DATA COLLECTION
Numo does not collect, store, or transmit any personal data. The app runs entirely on your device.
WALLET DATA
Your seed phrase and wallet data are stored locally on your device. We have no access to this information.
NETWORK COMMUNICATIONS
The app communicates with: • Cashu mints (to manage ecash tokens) • Price APIs (to fetch exchange rates) • Nostr relays (for optional backup features) These services may have their own privacy policies.
ANALYTICS
We do not use any analytics or tracking services.
THIRD-PARTY MINTS
When using ecash mints, the mint operator may see transaction amounts and timing. Choose trusted mints.
BACKUP
If you enable Nostr backup, encrypted wallet data is published to Nostr relays. Only you can decrypt this data with your seed phrase.
