Opening this device's zone
Blackpath Zone
A zone is private to the people you add. Notes and files are kept on their devices. Black Path passes sealed copies between them and never holds the key.
No account, no tracking. Everything is encrypted in this browser before it leaves. Demo encryption, not yet independently audited.
Join a zone
Ask someone in the zone to open Add a device. Scan the zone code it shows, or paste the code or an invite link below. With a zone code, this device then shows its own code for the zone's owner to scan.
Point the camera at the code on the other device
Show this to the owner
The zone's owner scans this code to add you. It holds this device's public keys only.

Zone
Offered in this zone
Folders open here, straight from the member's machine. A model opens in Chat.
Nothing here yet
Write a note or attach a file. It is kept on the devices in this zone; Black Path only passes sealed copies along.
Folder
This folder is empty.
Read only. Files come straight from the member's machine over an end-to-end encrypted session; Black Path only helps the two devices find each other.
Your zones
Each zone has its own keys and its own identity for you. Black Path cannot tell that two of your zones belong to the same person.
Settings
Members and devices
Only the zone's owner can remove members or their devices. You can revoke your own other devices.
If someone may have a copy of this device's keys, start over: this device gets new keys for the zone and the owner swaps them in. What you already have stays here.
Capabilities
What members' machines offer in this zone, and when each came online or dropped off. Checked every 30 seconds while this screen is open.
No member offers anything in this zone yet.
Timeline
Nothing has come or gone yet.

Storage and status
Black Path keeps sealed copies for a limited time so devices can fetch them. A device offline for longer gets files only from another member's device or the mirror.
Last mirror push, per device
No device has reported a mirror push yet.
Recovery code
This browser keeps every one of your zones in its own storage, and a browser can clear that storage: when storage runs low, when site data is cleared, or in private windows. Clearing it removes every zone at once. Print your recovery code so you can get your zones back.
This browser
This page's code comes from Black Path's server, so trusting this app means trusting that server. Each release publishes the hash of its code; this app shows the hash it is running below, and refuses to install an update whose files do not match it. The Android app is the stronger choice: its code is on your phone and does not change between visits.
Chat
No model is online in this zone
When a member's computer offers private inference to you and is online, you can chat with its model here. Nothing you write leaves for anywhere else.
Ask something. The answer streams in as it is written.
