Nostr Uno — Privacy Policy

Last updated: April 7, 2026

What We Collect

Nothing. Nostr Uno does not collect, store, or transmit any personal data to our servers. We have no servers. We have no analytics. We have no tracking.

What Stays on Your Device

All data is stored locally on your device:

• Seed phrases — encrypted with AES-GCM, stored in your device's secure storage
• Private keys — derived in memory, never stored unencrypted
• Identity profiles — names, colors, and settings stored in local IndexedDB
• Connected app records — stored locally to manage NIP-46 signing permissions
• Activity logs — signing history stored locally for your review

Network Communication

Nostr Uno communicates only with Nostr relays that you configure. This communication is inherent to the Nostr protocol (NIP-46 remote signing). We do not operate relays and have no visibility into your relay traffic.

Third-Party Services

Nostr Uno does not integrate with any analytics, advertising, or tracking services.

Data Deletion

Uninstalling the app deletes all local data. You can also clear all data from within the app's Settings.

Children's Privacy

Nostr Uno is not directed at children under 13. We do not knowingly collect any data from anyone, including children.

Changes

If this policy changes, the updated version will be posted here with a new date.
