Identity minimization
Join ordinary Channels without a phone number, email address, real-name account, or global M2 profile.
M2 / Secure compartmented communication
Private communication when ordinary channels are not enough.
M2 creates accountless, time-bounded Channels for sensitive coordination—with endpoint encryption, Tor-routed messaging, and temporary encrypted relay handling.
Android 13 or later · signed release 0.6.1 (2039)
Four coordinated controls
Less identity. Clear boundaries.
M2 combines controls at the identity, content, network, and retention layers. Each Channel is an independent communication compartment rather than part of a global social profile.
Endpoint confidentiality
Messages and files are encrypted on the device for the intended recipients.
Network-origin separation
Embedded Tor connects messaging traffic to an M2 v3 Onion Service without a direct clearnet connection to the messaging Gateway.
Temporary encrypted relay
Authenticated durable receipt starts ciphertext deletion; undelivered encrypted payloads expire within 48 hours.
Built around the Channel
A compartment with its own context.
A Channel has its own membership, lifetime, and local history. Create one for a defined task, share invitation material deliberately, and close or expire it when the work ends.

Operational settings
Designed for focused coordination.
M2 is most useful when a team needs a separate communications path with less identity coupling and a deliberately limited lifetime.
Incident response
Establish an out-of-band Channel when ordinary organizational systems may be unavailable or in question.
Field coordination
Keep a temporary operational team separate from personal accounts and contact lists.
Authorized assessments
Coordinate approved security work inside a dedicated, time-bounded compartment.
Sensitive advisory teams
Give temporary cross-organization groups a focused communication context.

M2 0.6.1
The website derives download information from the same trusted manifest used by M2’s signed update policy.
Use with intent
Strong communication boundaries start with the endpoint.
Keep devices protected, separate operational and personal identities where practical, and use a system of record when retained evidence or regulated recordkeeping is required. Read operational guidance.
Give sensitive coordination its own Channel.
