depending on the feature, this may include:
- Viewing key (UFVK) and birthday height: used for server-side scan acceleration. A UFVK can reveal incoming/outgoing transaction activity for that wallet.
- Derived scan state: server-side state derived from the UFVK to speed up future syncs (stored encrypted at rest).
- Wallet addresses (e.g., transparent addresses) for balance/history/UTXO queries.
- Transaction data you ask us to broadcast (signed raw transaction data).
- Technical metadata necessary to operate the service (for example: IP address at the network layer, request timing, and error codes).
Information we do not collect
- Your seed phrase, spending keys, or any material required to spend your funds.
- Your name, email address, phone number, or government ID (we do not do KYC).
- Advertising identifiers (we do not run ads).
How we use information
- Provide wallet features (syncing, scan acceleration, balances/history, broadcasting transactions).
- Protect the service from abuse (rate limiting, operational monitoring).
- Debug reliability issues (using privacy-safe logs and metrics).
How we share information
We share information only to operate the service:
- Infrastructure providers (hosting, storage, networking) to run the backend.
- Monitoring providers for service reliability (logs/metrics are designed to exclude wallet secrets such as seed phrases and spending keys).
- Legal requirements if we are compelled to comply with lawful requests.
We do not sell personal information.
Data retention
- On device: you can delete local data by uninstalling the app (subject to OS backups/settings).
- On backend: when you submit a UFVK for scan acceleration, we retain the encrypted UFVK and encrypted derived scan state to provide the service. If you want server-side data deleted, contact us (see “Contact”).
Security
We use industry-standard security measures intended to protect information in transit and at rest, including TLS for network transport and encryption for sensitive stored data. No method of transmission or storage is 100% secure, but we aim to minimize risk by limiting what is collected and stored.
Children’s privacy
Juno Wallet is not directed to children. If you believe a child has provided us information, contact us.
Changes to this policy
We may update this Privacy Policy from time to time. When we do, we will update the “Effective date” above.
