Privacy Policy - Archeum

Last updated: June 15, 2026

Overview

Archeum is a decentralized personal-infrastructure app - the wallet and key-management app for the Archeum network. The app stores cryptographic keys and identity data on your device and runs your node (the infrastructure that stores your data) on your own phone. Archeum the publisher does not operate servers that receive or store your data.

Data stored on your device

The app stores the following locally, in Android's encrypted secure storage:

• Your wallet private key (Ed25519) and recovery phrase
• Your AGE encryption keypair
• Your Archeum handle(s) and node identity
• App settings and preferences

These values never leave your device, except as described below.

Your node runs on your phone

Your Archeum node runs as a background (foreground) service on your phone, anchored to the device's secure hardware (StrongBox). The node stores your data locally and answers app requests on your behalf. There is no third-party server, VPS, or cloud account holding your data - the device in your pocket is the node.

Data sent over the network

• The Archeum mesh: handle ownership lives in Archeum's own feeless, peer-to-peer consensus (there is no blockchain). To claim or resolve handles, your node exchanges signed messages with other nodes over the mesh. As with any peer-to-peer network, peers you connect to can see your IP address. There are no fees, no gas, and no third-party RPC provider.
• Your node: apps connect to the node on your phone over QUIC (UDP 443) to read and write your data. That data is under your control.

Data we (the publisher) receive

By default, we receive nothing. No analytics, no telemetry, no crash reporting, no ad tracking.

If you tap Settings → Send Feedback, the app opens the system share sheet (or email app) with recent debug logs (up to ~50 KB, normally kept only in memory; briefly written to a temp file for the share-sheet attachment, cleaned up by the OS) addressed to [email protected]. Nothing is sent unless you choose to send it.

Permissions

• Internet: connect to the mesh and serve your node.
• Notifications: Android requires a visible notification while the node runs as a foreground service.
• Bluetooth: provision a nearby Archeum node during first-time setup. Local-only; no data is transmitted over the internet via Bluetooth.
• Fine Location: Android requires it to scan for Bluetooth devices during provisioning. We do not read, store, or transmit your location.
• Battery optimization exemption (optional): so the node can stay reachable in the background. You control whether to grant it.

Local network communication

During first-time node provisioning, the app may talk to a node on the local device using plaintext HTTP (e.g. http://[::1]:8080). This traffic never leaves the device. Once running, all communication with your node uses encrypted QUIC (TLS 1.3).

Third parties

• Google Play Services - for app distribution and (where used) hardware key attestation.

Archeum does not use any blockchain, RPC provider, transaction bundler, or analytics vendor.

Data deletion

You can delete your account at any time: Settings → Delete Account. This wipes all data stored on your node (across every app namespace) and erases all local data (wallet keys, recovery phrase, secure storage). See archeum.io/delete-account for the full process.

Handle ownership lives in the mesh consensus, not on a blockchain. After deletion your node goes offline and your data is wiped; with nothing answering and no renewal, the handle lapses after its lease of silence (roughly two months) and the name becomes available again.

Children

Archeum is not intended for users under 18.

Changes to this policy

When this policy changes materially, we will update the date at the top and highlight changes in the app's release notes.
